The GoProxy is a high-performance http proxy, https proxy, socks5 proxy, ss proxy, websocket proxies, tcp proxies, udp proxies, game shield, game proxies. Support forward proxies, reverse proxy, transparent proxy, internet nat proxies, https proxy load balancing, http proxy load balancing , socks5 proxies load balancing, socket proxy load balancing, ss proxy load balancing, TCP / UDP port mapping, SSH transit, TLS encrypted transmission, protocol conversion, anti-pollution DNS proxy, API authentication, speed limit, limit connection. Reverse proxies to help you expose a local server behind a NAT or firewall to the internet so that you or your visitors can access it directly and easily.
- Chained proxies, the program itself can be used as an proxies, and if it is set up, it can be used as a secondary proxies or even an N-level proxies.
- Communication encryption, if the program is not a level one proxies, and the upper level proxies is also the program, then the communication between the upper level proxies and the upper level proxies can be encrypted, and the underlying tls high-intensity encryption is used, and the security is featureless.
- Smart HTTP, SOCKS5 proxy, will automatically determine whether the visited website is blocked. If it is blocked, it will use the upstream proxies (provided that the upstream proxies is configured) to access the website; if the visited website is not blocked, in order to speed up the access, the proxies will Direct access to the website without using a upstream proxies.
- Domain name black and white list, more free to control the way the website is accessed.
- Multi-protocol support, support for HTTP(S), TCP, UDP, Websocket, SOCKS5 proxy.
- TCP/UDP port forwarding.
- Support intranet penetration, protocol supports TCP and UDP.
- SSH relay, HTTP (S), SOCKS5 proxy supports SSH relay, the upper Linux server does not need any server, a local proxy can be happy online.
- [KCP](https://github.com/xtaci/kcp-go) protocol support, HTTP(S), SOCKS5, SPS proxy supports KCP protocol to transmit data, reduce latency and improve browsing experience.
- Dynamic selection of upstream proxies, through the external API, HTTP (S), SOCKS5, SPS proxies can achieve user-based or IP-based speed limit, connection limit, dynamic access to upstream.
- Flexible upstream allocation, HTTP(S), SOCKS5 proxy can implement user- or IP-based speed limit, connection limit, and upper-level through configuration files.
- Transparent HTTP (S) proxy, in conjunction with iptables, forwards the outgoing 80, 443 traffic directly to the proxy at the gateway, enabling non-aware intelligent router proxy.
- Protocol conversion, which can convert existing HTTP(S) or SOCKS5 or SS proxy into one port and support HTTP(S) and SOCKS5 and SS proxy at the same time. Converted SOCKS5 and SS proxy. If the upstream is SOCKS5 proxy, then UDP is supported. Features while supporting powerful cascading authentication.
- Custom underlying encrypted transmission, http(s)\sps\socks proxy can encrypt tcp data via tls standard encryption and kcp protocol on top of tcp, in addition to support custom encryption after tls and kcp, that is Said custom encryption and tls|kcp can be used in combination, the internal AES256 encryption, you only need to define a password when you use it.
- Underlying compression efficient transmission, http(s)\sps\socks proxy can encrypt tcp data through custom encryption and tls standard encryption and kcp protocol on tcp, and can also compress data after encryption, that is, compression function And custom encryption and tls|kcp can be used in combination.
- Secure DNS proxy, which can secure and prevent pollution DNS queries through encrypted proxy communication between the DNS proxy server provided by the local proxy and the upstream proxy.
- Load balancing, high availability, HTTP(S)\SOCKS5\SPS proxies supports upstream load balancing and high availability, and multiple upstream repeat-P parameters can be used.
- Specify the egress IP. The HTTP(S)\SOCKS5\SPS\TCP proxy supports the client to connect with the ingress IP, and uses the ingress IP as the egress IP to access the target website. If the ingress IP is an intranet IP, the egress IP does not use the ingress IP.
- Support speed limit, HTTP(S)\SOCKS5\SPS\TCP proxy supports speed limit.
- The certificate parameter uses base64 data. By default, the -C, -K parameter is the path of the crt certificate and the key file. If it is the beginning of base64://, then the latter data is considered to be base64 encoded and will be used after decoding.
- Support client IP black and white list, more secure control of client access to proxy service, if black and white list is set at the same time, then only whitelist is effective. Socks / HTTP(S) / SPS / TCP / UDP / DNS / intranet NAT The bridge/intranet NAT the tbridge and supports the client IP black and white list.
- Range ports listen on, HTTP(S)\SOCKS5\SPS\TCP proxy supports port range listening, avoiding starting too many processes and improving performance.

## Purchase Commercial Edition
This manual describes the functions, all of which are included in the commercial version; the free version of advanced functional parameters such as authentication is not included;
If you encounter some commands when you use the free version to execute some commands, a prompt similar to the following xxx parameter does not exist, indicating that this parameter is a function of the commercial version.
Comparison between the features of the free version and the commercial version, detailed operations on how to purchase and use the commercial version [please click here to view](https://snail007.host900.com/goproxy/page/free_vs_commercial_en/)
The next tutorial will introduce the usage method through the command line parameters, or you can get the parameters by reading the configuration file.
The specific format is to specify the configuration file by the @ symbol, for example: proxy @configfile.txt
The format in configfile.txt is that the first line is the name of the subcommand, and the second line starts with one parameter per line.
Format: `parameter Parameter value`, direct write parameter without parameter value, for example: --nolog
For example, the contents of configfile.txt are as follows:
```shell
Http
-t tcp
-p :33080
--forever
```
### 3. Debug output
By default, the information output by the log does not include the number of file lines. In some cases, in order to troubleshoot the program, the problem is quickly located.
You can use the --debug parameter to output the number of lines of code and milliseconds.
### 4. Using log files
By default, the log is displayed directly in the console. If you want to save to a file, you can use the --log parameter.
For example: --log proxy.log, the log will be output to the proxy.log to facilitate troubleshooting.
### 5. Generate the certificate file required for encrypted communication
The http, tcp, udp proxy process communicates with the upstream. For security, we use encrypted communication. Of course, we can choose not to encrypt the communication. All the communication and the upstream communication in this tutorial are encrypted, and the certificate file is required.
1. Generate a self-signed certificate and key file with the following command.
`proxy keygen -C proxy`
The certificate file proxy.crt and the key file proxy.key will be generated under the current program directory.
2. Use the following command to generate a new certificate using the self-signed certificate proxy.crt and the key file proxy.key: goproxy.crt and goproxy.key.
`proxy keygen -s -C proxy -c goproxy`
The certificate file goproxy.crt and the key file goproxy.key will be generated under the current program directory.
3. By default, the domain name inside the certificate is random and can be specified using the `-n test.com` parameter.
4. More usage: `proxy keygen --help`.
### 6. Running in the background
After the proxy is executed by default, you cannot close the command line if you want to keep the proxy running.
If you want to run the proxy in the background, the command line can be closed, just add the --daemon parameter at the end of the command.
For example:
`proxy http -t tcp -p "0.0.0.0:38080" --daemon`
### 7. Guardian running
The daemon runs the parameter --forever, for example: `proxy http --forever` ,
The proxy will fork the child process, and then monitor the child process. If the child process exits abnormally, restart the child process after 5 seconds.
This parameter is matched with the background running parameter --daemon and log parameter --log, which can guarantee that the proxy will always execute in the background without accidentally exiting.
And you can see the output log content of the proxy through the log file.
For example: `proxy http -p ":9090" --forever --log proxy.log --daemon`
When the VPS is behind the nat device, the vps network interface IP is the intranet IP. At this time, you can use the -g parameter to add the vps external network ip to prevent the infinite loop.
Suppose your vps external network ip is 23.23.23.23. The following command sets 23.23.23.23 with the -g parameter.
`proxy http -g "23.23.23.23"`
### 9. Load balancing and high availability
The HTTP(S)\SOCKS5\SPS proxy supports upper-level load balancing and high availability, and multiple upstream repeat-P parameters can be used.
The load balancing policy supports five types, which can be specified by the `--lb-method` parameter:
Roundrobin used in turn
Leastconn uses the minimum number of connections
Leasttime uses the least connection time
Hash uses a fixed upstream based on the client address
Weight Select a upstream according to the weight and number of connections of each upstream
prompt:
1. The load balancing check interval can be set by `--lb-retrytime` in milliseconds.
2. The load balancing connection timeout can be set by `--lb-timeout` in milliseconds.
3. If the load balancing policy is weight, the -P format is: 2.2.2.2: 3880?w=1, where 1 is the weight and an integer greater than 0.
4. If the load balancing policy is hash, the default is to select the upstream based on the client address. You can select the upstream by using the destination address of the access `--lb-hashtarget`.
5. The TCP proxies has no parameter `--lb-hashtarget`.
6. Default is load balancing + high availability mode. If the parameter `--lb-onlyha` is used, only the high availability mode is used, then a node is selected according to the load balancing strategy, and this node will be used until it is not alive, then another node will be selected for using, thus cycling.
7. If the all nodes are not alive, a random node will be selected for using.
### 10. Agent springboard jump
Http (s) agent, SPS agent, intranet penetration, tcp agent support the connection of upstreams through intermediate third-party agents,
The parameters are: --jumper, all the formats are as follows:
```text
http://username:password@host:port
http://host:port
https://username:password@host:port
https://host:port
socks5://username:password@host:port
socks5://host:port
socks5s://username:password@host:port
socks5s://host:port
ss://method:password@host:port
```
Http,socks5 represents the normal http and socks5 proxy.
Https,socks5s represents the http and socks5 agents protected by tls.
That is http proxy over TLS, socks over TLS.
### 11. Domain Name Black and White List
The socks/http(s)/sps proxy supports domain name black and white lists.
Use the --stop parameter to specify a domain name blacklist file, then the connection will be disconnected when the user connects these domains in the file.
Specify a domain name whitelist file with the --only parameter, then the connection will be disconnected when the user connects to a domain other than those domains in the file.
If both --stop and --only are set, then only --only will work.
The format of the black and white domain name list file is as follows:
```text
**.baidu.com
*.taobao.com
A.com
192.168.1.1
192.168.*.*
?.qq.com
```
Description:
1. One domain name per line, domain name writing supports wildcards `*` and `?`, `*` represents any number of characters, `?` represents an arbitrary character,
2.`**.baidu.com` Matches no matter how many levels all suffixes are ..baidu.com`.
Use the --ip-allow parameter to specify a client IP whitelist file, then the connection will be disconnected when the user's IP is not in the file.
If both --ip-deny and --ip-allow are set, then only --ip-allow will work.
The format of the client IP blacklist and whitelist file is as follows:
```text
192.168.1.1
192.168.*.*
192.168.1?.*
```
Description:
1. One domain name per domain, domain name writing supports wildcards `*` and `?`, `*` represents any number of characters, `?` represents an arbitrary character.
2.`#` at the beginning of the comment.
### 13. Protocol loading file
There are many places in the proxy's various proxy functions to set a file. For example: --blocked Specifies a domain name list file that goes directly to the upper level. The parameter value is the path of the file.
If the parameter supports the protocol loading file, the file path can be not only the file path, but also:
a. The base64 encoding at the beginning of "base64://" indicates the contents of the above file, for example: base64://ajfpoajsdfa=
b. "str://" at the beginning of the English comma separated multiple, such as: str://xxx, yyy
The proxy's blocked, direct, stop, only, hosts, resolve.rules, rewriter.rules, ip.allow, ip.deny files support protocol loading.
### 14.Concurrent client connections
socks5\sps\http proxies, the parameter that controls the number of concurrent client connections is: `--max-conns-rate`, which controls the maximum number of client connections per second, default: 20, 0 is unlimited
### 15 Listen on multiple ports
"tcp / http / socks / sps" supports listen on multiple ports and range ports.
Under normal circumstances, it is sufficient to listen on one port, but if you need to listen on multiple ports, the -p parameter is supported.
The format is: `-p 0.0.0.0:80,0.0.0.0:443,.0.0.0.0:8000-9000,:5000-6000`, more The bindings can be separated by commas.
We can also specify the black and white list file of the website domain name, one domain name per line, the matching rule is the rightmost match, for example: baidu.com, the match is *.*.baidu.com, the blacklist domain name goes directly to the upstream agent, whitelist The domain name does not go to the upstream agent.
Then set your windos system, the proxy that needs to go through the proxy Internet program is http mode, the address is: 127.0.0.1, the port is: 8080, the program can access the Internet through vps through the encrypted channel.
In addition, the http(s) proxy also integrates external HTTP API authentication. We can specify an http url interface address with the --auth-url parameter.
Then when there is a user connection, the proxy will request the url in GET mode, and bring the following four parameters. If the HTTP status code 204 is returned, the authentication is successful.
Local_ip: IP of the server accessed by the user, for example: 3.3.3.3
Target: URL accessed by the user, for example: http://demo.com:80/1.html or https://www.baidu.com:80
If there is no -a or -F or --auth-url parameter, the Basic authentication is turned off.
### 1.6. HTTP proxy traffic is forced to go to the upper HTTP proxy
By default, the proxy will intelligently determine whether a website domain name is inaccessible. If it is not accessible, it will go to the upper level HTTP proxy. With --always, all HTTP proxy traffic can be forced to go to the upper HTTP proxy.
Description: The principle of ssh transfer is to use the forwarding function of ssh, that is, after you connect to ssh, you can access the target address through ssh proxy.
Suppose there is: vps
- IP is 2.2.2.2, ssh port is 22, ssh username is: user, ssh user password is: demo
Then access the local port 8080 is to access the proxy port 38080 on the VPS, the data is transmitted through the kcp protocol, note that the kcp is the udp protocol, so the firewall needs to release the 380p udp protocol.
The proxy not only supports the proxy setting in other software, but also provides proxy services for other software. It also supports directly parsing the requested website domain name to the proxy listening ip, and then the proxy listens to the 80 and 443 ports, then the proxy will automatically You proxy access to the HTTP(S) website you need to access.
How to use:
On the "last level proxy proxy" machine, because the proxy is to be disguised as all websites, the default HTTP port of the website is 80, HTTPS is 443, and the proxy can listen to ports 80 and 443. Parameters -p multiple addresses with commas segmentation.
`proxy http -t tcp -p :80,:443`
This command starts a proxy agent on the machine, and listens to ports 80 and 443 at the same time. It can be used as a normal proxy, or directly resolve the domain name that needs to be proxyed to the IP of this machine.
If there is a upstream agent, then refer to the above tutorial to set the upstream, the use is exactly the same.
The DNS resolution result of the server where the proxy is located cannot be affected by the custom resolution, otherwise it will be infinite loop. The proxy proxy should specify the `--dns 8.8.8.8` parameter.
### 1.10 HTTP(S) Transparent Proxy
This mode needs to have a certain network foundation. If the related concepts are not understood, please search for it yourself.
Assuming the proxy is now running on the router, the startup command is as follows:
- Clear the entire chain iptables -F Chain names such as iptables -t nat -F PROXY
- Delete the specified user-defined chain iptables -X chain name such as iptables -t nat -X PROXY
- Remove rules from the selected chain iptables -D chain name Rule details such as iptables -t nat -D PROXY -d 223.223.192.0/255.255.240.0 -j RETURN
### 1.11 Custom DNS
--dns-address and --dns-ttl parameters, used to specify the dns (--dns-address) used by the proxy to access the domain name.
And the analysis result cache time (--dns-ttl) seconds, to avoid system dns interference to the proxy, in addition to the cache function can also reduce the dns resolution time to improve access speed.
The proxy's http(s) proxy can encrypt tcp data via tls standard encryption and kcp protocol on top of tcp, in addition to support customization after tls and kcp.
Encryption, that is to say, custom encryption and tls|kcp can be used in combination. The internal use of AES256 encryption, you only need to define a password when you use it.
Encryption is divided into two parts, one is whether the local (-z) encryption and decryption, and the other is whether the transmission with the upstream (-Z) is encrypted or decrypted.
Custom encryption requires both ends to be proxy. The following two levels and three levels are used as examples:
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
### 1.13 Compressed transmission
The proxy http(s) proxy can encrypt tcp data through tls standard encryption and kcp protocol on top of tcp, and can also compress data before custom encryption.
That is to say, compression and custom encryption and tls|kcp can be used in combination. Compression is divided into two parts, one part is local (-m) compression transmission.
Part of it is compressed with the upstream (-M) transmission.
Compression requires both sides to be proxy. Compression also protects (encrypted) data to a certain extent. The following uses Level 2 and Level 3 as examples:
The speed limit is 100K, which can be specified by the `-l` parameter, for example: 100K 2000K 1M . 0 means no limit.
`proxy http -t tcp -p 2.2.2.2:33080 -l 100K`
### 1.16 Specifying Outgoing IP
The `--bind-listen` parameter can be used to open the client connection with the portal IP, and use the portal IP as the outgoing IP to access the target website. If the incorrect IP is bound, the proxy will not work. At this point, the proxy will try to bind the target without binding the IP, and the log will prompt.
Although the above `--bind-listen` parameter can specify the outgoing IP, the `entry IP` and the `outgoing IP` cannot be referenced artificially. If you want the ingress IP and the egress IP to be different, you can use the `--bind-ip` parameter, format: `IP:port`, for example: `1.1.1.1:8080`, `[2000:0:0:0:0 :0:0:1]:8080`. For multiple binding requirements, the `--bind-ip` parameter can be repeated.
For example, this machine has IP `5.5.5.5`, `6.6.6.6`, and monitors two ports `8888` and `7777`, the command is as follows:
Then the client access port `7777`, the outgoing IP is `5.5.5.5`, access port `8888`, the outgoing IP is `6.6.6.6`, if both `--bind-ip` and `--bind- are set at the same time listen`,`--bind-ip` has higher priority.
In addition, the `IP` part of the `--bind-ip` parameter supports specifying the `network interface name`, `wildcards`, and more than one can be specified. The detailed description is as follows:
- Specify the network interface name, such as: `--bind-ip eth0:7777`, and then the client accesses the `7777` port, and the egress IP is the IP of the eth0 network interface.
- The network interface name supports wildcards, such as: `--bind-ip eth0.*:7777`, then the client accesses the port `7777`, and the egress IP is randomly selected from the IP of the network interface starting with `eth0.`.
- IP supports wildcards, such as: `--bind-ip 192.168.?.*:777`, then the client accesses the `7777` port, the outgoing IP is all the IPs of the machine, and matches the IP of `192.168.?.*` A randomly selected one.
- It can also be several combinations of network interface name and IP, and several selective divisions using half-width, such as: `-bind-ip pppoe??,192.168.?.*:7777`, and then the client accesses the `7777` port , The outgoing IP is the machine's network interface name matching `pppoe??`
- If the IP of the network interface changes, it will take effect in real time.
- You can use the `--bind-refresh` parameter to specify the interval to refresh the local network interface information, the default is `5`, the unit is second.
If the number of local listening ports is greater than 1, the corresponding upper port corresponding to the local port will be connected, and the port in `-P` will be ignored.
If you need a connection from all ports, connect to the upper specified port, you can add the parameter `--lock-port`.
Then the connection of the `33080` port will connect to the `33080` port of 192.168.22.33, and the other ports are similar. The local and upper ports are the same. At this time, the port in the parameter `-P` uses `0`.
If you want to connect the ports of `33080`, `33081`, etc. to the `22` port of 192.168.22.33, you can add the parameter `--lock-port`.
Sometimes the network where the proxy is located cannot directly access the external network. You need to use an https or socks5 proxy to access the Internet. Then this time
The -J parameter can help you to connect the proxy to the peer-P through the https or socks5 proxy when mapping the proxy tcp port, mapping the external port to the local.
The -J parameter format is as follows:
Https proxy writing:
The proxy needs authentication, username: username password: password
Https://username:password@host:port
Agent does not require authentication
Https://host:port
Socks5 proxy writing:
The proxy needs authentication, username: username password: password
Socks5://username:password@host:port
Agent does not require authentication
Socks5://host:port
Host: the IP or domain name of the proxy
Port: the port of the proxy
### 2.7 Specify Outgoing IP
When the TCP proxy is a superior type (parameter: -T) is tcp, it supports the specified exit IP. Using the `--bind-listen` parameter, you can open the client to connect with the portal IP, and use the portal IP as the outgoing IP to access the target website. If an incorrect IP is bound, the proxy will not work, the proxy will try to bind the target without binding the IP, and the log will prompt.
Although the above `--bind-listen` parameter can specify the outgoing IP, the `entry IP` and the ` outgoing IP` cannot be referenced artificially. If you want the ingress IP to be different from the egress IP, you can use the `--bind-ip` parameter, format: `IP:port`, for example: `1.1.1.1:8080`
, `[2000:0:0:0:0:0:0:1]:8080`. For multiple binding requirements, you can repeat the `--bind-ip` parameter identification.
For example, this machine has IP `5.5.5.5`, `6.6.6.6`, and monitors two ports `8888` and `7777`, the command is as follows:
Then the client access port `7777`, the outgoing IP is `5.5.5.5`, access port `8888`, the outgoing IP is `6.6.6.6`, if both `--bind-ip` and `--bind- are set at the same time listen`,`--bind-ip` has higher priority.
In addition, the `IP` part of the `--bind-ip` parameter supports specifying the `network interface name`, `wildcards`, and more than one can be specified. The detailed description is as follows:
- Specify the network interface name, such as: `--bind-ip eth0:7777`, then the client accesses the `7777` port, and the egress IP is the IP of the eth0 network interface.
- The network interface name supports wildcards, for example: `--bind-ip eth0.*:7777`, then the client accesses the `7777` port, and the egress IP is a randomly selected one of the network interface IPs starting with `eth0.`.
- IP supports wildcards, such as: `--bind-ip 192.168.?.*:7777`, then the client accesses the `7777` port, and the exit IP is all the IPs of the machine, matching the IP of `192.168.?.*` A randomly selected one.
- It can also be multiple combinations of network interface name and IP, separated by half-width commas, such as: `--bind-ip pppoe??,192.168.?.*:7777`, then the client accesses the port `7777`, The outgoing IP is the machine's network interface name matching `pppoe??`
- If the IP of the network interface changes, it will take effect in real time.
- You can use the `--bind-refresh` parameter to specify the interval to refresh the local network interface information, the default is `5`, the unit is second.
`--c` controls whether to compress transmission between local and client, default false;` --C` controls whether to compress transmission between local and upstream, default false.
If the number of local listening ports is greater than 1, the corresponding upper port corresponding to the local port will be connected, and the port in `-P` will be ignored.
If you need a connection from all ports, connect to the upper specified port, you can add the parameter `--lock-port`.
Then the connection of the `33080` port will connect to the `33080` port of 192.168.22.33, and the other ports are similar. The local and upper ports are the same. At this time, the port in the parameter `-P` uses `0`.
If you want to connect the ports of `33080`, `33081`, etc. to the `2222` port of 192.168.22.33, you can add the parameter `--lock-port`.
Then access the local 5353 port is to access the 8.8.8.8 port 53 through VPS_01 through the encrypted TCP tunnel.
### 3.6 Specify Outgoing IP
When the UDP upstream proxies (parameter: -T) is udp, it supports the specified outgoing IP. Using the `--bind-listen` parameter, you can open the client to connect with the server IP, and use the server IP as the outgoing IP to access the target. If an incorrect IP is bound, the proxy will not work.
Intranet penetration, divided into two versions, "multi-link version" and "multiplexed version", generally like a web service, this service is not a long-term connection, it is recommended to use "multi-link version", if it is to keep long The time connection suggests using a "multiplexed version."
1. Multi-link version, the corresponding sub-command is tserver, tclient, tbridge.
1. Multiplexed version, the corresponding subcommand is server, client, bridge.
1. The parameters of the multi-link version and the multiplex version are exactly the same.
1. The multiplexed version of the server, client can open the compressed transmission, the parameter is --c.
1. server, client either open compression, or not open, can not open only one.
The following tutorial uses the "multiplexed version" as an example to illustrate how to use it.
The intranet penetration consists of three parts: client, server, and bridge; client and server actively connect to the bridge for bridging.
### 4.2 TCP common usage
Background:
- Company Machine A provides web service port 80
- There is a VPS, public network IP: 22.22.22.22
Demand:
At home, you can access the port 80 of company machine A by accessing port 28080 of the VPS.
If multiple clients are connected to the same bridge at the same time, you need to specify a different key, which can be set by the --k parameter, and --k can be any unique string.
Just be the only one on the same bridge.
When the server is connected to the bridge, if there are multiple clients connecting to the same bridge at the same time, you need to use the --k parameter to select the client.
Expose multiple ports by repeating the -r parameter. The format of -r is: "local IP: local port @clientHOST:client port".
### 4.8.server and client connect bridge through proxy
Sometimes the network where the server or client is located cannot directly access the external network. You need to use an https or socks5 proxy to access the Internet. Then this time
The -J parameter can help you to connect the server or client to the bridge via https or socks5.
The -J parameter format is as follows:
Https proxy writing:
The proxy needs authentication, username: username password: password
Https://username:password@host:port
Agent does not require authentication
Https://host:port
Socks5 proxy writing:
The proxy needs authentication, username: username password: password
Usually the HTTP request client will use the server's ip and port to set the HOST field, but it is not the same as the expected backend actual HOST, which causes tcp to be passed.However, the backend relies on the HOST field to locate the virtual host and it will not work. Now use the `--http-host` parameter to force the HOST field value of the http header to be the actual value of the backend.Domain names and ports can be easily solved. After using the `--http-host` parameter, two headers will be added to the header of each HTTP request. The `X-Forwarded-For` and `X-Real-IP` values are the client IP, so the backend http service can easily obtain the real IP address of the client.
The format of the `server`-http-host parameter is as follows:
`--http-host www.test.com:80@2200`, if the server listens to multiple ports, just repeat the `--http-host` parameter to set the HOST for each port.
Example:
For example, the client local nginx, 127.0.0.1:80 provides a web service, which is bound to a domain name `local.com`.
Then the server startup parameters can be as follows:
`proxy server -P :30000 -r :2500@127.0.0.1:80 --http-host local.com@2500`
Explanation:
`-r :2500@127.0.0.1:80` and `--http-host local.com:80@2500` The 2500 port is the port that the server listens locally.
When the http protocol is used to request the ip:2500 port of the server, the header HOST field of http will be set to `local.com`.
### 4.10 About traffic statistics
If you start a server docking peer separately, it is the proxy-admin control panel. You need to create a new mapping in the upper-level control panel to obtain the ID of the mapping rule.
Then start the server and add the parameter --server-id=the ID of the mapping rule to count the traffic.
### 4.11 About p2p
Intranet penetration support When the server and client network conditions are met, the server and client are directly connected through p2p. The opening method is:
When starting the bridge, server, client, add the `--p2p` parameter. The server's -r parameter can be used to enable p2p (ptcp and pudp) for the port.
If the p2p hole fails between the server and the client, the bridge transfer data is automatically switched.
### 4.12 Client key whitelist
The intranet penetrating bridge can set the client key whitelist. The parameter is --client-keys. The format can be:
a. File name, file content One client key can only contain the alphanumeric underscore, which is the value of the client startup parameter --k. Only the client key can connect to the whitelist client. The line starting with # is a comment.
b. The base64 encoding at the beginning of "base64://" is the content of the file described in a above, for example: base64://ajfpoajsdfa=
c. "str://" multiple keywords separated by a comma at the beginning, such as: str://default,company,school
The default is empty, allowing all keys.
### 4.13 Network NAT Type Judgment
Senat type judgment, easy to check whether the network supports p2p, you can execute: `proxy tools -a nattype`
***The udp function of socks5 is turned off by default, and can be turned on by `--udp`. The default is a random port for handshake, and performance can be improved by fixing a port.
Set by parameter `--udp-port 0`, `0` represents a free port is randomly selected, or you can manually specify a specific port. ***
### 5.1. Ordinary SOCKS5 Agent
`proxy socks -t tcp -p "0.0.0.0:38080"`
Listen port argument `-p` can be:
```text
-p ":8081" listen on 8081
-p ":8081,:8082" listen on 8081 and 8082
-p ":8081,:8082,:9000-9999" listen on 8081 and 8082 and 9000 and 9001 to 9999, 1002 total ports
We can also specify the black and white list file of the website domain name, one domain name and one domain name, the matching rule is the rightmost match, for example: baidu.com, the match is *.*.baidu.com, the blacklist domain name domain name goes directly to the upstream agent, white The domain name of the list does not go to the upstream agent; if the domain name is in the blacklist and in the whitelist, the blacklist works.
Then set your windos system, the proxy that needs to go through the proxy Internet program is the socks5 mode, the address is: 127.0.0.1, the port is: 8080, the program can access the Internet through vps through the encrypted channel.
### 5.5. SOCKS proxy traffic is forced to go to the upper level SOCKS proxy
By default, the proxy will intelligently determine whether a website domain name is inaccessible. If it is not accessible, it will go to the upstream SOCKS proxy. With --always, all SOCKS proxy traffic can be forced to go to the upper SOCKS proxy.
Description: The principle of ssh transfer is to use the forwarding function of ssh, that is, after you connect to ssh, you can access the target address through ssh proxy.
Suppose there is: vps
- IP is 2.2.2.2, ssh port is 22, ssh username is: user, ssh user password is: demo
Then access the local port 28080 is to access the target address through the VPS.
### 5.7. Certification
For the socks5 proxy protocol, we can perform username and password authentication. The authenticated username and password can be specified on the command line.
`proxy socks -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2"`
For multiple users, repeat the -a parameter.
It can also be placed in a file in the format of a "username:password" and then specified with -F.
`proxy socks -t tcp -p ":33080" -F auth-file.txt`
In addition, the socks5 agent also integrates external HTTP API authentication. We can specify an http url interface address with the --auth-url parameter.
Then when there is a user connection, the proxy will request the url in GET mode, with the following three parameters. If the HTTP status code 204 is returned, the authentication is successful.
Then access the local port 8080 is to access the proxy port 38080 on the VPS, the data is transmitted through the kcp protocol.
### 5.9. Custom DNS
--dns-address and --dns-ttl parameters, used to specify the dns (--dns-address) used by the proxy to access the domain name.
And the analysis result cache time (--dns-ttl) seconds, to avoid system dns interference to the proxy, in addition to the cache function can also reduce the dns resolution time to improve access speed.
The proxy's socks proxy can encrypt tcp data through tls standard encryption and kcp protocol on top of tcp. In addition, it supports custom encryption after tls and kcp, which means that custom encryption and tls|kcp can be used together. The internal use of AES256 encryption, you only need to define a password when you use it.
Encryption is divided into two parts, one is whether the local (-z) encryption and decryption, and the other is whether the transmission with the upstream (-Z) is encrypted or decrypted.
Custom encryption requires both sides to be proxy.
The following two levels, three levels for example:
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
### 5.11 Compressed transmission
The proxy's socks proxy can encrypt tcp data through custom encryption and tls standard encryption and kcp protocol on top of tcp. It can also be used before custom encryption.
Compress the data, that is, the compression function and the custom encryption and tls|kcp can be used in combination, and the compression is divided into two parts.
Part of it is local (-m) compression transmission, and part is whether the transmission with the upstream (-M) is compressed.
Compression requires both sides to be proxy, and compression also protects (encrypts) data to some extent.
The following two levels, three levels for example:
The speed limit is 100K, which can be specified by the `-l` parameter, for example: 100K 2000K 1M . 0 means no limit.
`proxy socks -t tcp -p 2.2.2.2:33080 -l 100K`
### 5.14 Specifying Outgoing IP
The `--bind-listen` parameter can be used to open the client connection with the portal IP, and use the portal IP as the outgoing IP to access the target website. If the ingress IP is an intranet IP, the egress IP does not use the ingress IP.
Although the above `--bind-listen` parameter can specify the outgoing IP, the `entry IP` and ` outgoing IP` cannot be interfered by humans. If you want the ingress IP to be different from the egress IP, you can use the `--bind-ip` parameter, format: `IP:port`, for example: `1.1.1.1:8080`
, `[2000:0:0:0:0:0:0:1]:8080`. For multiple binding requirements, you can repeat the `--bind-ip` parameter.
For example, the machine has IP `5.5.5.5`, `6.6.6.6`, and monitors two ports `8888` and `7777`, the command is as follows:
Then the client access port `7777`, the outgoing IP is `5.5.5.5`, access port `8888`, the outgoing IP is `6.6.6.6`, if both `--bind-ip` and `--bind- are set at the same time listen`,`--bind-ip` has higher priority.
In addition, the `IP` part of the `--bind-ip` parameter supports specifying the `network interface name`, `wildcards`, and more than one. The details are as follows:
- Specify the network interface name, such as: `--bind-ip eth0:7777`, then the client accesses the `7777` port, and the egress IP is the IP of the eth0 network interface.
- The network interface name supports wildcards, for example: `--bind-ip eth0.*:7777`, then the client accesses the `7777` port, and the egress IP is a randomly selected one of the network interface IPs starting with `eth0.`.
- IP supports wildcards, such as: `--bind-ip 192.168.?.*:7777`, then the client accesses the `7777` port, and the exit IP is all the IPs of the machine, matching the IP of `192.168.?.*` A randomly selected one.
- It can also be multiple combinations of network interface name and IP, separated by half-width commas, such as: `--bind-ip pppoe??,192.168.?.*:7777`, then the client accesses the port `7777`, The outgoing IP is the machine's network interface name matching `pppoe??`
- If the IP of the network interface changes, it will take effect in real time.
- You can use the `--bind-refresh` parameter to specify the interval to refresh the local network interface information, the default is `5`, the unit is second.
`--intelligent=direct`, the targets in the blocked are not directly connected.
`--intelligent=parent`, the target that is not in the direct is going to the higher level.
`--intelligent=intelligent`, blocked and direct have no targets, intelligently determine whether to use the upstream access target.
### 5.18 Fixed UDP PORT
By default, the port number of the UDP function of socks5, the proxy is installed in the `rfc1982 draft` request, which is randomly specified during the protocol handshake process and does not need to be specified in advance.
However, in some cases, you need to fix the UDP function port. You can use the parameter `--udp-port port number` to fix the port number of the UDP function. For example:
The proxy protocol conversion uses the sps subcommand. The sps itself does not provide the proxy function. It only accepts the proxy request to "convert and forward" to the existing http(s) proxy or the socks5 proxy or ss proxy; the sps can put the existing http(s) proxy or socks5 proxy or ss proxy is converted to a port that supports both http(s) and socks5 and ss proxies, and the http(s) proxy supports forward proxy and reverse proxy (SNI), converted SOCKS5 proxy, UDP function is still supported when the upper level is SOCKS5 or SS; in addition, for the existing http(s) proxy or socks5 proxy, three modes of tls, tcp, and kcp are supported, and chain connection is supported, that is, multiple sps node levels can be supported. The connection builds an encrypted channel.
-p ":8081,:8082,:9000-9999" listen on 8081 and 8082 and 9000 and 9001 to 9999, 1002 total ports
```
The udp function of ss is turned off by default and can be turned on by `--ssudp`. The udp function of socks5 is turned off by default and can be turned on by `--udp`, The default is a random port for handshake, and performance can be improved by fixing a port.
Set by parameter `--udp-port 0`, `0` represents a free port is randomly selected, or you can manually specify a specific port.
### 6.2 HTTP(S) to HTTP(S)+SOCKS5+SS
Suppose there is already a normal http(s) proxy: 127.0.0.1:8080. Now we turn it into a common proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, ss encryption: Aes-192-cfb, ss password: pass.
Suppose there is already a tls http(s) proxy: 127.0.0.1:8080. Now we turn it into a normal proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, and tls requires a certificate file. , ss encryption: aes-192-cfb, ss password: pass.
Suppose there is already a kcp http(s) proxy (password is: demo123): 127.0.0.1:8080, now we turn it into a normal proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, ss encryption: aes-192-cfb, ss password: pass.
Suppose there is already a normal socks5 proxy: 127.0.0.1:8080, now we turn it into a common proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, ss encryption: aes-192 -cfb, ss password: pass.
Suppose there is already a tls socks5 proxy: 127.0.0.1:8080, now we turn it into a common proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, tls requires certificate file, ss encryption Mode: aes-192-cfb, ss password: pass.
Suppose there is already a kcp socks5 proxy (password: demo123): 127.0.0.1:8080, now we turn it into a common proxy that supports both http(s) and socks5 and ss. The converted local port is 18080, ss Encryption method: aes-192-cfb, ss password: pass.
SPS upstream and local support ss protocol, the upstream can be SPS or standard ss service.
SPS locally provides HTTP(S)\SOCKS5\SPS three defaults. When the upstream is SOCKS5, the converted SOCKS5 and SS support UDP.
Suppose there is already a normal SS or SPS proxy (ss is enabled, encryption: aes-256-cfb, password: demo): 127.0.0.1:8080, now we turn it to support both http(s) and socks5 and The ordinary proxy of ss, the converted local port is 18080, the converted ss encryption mode: aes-192-cfb, ss password: pass.
The above mentioned multiple sps nodes can be connected to build encrypted channels in a hierarchical connection, assuming the following vps and the home PC.
Vps01:2.2.2.2
Vps02:3.3.3.3
Now we want to use pc and vps01 and vps02 to build an encrypted channel. This example uses tls encryption or kcp. Accessing local 18080 port on the PC is to access the local 8080 port of vps01.
First on vps01 (2.2.2.2) we run a locally accessible http(s) proxy and execute:
`proxy http -t tcp -p 127.0.0.1:8080`
Then run a sps node on vps01 (2.2.2.2) and execute:
`protocol://` is the protocol type, possible types and contains the following:
```text
Http is equivalent to -S http -T tcp
Https is equivalent to -S http -T tls --parent-tls-single , which is http(s) proxy over TLS
Https2 is equivalent to -S http -T tls
Socks5 is equivalent to -S socks -T tcp
Socks5s is equivalent to -S socks -T tls --parent-tls-single , which is socks over TLS
Socks5s2 is equivalent to -S socks -T tls
Ss is equivalent to -S ss -T tcp
Httpws is equivalent to -S http -T ws
Httpwss is equivalent to -S http -T wss
Socks5ws is equivalent to -S socks -T ws
Socks5wss is equivalent to -S socks -T wss
```
`a:b` is the username and password of the proxy authentication. If it is ss, `a` is the encryption method, `b` is the password, and no username password can be left blank, for example: `http://2.2.2.2:33080` If the username and password are protected, special symbols can be encoded using urlencode.
`2.2.2.2:33080` is the upstream address, the format is: `IP (or domain name): port `, if the underlying is ws/wss protocol can also bring the path, such as: `2.2.2.2: 33080/ws`;
You can also set the `encryption method` and `password` of `ws\wss` by appending the query parameters `m` and `k`, for example: `2.2.2.2:33080/ws?m=aes-192-cfb&k=password`
`#1` When multiple upper-level load balancing is a weighting strategy, the weights are rarely used.
### 6.8 Custom Encryption
The proxy sps proxy can encrypt tcp data through tls standard encryption and kcp protocol on top of tcp, in addition to support after tls and kcp
Custom encryption, that is, custom encryption and tls|kcp can be used in combination, internally using AES256 encryption, only need to define it when using
A password can be used, the encryption is divided into two parts, one part is whether the local (-z) encryption and decryption, and the part is the encryption and decryption with the upstream (-Z) transmission.
Custom encryption requires both sides to be proxy.
The following two levels, three levels for example:
Suppose there is already an http(s) proxy: `6.6.6.6:6666`
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream.
### 6.9 Compressed transmission
The proxy sps proxy can encrypt tcp data through custom encryption and tls standard encryption and kcp protocol on top of tcp. It can also be used before custom encryption.
Compress the data, that is, the compression function and the custom encryption and tls|kcp can be used in combination, and the compression is divided into two parts.
Part of it is local (-m) compression transmission, and part is whether the transmission with the upstream (-M) is compressed.
Compression requires both sides to be proxy, and compression also protects (encrypts) data to some extent.
The following two levels, three levels for example:
It can be specified by the `-l` parameter, for example: 100K 2000K 1M . 0 means no limit.
### 6.12 Specifying Outgoing IP
The `--bind-listen` parameter can be used to open the client connection with the portal IP, and use the portal IP as the outgoing IP to access the target website. If the ingress IP is an intranet IP, the egress IP does not use the ingress IP.
Although the above `--bind-listen` parameter can specify the outgoing IP, the `entry IP` and ` outgoing IP` cannot be interfered by humans. If you want the ingress IP to be different from the egress IP, you can use the `--bind-ip` parameter, format: `IP:port`, for example: `1.1.1.1:8080`
, `[2000:0:0:0:0:0:0:1]:8080`. For multiple binding requirements, you can repeat the `--bind-ip` parameter.
For example, the machine has IP `5.5.5.5`, `6.6.6.6`, and monitors two ports `8888` and `7777`, the command is as follows:
Then the client access port `7777`, the outgoing IP is `5.5.5.5`, access port `8888`, the outgoing IP is `6.6.6.6`, if both `--bind-ip` and `--bind- are set at the same time listen`,`--bind-ip` has higher priority.
In addition, the `IP` part of the `--bind-ip` parameter supports specifying the `network interface name`, `wildcards`, and more than one. The details are as follows:
- Specify the network interface name, such as: `--bind-ip eth0:7777`, then the client accesses the `7777` port, and the egress IP is the IP of the eth0 network interface.
- The network interface name supports wildcards, for example: `--bind-ip eth0.*:7777`, then the client accesses the `7777` port, and the egress IP is a randomly selected one of the network interface IPs starting with `eth0.`.
- IP supports wildcards, such as: `--bind-ip 192.168.?.*:7777`, then the client accesses the `7777` port, and the exit IP is all the IPs of the machine, matching the IP of `192.168.?.*` A randomly selected one.
- It can also be multiple combinations of network interface name and IP, separated by half-width commas, such as: `--bind-ip pppoe??,192.168.?.*:7777`, then the client accesses the port `7777`, The outgoing IP is the machine's network interface name matching `pppoe??`
- If the IP of the network interface changes, it will take effect in real time.
- You can use the `--bind-refresh` parameter to specify the interval to refresh the local network interface information, the default is `5`, the unit is second.
By default, the -C, -K parameter is the path to the crt certificate and the key file.
If it is the beginning of base64://, then the latter data is considered to be base64 encoded and will be used after decoding.
### 6.14 Independent Service
A sps port can complete the full-featured proxy `http\socks\ss` function.
The following command is to open the http(s)\ss\socks service with one click, and enable the udp of socks5 and the udp of ss at the same time.
`proxy sps -p: 33080 --ssudp --udp --udp-port 0`
### 6.15 Target Redirection
The https(s)\socks5\ss proxy function provided by the sps function, the client connects to the specified "target" through the sps proxy. This "target" is generally a website or an arbitrary tcp address.
The website "target" is generally foo.com: 80, foo.com: 443, sps supports the use of the --rewrite parameter to specify a "target" redirection rule file, redirect the target, the client is non-perceived,
For example, if you redirect to "target": demo.com:80 to 192.168.0.12:80, then the client visits the website demo.com, in fact, the website service provided by 192.168.0.12.
Example of a "target" redirection rule file:
```text
# example
Www.a.com:80 10.0.0.2:8080
**.b.com:80 10.0.0.2:80
192.168.0.11:80 10.0.0.2:8080
```
When sps is an independent service, an additional local socks5 service will be opened to occupy a random port. Now the parameter `--self-port` can be manually specified when needed. The default is 0 to use random.
### 6.16 Fixed UDP PORT
By default, the port number of the UDP function of ss's socks5 is specified by the `rfc1982 draft`. It is randomly specified during the protocol handshake process and does not need to be specified in advance.
However, in some cases, you need to fix the UDP function port. You can fix the port number of the UDP function by the parameter `--udp-port port_number`, for example:
It should be noted that the ss function of sps also has UDP function, and the UDP port of ss is the same as the tcp port, so avoid the conflict between the UDP port of socks5 and the UDP port of ss.
To specify a port that is different from the tcp port.
### 6.17 iptables 透明代理
The sps mode supports the iptables transparent forwarding support of the Linux system, which is commonly referred to as the iptables transparent proxy. If a iptables transparent proxy is performed on the gateway device, the device that is connected through the gateway can realize a non-aware proxy.
- Clear the entire chain iptables -F chain name such as iptables -t nat -F PROXY
- Delete the specified user-defined chain iptables -X chain name e.g. iptables -t nat -X PROXY
- Delete rule from selected chain iptables -D chain name rule details e.g. iptables -t nat -D PROXY -d 223.223.192.0/255.255.240.0 -j RETURN
### 6.18 Help
`proxy help sps`
## 7.KCP Configuration
### 7.1 Configuration Introduction
Many functions of the proxy support the kcp protocol. Any function that uses the kcp protocol supports the configuration parameters described here.
Therefore, the KCP configuration parameters are introduced here.
### 7.2 Detailed configuration
There are a total of 17 KCP configuration parameters, you can not set them, they have default values, if for the best effect,
You need to configure the parameters according to your own network conditions. Because the kcp configuration is complex, it requires a certain network basics.
If you want to get more detailed configuration and explanation of kcp parameters, please search for yourself. The command line name for each parameter, along with the default values and simple function descriptions are as follows:
DNS is known as the service provided by UDP port 53, but with the development of the network, some well-known DNS servers also support TCP mode dns query, such as Google's 8.8.8.8, the DNS anti-pollution server principle of the proxy is to start a proxy DNS proxy locally. Server, which uses TCP to perform dns query through the upstream agent. If it communicates with the upstream agent, it can perform secure and pollution-free DNS resolution. It also supports independent services, concurrent parsing, and enhanced enhanced hosts file function to support flexible concurrent parsing and forwarding.
Dns resolution order:
1. Use the parameter --hosts to parse.
2. If the domain name to be resolved is not found in 1, it is parsed using the parameter --forward rule.
3. The domain name to be resolved is not found in 1 and 2, and the default --default parsing is used. The default default behavior parameter values are three: proxy, direct, and system.
The three parameter values are explained as follows:
Proxy: The domain name is resolved by the dns server specified by the -q parameter.
Direct: Connect to the dns server specified by the -q parameter to resolve the domain name through the local network.
System: resolves the domain name through the system dns.
The host file format specified by the --hosts parameter is the same as the system hosts file, and the domain name supports wildcards. You can refer to the hosts file.
The parsing forwarding rule file specified by the --forward parameter can be referenced to the resolve.rules file. The domain name supports wildcards. It supports multiple dns servers for each domain name to be parsed concurrently. Whoever resolves the fastest resolution will use the resolution result.
The -q parameter can specify multiple remote dns servers to perform concurrent parsing. Whoever resolves the fastest parsing success, the default is: 1.1.1.1, 8.8.8.8, 9.9.9.9, multiple comma-separated,
- Dynamic upstream, can dynamically obtain its upstream from the API according to the user or client IP, and support http(s)/socks5/ss upstream.
- Authenticate every connection, regardless of whether client authentication is required.
- Cache authentication results, time can be set to reduce API pressure.
#### Specific use
The proxy's http(s)/socks5/sps proxy API function is controlled by three parameters: `--auth-url` and `--auth-nouser` and `--auth-cache`.
The parameter `--auth-url` is the HTTP API interface address. When the client connects, the proxy will request the url in GET mode, with the following parameters. If the HTTP status code 204 is returned, the authentication is successful. In other cases, the authentication fails.
`user and pass` When the proxy turns on authentication, here is the username and password provided by the client.
`client_addr` The address used by the client to access the proxy, format IP: port.
`local_addr` The proxy address accessed by the client, format IP: port.
`service` Proxy type, divided into: http, socks.
Whether the `sps` proxy is provided by sps, 1: yes, 0: no.
`target` The target to be accessed by the client. If it is an http(s) proxy, the target is the specific url accessed; if it is a socks5 proxy, the target is empty.
#### Example
Suppose --auth-url http://127.0.0.1:333/auth.php points to a php interface address.
1. By default, `--auth-url` is required to provide the user name and password. If you do not need the client to provide the username and password, and authenticate, you can add `--auth-nouser`. The visit will still access the authentication address `--auth-url` for authentication. Only the $user authentication username and the $pass authentication password received in the php interface are empty when client didn't send username and password.
2. Connection limit priority: User authentication file limit - "File ip.limit limit -" API user limit - "API IP limit -" command line global connection limit.
3. Rate Limit Priority: User Authentication File Rate Limit - "File ip.limit Rate Limit -" API User Rate Limit - "API IP Rate Limit - "Command Line Global Rate Limit.
3. The upstream obtains the priority: the upstream of the user authentication file - the file ip.limit upstream-"API upstream-" command line specifies the upstream.
4.`--auth-cache` authentication cache, cache the authentication result for a certain period of time, improve performance, reduce the pressure on the authentication interface, --auth-cache unit seconds, default 0, set 0 to close the cache.
#### upstream detailed description
1. When the parameter `sps` is 0.
When the service is http, upstream only supports http(s) proxy, and does not support authentication. If authentication is required, it can be replaced by sps. Format:
Explanation: `http://`,`socks5://` is fixed, `127.0.0.1:3100` is the address of the upstream
2. When `sps` is 1.
Upstream supports socks5, http(s) proxy, support authentication, format: `protocol://a:b@2.2.2.2:33080?argk=argv`, please refer to SPS chapter for details, **multiple upstreams** , the description of the `-P` parameter.
3. Parameters, `?` followed by `argk=argv` are parameters: parameter name = parameter value, multiple parameters are connected with `&`.
All the supported parameters are as follows, and the meaning of the command line with the same name is the same.
1. parent-type : upper-level transport type, support tcp, tls, ws, wss
2. parent-ws-method: The encryption method of the upper-level ws transmission type, the supported value is the same as the value range supported by the command line.
3. parent-ws-password: The upper-level ws transmission type encryption password, the alphanumeric password
4. parent-tls-single : Whether the upper-level tls transport type is a one-way tls, which can be: true | false
5. timeout : timeout for establishing tcp connection, number, in milliseconds
6. ca : The base64-encoded string of the upper-level tls transport type ca certificate file.
7. cert : The base64 encoded string of the higher level tls transport type certificate file.
8. key : The base64 encoded string of the higher-level tls transport type certificate key file.
9. luminati:if upstram is luminati proxies，value can be: true or false。
The proxy's http (s) / socks5 / sps / tcp / udp proxy function supports traffic reporting. You can set an http interface address through the parameter `--traffic-url`.
The proxy will report the traffic used for this connection to this address.Specifically, the proxy sends an HTTP to GET request to the HTTP URL address set by `--traffic-url`.
There are two reporting modes, which can be specified by the `--traffic-mode` parameter. It can be reported in the normal mode or in the fast mode.
1. Report in `normal` normal mode
When the connection is released, the proxy will report the traffic used for this connection to this `--traffic-url` address.
2. Report in `fast` mode
For each connection that has been established, the proxy will `timely` report the traffic generated by this connection to this` --traffic-url` address.
`Timing` defaults to 5 seconds, and you can modify` Timing` to the appropriate number of seconds via the parameter `--traffic-interval`.
The traffic reporting function combined with the above API authentication function can control the user's traffic usage in real time. The traffic is reported to the interface. The interface writes the traffic data to the database, and then the authentication API queries the database to determine the traffic usage and determine whether the user can be successfully authenticated.
The `--traffic-url` URL must response the HTTP status code` 204`. Only when the traffic is reported will the report be considered successful, and if it response other status codes, it will be considered that the reported traffic failed, and the log will be output.
The proxy's http (s) / socks5 / sps proxy function supports a control interface, which can be specified by the parameter --control-url http interface address,
Then the proxy will interval send all the usernames or client IPs currently connected to the proxy to this URL. Specifically, the proxy sends an HTTP to POST request to the HTTP URL address set by --control-url.
`interval` defaults to 30 seconds, this value can be modified via the --control-sleep parameter.
When the user expires, or the user's traffic has been used up, the authentication API can only control the user cannot create a new connection, but the connection with the proxy has been established and the connection cannot be immediately disconnected.
Then this problem can be solved through the control interface. The control interface will return the content through the control interface in the slowest `interval` time, and the end is invalid when the user establishes the connection.
An HTTP POST request will be sent to the control. The interface `form` has three fields: interface, ip, conns, and the `conns` field requires a user whose proxy version is greater than proxy `12.2`.
`conns` The tcp connection information currently connecting to the proxy port to transmit data. The conns value is a json string, the format is a sequence of connections, the element is an object, the object contains the details of the connection,
Object field description: id: connection id, client: client's unique IP address and port, server: client's IP and no port access, user's connection authentication (null if any)
The data returned by the control interface is invalid user and IP or connection. The format is a json object data. There are three fields user, ip, and conns. The `conns` field requires the proxy version greater than or equal to `12.2`.
- The connection established by the returned user and ip will be disconnected by the proxy.
- Connections matching the returned conns will be disconnected by the proxy.
- If the returned data contains both: user or ip, and conns, then the user or ip will be ignored, and only the connection matching conns will be disconnected.
The proxy http(s)/socks5/sps proxy function supports the user to access the proxy pair through the configuration file, and supports the http(s) proxy ``Proxy Basic proxy authentication` and the socks5 proxy authentication.
### start using
The proxy's http(s)/socks5/sps proxy function can pass
`--auth-file`, `--max-conns`, `--ip-limit`, `--rate-limit`, `-a` These five parameters control.
#### Detailed explanation of parameters
##### `--auth-file`
The authenticated user name and password file. This parameter specifies a file, one line per rule, in the format: "username: password: number of connections: rate: upstream".
`Connection number` is the maximum number of connections for the user. The 'rate' is the maximum speed of each tcp connection of the user. The unit is: byte/second. The upper level is the upper level used by the user.
Not only can the authenticated user be set by `--auth-file`, but also the `-a` parameter can be set directly. Multiple users can repeat multiple `-a` parameters.
For example: `proxy http -a a:b:0:0: -a c:d:0:0:`
Example explanation:
For example: `user:pass:100:10240:http://192.168.1.1:3100`
`user` is the authentication username
`pass` is the authentication user password (cannot contain a colon:)
`100` is the maximum number of connections for this user, not limited to write 0
`10240` is the rate limit of this user's single tcp connection, the unit is: byte / sec, no limit write 0
`http://192.168.1.1:3100` is the upstream used by this user, no space is left blank
##### `--max-conns`
Limit the maximum number of global connections for the proxy service, a number, 0 is unrestricted, default is 0.
##### `--ip-limit`
Controls the number of connections and connection rate of the client IP. This parameter specifies a file, one rule per line, and the beginning of # is gaze.
The sample file ip.limit, the rule format is as follows:
`127.0.0.1:100:10240:http://192.168.1.1:3100`
Rule interpretation:
`127.0.0.1` is the IP to be restricted
`100` is the maximum number of connections for this IP, not limited to write 0
`10240` is the rate limit of IP single tcp connection, the unit is: byte / s, no limit write 0
`http://192.168.1.1:3100` is the upstream used by this IP, and it is not left blank.
##### `--rate-limit`
Limit the speed of each tcp connection of the service, for example: 100K 2000K 1M . 0 means unlimited, default 0.
## 11. Cluster
The proxy supports the cluster management. The proxy is installed on each machine node as an agent, with the control panel [`proxyadmin cluster edition`] (https://github.com/snail007/proxy-admin-cluster) Unified management of proxy services on massive machines.
If the proxy is to be run as an agent, assume that the cluster port address of the control panel is: `1.1.1.1: 55333`.
The command example is as follows:
`proxy agent -k xxx -c 1.1.1.1:55333 -i test`
Command explanation:
agent: is a function parameter, which means running agent mode.
-k : The encryption and decryption key for communication with `proxyadmin cluster edition`. This key is set in the configuration file of` proxyadmin cluster edition`.
-c : The cluster port address of `proxyadmin cluster edition`, format: IP:port.
-i ： The unique identifier of the agent ensures that each agent is different. The "unique identifier" specified here is used when adding a node to the control panel. The IP is filled with this "unique identifier".
If -i is not specified, the default is empty, and the control panel adds the IP field to fill in: the agent's internet IP.
-u: proxy parameter, empty by default. You can specify an agent, and the agent will communicate with the cluster through this agent.
The format is the same as that of `--jumper`. For details, please refer to the `--jumper` part of the manual.
notice:
When the client service is configured in the control panel, all nodes use the same key, which leads to only one client working. To solve this problem,
Client service parameters can use placeholders: `{AGENT_ID}` to refer to the agent’s id as the client’s key, so as to ensure that each client has a unique key.
For detail usage, please refer to the configuration file [rhttp.toml](https://github.com/snail007/goproxy/blob/master/rhttp.toml), which has a complete configuration description.
