i2pd configuration

Command line options

Options specified on the command line take precedence over those in the config file. If you are upgrading your very old router (< 2.3.0) see also this page.

• --help - Show builtin help message (default value of option will be shown in braces)
• --conf= - Config file (default: ~/.i2pd/i2pd.conf or /var/lib/i2pd/i2pd.conf) This parameter will be silently ignored if the specified config file does not exist.
• --tunconf= - Tunnels config file (default: ~/.i2pd/tunnels.conf or /var/lib/i2pd/tunnels.conf)
• --pidfile= - Where to write pidfile (dont write by default)
• --log= - Logs destination: stdout, file (stdout if not set, file - otherwise, for compatibility)
• --logfile= - Path to logfile (default - autodetect)
• --loglevel= - Log messages above this level (debug, *info, warn, error)
• --datadir= - Path to storage of i2pd data (RI, keys, peer profiles, ...)
• --host= - Router external IP for incoming connections
• --port= - Port to listen for incoming connections (default: auto)
• --daemon - Router will go to background after start
• --service - Router will use system folders like '/var/lib/i2pd'
• --ipv6 - Enable communication through ipv6. false by default
• --notransit - Router will not accept transit tunnels at startup. false by default
• --floodfill - Router will be floodfill. false by default
• --bandwidth= - Bandwidth limit: integer in KBps or letters: L (32), O (256), P (2048), X (>9000)
• --family= - Name of a family, router belongs to

Windows-specific options:

• --svcctl= - Windows service management (--svcctl="install" or --svcctl="remove")
• --insomnia - Prevent system from sleeping
• --close= - Action on close: minimize, exit, ask

All options below still possible in cmdline, but better write it in config file:

• --http.address= - The address to listen on (HTTP server)

• --http.port= - The port to listen on (HTTP server)

• --httpproxy.address= - The address to listen on (HTTP Proxy)

• --httpproxy.port= - The port to listen on (HTTP Proxy) 4446 by default

• --httpproxy.keys= - optional keys file for proxy local destination (both HTTP and SOCKS)

• --httpproxy.enabled= - If HTTP proxy is enabled. true by default

• --socksproxy.address= - The address to listen on (SOCKS Proxy)

• --socksproxy.port= - The port to listen on (SOCKS Proxy). 4447 by default

• --socksproxy.keys= - optional keys file for proxy local destination (both HTTP and SOCKS)

• --socksproxy.enabled= - If SOCKS proxy is enabled. true by default

• --socksproxy.outproxy= - Address of outproxy. requests outside i2p will go there

• --socksproxy.outproxyport= - Outproxy remote port

• --sam.address= - The address to listen on (SAM bridge)

• --sam.port= - Port of SAM bridge. Usually 7656. SAM is off if not specified

• --sam.enabled= - If SAM is enabled. false by default

• --bob.address= - The address to listen on (BOB command channel)

• --bob.port= - Port of BOB command channel. Usually 2827. BOB is off if not specified

• --sam.enabled= - If BOB is enabled. false by default

• --i2pcontrol.address= - The address to listen on (I2P control service)

• --i2pcontrol.port= - Port of I2P control service. Usually 7650. I2PControl is off if not specified

• --i2pcontrol.enabled= - If I2P control is enabled. false by default

• --precomputation.elgamal= - Use ElGamal precomputated tables. false for x64 and true for other platforms by default

Config files

INI-like, syntax is the following : = . Comments are "#", not ";" as you may expect. See boost ticket All command-line parameters are allowed as keys, but note for those which contains dot (.).

For example:

i2pd.conf:

# comment
log = true
ipv6 = true
# settings for specific module
[httpproxy]
port = 4444
# ^^ this will be --httproxy.port= in cmdline
# another comment
[sam]
enabled = true

See also commented config with examples of all options in docs/i2pd.conf.

tunnels.conf:

# outgoing tunnel sample, to remote service
# mandatory parameters:
# * type -- always "client"
# * port -- local port to listen to
# * destination -- i2p hostname
# optional parameters (may be omitted)
# * keys -- our identity, if unset, will be generated on every startup,
#     if set and file missing, keys will be generated and placed to this file
# * address -- local interface to bind
# * signaturetype -- signature type for new destination. 0,1 or 7
[IRC]
type = client
address = 127.0.0.1
port = 6668
destination = irc.postman.i2p
keys = irc-keys.dat
#
# incoming tunnel sample, for local service
# mandatory parameters:
# * type -- "server" or "http"
# * host -- ip address of our service
# * port -- port of our service
# * keys -- file with LeaseSet of address in i2p
# optional parameters (may be omitted)
# * inport -- optional, i2p service port, if unset - the same as 'port'
# * accesslist -- comma-separated list of i2p addresses, allowed to connect
#    every address is b32 without '.b32.i2p' part
[LOCALSITE]
type = http
host = 127.0.0.1
port = 80
keys = site-keys.dat
#
[IRC-SERVER]
type = server
host = 127.0.0.1
port = 6667
keys = irc.dat
