# Using Ubuntu as a Client with WireGuard
|
|
|
|
## Install WireGuard
|
|
|
|
To connect to your AlgoVPN using [WireGuard](https://www.wireguard.com) from Ubuntu, make sure your system is up-to-date then install WireGuard:
|
|
|
|
```shell
|
|
# Update your system:
|
|
sudo apt update && sudo apt upgrade
|
|
|
|
# If the file /var/run/reboot-required exists then reboot:
|
|
[ -e /var/run/reboot-required ] && sudo reboot
|
|
|
|
# Install WireGuard:
|
|
sudo apt install wireguard openresolv
|
|
```
|
|
|
|
For installation on other Linux distributions, see the [Installation](https://www.wireguard.com/install/) page on the WireGuard site.
|
|
|
|
## Locate the Config File
|
|
|
|
The Algo-generated config files for WireGuard are named `configs/<ip_address>/wireguard/<username>.conf` on the system where you ran `./algo`. One file was generated for each of the users you added to `config.cfg`. Each WireGuard client you connect to your AlgoVPN must use a different config file. Choose one of these files and copy it to your Linux client.
|
|
|
|
## Configure WireGuard
|
|
|
|
Finally, install the config file on your client as `/etc/wireguard/wg0.conf` and start WireGuard:
|
|
|
|
```shell
|
|
# Install the config file to the WireGuard configuration directory on your
|
|
# Linux client:
|
|
sudo install -o root -g root -m 600 <username>.conf /etc/wireguard/wg0.conf
|
|
|
|
# Start the WireGuard VPN:
|
|
sudo systemctl start wg-quick@wg0
|
|
|
|
# Check that it started properly:
|
|
sudo systemctl status wg-quick@wg0
|
|
|
|
# Verify the connection to the AlgoVPN:
|
|
sudo wg
|
|
|
|
# See that your client is using the IP address of your AlgoVPN:
|
|
curl ipv4.icanhazip.com
|
|
|
|
# Optionally configure the connection to come up at boot time:
|
|
sudo systemctl enable wg-quick@wg0
|
|
```
|
|
|
|
If your Linux distribution does not use `systemd` you can bring up WireGuard with `sudo wg-quick up wg0`.

|
## Using a DNS Search Domain
|
|
|
|
As of the `v1.0.20200510` release of `wireguard-tools` WireGuard supports setting a DNS search domain. In your `wg0.conf` file a non-numeric entry on the `DNS` line will be used as a search domain. For example this:
|
|
```
|
|
DNS = 172.27.153.31, fd00::b:991f, mydomain.com
|
|
```
|
|
will cause your `/etc/resolv.conf` to contain:
|
|
```
|
|
search mydomain.com
|
|
nameserver 172.27.153.31
|
|
nameserver fd00::b:991f
|
|
```
