To connect to your AlgoVPN using WireGuard from Ubuntu, first install WireGuard:
# Ubuntu 19.04 and earlier: # Add the WireGuard repository sudo add-apt-repository ppa:wireguard/wireguard # Ubuntu 17.10 and earlier: # Update the list of available packages sudo apt update # Install the tools and kernel module: sudo apt install wireguard openresolv
For installation on other Linux distributions, see the Installation page on the WireGuard site.
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.
Finally, install the config file on your client as
/etc/wireguard/wg0.conf and start WireGuard:
# 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.
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
If you’re using the version of WireGuard included with Ubuntu as of 19.10 it might be from before this feature was added. To use the latest version of WireGuard add the PPA repository as shown above.
Note that using the PPA repository on Ubuntu 20.04 LTS instead of the WireGuard modules shipped in the kernel package may cause the installation of about 40 additional packages in order to compile the kernel module.
