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 DNS
### Ubuntu 18.04 (Bionic)
If your client is running Bionic (or another Linux that uses `systemd-resolved` for DNS but does not have `resolvectl` or `resolvconf` installed) you should first edit the config file. Comment out the line that begins with `DNS =` and replace it with:
```
PostUp = systemd-resolve -i %i --set-dns=172.16.0.1 --set-domain=~.
```
Use the IP address shown on the `DNS =` line (for most, this will be `172.16.0.1`). If the `DNS =` line contains multiple IP addresses, use multiple `--set-dns=` options.
### Ubuntu 18.10 (Cosmic) or 19.04 (Disco)
If your client is running Cosmic or Disco (or another Linux that uses `systemd-resolved` for DNS and has `resolvectl` but *not* `resolvconf` installed) you can either edit the config file as shown above for Bionic or run the following command once:
```
sudo ln -s /usr/bin/resolvectl /usr/bin/resolvconf
```
### Other Linux Distributions
On other Linux distributions you might need to install the `openresolv` package.
## Configure WireGuard
Finally, install the config file on your client as `/etc/wireguard/wg0.conf` and start WireGuard:
