Applications will be run as the current user by default (you can use
vopono exec sudo -u USERNAME program as the command to run as another user).
vopono will call sudo if required, it is recommended to run as the current user and let vopono call sudo so that the configuration directories are correctly inferred and the final command is not run as root.
Note that child processes of the application will also be spawned inside the network namespace and so use the same VPN connection, so you can run entire shell sessions inside vopono.
Note that the order of command-line arguments matters, as the --dns
argument can take a list of DNS servers for example.
You can save default configuration options in the config file
~/.config/vopono/config.toml (or in the respective $XDG_CONFIG/vopono/
directory).
Here is an example:
firewall = "NfTables"
provider = "Mullvad"
protocol = "Wireguard"
server = "usa-us22"
postup = "/home/archie/postup.sh"
predown = "/home/archie/predown.sh"
user = "archie"
dns = "8.8.8.8"
# custom_config = "/home/user/vpn/mycustomconfig.ovpn"Note that the values are case-sensitive. If you use a custom config file then you should not set the provider or server (setting the protocol is also optional).
The current network namespace name is provided to the PostUp and PreDown
scripts in the environment variable $VOPONO_NS. It is temporarily set
when running these scripts only.
Similarly, the network namespace IP address is provided via $VOPONO_NS_IP,
and is available to the PostUp and PreDown scripts, and the application to
run itself. $VOPONO_NS_IP is useful if you'd like to configure a server
running within the network namespace to listen on its local IP address only
(see below, for more information on that).
The application to run within the namespace also has access to
$VOPONO_HOST_IP, to get the IP address of the host.
Note: These environment variables are currently only available from within the application/script to run, not on the command line. So the following doesn't work:
vopono exec {other Vopono options} 'echo "HOST IP: $VOPONO_HOST_IP"'
Output: HOST IP: $VOPONO_HOST_IP (the environ variable wasn't expanded).
A work around is to create a executable script, that executes the application you'd like to run:
#!/bin/bash
echo "=> NETWORK NAMESPACE IP: $VOPONO_NS_IP"
echo "=> HOST IP: $VOPONO_HOST_IP"Execution: vopono exec {other Vopono options} '/path/to/the/above/script.sh'
Output:
=> NETWORK NAMESPACE IP: 10.200.1.2
=> HOST IP: 10.200.1.1
Host scripts to run just after a network namespace is created and just before it is destroyed,
can be provided with the postup and predown arguments (or in the config.toml).
Note these scripts run on the host (outside the network namespace), using the current working directory,
and with the same user as the final application itself (which can be set
with the user argument or config file entry).
Script arguments (e.g. script.sh arg1 arg1), are currently not possible, resulting in an error:
$ vopono exec {other Vopono options} --postup 'echo POSTUP' ls
[...]
sudo: echo POSTUP: command not found
[...]
Install vopono and use vopono sync to
create the Wireguard configuration files (and generate a keypair if
necessary):
$ yay -S vopono-git
$ vopono syncRun vopono:
$ vopono exec --provider mullvad --server sweden --protocol wireguard "transmission-gtk"The server prefix will be searched against available servers (and country names) and a random one will be chosen (and reported in the terminal).
Note that vopono expects the AllowedIPs setting to allow all traffic,
since all traffic in the vopono network namespace will be forced through
this tunnel (traffic via the host is deliberately blocked to enforce the
killswitch). e.g. it should be AllowedIPs = 0.0.0.0/0,::/0
The sync menu will prompt you for any custom settings (i.e. ports used, and connection protocol for OpenVPN, etc.)
Valid ports for Mullvad Wireguard are: 53, 4000-33433, 33565-51820 and 52000-60000. The same is true for MozillaVPN since it is mostly a wrapper around Mullvad's Wireguard services.
Install vopono and use vopono sync to
create the OpenVPN configuration files and server lists.
$ yay -S vopono-git
$ vopono syncRun vopono:
$ vopono exec --provider privateinternetaccess --server poland "curl ifconfig.co/country"
PolandYou can also launch graphical applications like firefox,
transmission-gtk, etc. - the network namespace will be cleaned up when
the application is terminated. Note you may need to run them as your own
user:
$ vopono exec --provider privateinternetaccess --server mexico "firefox"The server prefix will be searched against available servers (both server names and aliases in the provider's configuration files) and a random one will be chosen (and reported in the terminal).
The sync process will save your credentials to a file in the config directory of the provider, so it can be passed to OpenVPN. If it is missing you will be prompted for your credentials.
For PrivateInternetAccess, HMA (HideMyAss) and AzireVPN these should be the same as your account credentials.
For TigerVPN you can view your OpenVPN credentials online on the "geeks" dashboard. The OpenVPN credentials are not the same as your TigerVPN account credentials.
For Mullvad your OpenVPN credentials are your account code as your username, and m as the password.
For ProtonVPN you can view your OpenVPN credentials online on your account dashboard. The OpenVPN credentials are not the same as your ProtonVPN account credentials.
For AirVPN the OpenVPN connection uses a key embedded in the config
files, however you will need to provide your AirVPN API key and enable
API access in the client area webpage when running vopono sync.
Note that ports for forwarding must also be added in the client area webpage,
and it is also possible to configure the VPN tunnel DNS settings there.
By default vopono uses the UDP configuration of the VPN providers.
You can use the TCP configurations by running vopono sync and choosing
that option from the provider configuration.
For Mullvad, valid ports are: 1300, 1301, 1302, 1194, 1195, 1196, 1197, or 53 for UDP, and 80 or 443 for TCP,
For PrivateInternetAccess valid ports are 1198 for UDP and 502 for TCP.
For TigerVPN valid ports are 1194 for UDP or 443 for TCP.
Mullvad supports proxying via Shadowsocks, if that configuration is
chosen with vopono sync. Note you must use a TCP connection on port
443 in this case.
Respond with Y when asked Connect via a bridge? during the vopono sync configuration for Mullvad OpenVPN to enable this configuration. It
is not used by default.
If you are using a custom provider config file, you must run the socks
proxy server yourself (i.e. ss-local) if using a socks-proxy.
If you use another commercial VPN provider, please open a Pull Request here with the necessary configuration and serverlist.
For private VPN connections, you can use a custom provider, by passing the complete configuration file to vopono (i.e. an OpenVPN .ovpn config file or a Wireguard wg-quick .conf file).
$ vopono -v exec --custom ~/custom_wireguard.conf --protocol wireguard "firefox"$ vopono -v exec --custom ./custom_openvpn.ovpn --protocol openvpn "firefox"To use a custom provider which requires a username and password, supply an authentication file with the username and password. Reference the authentication file in the ovpn configuration file with
auth-user-pass auth.txtappended to the top of the file.
Note that in the OpenVPN case the vopono will execute OpenVPN from the same directory as the config file itself. So any accompanying files (CA certificates, authentication files, etc.) must be in the same directory with the file if using relative paths in the config file.
OpenFortiVPN is supported as a custom provider, allowing you to connect to Fortinet VPN servers.
To use it, first create an OpenFortiVPN config file for your connection, such as:
myvpn.conf:
host = vpn.company.net
port = 443
username = myuser
password = mypassword
set-dns = 0
pppd-use-peerdns = 0
pppd-log = /tmp/pppd.log
You must set set-dns and pppd-use-peerdns to 0 so that
OpenFortiVPN does not try to change the global DNS settings (vopono will
set them within the network namespace). You must include the line:
pppd-log = /tmp/pppd.log as vopono uses this to read the pppd output
directly.
Then run vopono using this as the custom config file and specifying
OpenFortiVPN as the protocol. Note that if you do not specify your
password in the OpenFortiVPN config file then you must enter it when it
is waiting to connect (you will not be prompted).
vopono -v exec --protocol OpenFortiVPN --custom /home/user/myvpn.conf firefoxNote if running multiple Firefox sessions, they need to run separate profiles in order to force Firefox to run them as separate processes.
Trying to run Firefox normally when there is already an instance running will result in a silent error.
You should also disable DNS over HTTPS as this will send all DNS
requests to Cloudflare by default. Firefox Options > General >
Network settings > Settings, then deselect Enable DNS over HTTPS.
You may also wish to disable WebRTC - see Mullvad's guide for more details.
Similar issues apply to Chromium and Google Chrome, where you must provide a
different user-data-dir in order to force it to use a separate process:
$ chromium --user-data-dir=/tmp/profile-2If running servers and daemons inside of vopono, you can you use the
-f $PORT argument to allow incoming connections to a TCP port inside the namespace, by default this
port will also be proxied to your host machine at the same port number.
Note for same daemons you may need to use the -k keep-alive option in
case the process ID changes (you will then need to manually kill the
daemon after finishing).
For example, to launch transmission-daemon that is externally
accessible at 127.0.0.1:9091 (with outward connections via AzireVPN with Wireguard and a VPN server in Norway):
$ vopono -v exec -k -f 9091 --provider azirevpn --server norway "transmission-daemon -a *.*.*.*"Note in the case of transmission-daemon the -a *.*.*.* argument is
required to allow external connections to the daemon's web portal (your
host machine will now count as external to the network namespace).
Instead of listening on *.*.*.* you also can listen on $VOPONO_NS_IP,
to listen on an IP address that is only reachable from the same machine,
the network namespace runs on.
When finished with vopono, you must manually kill the
transmission-daemon since the PID changes (i.e. use killall).
The same approach also works for Jackett, e.g. with the setup from
the AUR PKGBUILD (a separate jackett user and hosting on port 9117):
$ vopono -v exec -u jackett "/usr/lib/jackett/jackett --NoRestart --NoUpdates --DataFolder /var/lib/jackett" -f 9117You can then access the web UI on the host machine at http:https://127.0.0.1:9117/UI/Dashboard, but all of Jackett's connections will go via the VPN.
By default, vopono runs a small TCP proxy to proxy the ports on your
host machine to the ports on the network namespace - if you do not want
this to run use the --no-proxy flag.
In this case, you can read the IP of the network namespace from the
terminal, or use $VOPONO_NS_IP to get it (e.g. to use it in a script).
For the above you may want to run vopono as a systemd service. If your user has passwordless sudo access you can use a user service, such as:
/etc/systemd/user/vopono.service:
[Service]
ExecStart=/usr/bin/vopono -v exec -k -f 9091 --protocol wireguard --provider mullvad --server romania "transmission-daemon -a *.*.*.*"
And then start it with (no sudo):
systemctl start --user vopono
If you do not have passwordless sudo access (i.e. privilege escalation requires entering the password) then you could use a root service and set up vopono on the root account. But note this issue currently makes this problematic for forwarding ports.
A popular use case is to run a proxy server like Privoxy inside the namespace with vopono, and then just configure Firefox, etc. to use that (so it connects via the VPN). This saves having to use Docker or LXC, etc. to do this otherwise.
Here is an example using AzireVPN and Wireguard (where the privoxy user was already created in the normal installation process):
$ vopono -v exec --provider azirevpn -k -u root -f 8118 --server norway "privoxy --chroot --user privoxy /etc/privoxy/config"Note we need to specify -u root so that privoxy has the permissions to
chroot later.
Port 8118 is then forwarded to the local host, so you can use the proxy
server normal. Note that just like with the transmission-daemon example
above, Privoxy must be configured to allow remote connections,
specifically in the config file you must not specify an IP address in
the listen-address:
listen-address :8118
Note that since the daemon forks to a new PID and does not set the
parent PID, you must use the -k option to keep vopono alive and then
manually kill Privoxy when finished with sudo killall privoxy.
If you have a better solution for handling the PIDs of daemons please create an issue / Pull Request!
The vopono list command lists running applications and namespaces, as
a tab separated table:
$ vopono list namespaces
namespace provider protocol num_applications uptime
vopono_tig_us_losangeles TigerVpn OpenVpn 2 28s
$ vopono list applications
namespace provider protocol application uptime
vopono_tig_us_losangeles TigerVpn OpenVpn firefox 36s
vopono_tig_us_losangeles TigerVpn OpenVpn lynx 15sThe --server argument is actually a prefix,
and you can see all possibilities for a given prefix and provider with:
$ vopono servers mullvad --prefix usa
provider protocol config_file
Mullvad openvpn usa-us.ovpn
Mullvad wireguard usa-us40.conf
Mullvad wireguard usa-us145.conf
Mullvad wireguard usa-us52.conf
...Mullvad users can use mullvad.net/en/check to check the security of their browser's connection. This was used with the Mullvad configuration to verify that there is no DNS leaking or BitTorrent leaking for both the OpenVPN and Wireguard configurations.
AzireVPN users can use their security check page for the same (note the instructions on disabling WebRTC). I noticed that when using IPv6 with OpenVPN it incorrectly states you are not connected via AzireVPN though (Wireguard works correctly).
There is no easy way to delete MozillaVPN devices (Wireguard keypairs), unlike Mullvad this cannot be done on the webpage. I recommend using MozWire to manage this.
iVPN Wireguard keypairs must be uploaded manually, as the Client Area is behind a captcha login.
Some providers allow port forwarding inside the tunnel, so you can open some ports inside the network namespace which can be accessed via the Wireguard/OpenVPN tunnel (this can be important for BitTorrent connectivity, etc.).
Mullvad tunnel port forwarding works for both Wireguard and OpenVPN. You will
need to enable the ports in your Mullvad account.
Remember to open the port with the -o PORTNUMBER argument to
vopono exec if you have the killswitch enabled!
For iVPN port forwarding also works the same way, however it is only
supported for OpenVPN on iVPN's side. So remember to pass
--protocol openvpn -o PORTNUMBER when trying it! Enable port
forwarding in the Port Forwarding page in the iVPN client area.
For AirVPN you must enable the port in the client area webpage,
and then use --protocol openvpn -o PORTNUMBER as for iVPN.
At the moment, either iptables or nftables is required (the firewall
choice can be chosen with the --firewall argument).
OpenVPN must be installed for using OpenVPN providers, and wireguard-tools must be installed for using Wireguard providers.
shadowsocks-libev must be installed for Shadowsocks support (Mullvad OpenVPN bridges).
