Currently I am using openvpn3 client to connect to vpn server as

openvpn3 session-start --config /home/user/client.ovpn

then it asks for username and password.

Is there any easy way to pass username and password. Because everytime to enter username and password is annoying

You can pass username and password with printf using \n as a delimiter:

printf "MY_USERNAME\nMY_PASSWORD\n" | openvpn3 session-start --config client.ovpn

openvpn3 session-start as per https://github.com/OpenVPN/openvpn3-linux

See the instructions on https://community.openvpn.net/openvpn/wiki/OpenVPN3Linux how to install pre-built OpenVPN 3 Linux packages on Debian, Ubuntu, Fedora, Red Hat Enterprise Linux, CentOS and Scientific Linux.

When I did an upgrade to Fedora 36 the latest openvpn3-linux v18 client was built in. Did not have to manually upgrade / install it:

openvpn3-admin version --services

e.g: previous v17 suddenly stopped working spend 10 hours trying to debug with many "openvpn3 session-start":

openvpn3 config-import --config profile.udp.ovpn --persistent
openvpn3 config-manage --config profile.udp.ovpn --enable-legacy-algorithms true --show
openvpn3 session-start --config profile.udp.ovpn
openvpn3 sessions-list 
openvpn3 session-manage --config profile.udp.ovpn --disconnect

Actually thinking it was a cipher AES-256-CBC legacy issue that others were having. It was not for some reason, permissions on install of the OpenVPN3 Linux client? as it was NOT creating a TUN. So I made one myself (that was the actual issue):

sudo ip tuntap add name tun0 mode tun
sudo ip link show

and it connected after asking for VPN Username & Password, so added those to text file login.txt in the profile directory and auth-user-pass login.txt to profile.udp.ovpn so it would pass username and password automatically.

Another solution to pass the username and password is to use openvpn3-autoload

FYI more openvpn3-client session start help is here: https://github.com/OpenVPN/openvpn3-linux/issues?q=cipher

  • OpenVPN3 does not support `auth-user-pass`: https://openvpn.net/blog/openvpn-3-linux-and-auth-user-pass/ – Hubbitus Jan 27 '23 at 14:26

You can use this simple python script to connect to VPN:

import pexpect
from pexpect import popen_spawn

commands = "openvpn3 session-start --config profile-40.ovpn"
commands_list = commands.split(" ")
username = "x"
password = "x"

session = pexpect.popen_spawn.PopenSpawn(commands)
session.expect("Auth User name: ")
session.sendline(username)
print("first_done")

session.expect("Auth Password: ")
session.sendline(password)
print("second_done")
