View source for OpenVPN Linux auto-restart

== Intro ==
There are basically two files to install on linux
* openvpn-restart.service
* restart_openvpn.py

You can get these files from [https://github.com/koss822/misc/tree/master/Linux/Projects/openvpn/restart/linux Github.com]

Propably interesting is how these scripts works

<syntaxhighlight lang="Python" line='line'>
#!/usr/bin/env python3
import os,time
def reachable():
    for i in range(0,3):
        time.sleep(60)
        if os.system('ping -c1 YOUR_VPN_SERVER_PRIVATE_IP 2>&1 > /dev/null') == 0:
            print('ping succesfull')
            return True
        print('host unreachable')
    return False



while(True):
    if reachable():
        continue
    print('restarting openvpn')
    os.system('systemctl restart openvpn@YOUR_CONFIG_NAME.service')
</syntaxhighlight>

== How to set-up ==
# Replace YOUR_VPN_SERVER_PRIVATE_IP with your OpenVPN gateway IP - this IP is permanently pinged and if it goes down openvpn process is restarted
# Replace YOUR_CONFIG_NAME with name of your openvpn client config in /etc/openvpn, e.g. ''/etc/openvpn/'''client'''.conf'' means '''CLIENT''' as '''YOUR_CONFIG_NAME'''
