Title: Cron Script for ping and restart of the opvn client every minute?
Post by: ckishappy on September 11, 2017, 01:35:32 pm

I just loaded opnsense on my old hp microserver Gen8 and opnsense is exactly what I was looking for. I get around 100Mbs with the OVPN client so will then buy some 1U decisio appliance soon to get some more speed with ovpn. I like the approach of the company.

Two questions:

1) I would like to run a cron script to ping an address every minute or so. If 6 pings fail, I would like to restart the ovpn client to ensure the client really reconnects to the vpn server. Please advise how I can do this?

2) I would like to run a cron script to see if the WAN is still up. If the WAN is down for more than a minute, I would like to restart the opensense server. Please advise how I can do this?

There's a couple of posts of mine (and a script) that should give you some ideas in this thread: https://forum.opnsense.org/index.php?topic=5511.0;topicseen

OpenVPN already has --ping-restart, is that not enough?

And rebooting the whole box every minute because the WAN link is down seems a bit drastic to me...

Thanks you are right that the server reboot is a bit dramatic. I use indeed keepalive. The wan connection is quite stable but still restarting the ovpn connection typically avoids any manual intervention throughout the day, week, month, year.

Is there a script just for the ovpnclient restart? in the log this is called rc.newwanip starting ovpnc1.. Pls advise?

Thanks for the sample script, do you know the command for restarting the WAN with a fixed IP?

If your ISP provides you with a fixed IP then the restarting the WAN interface will pick it up, I have a fixed IP on my internet connection. :) If you mean it's a specific IP that you have set then ifconfig can be used to set a specific IP in this format:

Code: [Select]

ifconfig vmx0  10.0.0.10/24
