    Hi there!

    I'm running TomatoUSB (v1.28.20111009 MIPSR2-beta-tomato-RT-N-GIT K26 USB VPN) on my Netgear 3500L. I set up a VPN Server and it's running pretty perfect. Nevertheless i want to run a litte OpenVPN watchdog, just to be prepared if something goes wrong and the process stops working.... but sadly i've no clue about scripting / coding.

    When the server's running properly, the "ps" looks like this:

    811 root 7000 S /etc/openvpn/vpnserver1 --cd /etc/openvpn/server1 --

    so how can i monitor this process? is anybody running such a script and would share it with me? Any hints are welcome! :)

    thanks a lot, i appreciate that!

    "Poll Interval" is the Parameter you are looking for (advanced - TAB in the VPN-GUI). If activated (=entered anything other than 0) than there is a periodically check if the VPN is running, and restart it if not.

    The log will be flooded with VPN_LOG_NOTE by the Poll Interval feature.

    correct, as i can see! ...but that's not a big deal, right? Or do you think this is causing any problems?

    thanks, alfred! :)

    No, not too much problem if you don't always check the log for the manage requirements, but I do. Or, perhaps it can be quieted down by the verbose setting, I didn't test it yet.

    Generally, I don't worry about if OpenVPN stops running, I have two sets of site-to-site VPN running over years, they are very stable and never get down. If they lost the connection in each other, I can see it were all caused by the ISP's sake. They will be automatically reconnected again after the ISP had their problem fixed.
