Hi all,

I'd like to have a couple of ssh tunnels set up in my PC all the time. Is there any app to manage tunnels, start them when computer boots and keep them up (in case they go down for some reason)?

Cheers,

Paulo Matos

I've not come across anything like this, not for OpenSSH tunnels anyway. You could get clever and
write a little bash script to take care of starting the tunnels and just put it in /etc/conf.d/local.start

Here's a "template" file I use for my bash scripts....
Code:

#!/bin/bash

PIDFILE="/var/run/fork.pid"

function main {

        # print the pid of the forked daemon
        echo "forking to background ($[ $$ +1 ])"
        touch $PIDFILE
        echo $[ $$ +1 ] > $PIDFILE

        running="yes"
        while [ $running == "yes" ]; do

                echo Sample Code Here

        done

}

ARGV="$1"

# print program usage if no command line arguements are supplied
function usage {
        echo "Please run with "-d" to start the service in daemon mode"
        exit 0
}

# Check what was passed as an arguement and act accordingly
if [ "$ARGV" == "" ]; then
        usage
fi

if [ "$ARGV" == "-d" ]; then
        main &
fi


Hope this helps...

Thank you very much. In the meantime I also found autossh so joining your solution with autossh might be great! :D

Glad to help..I'd be interested to see the end result.

I think I tried autossh before and I'm not sure how well it worked....

Anyhoo...good luck :D
