Hi, I have a little script (on a Suse 10.1 server) that creates a ssh tunnel to connect a MySql slave server with it's master. The script does something like this: while true; do ssh -oBatchMode=yes -L 33306:127.0.0.1:3306 -N root@someserver >>$LOG 2>&1 sleep 30 done The loop is to re-establish the connection when the netwerk connection goes down for some reason. This works ok, but when I run this script on a remote shell the script gets killed when I close the shell. So should I make a script in /etc/init.d to make this a more permanent solution, or is there a better way? And I also have the feeling the loop isn't the best solution for the problem? ;) -- Bye, Wilfred.

Hi Wilfred, I'd suggest that you use the "screen" command to make your script run permanently even when you close the remote shell. It's installed by default in SUSE 10.1 (/usr/bin/screen). Below a good quick tutorial: http://www.linuxforums.org/applications/the_screen_program.html Cheers, -mw

Agreed. "nohup" won't work, as "ssh" requires a terminal. So "screen" is one of the few options that will work. You can setup "screen" to automagically launch commands in whatever screen you wish when started. I.e., you should write your script to launch the commands under screen. The nice, additional benefit of this approach is that you can check on the status at any time by connecting to that running screen. -- Bryan P.S. Another option would be to dedicate tty8 or something to running this script. That would work on boot. -- Bryan J.

openvpn perhaps. Setting up a single tunnel with a static key is very, very easy. /Per Jessen, Zürich

Perhaps: ssh -f -oBatchMode=yes -L 33306:127.0.0.1:3306 -N root@someserver >>$LOG (-f added) -- Richard Bos Without a home the journey is endless
