Hi
I am a relative Linux newbie, and have several linux boxes to learn on. I want to stop and start the client on demand, and have been ssh'ing in to start them individually. I would like to start the program on all 5 boxes with a script. I have setup ssh to use keys rather than a password so the script logs in automatically without a password prompt, and tried a simple script:
ssh <client1 IP> <command>
ssh <client2 IP> <command> etc

The problem is that the script starts up the first client but the first line doesn't complete so the 2nd client isn't started. I have been cheating by running the same script 5 times as after the error message client already running it moves onto the next line. I would like the script to open each client in a seperate terminal window so I can keep tabs on what the machines are up to. Any scripting advice would be welcome.

Thanks
Ross

You can start the ssh with the -f option, and all start the boinc client in the background.

A short example, for the thing you would do. It starts command on client1 and client2 and logs the output to $LOGFILE ($LOGFILE is the path and filename where the outputs of <command> should be logged :

#!/bin/sh
ssh  -f "<client1 IP> <command> > $LOGFILE 2>&1 " &
ssh  -f "<client1 IP> <command> > $LOGFILE 2>&1 " &
