[CentOS] Bash scripting - Remotely ran commands break while loop

I have two CentOS5 systems server1 and server2. There is user peter on server1 who can ssh to server2 using public ssh keys and no password is needed.

What I noticed is that running remote ssh commands in bash script breaks while loops.

====== #!/bin/sh for i in server2 server2; do echo "--> Start" ssh peter@$i ls echo "--> END" done

echo " server2 server2" | \ while read confLine; do echo "--> $confLine" ssh peter@$confLine ls echo "--> END $confLine" done ====

The "for" loop in the script above will run twice but the "while" loop below it will run only once.

This is very simple to test and I've tried it on different systems including CentOS6 and OpenSolaris with the same result.

Any idea what would cause the ssh command to break the while loop?

Thanks Peter
