Thanks for the sud tip btw. This is truly a killer app in
system-administration of an LTSP system. If I generate ssh-keys for my
machines I can netstat them like this from my commandline:

ssh <ipaddress1> netstat -t -e ..........

and it returns all users from <ipaddress1>

then I can do ssh <ipaddress1> netstat -t -e ..........  and so on.

Is this usable for you in any way? How should the line in the code look
like now? With five servers to list?
