Why not the following (done from the command line here quite often):
for I in linux01 linux02 linux3 linux4 ; do ssh $I 'ls /root' ; done
If you have a lot of penguins swimming around, put the names in a file, one
per line and do it this way:
for I in `cat penguins.list` ; do ssh $I 'ls /root' ; done
Of course, you could easily script this and generalize it to accept whatever
command you wanted from the command line. The for loop is easy enough,
though, that I haven't felt a compelling urge to do so.
