ssh "eats" standard input when run in a shell loop:
tom@snoopy:~$ while read host
> do
> ssh $host cat /etc/issue.net
> done << EOF
> snoopy
> droopy
> pluto
> EOF
Debian GNU/Linux lenny/sid
prevents this annoying default behaviour
tom@snoopy:~$ while read host
> do
> ssh -n $host cat /etc/issue.net
> done << EOF
> snoopy
> droopy
> pluto
> EOF
