i've done a bash script like this

while read site address do ssh $address "df -k" done

to repeat the remote command few times, but the loop works just once. Any idea on the reason of this behavior? Did i miss something?

Use the -n flag:

while read site address; do ssh -n $address "df -k";done

This tells ssh to leave stdin alone. Otherwise it will interfere with the next read command.
