You should be able to capture the output of http://php.net/exec or
http://php.net/popen and do whatever you want with it.
fsockopen will, however, almost certainly be faster/better if you have to do
a lot of these.
I think telnet is port 22, usually... Or maybe 23. SSH is the other one of
those, and I always forget.
