connecting to telnet

[Ambrotos]

Ladies and Gents,

Does anyone know of how to connect to a telnet session using php. I tried going through the php manual but it confused the heck outta me.

Thanks for your assistance

Open a socket to 23 on the remote machine.

Read the manual about: fsockopen()

Anyway, don't forget that you can't easily use a PHP script as a terminal window. It runs, then stops. There is no connection that is constant, like in a real telnet session.

I agree that its no use for realtime telnet, there are other uses though, like connecting to a router to get some info out (like doing 'sh proc cpu' on a cisco, outputting the comeback etc).

don't forget also that PHP can (depending on your server permissions of course) simple execute (via system(), exec(), or `` backtics) the direct telnet command.

exec("telnet to.somewhere.com");

that's not interactive though, it would only let you check the output, for instance to see if the server responded correctly.

BUT, using linux and |, you could do:

exec("echo 'sh proc cpu' | telnet to.somewhere.com");

to execute a single command.
