Im logged in computer A and telnet from A to B, how can I execute a command like ifconfig in computer B and save the output of that command in a file in computer A? is there any way to do that? without ftping of telneting back to computer A?

telnet B | tee /var/log/telnet.log

I dont have the tee command

I don't think you can. Telnet was orginally built for dumb terminals to send commands to a server and view the results.

Maybe that's because your debian is messed up?
You need sh-utils. Try apt-get it or install it from source plz.
edit : after checking, the debian package is named coreutils
#apt-get install coreutils

Will dump the output to your current terminal provided hostB is running an SSH server.

or...
1. startx on A.
2. Open a terminal window on A (vi file to hold ifconfig info)
3. Open another terminal window on A and Telnet or ssh to B
4. do your ifconfig
5. cut and paste it into the vi file from step two.

No, actually I got it to work with this little piece of bad code.

#!/bin/bash
username=xxx
password=xxx
(sleep 1; echo $username; sleep 1; echo $password; sleep 1; echo "ifconfig ppp0"; sleep 1; echo "exit" |(telnet 192.168.10.1 &>/dev/null)>/tmp/fa.ip
cat /tmp/fa.ip|grep inet | head -1 | awk '/inet[\ ]*/ { print $2; }' | cut -d":" -f2>/tmp/fa.ip

thank you guys for the help.

Cs-cam: As Isuck said on a different thread ([s]he cross-posted this question , e.g., to http://www.linuxquestions.org/questi...php?p=2390748), the other computer is a router of som kind (busybox) and doesn't run an sshd.

Regarding Isuck's refusal of Agrouf's suggestion: You need tee on your local machine NOT on the router. And you should have it; IMO it's a basic UNIX command.

Isuck: Turn to the US government, National Institute of Standards. Seriously, http://expect.nist.gov/ sounds just like what you were looking for:
Run once, and it will write a script for you. If necessary, you can edit it.

BTW, I think that was an accidental smilie in your 2:02 post today. You can disable them.

A'right man, thanks
