[Tutor] Capture telnet output to a file?

[dpotter at nc.rr.com]

Hello,

I am trying to capture telnet output to a file.  For example I want to
telnet into a router and run the command “show arp” and be able to
capture all the arp information that normally would show up on the
screen to a file on my system.    I am using python and pexpect to
backup my router configurations on a daily basis, but for this the
router has the option to send the configuration via tftp to a server,
there is no option to send normal screen data to a file.  Any ideas?

Thank you.
