Thanks! I'll give that a try when I get back to the office.

I am trying to establish a reverse shell from a linux computer of mine at
work, behind a firewall/router that does NAT to a linux computer of mine at
home so I can access files when I work at home. Both are Ubuntu 10.
I'm doing it the ssh way rather than the netcat way, e.g. on the machine at
work, it's:
ssh -NR 3333:localhost:22 [email protected]
and at home, it's:
ssh myname@localhost -P 3333
This works fine once established. I can remotely log in on my home box while
at work and use the reverse shell. But...
Usually, by the time I finish my commute home, the connection has dropped.
I assume it has timed out.
Is there a way to keep this alive for extended periods of time?

Also poke through the /etc/sshd_config on the remote host. I have many
servers which drop after inactivity for security purposes. (see man
sshd_config)
Also consider some form of dynamic DNS service - most are free, and
can make things work in a pinch. On many ISP's TOS it's technically
illegal (the legal-ese reads "Run any form of server" so even a lot of
things they don't care about are technically illegal) but if you're
not serving the public over the residential connection you should be
fine.
