problem with ssh from work to home

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I am running RHEL Linux at work and Ubuntu at home. I can ssh into
work from home but I can't ssh to home from work. When I try to ssh
into my home computer, I get no response.

I'm guessing that I need to open port 22 on my home computer or
something like that. Is that true? Can someone give me a clue about
how to do that or what else I need to do? I have Comcast cable and a
Netgear WNDR3700 router.

I think I have a dynamic IP address at home, but I've been told that
it won't change very often, so I'll be contented to just manually keep
track of it for now. However, I would like to know the best way to
figure out what it is at any given time. Thanks.

All your gear between the Internet and you pc will have to forward the
ssh port (grep -i ssh /etc/services) and not to mention your firewall
has to allow entry.  To play safe set firewall to allow work ip.
Of course sshd needs to be running to gain ssh access on your system.

You might want to try a few things from here that are applicable to
your setup.
