SSH through a mean firewall? 2

[venkman]

I work at a company with a mean firewall that only allows http and https connections. I do nothing all day, and would like to be able to ssh or telnet to my web server running at home and do some php coding when I get bored. Is it possible to setup an ssh or telnet connection on port 80 or the https port, whose number is eluding me right now, and trick the firewall into thinking I'm just setting up an HTTP connection? Are firewalls/proxies more complicated than that?

If the firewall just filters packets based on IP and PORT, like ipchains you just have to change your port# on your ssh-server to 443 (HTTPS) and use that one..

If the firewall is proxybased you may be in deep $hit.. However ssh uses SSL in the same manner as HTTPS so you may still cheat the it by using port 443.

um, shouldn't you be looking for something to do involving work? Ok, now that my consciense is appeased, try
'ssh -L 80:host:22 -R 22:host:80'. I think that should work

As for why I do nothing at work... times are tight, and being unable to find SQA work, I had to start temping as an assistant (aka secretary).

Anyway, thanks for the responses, also, how do I start running my ssh server to accept connections on 443? I'm running whatever the default ssh server is that comes with redhat 7.3. I apologize for not even trying to look this up myself, but I figured I'd ask first while I have your attention.

Thanks,

check out /etc/ssh/sshd_config.

just edit /etc/ssh/sshd_config and add/change the line with port specs to
Port 443

and then just restart the server
