Even simpler way to ssh through a firewall
In his article Jacky explained how to easily drill holes through to ports on machines behind a firewall. What I normally want is to have ssh access to machines behind firewalls, allowing me to do scp, and easily ssh in without a stupid stop-over on the firewall machine.
I came across this solution that does exactly that. After the super-simple set-up I’m able to do:
% ssh rexobox
% rcp rexobox:some-file .
All that’s required is to tweak your .ssh/config. Mine looks like this on my laptop:
Host rexobox
Hostname exobox
HostKeyAlias exobox
ProxyCommand ssh fw.exoweb.net nc -w 1 %h 22
… repeated for other hosts
