Even simpler way to ssh through a firewall

Saturday, October 27th, 2007

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
