ssh over a proxy
Using ssh over a proxy can be made very simple when using putty on a Windows platform, but I always had to do very complicated stuff when trying this from cygwin and faced impossibilities from my FreeBSD boxes.
Now I found something nifty (that doesn’t mean that it didn’t exist, but I never searched for it), called corkscrew .
This tool is installed in your ssh_config (or your local config in ~/.ssh), like this:
# cat ~/.ssh/config Host * ProxyCommand corkscrew your.proxy.server 8080 %h %p
This line tells ssh to start corkscrew to connect to “your.proxy.server” on port 8080 (although this could be anything). I did this for all hosts (hence the “Host *”), but it can be configured for hosts indivually.
%h and %p are parameters for host and port, send to the host you’re trying to access.
When configured correctly, a ‘ssh yourhost’ will connect through the proxy server to your host.
