OpenSSH using your HTTP PROXY
It is very easy to let openSSH use a proxy for his connection. All you have to do is write a simple configuration in your ~/.ssh/config file
Host webhost-over-proxy
User myuser
HostName myhostorip
Port 443
ServerAliveInterval 30
ProxyCommand nc -v -x your.proxy.host:80 -X connect ?%h %p
All you have to do now is just type ssh webhost-over-proxy or ssh -v to see some debug messages and it will be transported transparent over the proxy.
