Sometimes I need to ssh to my servers back at school when working in the company; Since the corporate proxy servers support HTTPS and don't block connections to port 22, ssh over proxy is possible, and here is what I did to make it work:
- Install connect-proxy:
apt-get install connect-proxy
The debian package description is pretty clear in describing its functions:
Description: Establish TCP connection using SOCKS4/5 and HTTP tunnelconnect-proxy is a simple relaying command to make TCP network connectionvia SOCKS or https proxies.It is mainly intended to be used as proxy command of OpenSSH.
- Edit ~/.ssh/config and add the following lines (modify to suit your needs):
# not using proxy on lan Host 172.16.* ProxyCommand connect-proxy %h %p Host localhost ProxyCommand connect-proxy %h %p # mandatory to access the internet Host * ProxyCommand connect-proxy -H proxyserver:proxyport %h %p
Now when you run ssh to connect to servers not on your LAN, connect-proxy is used along transparently.
