This ssh proxy connect utilty documentation explains how to connect with your ssh client to a ssh server, located on the internet from a local network protected by a firewall or NAT through a proxy(HTTPS for example). Then show you how to configure your ssh client to use the proxy when ssh client tries to connect to your ssh server.

Requirement are :

• Your firewall has to allow HTTPS connections through a proxy
• You need to have root access to the server where ssh is listening

1. Install the connect software :

• Get source and compiling:

  $ cd /tmp/

  $ git clone https://github.com/ShuminHuang/ssh-proxy.git

  $ make

  $ sudo cp connect /usr/local/bin/ ; chmod +x /usr/local/bin/connect

2. Configure your ssh client.

• Open or create your ~/.ssh/config file and add these lines :

  Outside of the firewall, with HTTPS proxy

  Host my-ssh-server-host.net ProxyCommand connect -H proxy.free.fr:3128 %h 443

  Inside the firewall (do not use proxy)

  Host * ProxyCommand connect %h %p

3. Configure the ssh server.

• Edit this file (on debian system) /etc/ssh/sshd_config and add this line :

  Port 443

  Then restart the daemon :

  sudo /etc/init.d/ssh restart

$ ssh my-ssh-server-host.net

For example to connect to in ssh github.com :

Host github.com ProxyCommand=ssh my-ssh-server-host.net "/bin/nc -w1 %h %p"
