The -o option for ssh lets you type any line that is permitted in an ssh configuration file. In this case the proxy command specification from the previous task is used.
Specify the proxy commands and hosts in a configuration file.
Run ssh and include a proxy command specification as a -o option. For example, type:
% ssh -o'Proxycommand=/usr/lib/ssh/ssh-http-proxy-connect \ -h myProxyServer -p 8080 myOutsideHost 22' myOutsideHost
This command substitutes the HTTP proxy command for ssh, uses port 8080 and myProxyServer as the proxy server, and connects to port 22 on myOutsideHost.
