copied!<p>Here's are 2 ways to accomplish it.</p> <h2>1st way</h2> <p>not sure if you've seen this thread?</p> <ul> <li><a href="https://groups.google.com/forum/?fromgroups=#!topic/capistrano/RVwMim-qnMg" rel="nofollow noreferrer">https://groups.google.com/forum/?fromgroups=#!topic/capistrano/RVwMim-qnMg</a></li> </ul> <p>It makes use of the <code>net-ssh-gateway</code> library, but creates copies of the local forwarding methods but they're geared for remote access.</p> <pre><code>class Net::SSH::Gateway # Opens a SSH tunnel from a port on a remote host to a given host and port # on the local side # (equivalent to openssh -R parameter) def open_remote(port, host, remote_port, remote_host = "127.0.0.1") ensure_open! @session_mutex.synchronize do @session.forward.remote(port, host, remote_port, remote_host) end if block_given? begin yield [remote_port, remote_host] ensure close_remote(remote_port, remote_host) end else return [remote_port, remote_host] end rescue Errno::EADDRINUSE retry end # Cancels port-forwarding over an open port that was previously opened via # open_remote. def close_remote(port, host = "127.0.0.1") ensure_open! @session_mutex.synchronize do @session.forward.cancel_remote(port, host) end end end </code></pre> <h2>2nd way</h2> <p>Outlined in an answer to this SO question:</p> <ul> <li><a href="https://stackoverflow.com/questions/2729100/is-it-possible-to-do-have-capistrano-do-a-checkout-over-a-reverse-ssh-tunnel">Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?</a></li> </ul> <p>This technique is very similar to the 1st way. First you need to create 2 paths to the repository:</p> <pre><code># deploy.rb set :local_repository, "ssh://git@serverbehindfirewall/path/to/project.git" set :repository, "ssh://git@localhost:9000/path/to/project.git" </code></pre> <p>Then before you deploy you'll need to setup the remote forward:</p> <pre><code>% ssh -R 9000:serverbehindfirewall:22 deploybot@deployserver.com # CTRL + C + A (Screen) or ⌘ + T (Terminal.app) to open new tab </code></pre> <p>Followed by your deploy:</p> <pre><code>% cap HOSTFILTER=deployserver.com deploy # HOSTFILTER reduces set to specified host. Only useful if you have multiple servers. </code></pre> <p>See this answer to that SO question for more details: </p> <ul> <li><a href="https://stackoverflow.com/a/3953351/33204">https://stackoverflow.com/a/3953351/33204</a></li> </ul>
