---------------------------------------

             Summary: [SFTP] Stream (e.g. netcat) proxy for Sftp file system (aka ProxyCommand)
                 Key: VFS-440
                 URL: https://issues.apache.org/jira/browse/VFS-440
             Project: Commons VFS
          Issue Type: Improvement
            Reporter: Benjamin Piwowarski
            Priority: Minor
         Attachments: sftp-stream-proxy.diff

What I propose is to add the possibility to connect to a remote SSH server through an SSH
connection stream (instead of an HTTP or SOCKS proxy). See for instance

http://backdrift.org/transparent-proxy-with-ssh

for a use case.

This simulates a ProxyCommand where the command is run on a SSH host.
The patch also contains a test for the new functionality. 

Example of use (with the netcat command nc -q 0 HOSTNAME PORT)
{code:java}
builder.setProxyType(opts, SftpFileSystemConfigBuilder.PROXY_STREAM);
builder.setProxyCommand(opts, SftpStreamProxy.NETCAT_COMMAND);
builder.setProxyHost(opts, "gate.way.host");
builder.setProxyPort(opts, 22);
builder.setProxyOptions(opts, proxyOptions);
{code}
