summary: Port-forwarding using Unix-domain sockets on the server
class: wish: This is a request for an enhancement.
difficulty: fun: Just needs tuits, and not many of them.
priority: low: We aren't sure whether to fix this or not.

OpenSSH has defined and implemented an extension to the SSH port forwarding system which allows the client to ask the server to make a connection to a Unix-domain socket instead of a TCP/IP endpoint, and in the reverse direction, to listen on a Unix-domain socket instead of a TCP port and forward incoming connections back to the client.

PuTTY doesn't currently implement that extension, but I don't expect it to be difficult in SSH protocol terms: it should be just a matter of formatting a couple of different kinds of channel request or global request.

(Probably the trickiest part is the user interface.)

See also forwarding-unix-sockets-client, which describes the use of Unix sockets at the client end (which PuTTY could do unilaterally without needing to implement a protocol extension). That could be done as an independent piece of work, though it would probably make thematic sense to do both together.
