Remote forwarding of sockets not working

[kchr]

Hi,

When attempting to do a remote/reverse forward of a socket, the application throws a warning and the socket is not present in the remote container:

$ ls -la /tmp/socket-client       
srwxr-xr-x 1 user users 0 Aug  6 19:53 /tmp/socket-client
$ ssh -p 2222 -R /tmp/socket-server:/tmp/socket-client alpine-gui-test~user@robot ls -l /tmp/socket-server

Warning: remote port forwarding failed for listen path /tmp/socket-server
ls: /tmp/socket-server: No such file or directory

Looking at the source code, it seems that forwarding sockets may not be supported?

For example, the two types that seems to be used for remote/reverse forwarding expects an address and port:

• remoteForwardRequest
• remoteForwardChannelData
