Hello,

We recently deployed warpgate at work. It's all together great, but we're running in to the following issue:

Given a service listening on an UNIX socket. For example:

user@target $ socat UNIX-LISTEN:/tmp/test.sock,reuseaddr,fork STDOUT

A direct SSH connection with a local forwarding rule to the target host works:

ssh -L 127.0.0.1:5901:/tmp/test.sock 'user@target'
echo "ok" | socat STDIN TCP4-CONNECT:127.0.0.1:5901   
# "ok" printed on target

However, when connecting through warpgate:

ssh -L 127.0.0.1:5901:/tmp/test.sock 'warpuser:target@warpserver' -p 2222
echo "ok" | socat STDIN TCP4-CONNECT:127.0.0.1:5901   
# channel 2: open failed: unknown channel type: Unknown channel type

Forwarding between INET sockets (e.g. -L 9999:localhost:9999) works as expected. It would be convenient if it also worked for UNIX sockets.

Thanks,
Georgi
