Re: Is it possible to forward unix sockets?

[Graham Percival <gperciva@tarsnap.com>]

Yes, spiped is trying to bind the /tmp/blah socket, yet the file /tmp/blah
already exists.  Please delete that file, then run your spiped -e command, and
then run the other program which you want to send data to /tmp/blah.

(if that other program is also trying to bind /tmp/blah, then it probably needs
to be re-thought.  The "server" program is the one which binds the socket; the
"client" program merely connects to it.)

Cheers,
- Graham
