Yes, it works for me. However, I tested it with the current development
version of 2.1 which adds an extra features:
Also listen on native gpg-agent connections on the given
socket. The intended use for this extra socket is to
setup a Unix domain socket forwarding from a remote
machine to this socket on the local machine. A gpg
running on the remote machine may then connect to the
local gpg-agent and use its private keys. This allows to
decrypt or sign data on a remote machine without exposing
the private keys to the remote machine.
The documentation on how to use Unix domain sockets with ssh is a bit
sparse. You probably want to use "-o StreamLocalBindUnlink=yes" when
connecting to the remote host and you have to enable the forwarding
features (look for Stream* options).
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
