Problem with unix socket forwarding

[Andrew Gallagher]

Hi, all.

I've been trying to get gpg-agent forwarding working between my laptop
and a remote VM. Using the new unix socket forwarding in openssh 6.7, I
have defined the following script:


ssh -R /home/andrewg/.gnupg/S.gpg-agent:$( echo $GPG_AGENT_INFO | sed
's/:.*//g' ) -o "ControlMaster=no" -o "ControlPath=no" -o
"StreamLocalBindUnlink=yes" $*


gpg-agent on the VM indicates that the socket is live, but gpg2 reports
no private keys available. I have one local and one smartcard private
key working perfectly on the laptop (see below).

Anyone know where I'm going wrong?

On a side note, the option StreamLocalBindUnlink=yes appears to do
nothing, meaning I'm constantly having to rm .gnupg/S.gpg-agent - any
help with that would also be appreciated. ;-)

Thanks in advance,

Andrew.
