Hi, I was wondering if you could give me a pointer.
I'm ssh'ing to a machine where I'm trying to run gpg, which I hope to talk to the gpg-agent that's running on my local laptop, forwarded through ssh. I'm following the instructions at https://wiki.gnupg.org/AgentForwarding but I don't know how to make gpg use a specific Unix socket to communicate with my forwarded gpg-agent.
The problem is that there's already a gpg-agent running at the remote (I think started by systemd or the X server), which I don't want to disturb. For my ssh connection, I try to create a new Unix domain socket by using ssh -R /run/user/1000/gnupg/S.gpg-agent.remote:/Users/troy/.gnupg/S.gpg-agent.extra -o StreamLocalBindUnlink=yes -o ExitOnForwardFailure=yes
But then how do I make gpg use/run/user/1000/gnupg/S.gpg-agent.remote . It seems that gpg uses gpgconf to figure out that path. And there's no flag or envvar that I can use to override that (anymore).
The only thing I can think of is to specify a new --homedir so that the socket is created elsewhere, and then I'd have to change the port forwarding to reflect the dynamically-generated path which will look something like /run/user/1000/gnupg/d.xhmoxiusfxtwuy8s69hkyxtc . So either I have to do two separate ssh calls or I have to use an expect script to automate the addition of port forwarding on an existing session. Plus, now the homedir is different and all my files are in the wrong place.
I hope I'm missing something obvious. Thanks for any ideas. I'm using: - Ubuntu 22.04.1 LTS - gpg (GnuPG) 2.2.27 - OpenSSH_8.9p1 Ubuntu-3ubuntu0.1, OpenSSL 3.0.2 15 Mar 2022 Troy
