For whatever reason, with the OS X system-launched ssh-agent instance, ssh-add says it can't connect to it. If I launch my own ssh-agent, it works fine with that. The SSH_AUTH_SOCK envar is setup correctly, so I see no reason why it wouldn't work. So I am starting to suspect this has something more to do with OS X than ssh-agent<->libssh2 but I'm still just guessing.

So ssh-add -l sadly doesn't work.

ktrace is on OS X so I'll have to look into that later.

If I can figure out what the problem is, I'll happily contribute the code. :-) I've roughly heard it uses Keychain, but I don't know anything about the details. Do you have any more info on this? I'll gladly look into it if it's a potential solution.

I've posted in the Apple devforms as well incase anyone there knows what the problem might be.

Thanks Peter,
