Net-SSH Prompts for Passphrase even with keys loaded in ssh-agent
Reported by adlongwell | April 20th, 2011 @ 07:41 PM
I formerly had version 2.0.24 of Net::SSH. After upgrading, I'm suddenly prompted for my private key passphrase on every connection even though I have ssh-agent running with the key loaded. An ssh connection in the same terminal window connects fine to the same server with no passphrase request.
I noticed the problem through Capistrano, but the problem is reproducible with a simple Net::SSH script directly.
I downgraded back to 2.0.24 and the problem was fixed. After up and downgrading each version between 2.0.24 and the latest, I've narrowed the problem to this commit:
https://github.com/net-ssh/net-ssh/commit/05601f7e650942ecea1e5d179...
My key file is ~/.ssh/id_dsa, but I do not have a ~/.ssh/id_dsa.pub file with my public key in the ~/.ssh directory. I haven't debugged in code, but I believe something about that commit is causing the file-based lookups to start ignoring the data received from ssh-agent.
My assumptions seem correct, because creating an id_dsa.pub file containing my public key also fixes the problem.

The same problem. Used many keys, but without pub. Do 'ssh-add', but always need enter passphrase again. This is not good, because for capistrano-ext I cann't deploy. Problem solved only downgrade to net-ssh 2.0.24.

+1 I have the same problem (and, also no
.pubversion of my key…) I'll try to draw Delano's attention to this ticket. -

Thanks for the detailed report and confirmation guys. I'll forward this issue to the committer of that pull request (Net::SSH is in maintenance mode so most of the changes happen via patches).
