Public bug reported:
This bug concerns an interaction between ssh-askpass / gnome-keyring-
agent, ssh-agent, and ssh-add.
When I login, my two ssh public keys are automatically added to the
agent (by gnome, I think). I use ssh-add <keyname> to set the
passwords. I expect the agent now to know about all of my keys and
their pass phrases, but the agent seems to know about two copies of each
key, one with passphrase (which I provided) and one without (which it
auto-discovered).
jeff@nantes:.ssh $ ssh-add -l
2048 65:f6:25:dd:dc:39:19:08:75:cf:d3:34:1c:da:2b:1b jeff-@nantes (RSA)
2048 e1:a0:e1:38:4b:a0:27:68:bf:60:d8:4c:b4:ef:4c:c6 id_rsa.git (RSA)
2048 65:f6:25:dd:dc:39:19:08:75:cf:d3:34:1c:da:2b:1b id_rsa (RSA)
2048 e1:a0:e1:38:4b:a0:27:68:bf:60:d8:4c:b4:ef:4c:c6 jeff-git@nantes (RSA)
jeff@nantes:.ssh $ grep -H @ *pub | tr : ' ' | awk '{print $1 ":" $4}'
id_rsa.git.pub:jeff-git@nantes
id_rsa.pub:jeff-@nantes
jeff@nantes:.ssh $
Note that there are two key signatures above, each known twice by the
agent.
The result is that some ssh actions work fine (e.g., ssh depending on
the key in id_rsa.pub). But ssh depending on the key in id_rsa.git.pub
results in the keyring agent asking me for a key. Once I provide the
key, all is fine. But providing it is a bit of a bother, since the key
is long and hard to type, and the request window is modal, preventing me
from going and copying it from my password manager. And, anyway, my
goal was to provide all my keys on my own schedule, not at random points
in my workflow.
I am aware that what I am reporting involves a number of hidden steps
that I have deduced, and so possibly incorrectly. I'm certainly open to
actions to further define what is happening.
