Package: openssh-client Version: 1:5.1p1-5 Severity: important Recently, the ssh-agent instance started by xsession (as part of a GNOME desktop login) cannot use my public key, nor a newly generated passwordless RSA key.
After adding a new user, logging into a fresh desktop
session (no existing $HOME cruft), generating a new RSA key
with ssh-keygen -t rsa, no passphrase, and using ssh-add to
inject it into the agent, the following occurs
t...@ra:~$ ssh nj...@aldred.ncl.ac.uk
Agent admitted failure to sign using the key.
nj...@aldred.ncl.ac.uk's password:
With my normal user and key, I don't get that failure
message.
-vvv output attached to report as 'attempt2'.
Strangely, both with this test environment and with my own
setup and key, if I do eval `ssh-agent`;ssh-add , all works
as expected, so it appears to be something to do with the
way in which ssh-agent is invoked by xsession (defined in
/etc/X11/Xsession.d/90x11-common_ssh-agent from package
x11-common it would seem) rather than ssh-agent itself.
The ssh-agent started by xsession is
/usr/bin/ssh-agent /usr/bin/gpg-agent --daemon --sh
--write-env-file=/home/jon/.gnupg/gpg-agent-info-ra
/usr/bin/dbus-launch --exit-with-session
x-session-manager
This is rather crippling my day to day work :(
Any hints on where to look further would be much
appreciated.
