[gentoo-dev] SSHD problems

[Chad Huneycutt]

I have had this problem for a while now, and I am finally ready to get
rid of it.  I have a gcc-2.95 Gentoo machine with openssh 3.5_p1 and
OpenSSL 0.9.6g.  I use keychain/ssh-agent for authentication on the
remote box, rebo, and it works fine on every other system I have ever
tried to log into.

Here is what happens.  My server, goliath, has sshd running (configured
with the attached sshd_config file, and my user account on goliath has
the ~/.ssh/id_dsa.pub from rebo in the ~/.ssh/authorized_keys2 file. 
This should be sufficient to allow passphrase-authenticated login,
keychain or no.  And it does kind of work.  Here is a sample session

chadh@rebo chadh $ ssh goliath
Enter passphrase for key '/home/chadh/.ssh/id_dsa': <wrong passphrase>
Enter passphrase for key '/home/chadh/.ssh/id_dsa': <correct passphrase>
chadh@goliath's password: <correct password>
chadh@goliath chadh $

So it is like the passphrase authentication works, but then I also have
to go through the password authentication as well.

Has anybody else had this problem or have an idea as to how to fix it. 
It is quite annoying, since it only occurs when I try to login to
goliath (and the user account is set up identically to all of my other
user accounts).  It seems like it must be a problem with sshd, but I
don't see any obvious options in sshd_config to cause it.  I don't know
enough about PAM to diagnose problems there, but I am using the default
Gentoo PAM config files.

Thanks.
