Kurt - I just signed up this week to the mailing list, so I wasn't around
to respond last week.
The problem you are having is due to the new implementation of SSHD for
woody. What you need to do is modify the /etc/ssh/sshd_config file to
include the dsa key... to do this the following needs to be done to
sshd_config
Where you have the line :-
HostKey /etc/ssh/ssh_host_key
Add after it the following two lines :-
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
This will fix the problem when you restart sshd.
The update script does not modify the sshd_config file for a variety of
good reasons, and I cannot remember if it even includes the new config
file or not.
The latest implementation uses one keyfile for both protocols, but at the
moment as far as I know, the latest version is yet to hit even unstable in
Debian. (Good choice in my opinion... let's see how it works before
adding extra hassles).
Regards,
Cassandra
