ssh version 3.4p1-1and RSA authentification
Dear Debian users,
I've got problems with the new version of ssh and sshd.
My cluster originally installed on potato 2.2r6 needed some upgrade of ssh.
I installed ssh version 3.4p1.
Because the host keys had changed, I proceeded like this:
rm ~/.ssh/known_hosts
ssh node1
...
ssh node N
cp ~/.ssh/known_hosts /etc/ssh/ssh_known_hosts
The file /etc/ssh/shosts.equiv did not change, beacuse the nodes names are
the same.
I restarted /etc/init.d/ssh
It still ask for passwords...
I changed options in /etc/ssh/sshd_config, tried again. No change...
Could anybody help me?
Thanks in advance
Fabrice

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
