Hi all,
In the network i'm managing there are about 15 RH Linux machines, from RH 7 to Fedora core 2.
i want to set up the SSH server on each WS so that ssh will ignore totally the auth. files residing in the users ~/.ssh dir.
and will only authenticate using host-based authentication.
1. the only file that i need to edit is the /etc/ssh/sshd_config ?, if not then what other files should i edit?
2. here is my current sshd config:
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
