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.
