The SSH server’s configuration file is /etc/ssh/sshd_config
.
By default OpenSSH permits users (including root!) to login with their username/password combination.
SSH server configuration file:
/etc/ssh/sshd_config
To make changes effective, always restart the SSH service:
# /etc/init.d/sshd restart
Prevent root login
Setting in /etc/ssh/sshd_config
the PermitRootLogin
option to no
the SSH server
does not allow root to login. You can still use su
after you have succesfully logged
in as a normal user.
PermitRootLogin no
Limit SSH access to a limited group of users
As an extra security measure, you can create a new group on the server machine and configure the SSH server to allow remote connections only for users member of that group.
AllowGroups <group name>
Setup the SSH server to use certificates for authentication
See the NFS page.
