Just an FYI, you do NOT want to use /etc/default/login (due to many security
issues) with SSHD if you can avoid it (unless you need the BSM audit trail).

Hi,

OpenSSH will read /etc/default/login if 'UseLogin' is set to 'yes' in
sshd_config.

If a line is commented out it indicates this is the default behaviour,
so you will need to uncomment and change PermitRootLogin to 'No' and
then either restart sshd, or send a kill -1 to the sshd process (make
sure you get the right process id....)

Regards,

Craig.

OpenSSH doesn't read /etc/default/login (nor does Solaris 9 SSH,
although Solaris 10 does)

OK, so it's commented out and thus the default will be in effect.

So it sounds like the default value for PermitRootLogin is Yes.

Put the following in sshd_config and restart sshd : PermitRootLogin No
