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)

and my sshd_config
#PermitRootLogin yes

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

However i can still ssh in and remotly login directly as root.

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

Clues guys ?

Put the following in sshd_config and restart sshd : PermitRootLogin No
