Block telnet and ssh access to user

In solaris you can stop root access except for the console (/etc/default/login)

Is there any way you can do this for normal users and only allow 'su' to that user - lets say only give 'user1' console access and user2 needs to 'su - user1' to gain access

I'd not use telnet at all, as it is insecure, so don't start that daemon. I don't use Solaris, but it is probably similar to linux, which I do use. You can get a copy of webmin and manage SSH and other settings using it. This will change the settings in your sshdconfig file.

Agree regarding telnet. I'd just switch it off.

The SSH config files are in the same place as with Linux. /etc/ssh/sshd_config and you can use the DenyUsers directive to prevent specified users from logging in via ssh. Obviously remember to do a quick svcadm restart network/ssh to activate changes to the config file.

dont know why I mentioned telnet in my subject as I already disabled that in /etc/inetd.conf

Alex - adding the user to the 'DenyUsers' directive in sshd_config worked like a treat

Thanks for all your help
