Or is there a way to say that only a certain domain or block of ip's can access my system? Also, is there a way to block the use of "adduser" or "vipw" or even looking at /etc/master.passwd without being the specific user "root". Where as you must be root and not "su" or any other user to see and/or use those commands. I hope that makes sense. I've having a bit of a security problem. =\ I'm using 4.2-RELEASE --- ------------------------------------------------------- | Jason P.
