You can kill the portmapper (port 111) in /etc/rc.conf by placing an override in there (find the override in /etc/defaults/rc.conf). Port 6000 is your X server - its best to firewall out 6000. -- Justin Stanford 082 7402741 jus@security.za.net www.security.za.net IT Security and Solutions On Fri, 9 Jun 2000 George.Giles@mcmail.vanderbilt.edu wrote: > > > I have enabled the simple firewall configuration on my kernel (FreeBSD 3.4).
