The simplist thing is not having any unnecessary daemons running. Closing off everything but the most needed daemons will grately improve the security of the linux box. Usually what I do is close off everything in /etc/inetd.conf and only open what I need. Also, I do netstat -a |grep LISTEN to see what all ports ar listening and close off any services that I don't want. In addition running a firewall such as ipchain or iptalbe script can help a lot. With all these things done you should have a hack free linux box. --- Raul A. Gallegos mailto:raul@asmodean.net http://www.asmodean.net For millions of years, mankind lived just like the animals..
