What is "everything"? I've downloaded the lasg and have been reading
through it...but so far I have only disable things in
/etc/inetd.conf. Are there other locations that I need to be concerned with?

I know, that was one of the reasons it took me so long to get a cable
modem. I'm not too concerned about my systems (I tend to re-install
several times a year, and my home machines are a hobby--they don't put
food on the table), but I really don't want some cracker messing with
other systems via mine. But you has to step off the curb sometimes...
I've started playing with ssh, and so far everything seems fairly
straight forward. Once I get this stuff down Samba's next.
Thanks for you help!
