Re: [PLUG] PnP Modem Continued...


Safest thing to do, if you're not an ISP, is to put "ALL: ALL" in
hosts.deny, and just put in hosts.allow the places you'll be connecting
from, or the places you want people and/or services to connect from.

Example:  My hosts.allow looks something like this (I'm not at home
right now):

ALL: .netaxs.com
ALL: .earthstation.net

I did this so that I can leave my computer connected when I leave for
work and telnet/ssh into it from work.

The docs will tell you that tcpd reads hosts.allow first, and then
hosts.deny, so obviously, this lets me use all services (before the
colon is which services you're specifying, like "ALL" or
"IN.telnetd") from any domain ending with netaxs.com or
earthstation.net.  (Y'all only use the knowledge of my machine for
*good*, mmkay? ;)
