Hello. Both of these relate to my little FreeBSD firewall I set up. It's a 486 DX with 32MB RAM and a 250MB hard drive. Acting as a gateway for my cable modem. 1) Is there a way to tell sendmail to only send mail from localhost and to not relay at all? I turned on sendmail so I can get the daily security reports in the mail w/o having to log in, but don't want a spammer to find it and use it for a relay. Maybe it's that way by default, but I'd like to verify that. 2) How does /etc/hosts.deny work? I've got portsentry running on that box and whenever someone tickles it, it adds 'ALL: <IP>' to that file. Does another program run that reads this file? Since I wasn't really sure, and know a little more about ipfw, I turned on the ipfw feature of portsentry, and added a perl script to my boot up that reads the /etc/hosts.deny file and adds each IP to ipfw to deny all packets in that file (except those on my 192. addresses, just in case I do something stupid :) It's working, but I wanted to make sure I wasn't overriding something else. Thanks for the help, Rob
