What I forgot to mention is that before I rebooted, I checked things out with tcpdump, which showed a lot of activity from my previous IP address, even though attempts to reach that address, either from this box in question or another person's machine located 20 miles away (I phoned him), by any method (ping, telnet, ftp) failed. That person also tried reaching my machine by the IP address ifconfig said I had, and he received no data back once connected either by FTP or telnet, however he was getting responses to PING requests. Did NATD take a dive when my IP address changed? -- ___________________________________ _____ _____ | _///@@@| | | natedac@kscable.com /'//ZZ@@|____ | | |'''/ |'/@7 | | http://home.kscable.com/natedac |`'| `~~' | | | `| .--. | | C64/C128 - What's *YOUR* hobby? | `\____|___\ | | \_ | | |___________________________________ \_____| _____| To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
