Jay, I'm on Comcast in MD, and my DHCP lease is a bit longer - on the order of 3 months. Not sure if that is because I am a holdover of @Home or what. Just a note of caution, though. Comcast doesn't technically allow any kind of server. They will tolerate SMALL servers that don't generate a lot of bandwidth "under the radar" though. I have a *very* private FTP server, sshd and telnet (to my UPS). The rest is firewalled off. As unfair as it may seem, getting busted for running an FTP/HTTP server is worse than for running Kazaa or some other P2P crap. (despite the fact the latter tend to use more bandwidth) I get around the dhcp problem by having my system send me an email every morning - and looking at the headers. It's also a great way to get morning status from my systems. I thought about going to the DDNS route, until I heard stories of Comcast dropping customers who did this. There is also the fact that Comcast, unlike Millenium, doesn't actually block any ports (yet). (I think 25 may be an exception). I fear if very many people start trying to run servers and attach them to DNS records, Comcast may start blocking inbound ports as well. Yes, this warning is self-serving. If Comcast starts blocking ports, the only choice left is DSL - and I HATE verizon with a passion. They have screwed me over so many times, I lost count; and I dread the day I have to sign up for DSL because Comcast actually starts enforcing the "no server" rule strictly. Regards, Seth Henry Hello. I am on Comcast CABLE and the DHCP lease is only 4 days to expire, all the time. So my IP changes every four days. I was wondering in FreeBSD (FreeBSD4.8) how I can set up Dynamic DNS. I checked the online docs and I could not find anything on DDNS, is it some rc.x file or a file in /etc for me to edit? I would be more than happy if you got back with me A.S.A.P. Thanks. - Jay Buhrt
