http://www.isc.org I'd suggest starting with these folks. Dynamic DNS sounds like what you're looking for. I guess it took me a couple of hours to figure it out the first time but it really isn't all that complicated. Also, it isn't so much that DNS works with DHCP but rather, DHCP can be set up to update DNS so long as DNS is set up to receive updates from DHCP. There are rules set up for allowing your DHCP daemon to update the DNS server with each IP address it leases (and removing those entries when they expire). It's all pretty slick and works very well. I have set it up on probably a dozen systems now. If you used the ISC Bind (you probably do) and DHCP (you don't) packages I could probably set you with some template files I always use - makes it so I don't have to memorize everything. Maybe this would make a good addition to a howto somewhere... The fly I see in this ointment is in regard to the fact that your linksys router is doing DHCP on your network. You'd have to determine whether the linksys can be configured to do the updates. If it can't, you're pretty much stuck unless you're willing to take the DHCP services off the linksys and put them elsewhere (like on the same box that runs DNS). For more info you can also look at some man pages - best info of these two is in ISC's dhcpd.conf man page. man named.conf (requires the named (Bind) packages) look for allow-update man dhcpd.conf (requires ISC dhcpd package) whole section on dynamic dns Hope this helps. -- Mike Rambo [EMAIL PROTECTED]
