So, I have been trying to get a local DNS, DHCP, and SMTP server set up on my home network, so that I can have nice name resolution and static IP assignment based on MAC address, since my linksys router doesn't do that. I seem to have gotten exim configure to a point now where it seems like it will work as I want it to. However, it appears that my machine is unable to route to a large number of MX hosts. I keep getting "connection timed out" errors in the exim logs. For DNS, I've configured a master zone for BIND in the yast2 config UI, and 3 A record entries for hosts on my internal network. However, when I do "nslookup foo" for a host A record that I defined, I either get an NXDOMAIN or SERVFAIL (if I specify the full domain). I have no idea why. The forwarding works fine, and it gives me proper results for external hosts like google.com or yahoo.com. And whenever I try to configure the DHCP server through yast2, it gives me a bunch of errors about the DNS, as it tries to create a zone for the hosts, not that I see any way to specify the hostname/ip assignment for MACs through the yast2 UI, anyway.

Does anyone know what I'm doing wrong, or what I need to sacrifice to teh internet gawds to make this work? Thanks. Feel free to mail me answers to the usual spots.
