Forced to use FQDN on LAN

Hi,

I have a LAN of 3 computers all running RedHat Linux 7.1. The three computers are named mach1, mach2, and mach3, and the domain is log.cabin. mach1 is the "main" machine and runs Apache, bind, and a buch of other currently irrelevant daemons.

mach1 has a firewall, but it doesn't block anything from the local net. I've set up the bind config files to be authoritative for the log.cabin zone.

If I run 'host mach1' from any of the 3 machines, I get an immediate answer. However, if I 'dig mach1' from any machine (including mach1), it times out. 'dig mach1.log.cabin' works fine. When I ssh or telnet to mach1, I have to specify the FQDN or it takes a very long time.

The funny thing is, I can run 'dig mach2' or 'dig mach3', and get immediate responses. Also, the delay does not exist when I am connected to my ISP (dialup modem...don't use their nameservers).

I can provide any config files necessary, I just didn't want to if it wasn't necessary. Anyone have any ideas?

Thanks,
Ben

Show us your zone file, named.conf, resolv.conf and /etc/hosts file.

Here are the files. I would have attached them, but it doesn't appear that more than one file can be attached. They all come from mach1. mach2 and mach3's resolv.conf and hosts files look pretty much the same. I don't recall modifying the other zone files (mentioned in named.conf), but I can post them also if needed. I didn't figure they would be relevant since log.cabin is my zone of trouble.




One other thing--here are the IP numbers for my machines:


mach1 == 192.168.1.40


mach2 == 192.168.1.41 and 192.168.2.1


mach3 == 192.168.2.2





(I don't have a hub so mach2 has 2 ethernet cards in it, and serves as a router between the two networks.)





Grateful for any clues,


Ben
