Hi,
This has really got me stumped. I'm trying to setup a small (home) network
that connects to the internet via modem (ppp0). I would like for guests to
be able to access this network without any/much setup so I am running a
dhcp server that should also update the DNS so that others, and especially
the main server can access by name.
Seems pretty straight forward doesn't it? And it works except for one small
problem. DNS queries not using the FQDN fail while queries using the FQDN
succeed. IOW dig host.xxx.xxx is ok but dig host is not found. This causes
some big delays during various operations on the clients as their queries
always timeout first.
I'm hoping it's just one of those little details that I missed because of
the late hour.....
Here's the relevant files and info. I've changed lot's of stuff trying to
track this down so you may see some odd entries here and there that I
forgot to remove. Also, some names/addresses have been obviously disguised.
This is Fedora Core 3 (nash) on a Pentium4.
The dhcp and dns servers run on center.frank.home which is at 192.168.0.5.
There is a laptop (laptop-wlan) connected at 192.168.0.9.
From the laptop I get these responses (the log output follows). It's similar
when I use the laptop's hostname.
