avaih daemon ports

I'm running linux (Kubuntu 7.04) and my PC network has been work
fine until today. Today, my internet access broke. I checked
ifconfig and found that my ethernet port eth0 is running avahi-deamon
and the address is 169.254.6.95. Before today, as far as I know
the IP address assigned by dhcp was 192.168.2.100.

I checked my router and legal ports on my LAN are 192.168.2.100
through 192.168.2.149. To get my network working again it would
seem that I would have to configure avahi-daemon to assign a
port in the same range that the router is using. I have taken
a quick look at the avahi documentation, but I have not figured
out how to set the range.

Does anyone know if I can configure avahi to a fixed range, and
if so, how can I do that?

Thank you in advance.

You should be able to disable the avahi-deamon and still connect
to the router. You can use dhcp or set your nic as static.

My modem/router does dhcp assignments. I chose to set my desktop as
static (192.168.1.131), dns servers are set to opendns servers
(208.67.222.222 208.67.220.220) and have no network problems.

That way if black hats crack my router, I know I will still have valid
DNS servers and my lan ip addy does not change when the router is dinked up.

First, a bit of terminology. IP addresses and ports are two different
things. A port is a single number from 0 to 65535. In a network with
a DHCP server you don't need to run avahi-daemon at all, but it's also
possible to have both avahi and DHCP. The avahi protocol always uses
IP addresses in the 169.254 range. If you don't get an address from
your router, there may be a problem with your DHCP client software.

I was able to disable zeroconf and then set my port address
to a fixed value. All is well now. Thank you for the input.
All of you!
