This is not the right way to go about fixing [EMAIL PROTECTED] Rather try and
get it *all* to work *out-the-box* rather than working around new
features which you do not understand!
I did some experiments last night, and I do not think this is necessary
(but could be wrong ...).
AFAICS, the only issue is that the zeroconf setup lists 127.0.0.1 as the
first nameserver, whereas it should be the last.
BTW, zeroconf, when done right, solves the problem of not being able to
resolve the local hostname.
Here is some detail from my machine when I booted it up not plugged in
(ifplugd cable detection did not work, so this is equivalent to having
it connected to a network without dhcp/bootp).
[EMAIL PROTECTED] bgmilne]# rpm -qa 'dhcp*'
dhcp-client-3.0-2pl2.3mdk
dhcp-common-3.0-2pl2.3mdk
[EMAIL PROTECTED] bgmilne]$ host `hostname`
bgmilne-thinkpad.local has address 169.254.231.85
[EMAIL PROTECTED] bgmilne]$ nslookup `hostname`
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.

So, please note that the changes I have made from the configuration made
by drakconnect/initscripts is as follows:
1)Do not specify hostname in /etc/tmdns.conf, since then tmdns will use
`hostname`. In 99% of the cases, this is what we want, since then GNOME
will always be happy.
2)Set HOSTNAME to be a real name in /etc/sysconfig/network, and use the
same value as DHCP_HOSTNAME in /etc/sysconfig/network-scripts/ifcfg-eth0
[EMAIL PROTECTED] bgmilne]# grep HOSTNAME /etc/sysconfig/network
HOSTNAME=bgmilne-thinkpad
[EMAIL PROTECTED] bgmilne]# grep HOSTNAME
/etc/sysconfig/network-scripts/ifcfg-eth0
NEEDHOSTNAME=yes
DHCP_HOSTNAME=bgmilne-thinkpad
3)Ensure 127.0.0.1 is the last nameserver listed in /etc/resolv.conf.
According to /usr/share/doc/tmdns-0.1/README, 127.0.0.1 can be listed
first, but then, now that I am connected to a real network (with dns and
dhcp), I get:
[EMAIL PROTECTED] bgmilne]# cat /etc/resolv.conf
search cae.co.za local
nameserver 127.0.0.1
nameserver 146.232.174.17
nameserver 146.232.128.1
[EMAIL PROTECTED] bgmilne]# nslookup `hostname` -sil
Server: 127.0.0.1
Address: 127.0.0.1#53
** server can't find bgmilne-thinkpad.cae.co.za: SERVFAIL
Then, putting 127.0.0.1 last:
[EMAIL PROTECTED] bgmilne]# cat /etc/resolv.conf
search cae.co.za local
nameserver 146.232.174.17
nameserver 146.232.128.1
nameserver 127.0.0.1
[EMAIL PROTECTED] bgmilne]# nslookup `hostname` -sil
Server: 146.232.174.17
Address: 146.232.174.17#53
Name: bgmilne-thinkpad.cae.co.za
Address: 146.232.174.230
146.232.174.17 and 146.232.128.1 are the DNS servers supplied by the
DHCP server. Ideally, they should be removed from /etc/resolv.conf when
the interface is taken down ...
