I comment off the 'auto eth0' in /etc/network/interfaces, and then:
aptitude install ifplugd resolvconf dnsmasq
My /etc/default/ifplugd looks like this:
ARGS="-q -f -u0 -d10 -w -I"
# Note: Use 'localise-queries' in dnsmasq.conf
127.0.0.1 journeyhawk.karlheg.net journeyhawk
127.0.0.1 localhost.karlheg.net localhost
192.168.XXX.XXX journeyhawk.karlheg.net journeyhawk
... and I've added the 'localise-queries' (watch the spelling; s not z)
option to 'dnsmasq.conf', so that when a DNS query comes in over
127.0.0.1, it get answered with that entry. When it comes in over any
other interface, it should get the other entry.
My WRT54G (running OpenWRT) has dnsmasq on it also, and is my LAN DNS
server. I've a static intra-net IP for my laptop's MAC. For
out-of-the-house, I can use dyndns if I need it, otherwise, anonymous
works just fine.
send host-name "journeyhawk";
... in /etc/dhcp3/dhclient.conf, so hopefully I'll be given a name on a
LAN that supports dynamic DNS with DHCP, if I jack into a LAN or WLAN
that has that feature. (dnsmasq does it, afaik).
