Something changed in the way dhcpd operates that causes a
new nameserver query that 5.1 didn't do. I run diald to
demand diald my internet connection on my home machine,
and also run dhcpd to allow a laptop to get configured for
the home environment (using a Netgear ethernet card for the
home network). Under 5.1, if I put all hostnames mentioned
in the dhcpd.conf file in /etc/hosts, and set the query
to look at files before dns, it would not do an external
nameserver query when the dhcpd server started. Now with
5.2, I see the following queries when dhcpd starts:
(220.127.116.11 is the IP address of the host dhcpd is
running on). Obviously, I should set up reverse mapping
on my local nameserver for addresses it knows about, but it
is odd that dhcpd now does this query when it previously
didn't do it before.
re-assigned to Erik, who owns this package. :)
Further debugging shows that its not the dhcpd server that seems
to be causing the network traffic, but the caching name server that
is (dhcpd just happens to be executing when the modem starts dialing).
I have worked around the problem by not bringing up the caching name
server until the modem is brought up the first time.
The additional information on this implies that it's not a bug
in dhcpd after all, so I don't have to fix anything :->
