[Pkg-utopia-maintainers] Bug#595330: avahi-daemon: iptables --list pausing several seconds before listing an a 192.168.1.0/24 entry.

[Kaz Kylheku]

Package: avahi-daemon
Version: 0.6.23-3lenny1
Severity: normal
File: avahi-daemon


I was wondering why in the iptables command, reverse lookup on my local
network was taking so long. It works fast with nslookup. My DNS server
is the dnsmasq running on the Linksys WRT54GL (Tomato firmware). Of course
it knows the 192.168 network!

I ran an strace and discovered that iptables is talking to some Unix
domain socket to some avahi daemon, which turns out to be some
non-invention related to some idiotic idea from Apple.

I promptly ran "apt remove avahi-daemon".

Problem went away; iptables listing now instant.

WTF is this good for, why is it installed by default, and why does it choke
on things that your regular DNS doesn't?
