[gentoo-user] Painted into a corner: avahi and mDNSResponder

[gentoo-user] Painted into a corner: avahi and mDNSResponder

[Alan E. Davis]

Almost perpetually, the following packages or their versions are
blocking.  I have run emerge -e system several times.  Some other
problems were cleared up, and this
avahi--mDNSResponder/mdnsresponder-compat whatever it all is, just
keeps coming back even when solved by some skullduggery.  I've removed
both of them at one time or another.

[blocks B     ] net-dns/avahi ("net-dns/avahi" is blocking
net-misc/mDNSResponder-107.6-r5)

[blocks B     ] net-misc/mDNSResponder ("net-misc/mDNSResponder" is
blocking net-dns/avahi-0.6.23)

I guess the problem is that I am running gnome and also have two or
three different versions/slots of kde installed.  I suppose, then,
it's remarkable that only these blocks are showing up?

Can someone lend a hand on this?  Anything I do is little more than
blind tinkering.

Alan

Play around with your USE flags, you'll get it working eventually
(that's what I did).

set the avahi useflag, unmerge mdnsresponder, emerge avahi.

That looks familiar. I remember similar deep blocks myself - it was nasty at 
the time.

For the OP's benefit, here's a high level summary of what is going on:

Avahi and mDNSResponder implement a system called ZeroConf, first designed by 
Apple. It's a way for machines on a network to find each other and what 
network features they support. These systems are quite low-level so 
unfortunately the implementations are often incompatible.

By and large you will find that Gnome stuff supports Avahi and KDE stuff 
supports mDNSResponder, so the only way out of this mess is often extensive 
use of 'equery hasuse', 'equery depends' and 'emerge -pvt' so see what pulls 
in what. But first you should research what these things are so you can make 
intelligent decisions about what to include and what to drop. The thing that 
cleared it up for me was an interview with the KDE team lead responsible for 
these features - Google will find it for you.

Personally, I find these things more trouble than they are worth. They seem to 
be designed for the "Apple Generation User" (whatever that is), and I have no 
use for that on the networks I work on. ZeroConf is not necessarily something 
you have to have installed...

IIRC mdnsresponder-compat USE flags allows use of avahi in KDE (3).

I believe you are correct:

alan@nazgul ~ $ grep mdns /var/portage/profiles/use.*
/var/portage/profiles/use.local.desc:net-dns/avahi:mdnsresponder-compat - 
Enable compat libraries for mDNSResponder

just grep for avahi in /usr/portage/kde-base ....
