Summary: Review Request: nss-mdns https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=172869 ------- Additional Comments From lennart@xxxxxxxxxxxxx 2007-05-24 08:13 EST ------- To say the least, Ulrich Drepper is not exactly a fan of seeing this integrated into the default Fedora install. In a recent chat on IRC that I had with him he raised a few issues he has with nss-mdns which I cannot really "fix". (As a side note: I am upstream of nss-mdns) Firstly, he believes that mDNS might be a waste of power and traffic and wants to see a big field test in Westford. I believe this is a big waste of time and resources, and is nothing I can organize from Hamburg/Germany. Also it is somewhat redundant, because Apple reports some scalability numbers for mDNS which have been generated by such a field test. (please also note that nss-mdns by itself doesn't impose any traffic on the net. Avahi does that and unless you actually look some kind of .local domain lookup nss-mdns will not add to that in any way) Secondly, Fedora uses nscd by default. Running nscd and nss-mdns together doesn't make too much sense if you use the "reload" option in nscd.conf. However that option is used by default and Ulrich appears not to be interested in finding a way to disable this option for mDNS lookups. Then, he thinks that mDNS is braindead because the cacheing protocol works differently from classic DNS. Leaves me speachless ... He apparently also thinks that Avahi is not a good thing either, but is OK with it in the default install as long as he may shut it down easily. The argument that nss-mdns is disabled at the same time as avahi is shut down he doesn't really accept, citing that the tiny bit of CPU time that is wasted when the nss-mdns module checks whether avahi is around is too much. (which btw is rather contradictorily, since nscd optimizes that away anyway) This is all very unfortunate. I am not sure what we can do about this. But as a total newcomer to Red Hat and Fedora I don't feel I am in a position to to fight this through -- at least for now. Maybe when I have a better insight into how Fedora and everything works I will give it another try. What we can do of course is getting nss-mdns into Fedora, but only as an optional package. To get this working cleanly the package would have to patch nsswitch.conf and nscd.conf on installing -- which is rather ugly. It's better than nothing, but not exactly the fullfillment of the promise of "zero configuration". -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug, or are watching the QA contact. _______________________________________________ Fedora-package-review mailing list Fedora-package-review@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-package-review
