Desktop package requiring Bind
Last modified: 2007-11-30 17:10:58 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 Description of problem: NetworkManager is explicitly specified as a package for Desktop users. It's not a good idea to force Desktop users to install and run BIND. Version-Release number of selected component (if applicable): NetworkManager-0.3.3-1.cvs20050112.1 How reproducible: Always Steps to Reproduce: 1. Try to update to the new version 2. Notice it requires caching-name-server which leads to BIND Actual Results: #rpm -e NetworkManager NetworkManager-gnome Expected Results: #rpm -Fvh NetworkManager* Additional info:
Bind is used in a caching-nameserver capability to work around glibc not noticing changes to /etc/resolv.conf quickly enough. This is not a bug.

It should be noted that while it may help some corner cases I've never seen, it breaks a lot of things now - things like "search" and "domain" from resolv.conf are now completely gone. This breaks behaviour in local networks. (in addition to the inherent evilness of having to run bind for this...)
True, but overwriting /etc/resolv.conf upon install is something that caching-nameserver package does, and /etc/resolv.conf should probably be marked %config in that package, if its not already. NetworkManager is going to blow away your /etc/resolv.conf _by design_, so its definitely not a bug in NM.
Hmm, caching-nameserver already makes /etc/named.conf %config, so that's not the issue then. In any case, this still isn't a bug since NM is designed to take over name resolution. Future versions will allow more options/configuration for name resolution however.
Using standard dhclient will get domain in /etc/resolv.conf correct, so why use another semi-broken way?
Trond, Could you paste in an example of a "correct" resolv.conf (you can x out the IP addresses if you like)? Its probably some DHCP options that we're just not writing to the resolv.conf file, but I need to know what those are. Thanks, Dan
Note, everyone, that yes bind is evil and doesn't have an extremely secure history. Its only a temporary solution until we can re-work 'lwresd' from the bind package and glue that with 'nss_lwres' to come up with a light-weight daemon that will do the same thing, but not be limited as nscd is right now. The main thing we need to be able to do is to direct queries for certain hosts to certain DNS servers, which of course nscd can't really do right now. So bind _is_ going away quite soon.
So, bind is gone for NM in FC3, but I still experience a regression : the local domain that my dhcp server sends isn't searched for hosts. Using host names like "ftp" doesn't work anymore, whereas it used to before the bind dependency was introduced. I've just checked and my /etc/resolv.conf contains the right nameserver line, but no search line.
We'll fix that and make sure that the search name is added.
