-----BEGIN PGP SIGNED MESSAGE----- Is this the thing that tells the Linux box to attempt to get itself inserted into the DNS for the domain?
I've got a RH 8 box doing DHCP serving and DNS serving for my local network. The DNS is also set up to cache and forward queries for hosts outside my network.
When a Windows box (2000, NT, ME, or XP) comes along, it gets assigned an IP address by DHCP. It also shows up with its IP address in the DNS for the local network.
When a RH 8 box comes along, it gets assigned an IP address by DHCP. However, it does NOT show up in DNS.
This drove me nuts for a while, and I spent a lot of time looking through documentation and web references. I finally "solved" the problem by setting all of the Linux boxes to have fixed IP addresses, and manually added them to the DNS server. I am not happy with this "solution", though. Any fix to get Linux boxes with floating DHCP assigned IP addresses to appear in the DNS tables would be appreciated.
Apparently this can be done by BIND - although I've never gotten it to work.
Also, there's another DNS daemon out there (dnsjb or something like that), which is apparently smaller than named AND supports dynamic updating through DHCP, however, I've never tried it, because there wasn't enough testimony to say it was good, great or even secure.
There's also scripts available on the web which scan the leases file and update DNS accordingly - I also have never gotten THAT to work.
Part of the problem is I don't understand enough about BIND. The concept of creating different 'zones' and stuff is all beyond me. I'm using it as a caching nameserver only and that seems OK. I'm way too good at breaking things to risk screwing things up.
If anyone has gotten a nice easy way of updating the DNS via DHCP, and would like to share, I'm all ears.
