Hi, Sorry for the beginners question, but how does my DNS server get to know about leased DHCP IP <-> hostname information? If the IP address changes from lease to lease the DNS has to be informed by that. I looked into some manpages and howtos but did not find the information. Thank you very much for a hint and best regards, Rainer

Asking beginners question is usually not the problem - offtopic questions are a different story - this is not really security-related :)

It doesn't, at least not automatically.

You need to create some script magic or use one of these: Dynamic DHCP to DNS http://www.heronforge.net/~stephen/DHCP-DNS/dhcp-dns.html dhcp_dns http://www.sector13.org/kazin/files/dhcp_dns/ Dynamic DNS http://freetings.com/linux/dydns/index.php3 Bye, LenZ -- ------------------------------------------------------------------ Lenz Grimmer SuSE GmbH mailto:grimmer@suse.de Schanzaeckerstr. 10 http://www.suse.de/~grimmer/ 90443 Nuernberg, Germany Power is an illusion; only stupidity is real.
Look into the dynamic dns information on http://www.isc.org/products/DHCP/. However, if you don't know how to do dns, I wouldn't suggest diving into this, it can get *very* frustrating *very* quickly. It is possible to do with just bind and isc dhcp though, no other third party software is needed. -miah On Fri, Nov 17, 2000 at 04:01:15PM +0100, suse@diplan.de wrote:

Dynamic DNS is actually not to difficult, (although it originally took me a day to get it all working) If you are running SuSE, then all you should have to do is download the latest beta copy of DHCPD from ISC and recompile with an extra option. (something like --with-nsupdate from memory) Then you will need to allow updates from your DHCP server in named.conf. If you are running RedCrap then you will also have to recompile BIND do enable support for Dynamic Updates in Bind. (Yet another example of SuSE have the "RIGHT" compile defaults, whcih is one of the reasons I use suse so extensively on my networks.) Cheers Nix At 09:42 AM 17/11/2000 -0800, you wrote:

The DNS related manpage would have sufficed. :) Try something like "man named.conf" and search for "update". If in doubt as to where find DNS info, try "locate DNS" or "locate named" or something like "rpm -ql -f `which named`". virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
