First of all, domainname refers only to the NIS domainname not the DNS domainname. the domainname I'm trying to affect here is for DNS and it's referred to by RH as dnsdomainname. I've tried altering the DOMAINNAME var in /etc/sysconfig/network and verious permutations and have yet to make any change to dnsdomainname. the docs suggest that the dnsdomainname is obtained from /etc/hosts, and failing that, from /etc/resolv.conf. However, I cannot seem to affect any change despite what I put in /etc/resolv.conf. Usually, a RH server is able to determine this itself 'automagically', probably from a reverse lookup of the IP address. However, when the 'magic' fails, there doesn't appear to be any way to manually tweak this dial.

The simplest way is to tell the client to use DNS settings provided by DHCP server (PEERDNS=yes) and let the DHCP server provide all the required settings. --Saurabh From balazs at fmnet.hu Wed Dec 14 02:37:20 2005 From: balazs at fmnet.hu (Honti =?utf-8?B?QmFsw6F6cw==?=) Date: Wed, 14 Dec 2005 03:37:20 +0100 Subject: RHEL4 freeze In-Reply-To: <5ea165840512131810t34969796m5abb4c5d89bce67d@mail.gmail.com> References: <5ea165840512131810t34969796m5abb4c5d89bce67d@mail.gmail.com> Message-ID: Hello!

We tried, and it doesn't freeze even with 1 cpuburn on, with all its devices inside when I boot Debian, with a non-SMP kernel, from IDE harddisk. So I begin to think it's maybe an RHEL hardware incompatibility issue. And no real system failure. Could I be right? Or need some new kernel or module? Maybe anyone having a similar machine?
