Hi,
probably someone had similar problem before, but I decided to describe it.

Few days ago I suddenly discovered that my resvol.conf is changed , it
looks likt that:

domain darkorb.net
search darkorb.net
nameserver 216.118.116.101
nameserver 66.197.217.12
nameserver 66.246.41.14
nameserver 66.197.217.11
nameserver 66.96.193.2
nameserver 66.96.194.2

/var/log/messages says that:
Oct 31 09:41:28 ptssa nscd: nscd shutdown failed

resolv.conf had the same modify date.

I'm using Red Hat 9, with the newest bind avaiable on the redhat:
[root@rumbrak log]# named -v
BIND 9.2.1

[root@rumbrak root]# rpm -qi bind
Name        : bind                         Relocations: (not relocateable)
Version     : 9.2.1                             Vendor: Red Hat, Inc.
Release     : 16


[root@rumbrak root]# netstat -ln
