resolv.conf wont stay on reboot [message #30316] Wed, 21 May 2008 03:07 Go to next message

Running CentOS 5.1 in a VE and when the OS is rebooted the contents of the resolv.conf file are overwritten with what I believe are the DNS server IPs of the HN.

Why is this happening and how can I stop it?

I want to stop having to manually re-add the correct IP entries after every reboot!

I am the end user of the VE and not the HN admin.

Hi,

1. You can ask HN admin to set inside your VE the correct nameserver. (via --nameserver option)

2. If it's impossible try to add appropriate commands for example in /etc/rc.local file to change /etc/resolv.conf file.

Are you using dhcp client inside VE?
If using http://sourceforge.net/projects/dhcpv6/
or http://www.isc.org/products/DHCP
try tweaking
prepend domain-name-servers dnsrv2,dnssrv2,...
inside /etc/dhclient-eth?.conf

IF using http://roy.marples.name/dhcpcd
add nodns option to dhcpcd daemon
