Uninstalling caching-nameserver

[bubarooni]

Hi All,

Somehow during my RHEL 5 installation, I seem to have installed a caching-nameserver on my machine and can't get bind to start.

How can I uninstall this caching-nameserver?

Thanks In Advance

How about:

yum remove caching-nameserver

or just stopping and disabling the service?

i tried the uninstall with no success. i'll try the disbale option.

on the way home last night i thought of something else that might be causing the problem too.

i have an existing exchange server that i'm getting ready to replace with this new Zimbra server. both boxes sit behind a firewall. i set up a test box a few months ago with split dns and using mydomainname.net instead of mydomainname.com and it works great.

my plan was to get the new box all setup like i did the test box and then simply change the static route command on the firewall to point to the new zimbra server instead of the exchange server when the big day to switch arrived.

since the new zimbra server is not using the outside ip address of my mx record which is still currently pointing to the exchange server, would that prevent the named service from starting?

Can you telnet to port 53 on your server? What error message are you getting when you try to start BIND?

i'm supposing there that if the zimbra box is appearing on the internet with an ip of 1.1.1.10 and the actual mx record for my domain is 1.1.1.9, named service is not resolving the ip to the domain name and is refusing to start.

would that be corrent?

telnet to port 23 or 53? i'll post the fail message as soon as i get into the office.

Telnet to port 53 - that's what a nameserver listens on.

Are you sure the caching name server is just not BIND setup to use a forwarder? It may be setup to use recursion (similar to using a forwarder). Can you look at the services running on your system to see if BIND is already running?

I could be wrong since I use SuSE, but the only name server I am aware of is BIND.

yep. the telnet to port 53 returned a 'connect failed' from a dos prompt on my workstation.

Do you actually have BIND installed - 'yum info bind' does it show as installed? So what command are you using to start BIND and what error, if any, does it return?

Have you also stopped your firewall and SElinux? What happens if you go to your server and try the telnet to port 53 again?
