DNS setup help

tsaravan · 10-20-2008, 12:13 AM

Hi,

i want to setup dns in fedora 9 to resolve private ip as mentioned below:

cms.eri.blr.in 192.168.0.10
km.eri.blr.in 192.168.0.11
pms.eri.blr.in 192.168.0.12
ess.eri.blr.in 192.168.0.13

The same system will be running squid proxy server and if user wants to access Internet the name resolution should be through ISP's dns server.

right now i have created hosts file and placed in the users system for name resolution of private IPs. But if any change in the IP, i have edit hosts file of each and every system which is a tedious process.

I need complete setup guide as per the above requirement and it would be nice if configured file is provided with explanation for me to understand.

regards,

Saravana.

Maybe you should set up a local DNS server?

just set up bind9 and add an entry for those domains like you would any other. Never done this before but i would do something like this (no idea if it work though)

Code:

@       IN      SOA     hostname.domain.com. domains.domain.com. (
                        1181707685
                        10800
                        3600
                        604800
                        38400 )
cms.eri.blr.in.  IN      A        192.168.0.10
km.eri.blr.in.  IN      A        192.168.0.11
pms.eri.blr.in.  IN      A        192.168.0.12
ess.eri.blr.in.  IN      A        192.168.0.13

But this might not be the exact way to do it. you should consult the bind man pages.

Thank you for your reply.

I just want to know what is hostname.domain.com. domains.domain.com. Should i enter as it is.

Further, if user want to access Internet, then where and how to configure.

regards,

T. Saravana.

hostname.domain.com = the fully-qualified name of your primary DNS server. It should be something like "ns1.eri.blr.in.".

domains.domain.com = domains@domain.com--this is the e-mail address of the DNS admin. It should be something like "hostmaster.eri.blr.in.".

You need to do some basic reading. Start here http://www.isc.org/index.pl

Also, i may be wrong here, but if you just add the entries above to a /etc/host file on one server and then set that server as the primary DNS for all the others it might also do the trick.

Not sure if this will work 100% or if there might be another step to it as i have never done this.

No, it won't. Why would you bother to post about something you have no experience with?
