Dns server

[prabjot52]

The DNS server configuration for CentOS and RHEL5
and the entries for the clients in its configuration files...

[Rubberman]

And your question is? FWIW, your DNS configuration is in /etc/resolv.conf

[prabjot52]

no, Basically the advanced configuration
like my server ip is 172.24.0.254
and
clients are of the series 172.24.0.x

so i want the detailed entries in the configuration files.

[Rubberman]

The only dns-related configuration file I am aware of is /etc/dnsmasq.conf for the dnsmasq server. Will work with /etc/hosts if you want, so local host names+addresses+aliases can be listed there, and DNS enquiries for local addresses will be resolved from that.

Client DNS setting are in /etc/resolv.conf. Server setting are in either /var/named/chroot/etc (chroot system), or /etc (non-chrooted system)
These are the standards, you could place them where ever you'd like but make sure that named.cond is updated to show this.

assuming u have little knowledge of dns server, as it seems u have installed it.

well to configure dns server,
the package name is cachinzones-name server,
so to start with tyoe yum install caching-name server

then there will be 2 conf files created automatically,
/etc/named/named.caching.nameserver.conf &
/etc/named.rfc1912.zones

now make a file /etc/named.conf and copy above 2 files in here...
u can use cat syntax.

now you change the conf file.
basically to start up change only the forward and reverse script..and rest u can delet..
for forward give zone as ur ip add or server name
for reverse give ur ip as (0.168.192..its e.g.)

now u need to conf database files...
/var/named/localhost.zone for forward
/var/named.local for reverse...

after that u can run

named-checkzone- <domain name> to check
and u also do chkconfig named on

and service named restart/start


for client end u need to modify /etc/resolv.conf
gine nameserver <serverip>, rest delete all, to startwith


now by cmds like :

host <servername> or <ipaddress>
nslookup "
dig "
u can run ur dns server...

i have already configured the server
i just want the mail MX entries in the dns..

[Lazydog]

You need to then setup your MX records. Something like this;

mydomain.org.   IN MX 10 mail.mydomain.org. 

or

               IN MX 10 mail.mydomain.org.

What ever you do do not forget the dot at the end.

[prabjot52]

yeah something like this

now it will create a mail box on the server
and i can mail any one using squirrel mail or simple mail.???
