hi all,

i want to install dns in my pc. can anyone guide me all configurations in a broad way.

thanks in advance.

regards,
srini.

You can use yum to install the RHEL5 BIND packages.

The packages I'm running on my RHEL5 DNS servers are:
bind-libs
bind-utils
bind
system-config-bind
bind-chroot

Running "yum install <package>" for those packages will install them. (Actually if you just run it on bind-chroot it will likely install the others as dependencies - any it doesn't you can install separately.)

The bind-chroot puts BIND into a jailed configuration to prevent anyone from hacking your DNS and getting out to the rest of the server. (Though if they hack your DNS they may not need to get out.) The default chroot directory it creates is /var/named/chroot.

The main configuration files for BIND are in /etc (named.conf and others) and /var/named (zone files). In the bind-chroot environment these become /var/named/chroot/etc and /var/named/chroot/var/named respectively.

The RHEL BIND documentation is at:
http://www.redhat.com/docs/en-US/Red...e/ch-bind.html

iirc, you need the caching-nameserver pkg to get the named.ca aka root.hints file ie list of world DNS root servers.

Or get the root servers info yourself the standard BIND way:
dig ns . @a.root-servers.net >/var/named/chroot/var/named/named.ca

hi

i install bind,bind-utils,bind-libs and bind-chroot packages in rhel5
but i could not find named.conf in /etc.

what could be the problem.can anyone guide me?


thanks,
srini

If you open GUI system->admin->server->dns it will make you file /var/named/chroot/etc/named.conf wich is the file you should edit on chroot environment.

See post #2; bind is chrooted
