UNIX for Dummies Questions & Answers

Hi all,

I am a newbie of setting up DNS server. Everything went fine except one thing.

When I do "nslookup", my server name apears as "my_server.1.131.10.in-addr.arpa" rather than "my_server.my_domian.com" on my clients. Do you know how to fix it? Thanks.

Could be in a few places - first thing to do is let us know what OS and version.
Then I would suggest looking at your resolv.conf file - it may simple be a mistake in there.

If not, do the nslookup command
look up my_server.1.131.10.in-addr.arpa
then look up the IP it gave you - does it come back with my_server.1.131.10.in-addr.arpa or with the your-server.your-domain.com?
Then set the type to ptr ( set type=ptr) - put in the same IP as last time - does it resolve it correctly?

And post what verion of DNS you are using.

My first guess would be that your reverse zone file is incorrectly formatted.

If you are using bind, make sure you have ended the hostname with a '.' If not you will get exactly what you are seeing.
