Dear All,
I have a REDHAT box running bind and been working fine for last few months. this server was hosting my other other local domains also which were all
workin fine
i installed a new redhat machine with bind to be a secondary or slave
named server a week ago as per the documentation .
   so if my primary server goes down  all my clients and the inrternet
users can still access my my web sites.
Now when i restart my primary i c the zones gettin transferred to my
secondary DNS which i newly setup and when i do a nslookup goin into the
server for internet sites ex: www.yahoo.com it does not resolve them
but the sites hosted in my netwrok im able to resolve them fine here the details my master name server .. ns1.kmun.gov.kw ---- IP
62.150.152.1
   slave server which new installed   .. ns2.kmun.gov.kw -------  IP
62.150.152.2

Looks like 62.150.152.2 is set with recursion off. That means it will only answer for zones it is authoritative for. If you want it to be a server for others to query, set recursion to yes. You are using Bind 9 (v9.3.4) so you can set an access list for allow-recursion.

Something like:

acl allowed-nets { x.x.x.0/24; y.y.200.0/21; };

options {
  recursion yes;
  allow-recursion { allowed-nets; };
};

The allow-recursion is optional but without it, sooner or later, some dickhead script kiddie will try a DOS on you.

  if i go to server ns1.kmun.gov.kw or the ip i can resolve both the
internet sites as well as my local domain ...
appreciate ur help thnks and Regards simon --------------------------------- Pinpoint customers who are looking for what you sell.
