Can not do NSLOOKUP

Can not do NSLOOKUP

Post by Yuki Ari » Thu, 24 Jul 2003 11:14:25



Hi All,

I can not do nslookup in my cache only name server (Solaris 2.6). This
server refer to

another normal DNS server (Solaris 8). In the DNS server I can do reverse
lookup of

172.21.2.1. This IP is IP address of the cache only name server .

When I ping from cache only name server to another host defined in the DNS

server by using FQDN, it works.

I read some posts that it could be the reverse lookup problem but I can not

where the fault is.

Please, help me.
