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.
