Following is list of steps when configuring Solaris 10 system as a DNS Cache server. (Hostname and IP addresses just for an illustration. Its not real but db.cache file. Its hold real ROOT.SERVERS information)
1. Update Solaris 10 DNS patch.
Patch-ID# 119783-08: SunOS 5.10; bind patch (Note: current patch release: 119783-10)
2. Create and check following configuration files
- Check for /etc/hosts file
- Create and edit DNS configuration file; /etc/named.conf
- Create domain run directory; e.g. /var/opt/named
root@prambanan: mkdir /var/opt
root@prambanan: mkdir /var/opt/named
- Obtain a copy of root name (root hints) file; /var/opt/named/db.cache
- Create and edit reverse zone file; /var/opt/named/db.local
- Create and edit local zone configuration file; /var/opt/named/candi.hosts
root@prambaban: # cat /etc/hostsroot@prambanan: mkdir /var/opt/named
- Obtain a copy of root name (root hints) file; /var/opt/named/db.cache
- Create and edit reverse zone file; /var/opt/named/db.local
- Create and edit local zone configuration file; /var/opt/named/candi.hosts

3. Start the DNS Server
root@prambanan: # svcadm enable /network/dns/server
4. Check /var/adm/messages file for a successful named (BIND) startup
root@prambanan: # tail /var/adm/messages
Jun 12 10:25:30 prambanan named [1916]: [ID 767358 daemon.notice] starting BIND 9.3..5-P1
Jun 12 10:25:30 prambanan named [1916]: [ID 767358 daemon.notice] command channel istening on 127.0.0.1#953
After up and running for long time, the cached may be huge, and may need to refresh. Use procedure below when refreshing the cache or restarting BIND:
root@prambanan: # svcadm disable /network/dns/server
root@prambanan: # svcadm enable /network/dns/server
