DNS Revisited

DNS

We have configured simple DNS to answer queries about our domain.

• How does dns work again?
• As of now, our DNS will not do lookups for us.

Steps to configure

• install bind9 as necessary
• modify /etc/bind/named.conf.options to allow hosts to query us.
• configure for query logging in the same file
• Restart bind9
• Test!
• Repeat for each lookup server

Dig it!

• Dig from localhost for non-authoritative data.
• Dig from your other network systems for non-authoritative data.
• Dig from outside your network for non-authoritative data.
• Dig from outside your network for authoritative data.
