nslookup

Hi all....I recently tried nslookup on all my machine names/IPs. If I type in the machine name, it comes back with the IP. If I type in the IP, it comes back with 'no hostname infotmation available on ### IP'. Is it the lookup order of my table? I can't even do my brrestores until I get this resolved. No pun intended.

Check the /etc/nsswitch.conf file. See what order the lookups is happening and adjust if necessary.

Jennifer:

Along the lines Rick suggested; run nslookup and type "policy". This will give you the policy from the switch configuration file.

I looked up my nsswitch.conf file and it does not appear to need adjusting. Anything else?

Jennifer, does your DNS server provide reverse-DNS lookups?

I can perform reverse lookups on all servers except for one.

If you can do reverse lookups on all servers but one, check the DNS entry for that server. Do you have the ending period (.) for the entry?

Our lookup goes off of our named.data file. THere are no ending .'s.

For the reverse lookups you would need PTR records. These end in the (.)

Here's the deal...the node name was missing in the reverse DNS file....

THanks for everyone's input.
