hostid->hostname mapping?

2007-12-25 10:55:00

Apparently I am not the first one to have this question. I received

just about 30 replies in the first 10 minutes. Here's the short answer:

ping the broadcast address of all my networks to populate the arp table

arp -a | grep 89:dc:aa

or, if you run NIS

grep 89:dc:aa ethers (used this one)

The long answer (and better solution long term) is to run a script that

gets the hostid as well as anything else that a sysadmin would want to

know; like IP, OS version, # cpu's, amount of ram, etc... and keep this

in a database. Once the legacy systems are taken care of, start keeping

track of this info as new systems come in and you no longer have a

problem.

My appreciation to all.
