[K12OSN] OT: /etc/hosts autoupdate

[Paul VanGundy]

All,

Thanks for the advice. We currently have an Active Directory infrastructure
in our district. Those that have an AD infrastructure know that the ADS
needs DNS. So we have DNS running on the server that has Active Directory
installed and a backup DNS it replicates with on a Windows 2000 Advanced
Server. Here are my next questions:

1. Can I have Bind be a secondary DNS and replicate from the primary DNS
that is installed on the Active Directory server? 

2. How will this effect my thin clients?

3. What's the difference between BIND and BIND-CHROOT?

Thanks again.

-Paul

I don't know about software to update /etc/hosts, but this feature IS
available in DNS.

Basically, you:
1) tell DHCP what the ddns-update domain is, and where the server is (and,
possibly, a cryptographic key to authenticate the DHCP server to
DNS)
2) tell the name server to accept updates from the DHCP server (make sure
name server can write to its data directory (/var/named, or
/var/named/chroot/var/named if bind-chroot is installed).

After that, client names should go into forward and reverse DNS zones once
they get an IP address from DHCP.
