Ubuntu Server 8.10 DNS and DHCP Server

[danooch13]

Hello,

I am new to Linux. I am trying to setup a DNS and DHCP server on ubuntu server 8.10 which I already did. Both components work perfectly....well....perfectly separately.

My problem is that I can't get the clients that get a dhcp address from the ubuntu server register with DNS which is on the same server.

I have some static dns addresses in the server which are fine, but the regular dhcp clients will not register with dns.

Is there a way to do this?

Thanks

Anyone?

I know it has to be possible.

Read the "DYNAMIC DNS UPDATES" section in dhcpd.conf's manpage. It's all in there.

user@server:~$ man dhcpd.conf


And a suggestion: DHCP clients should not update the server, unless they can be authenticated by a good mechanism (such as Kerberos). Leave it to the DHCP server to send an authenticated DDNS update to the DNS server.

Thank you. I will attempt this in a few.

Hmm, letting the clients update the DNS is a Microsoft abomination that represents a huge security hole. It is used by MS Active Directory - they specially modified an old copy of BSD BIND8 for that.

Soooooo, my suggestion is don't do that. You can use a Samba domain controller or a NIS without having to let the clients do DNS updates.

Cheers,

Herman

LOL. I am a Microsoft admin for years, and got frustrated with it so I decided to take the switch. I guess some of my old ways carried over.
