dhcpd.conf : either ad-hoc -or- interim mode ?

[jenaniston]

Two DNS update schemes are currently implemented
the ad-hoc DNS update mode vs. the interim DHCP-DNS interaction draft update mode

Top line of dhcpd.conf file is to read either of these first lines . . .

ddns-update-style ad-hoc;

ddns-update-style interim;

Any pros or cons that anyway here knows of for either when setting up a dhcp server for a diskless LAN boot ?

Thank you.

You don't need dynamic DNS update for LAN booting, set "ddns-update-style none".

[jenaniston]

Well that is a answer I wouldn't have thought of . . .
but I just may be inclined to try it with an absolutely minimal boot being attempted.

As a newbie, I wonder do the now 3 different possibilities still have all the config information in the same syntax ?
(none, ad-hoc, or interim)

[markkuk]

With "none" you obviously don't need to configure any of the DDNS-related options like ddns-updates or ddns-hostname.

And here's a link in another forum . . .
"http://www.linuxquestions.org/linux/answers/Networking/DHCP_Server_Howto

With my piecing together instructions for LAN diskless boot from different sources, I'm really glad to have the wise experts as a forum resource when something comes up.

Everything you said makes good sense - as some instructions say to "disable DNS"

Thanks.
