1. DHCP, DNS, WINS, dynamic DNS, other questions
Want to set up DHCP/DNS on an internal TCPIP network with a mixture
NT4/SP5, W9x, and linux network. Trick is that many of the name/ip
assignments can be dynamic. My understanding is that DNS is a static
arrangement. How can one provide for the dynamic nature of the
name/ip assignments.
Normally, one would use WINS (good, bad, indifferent) but that doesn't
help the linux boxes (none of them has, or needs, samba). Is there a
more generic, standard way of providing a 'dynamic' DNS ?
The network is a mix of NT4SP5 desktops, a couple of NT Servers
running Oracle, SQL Server, and file/print services, and some linux
boxes doing various things such as DHCP, firewall duty, apache, and
some other things. There are also a couple of W9x boxes sitting
around, mostly with USB stuff hooked to them. All are networked w/
TCPIP on the 192.168.3.x address space.
I went ahead and set up the DHCP on two low-end linux boxes that were
laying around. I split the address space between 3.50 - 3.125 on one,
and then 3.126 - 3.200 on the other to provide redundancy.
I have not set up bind on these boxes until I figure out how to handle
the dynamic DNS issue.
In NT there can be a link between DNS and WINS, but I don't really
want to set up the DHCP /DNS/WINS arrangement on any of our existing
NT server boxes; they're twitchy enough as it is, and the two boxes
mentioned earlier aren't really upscale enough to put NT on, anyway.
hm. So, to summarize the rambling:
1. What 'generic', standard (simple, easily maintained, even
automatic) ways are there to do dynamic name services tied with a DHCP
services.
2. Can these solutions be easily implemented on linux or free unix
boxes?
