Hello
A few (or a lot) of us supports larger corporate networks. I would like know your opinion/solution based on CentOS. No Win auto/dynamic/smart (WI|D)NS/DHCP
How do you manage DNS&DHCP (the informations filled in, not the server software) for hundreds or thousands of computers?
For our network, just now we use homebrewed scripts, but they are getting unsufficient (cca. 700 machines).
I found this:
http://sauron.jyu.fi/ = Sauron - A Free DNS & DHCP Management System
What are references for that? Good, bad, sufficient? Do you use something similar?

There is NO ^^^^^^^^^^^^^^^
bind and dhcpd support dynamic dns.
OK, when I resig on managing DNS and I will use !bind and dhcpd support dynamic dns! I stil need an tool for managing DHCP entries.

To elaborate a little:
you can edit the file /etc/dhcpd.conf
and have entries like this:
host johnny1 { option host-name "johnny1.home.local"; hardware ethernet 00:a0:cc:62:6d:2c; fixed-address 192.168.0.16; }
----------- What else do you need to manage via a tool?
Here is a simple, but fully working file:
vi?
I use it now with several scripts ...

As I wrote, I allredy manage network with cca 700 computers with running DNS/DHCP .
Just now. 20 locations 9 DNS domains 5 organizations
and growing ;-)
What else do you need to manage via a tool?
- Web interface (there is several admins not only me) - comfort ;-) imagine adding an IP/name by one action instead of adding to DHCP, primary DNS and at least reverse DNS "clases" of computers "defaults" for location/domain ...
- several checkings - unique name/IP/MAC domain/location (which are complicated but posible to write in bash/perl)
Here is a simple, but fully working file:
and
option time-servers xxx.xxx.cz; next-server XYZ ; filename "/tftpboot/boot.0";
....

What people would likely want is something that presents a single screen form where you enter the name, mac address, ip and optional aliases, and it writes the dns forward zone A record and optional CNAMEs, the dns reverse zone PTR record, and the dhcp fixed-address entry, and restarts the appropriate daemons to activate the entries. With reasonable syntax and duplicate checking, of course...

try dhcpdman.sourceforge.net or config-dhcpd.sourceforge.net?

ISC bind and ISC dhcpd work well together to do ddns updates. As a management tool, I recommend Webmin http://www.webmin.com which will do a lot more than DNS/DHCP for you.

I think he was looking more for a distributed LAN/management solution.
In reality, I do have to say that ISC's piecemeal DHCP and DNS servers were really designed for the Internet, and not a management LAN. Which is why I think there really needs to be an integrated, private LAN-only combinational layer 2 + layer 3 name services daemon.
So far, the only ones I've seen are either ADS-integrated, proprietary or scripts/hacks around ISC DHCP+DNS. The few proprietary ones I've seen look pretty good though, but I've never deployed them.
HI!
Not sure if this is what you are looking for, but it may be of interest:

The problem with automating DHCP entries, from my view in the cheap seats, is that policies tend to differ widely enough from site to site to make generalizations difficult. Even within a site, it can get dicey. I've managed networks, for instance, where
a. some hosts get a static address on their "home" subnet (typically, the one available at the user's desk) but are able to get a dynamic address on other subnets, like those available in conference rooms.
b. some hosts only get dynamically allocated addresses, and only on a limited set of subnets.
c. some hosts, mostly rack-mount machines, are treated like hosts in the first group above, but they get long leases on the home subnet and short leases on testing nets.
d. some hosts, these of the dying breed of stationary desktop workstations, actually lived only on one subnet.
As you know, only the last type had a single host entry in the final config files; the rest required at least two. We tried really hard to script all these policies, but our users were so creative at finding new DHCP niches where their machines "had" to live.
In the end, vi[m] was the best tool, because it was just too hard (for us, anyway) to abstract DHCP usage policies well enough to encapusate them in scripts. Plus, in the end, the configuration entries didn't even resemble a DHCP config file, so all admins had to know their way around both production DHCP config files *and* our funky pre-production script-friendly configs. Feh! :-)

YES, this and http://sauron.jyu.fi/
are may favorites, will look at them ...
