 Posted: Thu May 12, 2005 7:01 pm Post subject: Automatic DNS registration/discovery. |
 |
|
I'm currently working on building my home network.
I want to use mostly dynamic IPs from my DHCP server, but I would like all my machines to register on the DNS server when boot up.
Some idea of my network topo
| Code: |
Yosho = 192.168.0.1 (This is my fixed gateway and router to the internet. It as my firewall on it)
Mioshi = 192.168.0.5 (This is my DHCP and DNS server among other things. )
Washu = 192.168.0.2 (this is my HTTP web server and may eventualy be turned into the DHCP and DNS server as I turn load up on mioshi)
|
| Code: |
Tenchi = this is my wireless laptop
Ryoko = This is my desktop
Sasami = This is another PC on the network
x-box = my xbox
|
I would like the 3 PCs to get IPs dynamicaly from the DHCP but for the name to always point to the right computer. So if I do ping ryoko it will point to the right IP address. They use a mix of OS (linux and windows mostly)
I was wondering if anyone could point me to the right direction. I installed djbdns but am not sure where to go from there

Unless djbdns has been heavily patched recently I don't believe it supports dynamic DNS of any sort. You'll have to go with Bind to get that functionality. I see some Perl scripts that add some of the functionality... but it all looks a bit goofy.
However if you just want this to work for a few machines I'd go with static entries in your DHCP config. Setup static entries for your servers based off their MAC address. Use IP's that aren't going to by in your regular DHCP range. The servers still get their IP by DHCP, but it's always the same IP due to the static entry so you can hard code it into DNS. Then set a normal DHCP range for unknown MAC addresses from .50 on up. That way people can bring their laptops over and have no issues.

The solution I have right now is to have static entries in DHCP and hosts file, but I'd like something more professional.
The reason behind it is more educational then practical. My network is plenty small to be managed on a "per machine" basis, but I want to learn how to get it to do that.
Guess I have to learn BIND then.

Maybe dnsmasq is what you want and enough for what you need
| Quote: | Dnsmasq accepts DNS queries and either answers them from a small,
local, cache or forwards them to a real, recursive, DNS server. It
loads the contents of /etc/hosts so that local hostnames which do not
appear in the global DNS can be resolved and also answers DNS queries
for DHCP configured hosts.
The dnsmasq DHCP server supports static address assignments, multiple
networks, DHCP-relay and RFC3011 subnet specifiers. It automatically
sends a sensible default set of DHCP options, and can be configured to
send any desired set of DHCP options. It also supports BOOTP. |
