[Dnsmasq-discuss] DHCP for multiple subnets - hostname to IP mapping

[Brandl, Tobias]

Hi,

I'm struggling for a couple of days now with the DHCP setup in my sample
network environment. Here's what I'm trying to do:
* I'm setting up an environment where severs should get their IPs via
DHCP name -> IP mapping (fixed or static IP)
* Each server has two NICs, one used in a client LAN (192.168.1.0/24)
and one in a backend LAN (storage access, etc. - 192.168.101.0/24)
* Each server should get IPs for the different subnets based on the
hostname provided, e.g. 
** requesting an IP for server01(.clnt.localnet) via the client LAN
should be mapped to 192.168.1.10
** requesting an IP for server01(.bknd.localnet) via the backend LAN
should be mapped to 192.168.101.10

I think I've tried almost every combination of dhcp-host, dhcp-range,
dhcp-fqdn, and /etc/hosts entries without any success.
I'm either getting "no address available" once the second interface
comes up or it receives an IP different from the one set in /etc/hosts -
even though dnsmasq logs show that the name is "known" (matching
dhcp-host entry found).

Could anyone please help to sort this out?

If needed I will post my dnsmasq.conf and /etc/hosts entries, but maybe
this can be answered generically.

Thanks a lot,

Tobi
