[Dnsmasq-discuss] resolving on dnsmasq box itself?

[Bart Vandewoestyne]

Dear all,

I have a NAT-box setup with iptables masquerading to masquerade
out my personal internal home-LAN.  This box is called 'forsythe'
and has an internal IP of 192.168.0.1.  The external interface is
configued with DHCP by the DHCP-server from my ISP.

I am using this version of dhclient on my Debian GNU/Linux stable
box:

forsythe:~# dhclient -V       
Internet Systems Consortium DHCP Client V3.0.4

I have the following in my /etc/dhcp3/dhclient.conf file:

request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, host-name,
        netbios-name-servers, netbios-scope, interface-mtu;

After I have obtained an IP-address on my external interface, my
/etc/resolc.conf contains the following lines:

search telenet.be
nameserver 195.130.130.129
nameserver 195.130.129.161

I have the following options in my /etc/dnsmasq.conf file:

domain-needed
bogus-priv
interface=eth0

and in my /etc/hosts I have as only line:

127.0.0.1       localhost

Furthermore, I have

forsythe:~# cat /etc/hostname 
forsythe


So far so good... i can ping and do nslookup for for example www.google.com
but my question is about the following:

The hostname of my masquerading (NAT) box which also runs the dnsmasq
daemon is 'forsythe' and it has a statically assigned ip address of
192.168.0.1.  However, i cannot ping or do nslookup of the host 'forsythe':

forsythe:~# ping forsythe
ping: unknown host forsythe
forsythe:~# ping forsythe.
ping: unknown host forsythe.
forsythe:~# nslookup forsythe
Server:         195.130.130.129
Address:        195.130.130.129#53

Non-authoritative answer:
*** Can't find forsythe: No answer

forsythe:~# nslookup forsythe.
Server:         195.130.130.129
Address:        195.130.130.129#53

** server can't find forsythe: NXDOMAIN


Can somebody tell me what the *CLEAN* solution is to overcome this problem?

If i add the line

192.168.0.1     forsythe.localnet       forsythe

then

ping forsythe

works but the following commands fail:

nslookup forsythe
nslookup forsythe.
ping forsythe.


What is the clean solution to be able to ping and do nslookups
for the host 'forsythe'?

I also thought of adding a line

prepend domain-name-servers 127.0.0.1;

to my /etc/dhcp3/dhclient.conf so that my /etc/resolv.conf has an extra
line

nameserver 127.0.0.1

but I don't think this is the proper way to do it... it looks like I'm putting
dnsmasq in a loop this way...

Any suggestions for a *CLEAN* solution are welcome!
Bart
