This is a follow up to the question, Ping to dnsmasq's host resolvesto 127.0.0.1, because that answer doesn't work for me. It should work -- I found another one having the same answer: https://bugzilla.redhat.com/show_bug.cgi?id=470391

In both above cases, the cause was having dnsmasq's hostname listed as 127.0.0.1 in the /etc/hosts file. But mines doesn't:

$ head -2 /etc/hosts
127.0.0.1       localhost.localdomain           localhost
192.168.2.100   jupiter.myhost.dyndns.org       jupiter

but dnsmasq's hostname is still resolved as 127.0.0.1:

$ nslookup jupiter 
Server:         192.168.2.100
Address:        192.168.2.100#53

Name:   jupiter
Address: 127.0.0.1

What's wrong?

Update:

I'm using dnsmasq as my DNS server, and I didn't put any configuration regarding dnsmasq's hostname in dnsmasq's configuration. So, regarding the A record, this is all that I know:

$ dig jupiter 

; <<>> DiG 9.9.3-rpz2+rl.13214.22-P2-Ubuntu-1:9.9.3.dfsg.P2-4ubuntu1 <<>> jupiter

  • What A record for jupiter set in the zone file of DNS server? – VL-80 Jan 16 '14 at 3:38
  • Thx. OP updated. – xpt Jan 16 '14 at 3:43
  • So, your DNS server is returning 127.0.0.1 on request to resolve jupiter. That is why nslookup shows 127.0.0.1. Now we need to set correct A record for name jupiter. – VL-80 Jan 16 '14 at 4:03
  • and to do that with dnsmasq...? – xpt Jan 16 '14 at 4:07
  • Well I am not familiar with dnsmasq, but I looked at Wikipedia article about it. It looks like it just forwards data to/from real DNS server. How is your network setup? Do you have any DNS server? Or dnsmsq is only thing of this sort you have? – VL-80 Jan 16 '14 at 4:11
