BIND/NAMED and /etc/hosts

Hi,

I've set up a bind server, following the wiki and the forum

on an other PC, I have set /etc/resolv.conf tu use this local DNS server instead of the ones proposed by my provider. the redirection works very well.

On my local network I have multiple machines (let's say A B C and D) and so each one has a /etc/hosts file to see each other by name.

What I would like to do is that my DNS server "shares it's /etc/hosts" file with others machines. How can I do to be able on machine B to execute a "ping D" without having the corresponding line into the B's /etc/hosts file ?

Thanks for your help

That's what the BIND server does, you want to setup a zone for your own network. however, linux will take /etc/hosts over a DNS lookup, so when you verify your BIND zone works (using nslookup) you can get rid of the hosts in /etc/hosts.

I did switch to dnsmasq but it cannot handle more than 2 DNS servers so I'm trying to comme back to BIND/NAMED server.

It still don't work for me and I can't see why. Resolving a website works well (like www.gentoo.org) but resolving a local PC (ordi1 or ordi1.mynetwork) doesn't work

Copies of my files :
bind version : 9.2.4

/etc/resolv.conf

/etc/resolv.conf

Put it as the first one on that nameserver list. And make sure you don't have a daemon called nscd running, it caches the queries and in situations like this can provide some false results.

I did it already, but the result is the whenever it is the first or the third
And there is no nscd daemon on my server, neither my client

Ok. Are those bind zone files completely present here or did you copy-paste just the beginning of them? Because at the moment it seems your zone files are pretty empty without any actual information about your hosts.

they are complete, they are the same as in the forum exemple : https://forums.gentoo.org/viewtopic-t-402251.html

What I would like is to avoid the creation of a zone file "mynetwork.zone"

any other idea ?

Please re-read the thread you posted above. It contains also the actual zone files filled with information about hosts. If you think of it, at the moment you don't have any host related lines in your bind config, so it has no way of knowing what (for example) 10.10.10.3 should translate to. That's my hint. :-)

Finally I have made what I didn't want : a script synchronizing the /etc/hosts file and zone files for local domain.

If it can help someone, I have done it folowing this tuto (French) : http://valaurea.free.fr/documents/sig11_bind9_2.html
