** SOLVED ** - thanks everyone, it's working now. I had additionally mistyped the IPs of the dev boxes >_<

UPDATE 2- Ok, parse errors are gone and no more errors in syslog. I'm still unable to ping using dev1 but I can using the ip address. Any ideas? I updated /etc/bind/local-network (see below). My resolv.conf contains- nameserver 10.0.1.2

I do 'ping dev1' this and get- ping: unknown host dev1 and this will show up in syslog-

Any ideas as how to diagnose further?

UPDATE 1- I see this error in my syslog: (i don't see where it would think the syntax is invalid)

Jun  1 16:19:08 local-dns named[2402]: dns_rdata_fromtext: /etc/bind/local-network:7: near eol: unexpected end of input
Jun  1 16:19:08 local-dns named[2402]: zone local-network/IN: loading from master file /etc/bind/local-network failed: unexpected end of input

I've been using /etc/hosts for a while now and it's getting a pain to manage. I'm interested in using BIND on a linux server for my LAN at home. I'd like to make it so any comp on my network can access the server 'dev1' and 'dev2' without having to set it up in a hosts file.

here are the ip mappings to my dev boxes- dev1 -> 10.0.1.50 dev2 -> 10.0.1.51

i set the dns server to use 10.0.1.2

I've look at some resources online but i haven't been able to get it working quite yet. here's what I have so far-

This is what's in my /etc/bind/named.conf.local:

zone "local-network" {
        type master;
        notify no;
        file "local-network";
};

and in /etc/bind/local-network:

$TTL 3D
@       IN      SOA     ns.local-network. ns.local-network. (
                        199802151       ; serial, todays date + todays serial #
                        28800              ; refresh, seconds
                        172800              ; retry, seconds
                        2419200              ; expire, seconds
                        86400           ; minimum, seconds
                        )
;
                NS      ns.local-network.  ; Inet Address of name server
;
localhost       IN      A       127.0.0.1
ns              IN      A       10.0.0.2
dev1            IN      A       10.0.0.50
dev2            IN      A       10.0.0.51

Does that look right?

and then I once the dns server is setup I need to tell my router that does dhcp to use the internal dns server I just setup instead of my IPSs, so all the comps on the LAN use it--right?

  • Dude, did you read my answer? Yes, your local-network file has a syntax error, and I told you what it is. – chaos Jun 01 '09 at 22:29
  • yes, thankyou! I had seen it but it took me a while to understand exactly you were meaning. – user7321 Jun 01 '09 at 22:55

    You're welcome. :) Now you need to add 'search local-network' to your resolv.conf. – chaos Jun 02 '09 at 02:32

Use dnsmasq. It's a lightweight DHCP/DNS server. It automatically serves stuff in /etc/hosts and DHCP leases as DNS entries, forwards everything else to your ISP's DNS server.

Works like a charm, extremely easy to configure.

Yeah, mostly. Your SOA record is missing its responsible-person email address, though.

  • Thanks again btw- I was initially confused by what you were saying. But this was indeed the cause of the parse error. – user7321 Jun 01 '09 at 23:06

I would fully qualify the file command in your named.conf.local so it would look like file /etc/bind/local-network

Also i would make sure that the bind daemon user has read permissions to the zone file.

Do you have any error messages in /var/log/messages or /var/log/daemon.log ? (I've seen bind write to both places.) 

$ORIGIN .  
$TTL 3600       ; 1 hour  
domain.com               IN SOA ns1.domain.com. user.domain.com. (  
                                2008123002     ; serial  
                                900        ; refresh (15 minutes)  
                                600        ; retry (10 minutes)  
                                86400      ; expire (1 day)  
                                3600       ; minimum (1 hour)  
                                )  
                        NS      ns1.domain.com.    
                        A       <ip of host>  

$ORIGIN domain.com.  
ns2             IN      A       x.x.x.x  
ftp             IN      A       x.x.x.x

  • good call, I checked /var/log/daemon.log and it looks like /etc/bind/local-network has some invalid syntax or something. I added an update to the original question – user7321 Jun 01 '09 at 22:25
  • Couple of other things, i would fully qualify your NS entry so it would look like ns.domain.local. (yes you need the period on the end) also you don't have your records setup right so your ns record should be NS IN A 10.0.0.2 (you are missing the 'IN' and as chaos said you are missing your responsible person – Zypher Jun 01 '09 at 22:31
  • ps added an example based off my working config ips/hostnames removed – Zypher Jun 01 '09 at 22:35
