 Posted: Mon Jul 25, 2005 12:18 pm Post subject: [Solved] DNS Randomly Dies |
 |
|
This is an odd one. I've been hosting my own DNS for my domain, and suddenly it's all .. "crapped out" is the technical term, I believe. The domain can no longer be found.
DNSStuff.com lists the correct IPs for the nameservers (the report for the doma can be read here), but - as you can see from that report - there are some very odd values coming from the servers. Mainly the fact that all the settings (TTL, Serial etc) are being reported as zero.
Here's /etc/bind/named.conf:
| Code: | options {
directory "/var/bind";
// uncomment the following lines to turn on DNS forwarding,
// and change the forwarding ip address(es) :
//forward first;
//forwarders {
// 123.123.123.123;
// 123.123.123.123;
//};
listen-on-v6 { none; };
listen-on port 53 {
any;
};
// to allow only specific hosts to use the DNS server:
//allow-query {
// 127.0.0.1;
//};
// if you have problems and are behind a firewall:
//query-source address * port 53;
pid-file "/var/run/named/named.pid";
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "pri/localhost.zone";
allow-update { none; };
notify no;
};
zone "127.in-addr.arpa" IN {
type master;
file "pri/127.zone";
allow-update { none; };
notify no;
};
zone "168.192.in-addr.arpa" IN {
type master;
file "pri/168.192.zone";
allow-update { none; };
notify no;
};
zone "ecliptical.co.uk" {
type master;
notify no;
file "/var/bind/pri/ecliptical.zone";
allow-transfer { any; };
}; |
... Aaaand here's /var/bind/pri/ecliptical.zone:
| Code: | ; Zone File for ecliptical.co.uk
$ORIGIN ecliptical.co.uk.
$TTL 60
@ 14000 IN SOA ns1.ecliptical.co.uk. tech.ecliptical.co.uk.
(
2005052702 ; serial
10800 ; refresh after 3hrs
3600 ; retry after 1 hr
1209600 ; expire after 3 days
86400 ) ; minimum TTL of 1 day
IN NS ns1.ecliptical.co.uk.
IN NS ns1.twisted4life.com.
IN MX 100 80.6.134.35
ns1 IN A 80.6.134.35
calypso IN CNAME ns1
www IN CNAME ns1
mail IN CNAME ns1 |
NOTHING to do with bind has been touched since it was last working fine. The server hasn't gone down, no IPs have changed, port 53 is still finding it's way to the correct box.
Anyone got any ideas?
Yes, bind is running -
| Code: |
tcp 0 0 localhost:domain *:* LISTEN 31700/named
tcp 0 0 192.168.1.5:domain *:* LISTEN 31700/named

A quick look in the log shows
| Code: | Jul 25 12:55:38 calypso named[32499]: dns_rdata_fromtext: pri/ecliptical.zone:3: near eol: unexpected end of input
Jul 25 12:55:38 calypso named[32499]: zone ecliptical.co.uk/IN: loading master file pri/ecliptical.zone: unexpected end of input |
I've looked through the file over and over and I can't see any problem with it (let alone the fact that it hasn't been touched since it was working fine a few days ago). |

This looks to be line 3 of ecliptical.zone. The number 14000, whatever that is supposed to be doesn't show up in a quick look through my BIND book. All the examples (and my own primary) are in the form "@ IN SOA", etc. Can't imagine why that would work and then not work.

It turns out the opening bracket for the SOA section has to be on the same line as the @ IN SOA bit. No idea why this only began causing problems now but that sorted it.
Thanks for your help  |
