Public bug reported:
Binary package hint: pdns
I'm testing PowerDNS as a secondary DNS for my domain. I'm configuring
it with this in /etc/powerdns/named.conf:
zone "josefsson.org" {
type slave;
file "/var/cache/powerdns/josefsson.org.bak";
masters { 213.115.69.130; };
};
Starting PowerDNS results in this in syslog:
Jan 23 15:40:35 kil pdns[13915]: [bindbackend] error at Sun Jan 23 15:40:35
2011 parsing 'josefsson.org' from file '/var/cache/powerdns/josefsson.org.bak':
Unable to open file '/var/cache/powerdns/josefsson.org.bak': No such file or
directory
Jan 23 15:40:36 kil pdns[13915]: Initiating transfer of 'josefsson.org' from
remote '213.115.69.130'
Jan 23 15:40:36 kil pdns[13915]: AXFR started for 'josefsson.org', transaction
started
Jan 23 15:40:36 kil pdns[13915]: AXFR done for 'josefsson.org', zone committed
Querying for a domain in that zone results in SERVFAIL and the log gets
this:
root@kil:/etc/powerdns# Jan 23 15:40:50 kil pdns[13915]: Database module
reported condition which prevented lookup (Zone for 'josefsson.org' in
'/var/cache/powerdns/josefsson.org.bak' temporarily not available (file
missing, or master dead)) sending out servfail
Sometime later I get:
Jan 23 15:41:36 kil pdns[13915]: 1 slave domain needs checking
Jan 23 15:41:37 kil pdns[13915]: Domain josefsson.org is stale, master serial
2011012104, our serial 0
Jan 23 15:41:37 kil pdns[13915]: Initiating transfer of 'josefsson.org' from
remote '213.115.69.130'
Jan 23 15:41:37 kil pdns[13915]: AXFR started for 'josefsson.org', transaction
started
Jan 23 15:41:37 kil pdns[13915]: AXFR done for 'josefsson.org', zone committed
And it continues and downloads the zone every minute or so.
Restarting PowerDNS results in a somewhat better log message:
Jan 23 15:43:02 kil pdns[13944]: [bindbackend] error at Sun Jan 23
15:43:02 2011 parsing 'josefsson.org' from file
'/var/cache/powerdns/josefsson.org.bak': Parsing zone content on line 33
of file '/var/cache/powerdns/josefsson.org.bak': 'bar' doesn't look like
a qtype, stopping loop
Line 33 is this one:
foo bar 14400 TXT "Med space"
This indicates that whatever code did the zone transfer forgot to escape
the " " (SPC) as "\ " (backslash SPC). This is a bug, pdns needs to
handle domains with space in them.
The zone has this record:
root@kil:~# dig foo\ bar.josefsson.org txt
