[Pdns-users] recursor 3.1.4 public interface problems

[Martijn Grendelman]

Hi,






In syslog:



and no other suspicous messages.

Output from 'lsof' proves this:

# lsof -Pn | grep recu|grep IPv4
pdns_recu  9501  root  4u  IPv4  2968055  UDP 127.0.0.1:53
pdns_recu  9501  root  5u  IPv4  2968056  UDP 213.207.104.11:53
pdns_recu  9501  root  6u  IPv4  2968057  TCP 127.0.0.1:53 (LISTEN)
pdns_recu  9501  root  7u  IPv4  2968058  TCP 213.207.104.11:53 (LISTEN)



However, on 213.207.104.11, things don't quite work as expected:

[EMAIL PROTECTED]:~> host www.sipo.nl 213.207.104.11
;; connection timed out; no servers could be reached

[EMAIL PROTECTED]:~> host -a -l sipo.nl 213.207.104.11
Trying "sipo.nl"
;; communications error to 213.207.104.11#53: end of file





Best regards,

Martijn Grendelman

I couldn't find anything about this in the issue tracker, nor in recent mailinglist archives, so I'll post here. I have an issue with the recursor, and I'm wondering if this is a bug. I have the recursor (3.1.4 on Debian, using the package from powerdns.com) listen on two interfaces: 127.0.0.1 and 213.207.104.11. All the evidence tells me that my setup is working. Jan 12 12:05:57 vodka pdns_recursor[9500]: Listening for UDP queries on 127.0.0.1:53 Jan 12 12:05:57 vodka pdns_recursor[9500]: Listening for UDP queries on 213.207.104.11:53 Jan 12 12:05:57 vodka pdns_recursor[9500]: Listening for TCP queries on 127.0.0.1:53 Jan 12 12:05:57 vodka pdns_recursor[9500]: Listening for TCP queries on 213.207.104.11:53 Now, on localhost eveything seems to work fine, for both UDP and TCP, as in: both host lookups and zone tranfers yield expected results when querying localhost. A telnet connection to 213.207.104.11:53 is 'closed by foreign host' immediately. To test for an issue with multiple interfaces, I removed 127.0.0.1 from the config, and made the recursor bind to 213.207.104.11 only. This made no difference. I am 100% certain that this is not a firewall issue. Did I hit a bug?
