-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I get dozens of these in /var/log/warn while fetching emails: <3.3> 2014-06-03 21:52:34 Telcontar named 24667 - - socket.c:5351: unexpected error: <3.3> 2014-06-03 21:52:34 Telcontar named 24667 - - connect(fe80::#53) 22/Invalid argument They started after an update, on 2014-03-31: <3.3> 2014-03-31 05:15:20 Telcontar named 2784 - - socket.c:5351: unexpected error: <3.3> 2014-03-31 05:15:20 Telcontar named 2784 - - connect(fe80::#53) 22/Invalid argument What do you think? Where should I look at? I found posts in google: https://groups.google.com/forum/#!topic/comp.protocols.dns.bind/fhWs_15pRB4 and the chap there reports getting the issue on Apr 1, that is, the day after me, and with the same bind version "BIND 9.9.4-rpz2.13269.14-P2 (Extended Support Version)" (mine is the official openSUSE 13.1 one). One of the answers says: “My guess would be that some miscreant out there created a glue AAAA record with an RDATA of "fe80::" and your network stack balks at connecting to such an abomination.” I don't really understand what it means. Another answer says: Just mark fe80::/10 as bogus. AAAA records do not have enough information in them to disambiguate link-local addresses and map them to per machine scope id's. server fe80::/10 { bogus yes; }; which I don't understand either, or its implications O:-) The OP answered: “Thank you Mark for all your help in the mail list. I will try this instead, so is this happening when an link local client is trying to query my server?” And the thread ends, so I assume it worked. [...] Ok, so I add that line to my named.conf, and they dissapeared (I run fetchmail to test). I watched "/var/log/named" and saw interesting things: <3.6> 2014-06-04 04:31:47 Telcontar named 10746 - - error (host unreachable) resolving 'opensuse.org.rhsbl.ahbl.org/A/IN': 10.230.230.230#53 <3.6> 2014-06-04 04:31:47 Telcontar named 10746 - - error (host unreachable) resolving 'opensuse.org.rhsbl.ahbl.org/A/IN': 192.168.230.230#53 <3.6> 2014-06-04 04:31:48 Telcontar named 10746 - - error (host unreachable) resolving 'opensuse.org.rhsbl.ahbl.org/A/IN': 10.230.230.230#53 <3.6> 2014-06-04 04:31:48 Telcontar named 10746 - - error (host unreachable) resolving 'opensuse.org.rhsbl.ahbl.org/A/IN': 192.168.230.230#53 Those would be local IPs, right? How are they related to opensuse.org? I think this comes from spamassassin checks, or amavis. - -- Cheers Carlos E. R.
