Thanks for you fast reply. bert hubert wrote: > Is what PowerDNS Recursor would log under similar circumstances. This > requires you to change the log-common-errors setting from the default. I briefly enabled 'log-common-errors' but after realizing that it logs qnames I had to disable it again since I have to avoid logging qnames. I assume there is no way to log ENOBUFS events without logging qnames then via a config change only. thanks, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu signature.asc Description: OpenPGP digital signature ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users

As it stands, qname minimization requires workarounds to make it viable. (Re-)standardization is also still going ont. But it will happen eventually.

[Pdns-users] pdns-recursor: expected log entries on sendto ENOBUFS error + qname minimization
Hi, I've been pondering with "sendto failed: No buffer space available" errors using unbound [0]. To see how pdns-recursor behaves on the same box I switched from unbound to pdns-recursor and don't get any similar log warnings. Now my questions are: What log entries (if any) would pdns-recursor produce on ENOBUFS sendto [1] errors when run in loglevel 6? [2] If no log entries are expected on that loglevel, starting at which loglevel would pdns-recursor start logging such events? Is there a description of what a given loglevel entails? (I must not log any queries) and an unrelated question: I've found an old GH issue about adding QNAME minimization support to recursor. Is my understanding correct that this feature is not a priority and will unlikely be added anytime soon (next 6 months)? thanks! nusenu [0] https://nlnetlabs.nl/pipermail/unbound-users/2019-January/011257.html [1] https://www.freebsd.org/cgi/man.cgi?query=sendto&apropos=0&sektion=0&manpath=FreeBSD+12.0-RELEASE+and+Ports&arch=default&format=html [2] https://doc.powerdns.com/recursor/settings.html#loglevel [3] https://metrics.torproject.org/networksize.html signature.asc Description: OpenPGP digital signature ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users
