Hi everyone I've got a very strange problem, first time since I'm using FreeBSD (from 3 I think). After a fresh install (freebsd 11.1-P8) I got a very strange behavior, if I dot ssh/ping fqdn I got a (after long time) ssh: Could not resolve hostname fqdn: hostname nor servname provided, or not known but if I do host fqdn I got the correct answer(instantly), and after that the ... sometime ... ssh/ping work fine, sometime ssh still not working. So I track with tcdump+wireshark, it seem the host try to resolv a AAAA record, but my server fqdn don't have a AAAA record (only V4 server), the host try 3 times after (3 time with AAAA). Instead a hosts fqdn do the correct dns request. I can use ssh -4 (and it's working), but it's seem every command who need a name resolution try the same thing and failed after some time, so lots of command become very slow. Inside my rc.conf no v6 configuration. Regards -- Albert SHIH DIO bātiment 15 Observatoire de Paris xmpp: jas@obspm.fr Heure local/Local time: Wed Mar 21 14:36:27 CET 2018
