Hi everyone..
Ive got some jabbered notification callback to non existing host error in my log.

Jan 17 21:49:29 server jabberd_notification/c2s[156]: [8] [::ffff:192.168.12.205, port=62298] connect
Jan 17 21:49:29 server jabberd_notification/c2s[156]: SASL callback for non-existing host: serv.mydomain.com
Jan 17 21:49:29 server jabberd_notification/c2s[156]: [8] [::ffff:192.168.12.205, port=62298] disconnect jid=unbound, packets: 0

I would guess it has to do with the reverse dns. But the sudo changeip -checkhostname shows no errors. So I tried dig -x and got this:

; <<>> DiG 9.7.3-P3 <<>> -x 192.168.12.205
;; global options: +cmd
;; Got answer:

;; WHEN: Wed Jan 25 12:58:54 2012

Everything looks fine (to my knowlagde), but I'm wondering if the server: should not state my 192.168.12.205 ip?

many thanks.

This is your IP address :-

serv.mydomain.com. 10800 IN A 192.168.12.205

IN A means its an A record
IN CNAME means its an alias

The entry in RED is the server that DIG queried, if you don't specify a server it uses the loopback address or if set via DHCP the DNS server address.

;; SERVER: 127.0.0.1#53(127.0.0.1)

If you want to get dig to do your query from another server you'd have to use

dig -x @otherserver 192.168.12.205

Thanks for a fast reply. That explained it. I think the problem is in my reversed DNS. Ill check that with my ISP tomorrow. thanks again. These stuff is a bit tricky for non pros.

Is generally it a bad idea to have multiple PTR when running a lion osx server with the usual standard stuff turned on?

Ist now solved. Once the reversed DNS was set up and everything restarted he could connect and the message is gone. :)
