Thnx for the tip. Found out that it was not the airport UDP port. It is
some misconfiguration in my DNS, but still don't get why it doesn't work
as expected. For some reason my DNS-name is snipped just before the TLD.
Oh btw i changed some configs
I prepended to /etc/syslog.conf the next and deleted what I wrote above
# Log remote Airport Express
And in rc.conf I changed the above to:
syslogd_flags="-b myhostname.intranet.mydomain.org -a
So what comes in on syslogd looks like "airport.intranet.mydomain" so no
.org or something. I really don't get where that comes from. But now
syslogd rejects because of "name mismatch".
I suppose something is wrong with either my DNS or my DHCP (appending
the domainname??), but at dhcpd I have the option "domain-name" set to
"intranet.mydomain.org". So still don't get whats going wrong.
My dns gives a the right IP and reverse gives right name.
dig airport.intranet.mydomain.org --> 10.0.10.30
dig -x 10.0.10.30 --> airport.intranet.mydomain.org
So anyone any ideas?
