Most BSD networks do not have dynamic DNS updating enabled on their nameservers, but that is the capability you seem to be asking about. If your network = does have this enabled, it's possible that using dhclient to release and = renew a DHCP lease on the BSD machine would be the right approach. Otherwise, change the zone file on the primary DNS server directly by = hand. --=20 -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to = "freebsd-questions-unsubscribe@freebsd.org" Heres the situation=20 I'm in windows environment mainly, I recently setup a BSD box (static = IP, and DNS pointing to the windows DNS server) With Exim, SA and CLAM_AV All has been running relatively well (3 months give or take) Till today I started getting this: milter# freshclam ClamAV update process started at Mon Dec 12 15:05:34 2005 WARNING: DNS record is older than 3 hours. WARNING: Invalid DNS reply. Falling back to HTTP mode. Google gave me=20 http://www.google.com/search?hl=3Den&q=3DDNS+record+is+older+than+3+hours= &btnG=3DGo ogle+Search One tell me that's its ok There is no reason to be concerned - most likely you have a caching DNS server at the gateway and this is causing it. DNS query is designed to minimise load on the datbase server when determining if the database = version is uptodate. But if this method fails it would just query the database = server The other , leaves me wondering I get this error when running freshclam: Invalid DNS reply. Falling back = to HTTP mode or ERROR: Can't query current.cvd.clamav.net . What does it = mean?=20 There is a problem with your DNS server. Please check the entries in /etc/resolv.conf and verify that you can resolve the TXT record = manually: $ host -t txt current.cvd.clamav.net If you can't, it means your network is broken. You'll be still able to download the updates, but you'll waste a lot of bandwidth checking for updates.
