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. -- -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" Heres the situation 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 http://www.google.com/search?hl=en&q=DNS+record+is+older+than+3+hours&btnG=Go 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? 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.
Check the DNS servers your windows DNS is using to forward requests to, your ISP may have changed one or more of their DNS servers. As an alternative you can setup your FreeBSD box as a DNS caching server, where it will forward requests to your ISP's DNS server(s) directly, taking your windows server out of the situation.
