Congrats. :) If you are relying on your nameserver for something critical (like outside resolution) you should seriously consider upgrading to BIND 4.9.6 since it has much better protection against hostname spoofing, etc. The easiest way for you to do that would probably be to upgrade to FreeBSD 2.2.5, which comes with BIND 4.9.6 in the base system. However neither is something you would need to do tomorrow... just something to plan on. [snip] >However, when I look in the /var/log/messages file, I am receiving >syntax errors all over the place. These errors point to my db files, >both db.domain and db.ip-number files. Ok, first off, if you are reporting error messages, please tell us what they are. :) I can guess at the one from your forward resolution file, but your PTR file didn't come through. Next time please send the files in the body of your letter, instead of as an attachment. They are small enough. >Now, qmail will not resolve remote names, but it will when I switch to >my secondary nameserver, which is run by my isp. >So. With all that said, I am lead to believe that there is indeed >something incorrect with my syntax. The syslog doesn't lie. :) If BIND sees an error, it will report it, and since it's the authority, you can assume that it's right. [snip] >BTW. I am using long names here, not short-cuts. This shouldn't matter, it's just a little extra work for you. >The name of the file is: db.dcoisp and the domain is dcoisp.net. SHould >I name the file, db.dcoisp.net? You could name it GeorgehasGreenHair and it wouldn't matter. :) Ok, here is a blow-by-blow for your zone file: dcoisp.net. IN SOA mail.dcoisp.net. 1 10800 3600 604800 86400 dcoisp.net. IN NS mail.dcoisp.net. ; here comes the hosts! localhost.dcoisp.net. IN A 127.0.0.1 bbs.dcoisp.net. IN A 208.128.192.226 mail.dcoisp.net. IN A 208.128.192.227 www.dcoisp.net. IN A 208.128.192.228 twcmedia.dcoisp.net. IN A 208.128.192.241 ; aliases anyone? dcoisp.net. IN CNAME bbs.dcoisp.net. It's a good idea to start with an origin statement, just so that your named doesn't get confused. Also, it doesn't cost you a thing to add a hostname for ns.dcoisp.net, and it looks a little more professional. You also need a zone contact in your SOA record. And you need parentheses to indicate that the SOA record is continuing on another line. Using the date, plus a counter at the end for your serial number will give you an integral accounting mechanism to keep track of changes. Finally, you can't have a cname for something that already has any other kind of record, which is at least one thing that you're getting syntax errors about. Here is how I'd set up the same zone: $ORIGIN dcoisp.net. @ IN SOA ns.dcoisp.net. ringlord.bbs.dcoisp.net. ( 1997110701 ; Serial 10800 ; Refresh 3600 ; Retry 604800 ; Expire 86400 ) ; Default TTL IN NS ns.dcoisp.net. IN A 208.128.192.226 ; This is in place of the cname ; here comes the hosts! localhost IN A 127.0.0.1 ns IN A 208.128.192.227 mail IN A 208.128.192.227 bbs IN A 208.128.192.226 www IN A 208.128.192.228 twcmedia IN A 208.128.192.241 Hope this helps, Doug Hostmaster, DALnet Internet Relay Chat network *** Proud operator, designer and maintainer of the world's largest *** Internet Relay Chat server. 4,168 clients and still growing. :-) *** Try spider.dal.net on ports 6662-4 (Powered by FreeBSD) *** Part of the DALnet IRC network ***
