My feeling from reading postings on this list for a number of years
is that most people who are currently using BIND will stick with BIND.
In general, there is a mistrust of MS code.  There were
interoperability problems with BIND and MS W2k DNS a few years ago, but
I have experienced no major problems since August 2002, when MS
resolved my last major problem.  I use MS W2k+3 DNS mainly for the
AD-related zones, where I want the AD-integrated security of the DDNS.
I do have one forward zone and its five reverse zones on the MS DNS
Server, all under the control of a MS DHCP Server.

Bind 9.2.4 slaving problem [bind 9.2.1 and bind 8.3.3]
Greetings. I have a master name server running BIND 9.2.1 [Debian Woody - server not available on the Internet] and a slave server running bind 9.2.4 [Debian Sarge - not currently available on the Internet] and two others running bind 8.3.3 [Debian Woody - on the Internet]. The 9.2.1 is a master for all the others to slave from. I have an entry in a zone defined on the master as the following: > $ORIGIN example.com. > spamhaus-datafeed IN NS local-rbl-a > spamhaus-datafeed IN NS local-rbl-b When I issue the following command: #> host -t nx spamhaus-datafeed.example.com 127.0.0.1 on the master server OR the BIND 8.3.3 servers I get an answer pointing me in the right direction. On the Sarge 9.2.4 however I get a: "Host spamhaus-datafeed.example.com not found: 2(SERVFAIL)" error. I can see the records in the local db file on all machines. The 8.3.3 machines are a little more verbose in that they list the TTL for each record, the 'IN' record qualifier and a fully qualified hostname at the end of the record [ex. local-rbl-a.example.com.]. The 9.2.4 machine simply lists a record without the TTL, without the 'IN' qualifier, and without the $ORIGIN on the hostname at the end of the record [ex. local-rbl-a]. I have looked through the DNS and BIND book from O'Reilly but it has not led me to anything helpful. The closest I've come to finding something referring to this issue is...

Look, stop wasting your time on this pointless make-work exercise. BIND4 is DEAD. Nobody should be running it. Consult the list archives about this, probably from around 2000. There have been plenty of statements about the expiration of BIND4. Tell your users and management that BIND4 is well beyond end-of-life and has to be replaced with BIND9. If they insist on continuing to run dead code, get them to put that in writing and agree that they, not you, will be held responsible for all the consequences of that action: security holes, no support, no understanding of new DNS protocol features, increased maintenance & administraton costs, etc, etc. In terms of raw throughput BIND9 will always be slower than BIND4, all other things being equal. That's because BIND9 uses more complex data structures and is paranoid about error checking. However that performance penalty is not noticeable in normal operations. I doubt if anyone at your organisation would be able to tell the difference between the re...

BIND4 is dead. That's enough justification by itself. Some of the root servers -- who get orders of magnitude more queries than your server -- run BIND9. None run BIND4. There are very good reasons for that. Query throughput isn't everything, even for the guys running the busiest name servers on the net.

In addition to the other replies, let me add this -- 1) Look at the archives of bind-users (and also the bind9-users) mailing lists, bind9-users was merged into bind-users a number of months ago, but the bind9-users archive still exists on the isc.org web site. These archives contain MANY W2k/AD-related postings over the past years. 2) There are a number of options, including a) Use DDNS only for the W2k "_" zones, and have the workstation registrations static in BIND. The DDNS can be on a W2k DNS Server or BIND. b) Put the W2k workstations in a sub-domain and have the workstations self-register or register via DHCP. Again the DDNS can be either W2k or BIND. c) If you use W2k DNS, then you can slave the zones on your BIND server(s).

Performance of Bind 9.2.3 vs BIND 4.8.3
Hello All, I want to upgrade from BIND 4.8.3 to BIND 9.2.3. For this reason, I am doing a performance testing on the BIND 9.2.3 nameserver and the BIND 4.8.3 nameserver. I am doing this by measuring the time taken between sending the query from an application and recieving the response. The test application is something like this: start_time = curent_sys_time(); gethostbyname("myhost"); stop_time = curent_sys_time(); query_time = stop_time-start_time; I am using the above piece of code to send queries to: 1) A BIND 9.2.3 nameserver and, 2) A BIND 4.8.3 nameserver Both the nameservers run (not simultaneously) on the same system and are not in any network. I took about 50 readings for both nameservers. The readings of this test reflect that the response time (the value of query_time) in case of the 9.2.3 server is almost 50% more than the 4.8.3 server. i.e, a 50% performance degradation. This is holding me from upgrading the DNS. I know that it may be argued that BIND 9 provides security features -- etc. But, what is the point when the most basic query processing is not very efficient? As far as my understanding goes, BIND 9 servers are supposed to perform better than BIND 4 servers, isn't it? Any suggestions, clarifications are most welcome. thnx in advance, Nishant ...
