cve-2011-2464 affected the 9.4-ESV-R4-P1?
Hi all, on the ISC website i don't see that the 9.4-ESV-R4-P1 is affected by the CVE-2011-2464 is it because it's not really affected? or it's affected but i don't see it on versions affected because the 9.4-ESV-R4-P1 has it's EOL date to jun2011.

RE: bind-users Digest, Vol 902, Issue 1
Thanks for the answer, @ Andreas i made the test and i have the same performance as OS 64 bind 64. NB: when i reach the maximum throughput i still have enough free RAM, free CPU, free NIC capacity. So the limit is in Bind. What to do to reach more capacity? Tests: Test1: OS 64 bit, bind 64 bit == 5 qps Test2: OS 32 bit, bind 32 bit == 7 qps Test3: OS 64 bit, bind 32 bit == 5 qps Regards Issam Harrathi.

Re: better performance with 32 bit ! why?
When i start Bind on server2 i do it with -n 4 ( to use 4 thread) and on server1 i start bind with -n 8. And i see then on munin that the load is shared on all cores. For the load-server it's another server let's call it server 3. I know that tcpreplay is monothread so i lunch 2*25000 qps for example. And i use also resperf for testing, what i have with resperf and tcpreplay is nearly the same. What's important is that i 'm using always the same server3 to load the server1 and server2 (not at the same time, and using the same pcap-- rewrite twice to meet the mac@ of server1 and server2-- ) and i start with -n 4 on the 4 cores server and with -n 8 on the 8 cores. But i found best performance on the 32 bit server2 (4*2.33). Other information i begin the test only after sending for a few minutes 2 qps, so then i have only 5% of request that causes recursion, and about 15% nxdoamin answer, finally 80% of answer from cache. This is available for the 2 server since it's the same original pcap written twice. Do i have to use bind compiled and running on 32 bit server to have better performance rather than bind compiled and running on 64 bit server? and to be more clear this is the last core of the 64 bit server: processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E5310 @ 1.60GHz stepping: 11 cpu MHz : 1600.058 cache size : 4096 KB physical id : 1 siblings: 4 core id : 3 cpu cores : 4 apicid : 7 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl vmx tm2 cx16 xtpr lahf_lm bogomips: 3177.52 clflush size: 64 cache_alignment : 64 address sizes : 38 bits physical, 48 bits virtual power management: and this is the last core of the 32 bit server: processor : 3 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU5140 @ 2.33GHz stepping: 11 cpu MHz : 2333.389 cache size : 4096 KB physical id : 3 siblings: 2 core id : 7 cpu cores : 2 fdiv_bug: no hlt_bug : no f00f_bug: no coma_bug: no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm constant_tsc pni monitor ds_cpl est tm2 xtpr bogomips: 4666.97 Regards.

better performance with 32 bit ! why?
Hi all, I'm testing the same version of bind 9.4-ESV-R4-P1 on two server, one is a 32 bit (on which i have a redhat 32 bit) and the second a 64 bit server on which i have a redhat 64 bit. on the 32 bit i reach 7 qps but on the 64 bit i only reach 5 qps (using resperf) and also with tcpreplay. Is it normal that bind when compiled and installed on a 32 bit server have better performance than bind when compiled and installed on a 64 bit server. the only différence between the two server is 64 bit vs 32 bit ( same RAM, same Disk, same NIC,...) and CPU is better on the 64 bit (2 Intel E5310 quad-core 1.6Ghz) than the 32 bit(2 Intel Xeon duad-core 2.33Ghz).

I know it's EOL but at least i have to find it here http://ftp.isc.org/isc/bind9/ Thanks Issam HARRATHI IMPORTANT.Les informations contenues dans ce message electronique y compris les fichiers attaches sont strictement confidentielles et peuvent etre protegees par la loi.

RE: forward first: iterative or recursive query
Thanks for the answer but:
*
In the example i post yesterday: on my server1 the recursion is enabled
(recursion yes), but the server1 can't recurse because i stop it on firewall
and it can't contact the outside.
*
You say Don't use forwarding from a recursive server to a non-recursive
server but when my server1 is recursive (and the firewall allow it to contact
the outside), and server2 don't recurse because in it's conf recursion is set
to no, when i ask my server1 about ftp.example.comftp://ftp.example.com (dig
@0 ftp.example.comftp://ftp.example.com) , server1 forward the query to
server2 which answer by the CNAME www.abc.comhttp://www.abc.com and then
server1 recurse to find the IP of www.abc.comhttp://www.abc.com. and
everything works fine.
*
you say If server 2 is auth-only or otherwise can't resolve the address of
www.abc.comhttp://www.abc.com/, then forwarding a query to it is not going to
work. No as i say when server1 really recurse ( recursion yes, and the
firewall allow the server1 to contact outside) and server2 don't recurse
(recursion no) all is ok: server1 forward the query to server2 which answer by
the CNAME www.abc.comhttp://www.abc.com/ and then server1 recurse to find the
IP of www.abc.comhttp://www.abc.com/. and everything works fine.
*
You say then using a stub zone for example.comhttp://example.com/ will
work, why i will use a stub zone since a forward do the same thing expected.
And my question is always this:
forward only; as i read means a recursive query, in other term a query with the
RD bit is enabled. which means that when my server1 (which has recursion yes
but can't recurse because the firewall don't allow it to contact the outside,
which finally means server1 can't recuse) ask server2 about
ftp.example.comftp://ftp.example.com, server2 will normally make all the work
means he read on it's zone, then find the CNAME, then make a recursion to
resolve the CNAME and finally send the IP to server1.
why server2 don't recurse to find the IP of www.abc.com?
thanks for your help.

Objet : Re: forward first: iterative or recursive query
If recursion is disabled, forwarding doesn't happen. I think you've confused
some terms and configurations.
Don't use forwarding from a recursive server to a non-recursive server. Use a
stub zone instead, if you can't rely on the recursion process to find the
correct server to query.
If server 2 is auth-only or otherwise can't resolve the address of
www.abc.comhttp://www.abc.com, then forwarding a query to it is not going to
work. However, if server 1 is a caching server and is able to resolve
www.abc.comhttp://www.abc.com, then using a stub zone for
example.comhttp://example.com will work; server 2 will send the CNAME record
to server 1, and then server 1 will resolve the final address record on its own.

So forward first send an itérative or recursive query?
And how i can send a recursive query with the statement forward ( without using

Re: priority with A record?
Thanks Kevin for the answer, But rrset-order, can only disble the round robin (cyclic=round robin | random= random | fixed=disable round robin) And sorlist prioritise basing on IP of the client, i don't see anyway how to send( for example) 75% of http traffic to bigserver1.mysite.com and 25% of traffic to smallserver1.mysite.com And for the SRV which make exacly what i want, it's not supported by browser. May be with bind10 we will have this feature for A record like what we have now for MX! Thanks.

In this 2 case it will send 50% of traffic to ns2 and 50% to ns0; Is there anyway to enable priority on A or NS record? Thanks. For NS records, there is no way to do this in BIND, and it's completely unnecessary anyway, since every major DNS full-resolver implementation will keep track of how fast nameservers respond -- based on round-trip times, known as RTTs -- and prefer faster-responding nameservers over slower-responding ones. So the load spreads itself automatically, and failures -- which are assessed as really bad performance -- are routed around. For A/ records, there are mechanisms to control the order in which the records are presented. See sortlist and rrset-order (not sure that rrset-order even exists in later versions of BIND, since I've never used it in production). However, these are only practical on tightly-controlled intranets, where all of the BIND-instance configurations can be kept in sync with each other, otherwise one BIND instance may undo the careful address-record ordering that another performs. rrset-order and sortlist are pretty much useless for Internet names, since the vast majority Internet users get their DNS through intermediate resolvers, which will usually randomize or round-robin the responses whenever they are answering from their caches. As another poster pointed out, SRV records provide the capability for the domain owner to implement per-name failover and weighting of targets, in the DNS data itself. But, thusfar the DNS community hasn't had much success getting client-software developers (e.g. browser developers) to adopt SRV record support. Meanwhile, certain network-hardware companies (including among others a certain huge router vendor) rake in big money with their sledgehammer load-balancer device approach to the problem. There are software approaches to network load-balancing as well, but I have no direct experience with those. - Kevin -- next part -- An HTML attachment was scrubbed...

Or, get a DNS balancer that will send balance the IP addresses sorted in random, but weighed order. Note that there are many technical and logicalproblems with DNS balancers.
