DNS Proxy Logging Question

scottj_01
All-

I am seeing some unusual logging with the DNS proxy. The astaro box is running version 8.102, on a core 2 duo with 4 gb of ram. In the past I would not see the DNS clients per query entries with any regularity. Now I see them in some cases several times per hour. Is there any preventitive corrective action I can take? Can the query be configured to a hard set value, or changed to run less often?

2011:11:08-08:46:15 OASIS named[5625]: clients-per-query decreased to 13
2011:11:08-09:04:59 OASIS named[5625]: clients-per-query increased to 18

    Jim, I don't think there's anything wrong with the Astaro.  I think the clients-per-query thing is just the number of DNS requests for resolution of an FQDN before the first request is satisfied; the DNS Proxy just reports on itself as it auto-adjusts the default number.

    The only problem I can think of might be slowly-responding DNS forwarder(s) configured in Astaro DNS - I like to use the OpenDNS servers.

    Cheers - Bob

    Bob,

    Thanks! The activity stood out as unusual. I am using DNS best practice, in addition to some of Sasha's tweaks. My DNS forwarders are Level 3 Comunications. 

    Regards,
    Jim
