The curl manual says:
 
   --connect-timeout 
  Maximum  time  in  seconds  that you allow the connection to the
  server to take.  This only limits  the  connection  phase,  once
  curl  has  connected this option is of no more use. See also the
  -m/--max-time option.
 
   -m/--max-time 
  Maximum  time  in  seconds that you allow the whole operation to
  take.  This is useful for preventing your batch jobs from  hang-
  ing  for  hours  due  to slow networks or links going down.  See
  also the --connect-timeout option.
 
Other HTTP clients will have similar options.
 
Tony.

It means that the statistics channel should be opened? Is there timeout 
mechanism? May curl query be not stucked?

Indeed. Actually, I forgot I have a blog article about this:

Is there other methods or APIs to monitor qps?

[liumingxing]

Hi， all
　I want to monitor query rate of BIND. It is problematic to use rndc status 
because the command has no timeout. 
Is there other methods or APIs to monitor qps?

Only at debug level 3, for example:
 
2015-09-01.11:25:55.851 client: debug 3: client 127.0.0.1#60986/key local-ddns: 
view auth: update
 
Other preliminary update checks are at debug level 8, e.g.:
 
2015-09-01.11:32:32.162 update: debug 8: client 127.0.0.1#60986/key local-ddns: 
view auth: updating zone 'dotat.at/IN': update section prescan OK

How does named log update request

[liumingxing]

hi,
In my server, I found update need longer time, So I want to check why by 
checking logs.
  As we know, named Logging of all dynamic update transactions. In the update 
channel file, how I can know when the server receives update request?

You could also use RPZ to provide answers for only the hosts in question. This 
would return a specified address for the individual entry while sending queries 
for other entries outside to the internet for resolution. RPZ requires an 
appropriate version if Bind 9 plus some options statements.

 Hi, all
 We hava a domain name example.com while now we have application servers 
 that are located in  in the localnet with private addresses and ones in the 
 external internet.  We want to setup a
 recursive in local networks that can provide recursive service and auth 
 service that internal users are  redirected to the internal servers and the 
 external users are guided to outside servers.
 
 Thanks

Re: xfer log file

[liumingxing]

在 2014-11-20 19:02, Graham Clinch 写道:

In the xfer log file, there are line of request to servers and ones of
reply from the servers.  Do they come in pairs? If do, are they next to
each other?

Assuming we're thinking of the same xfer log (categories
xfer-in/xfer-out)...

In normal operation you could expect pairs:

* '(A|I)XFR started'  '(A|I)XFR ended' for xfer-out,
* 'connected'  'Transfer completed' for xfer-in

yes.

but they won't necessarily be next to each other - a second transfer may
start before the first has finished (however, perhaps with
transfers-in/transfers-out set to 1...?)

Yes. it is not necessary for them to be next to each other.
But how to pair two lines which are a pair but not next to each other?
Are there identification to locate them?

Sometimes, to find pairs are needed to found to fix zone transfer problems.

It'll be different in error/failure situations.

Is there a particular reason to be interested in whether a transfer
completes before the next one starts?

Graham

Re: Re: glub or authauthority NS is cached and used at a cache dns server?

[liumingxing]

I have read your blog and do not agree with you about one of your conclusions 
to non-existence of ns rrs of www.qq.com in the ns-tel1.qq.com server. One 
recursor must request ns rr(s) of www.qq.com to the ns[1-4].qq.com server 
before requesting to ns-tel[1-2].qq.com. When it receives the ns rrs and glue 
rrs of www.qq.com from ns[1-4].qq.com, it may at last ask  ns-tel[1-2].qq.com 
what your ns rr(s) is(are). If non-existence, the recursor will continue to ask 
other disired type of rrs of www.qq.com to the   ns-tel[1-2].qq.com, otherwise 
will send requests to the informed servers. No other bad things are seen.

 The TTL are different. which type is used in Cache DNS?
