 It is possible to put a non-standard port in dnsmasq
 configuration files using
 
 server=server1#port1
 
 So simply make your file look like
 
 server=server1#port1 server=server2#port2 
 server=server3#port3 server=server4#port4
 
 call it /path/to/servers.dnsmasq
 
 and tell dnsmasq to read it as a dnsmasq configuration file.

Yes. That's exactly what it does.

Yes, that's a good way to do it.

The first answer returned will be the one used. I don't understand the
second part of your question, sorry. Could you explain another way what
you want to do?

Sorry for my poor english.

Let me describe it as follows:

Just as you have told me: the first answer returned will be the one used.

But, after the  the first answer returned, there still will be other
query restults returned subsequently due to the parallelly query done
by `all-servers' option.  So, how the dnsmasq deal with the remain
ones?  Does it simply discard the remainly returned results?

 I want to use the `--resolv-file=' option to invoking the file

 Say, I named this file as resolv-file.dnsmasq, and its content has the

 Then I use the following command to run the dnsmasq:

 But, at this step, I get the following errors:

 dnsmasq: no servers found in /path/to/resolv-file.dnsmasq, will retry

 So, how to let dnsmasq using multiple upstream dns servers with
 non-standard ports?

Re: [Dnsmasq-discuss] How to let dnsmasq using multiple upstream dns servers with non-standard ports.

[Simon Kelley]

You can't put non-standard ports in a resolv-file, the format of those
files does not include ports.

It is possible to put a non-standard port in dnsmasq configuration files
using

server=server1#port1

So simply make your file look like

server=server1#port1
server=server2#port2
server=server3#port3
server=server4#port4

call it /path/to/servers.dnsmasq

and tell dnsmasq to read it as a dnsmasq configuration file.


sudo dnsmasq -d -p 5353 -C /path/to/servers.dnsmasq  --all-servers



That should do the trick.

Simon.

According to the help of dnsmasq, it seems that the more appriate
method should be using the following option to invoke the above
configuration file:

--servers-file=   Specify path to file with
server= options

sudo dnsmasq -d -p 5353 --servers-file=/path/to/servers.dnsmasq  --all-servers

In addition, I want to know another thing: how to control the shortest
time with which I wait for the responding from these upstream dns
servers.  I mean: when using `--all-servers' option, the dnsmasq will
query all of these dns servers parallely and I want to use the most
firstly query returned to me and then throttle the remail query for
the spefific domain name.  Is this possiable?
