Hi All
How does hobbit/bbtest-net use to get the dns query output? I am not using the --no-ares hook. I thought it uses dig @server host, but I am probably wrong about that.
Thanks

Also how do I go by compiling hobbit with djbdns library? I am already running djbdns's dnscache (internal) on hobbit server and like to take advantage if it for hobbit.

Write a patch. DJB's DNS library is not plug-compatible with the standard resolver library. Code will need to be rewritten. Of course, not much Bernstein's written is compatible with anything else, anyway... :-) -Alan

Amen. Much as I like some of DJB's tools, his coding style and disregard for any kind of API compatibility can be a real pain in the ....
I actually did look at his resolver library for Hobbit, but gave up trying to work out exactly how it should be used. Then I found the c-ares library and never looked back.
I do use his DNS daemons on my servers, but it's kind of "black-box" code - as long as it does what it should, I don't care *how* it does it.

It uses the c-ares library to perform the DNS queries, then formats the results into what you see.
It never uses "dig", "nslookup" or any other external program.

Using the djbdns resolver library requires some re-coding of the DNS routines in Hobbit. But why don't you just put "nameserver 127.0.0.1" into your resolv.conf file ? Then Hobbit will perform the lookups against your local dnscache daemon, and you'll get 90% of the benefits without having to change anything.

I was wondering if I there is a example query I can run to show technical groups. Ofcourse the web shows the output but may be from cli if I could run an example it would be cool.

That is what I have been doing exactly :-)
Thanks a lot

If you compile the c-ares library - the source tar.gz file is included in Hobbit - the output is very similar to that of the "adig" utility. (I think you'll have to run "make adig" to build that).
