trouble with name resolution
I am having a problem getting "Unable to resolve hostname" errors for the conn test for names that are in our DNS system. The bb-hosts entry looks like:
0.0.0.0 ppd2.wcm.ess.usda.gov # conn
the return from nslookup is:
-bash-2.05b$ nslookup ppd2.wcm.ess.usda.gov Server: 199.128.64.2 Address: 199.128.64.2#53
Non-authoritative answer: ppd2.wcm.ess.usda.gov canonical name = ppd.wcm.ess.usda.gov. Name: ppd.wcm.ess.usda.gov Address: 199.134.228.6
Any ideas how to correct this?

Larry, As default Hobbit does use ares resolver library. Maybe it's having some trouble who your nslookup doesn't showup.
You can play with two bbtest-net options, to help give a litle
more info on this issues...
-------<cut from man bbtest-net>---------------- --no-ares Disable the ARES resolver built into bbtest-net. This makes bbtest-net resolve hostnames using your system resolver function. You should only use this as a last resort if bbtest-net cannot resolve the hostnames you use in the normal way (via DNS or /etc/hosts). One reason for using this would be if you need to resolve hostnames via NIS/NIS+ (a.k.a. Yellow Pages). The system resolver function does not provide a mechanism for controlling timeouts of the hostname lookups, so if your DNS or NIS server is down, bbtest-net can take a very long time to run. The --dns-timeout option is effectively disabled when using this option.
--dnslog=FILENAME
Log failed hostname lookups to the file FILENAME. FILENAME should be a full pathname.
-------<cut from man bbtest-net>----------------
And you can play a litle with:
cd ~server/bin
"./bbcmd bbtest-net --debug ppd2.wcm.ess.usda.gov"
