I remember somewhere in the manpages,

The hobbit server when doing fping conn test, it will try using FQDN and
if
not resolvable,
it will use the ip address(from bb-hosts) file.

Is this a correct statement ?

I will summarize the answer here

Pretty confident if the DNS lookup fails it times out and marks the conn red
=(  If you don't need it to do a DNS lookup simply add testip.

 Josh,

I think the first statement is true.  I have many items monitored by
hobbit which are not registered in DNS (I live with a bunch of windows
centric team mates and they rely on WINS not DNS.   None of these items end
up with conn=red, but they are ID'd in the output from bbtest on the hobbit
server.  Here is that output:

DNS statistics:
# hostnames resolved  :      383

# failed              :       77
# calls to dnsresolve :      414

Notice that I have 77 monitored items which fail the DNS lookup.

Neither.   It tries DNS, then it tries the
IP address in the bb-hosts file.   If it can ping the IP address it sets the
conn dot to green.   The only place I have found that reports it could not
resolve the name via DNS is in the output I copied into my email.

found the manpage.

http://www.hswn.dk/hobbit/help/manpages/man1/bbtest-net.1.html

but still not sure about ping test. will ping(conn) test will do the same
like testing of telnet,http type of services.

 --dns=[ip|only|standard] Determines how bbtest-net finds the IP adresses
of the hosts to test. By default (the "standard"), bbtest-net does a DNS
lookup of the hostname to determine the IP address, unless the host has the
"testip" tag, or the DNS lookup fails.
With "--dns=only" bbtest-net will ONLY do the DNS lookup; it it fails,
then all services on that host will be reported as being down.
With "--dns=ip" bbtest-net will never do a DNS lookup; it will use the IP
adresse specified in bb-hosts for the tests. Thus, this setting is
equivalent to having the "testip" tag on all hosts. Note that http tests
will ignore this setting and still perform a DNS lookup for the hostname
given in the URL; see the "bbtest-net tags for HTTP tests" section in *
