Weird hobbit/proxy/CONN catch-22?

[Brodie, Kent]

OK guys, here's what I have (thank to all that helped me thus far,
especially Henrik!)

 

My setup involves a hidden cluster--  which means that from my MAIN
Hobbit server (BBDISPLAY), I cannot see nor ping the cluster nodes, but
I *can* see and talk to the cluster "head node".

 

Based on prior suggestions, I set it all up as follows:

 

Main BB server has config entries for everything, including the cluster
head node AND the cluster nodes it "can't see" directly.    

These entries are listed as:  

Hidden.ip.address.here   host.name.here             # noconn

 

"noconn" obviously, since the network tests from the main Hobbit server
would fail! 

 

---  

 

Next, I set up the cluster head node as a BB server.    Actually, its
main purpose is to run the network and such tests, and act as a proxy
server for the whole cluster.

 

---  

 

It all works.   Sort of!      On my main BB display, I see the entries
for the "unreachable" cluster nodes, which is very cool.    I see the
cpu, disk, files, msgs, etc.   But--   there's no connectivity (conn)
information or status information.  

 

---  

 

Catch-22?   How do I get the "conn" test to show up?   If I list "conn"
in the bb-hosts on my main Hobbit server, I am going to assume that the
conn tests will have issues, since that server(s) really are unreachable
from the BBDISPLAY host.      But if I set it up listed as "noconn" on
the BBDISPLAY server--  um, there's no conn data/column (a Homr Simpson
"D'oh!" goes here).

 

Any ideas?      The BBPROXY setup described above is working as far as
information exchange, as I am indeed seeing cpu, disk, files, info,
msgs, ports, procs, and that's all very very cool and good.   But I need
'conn' most of all.

 

Help!  (and thanks)

 

 

 

By the way - a suggestion for stuff down the road a bit:   When I set up
my proxy server (./configure -server), there was of course all of the
requirements I had to have met, such as having RRDTOOL, libpng, etc etc
all there.    That's great, except I have no intention of having this
other server doing anything other than running a few tests, and
forwarding it all on to the BBD server.   No data, no RRD, no graphs, no
apache, no html.      One big suggestion I have (since the proxy is such
a cool thing) is to perhaps including things like:  ./configure
-proxy-only   ?    Just a thought.   This may or may not be
complicated...
