me thus far, especially Henrik!)<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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 *<b><span style='font-weight:bold'>can</span></b>* see and talk to
the cluster “head node”.<o:p></o:p></span></font></p>

directly. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

the main Hobbit server would fail! <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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).<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>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… <o:p></o:p></span></font></p>
