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>

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>
