Running Hobbit on FC5, installed Hobbit from the RPM packages on
SourceForge, which is a first as I typically have installed "manually".

It was not specifically added to /etc/hosts

I'll give this a shot and get back to you.

I also noticed some other odd behavior on this box after sending this
message.  The hobbit server itself was only reporting status on CONN BBD
INFO and TRENDS.  I made some modifications to the BBHOSTS file in
preperation of adding in other systems (created four PAGE groups in
BBHOSTS), but the changes never appeared.  I attempted to restarting Hobbit
from the script, but still no changes to main display, then restarted the
Hobbit Service that was listed in the Services applet.  Pages still did not
display, but the remaining info for the HOBBIT server (CPU, DISK, MEMORT,
etc) suddenly appeared.
