Make sure that there aren't copies of the same node somewhere else in the bb-hosts file, perhaps with 0.0.0.0 as the IP address. A "red" test means that the Xymon server is really trying to ping something, and the ping is failing. Blank means that the host is not being pinged, so you are probably looking at a copy (0.0.0.0 host # noconn) entry.
Just guesses. Let us know when you figure it out.
the /etc/hobbit was recreated by the script /usr/share/hobbit/init-common.sh.
The bb-hosts contains indeed my old tests, so I removed the script above from the starting script, and everything is fine now.
My mistake was to use sometimes /etc/init.d/hobbit start and sometimes $HOBBITHOME/hobbit.sh start. The first recreated the /etc/hobbit, but the second didn't create anything.
thanks for the answers.
I'll be more carefull with startup scripts next time.
