Hi everybody,
I started to install Ganglia core package on RH Linux 6.1
---------
Linux pcfarm.pnpi.spb.ru 2.2.18smp #3 SMP Tue Feb 12 19:15:04 MSD 2002
i686 unknown
--------
Everything with installation process was fine (tar, ./configure, make,
make install, ...).
I started three gmond on different machines in our cluster with
negligable changes in /etc/gmond.conf (in attachment).

With 'ntop' on pcfarm I see that multicast packets are going mainly from
pcfarm (about 150 packets and only two packets from pcfarm-02).
In principle how I said the same picture on any other host.
Any ideas are welcome.
Thanks.
