Hello Thomas
Issuing the following command fixed the problem:
route add -host 239.2.11.71 dev eth1
Thanks a lot for your help!

Dear David,
Sometimes setting the route, esp on a node with two ethernet cards fixes
the issue.
To fix the ganglia problem I had to enter the command
route add -host 239.2.11.71 dev eth0
Then node14 showed up on the ganglia report.
Note, change your dev to be either eth1 or eth0 depending won where you
want the mulitcast signal to be sent...

[Ganglia-general] gmond does not collect data (from one node in a
farm)
Hello
Weizmann Institute farm runs plain gmond happily on multiple machines,
except for one.:
On that machine gmond service does run, it does respond to 'telnet
localhost 8649',
but the response only consists of the list of metrics and no collected
data.
The task of the 'failing' machine is a cluster gateway,
- It has two rather than one (active) network cards.
- The security policy for this machine is tighter than that of other
machines.
(Note however that the 'failing' machine does respond locally to 'telnet
localhost 8649')
- It runs kernel 2.6.9-11.ELsmp while the other machines run a 2.4 kernel
Except for these differences, the hw and SW of this machine looks similar
to that other machine/s in the farm.
Following are more details concerning this machine and running gmond on
it.
Please guide us how to detect the reason for one machine failing to
collect data via gmond.
In particular, please indicate if the tight security policy may cause the
problem (even though telnet does respond).
Thanks in advance

The machine is: Pentium III (Coppermine) dual CPU 512 MB memory
The kernel is: 2.6.9-11.ELsmp
The linux version is: Red Hat Enterprise Linux AS release 4 (Nahant Update
1)
All machines run gmond 3.0.1.
Replacing 3.0.1 by 3.0.2 on the 'failing' machine did not make a
difference.
All machines have the same (default) /etc/gmond.cong
The output of gstat on the 'failing' machine:
