On the machine running gmetad are there
any iptables rules that may be blocking inbound UDP traffic on
port 8649.

Ganglia unable
to report remote client
My ganglia setup is able to
report only
one guest which is local server on which gmond and gmetad both
are installed
. It does not show up other clients inspite of proper
configurations with
gmond .
Remote gmond process is running
absolutely
fine .
Debugging done so far
1) I also verified that port 8649
are
free and not used using lsof -i tcp:8649
2) /var/log/messages do not show
any
error
3) all the processes - gmetad ,
gmond
are running fine
Please suggest steps/tips to
debug the
issue further .
