A more common occurence is that people have firewall turned on. You need
to make sure you allow inbound udp port 8649 on host A and outbound udp
port 8649 traffic on host B. Also if you are not using multicast I would
remove the
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
}
It likely doesn't hurt anything but I usually remove it.

Hi Adam Tygart,
Thank you for your quick response. I have made the changes as you have
suggested. I changed
the ttl value to 35 and higher than that .But it didn't work for me.
I have used normal dante client and socksify commadn to push any file from the
machine B to
the remote machine A.I have used proxy machine for this.
Is there any way I can set the proxy server in the gmond.conf file?
Thanks,
Arpita

Arpita,
In my (admittedly limited) experience, the ttl is your issue here. The
ttl (or Time-To-Live) is the number of hops across switches your
packet will survive. In your case, if it is more than one switch in
the chain the packet will get dropped. I tend to raise it to 15-20 if
it is going across my network alone, and to 35 if it is going across
the internet.
