On the remote host, this is my config:
udp_send_channel {
host = 1.1.1.1
port = 8649
}
On the receiving reporting server I have this:
/* You can specify as many udp_recv_channels as you like as well. */
udp_recv_channel {
mcast_join = 239.2.11.71
mcast_if = eth0
port = 8649
bind = 239.2.11.71
}
/* You can specify as many tcp_accept_channels as you like to share
an xml description of the state of the cluster */
tcp_accept_channel {
port = 8649
}
Not sure if this makes sense. I'm trying to circumvent having to use the
mcast I think. I don't have control over the network between these points
and will probably have little ability to change it.

Can you give an example of your config. Right now my gmetad.conf is
simple:
data_source "Blastoff Cluster" 1.1.1.1
gridname "Blastoff"
all_trusted on
