node doesn't send data

[stage]

I’m experimenting with distributed monitoring servers.

With 3 nodes 1 master and two clients all zabbix 1.6.6 and all in the same network

NodeID=1(Master)10.100.100.53
NodeID=2(client)10.100.100.50
NodeID=3(client)10.100.100.51

Node=3 doesn’t wand to send any info to the master server.

For both clients I have used the same installation procedure, I’m 100% sure that I didn’t do any thing deferent.

For master
Zabbix_server –n 1 –c /etc/zabbix/zabbix_server.conf
For client 1
Zabbix_server –n 2 –c /etc/zabbix/zabbix_server.conf
For client 2
Zabbix_server –n 3 –c /etc/zabbix/zabbix_server.conf

In the GUI of the two clients I made the master server master type and in the master GUI I made the two clients remote type with the right IP ref. I multi checkt.

In the log file of master node I can see the receiving from node2 but not from node 3
In the log file of node2 I can see the node sending to node1.
I can’t see any log of sending in node3.

It would be great if you could help me.

"I can’t see any log of sending in node3."

Isn't that agent complaining with some error? It should say something helpful.
Check if binaries/conf files permissions are the same for node 2 and 3.
