Question & Answer
Question
How can you check the ORBLocalPort connectivity from the EMS when the probe does not run?
Cause
The ORBLocalHost and ORBLocalPort define the listener running on the probe server. This port must be available and visible from the EMS server. The EMS sends data to the probes ORBLocalPort.
Answer
Use netcat or the open_socket.pl script to create an open tcp port on the probe server.
Telnet to the listening port from the EMS server to confirm the ORBLocalPort is available.
Example probe property settings.
ORBLocalHost : '192.162.20.20'
ORBLocalPort : 12345
ORBLocalPort : 12345
Example test:
Create listener on the probe server.
nc -l -p 12345
Create listener on the probe server.
nc -l -p 12345
From the EMS use curl to connect to the listeners port.
curl telnet://192.162.20.20:12345
curl telnet://192.162.20.20:12345
With curl and netcat, you can type a message and see this message echoed in the console where netcat is running.
For the perl scripts.
Open listener on the probe server.
./open_socket.pl -h 192.162.20.20 -p 12345
Creating open port on 192.162.20.20 12345
Test connectivity from the EMS.
./port_test.pl 192.162.20.20 12345
Connected to 192.162.20.20 on 12345
./port_test.pl 192.162.20.20 12345
Connected to 192.162.20.20 on 12345
If there is a problem with connectivity, discuss the network and firewall access with the administrators.
