a. In-case of SMPP server unreachable.
Run the below command to check the server port is in listening mode or not
sudo netstat -plunta | grep 8585
- If port 8585 is in listening mode and still the server is unreachable remotely than check the IpTable/UFW rules.
- If port is not in listening state then check the following:-
- Check is the service (smpp-server) running
- check the RabbitMQ queue named as hub-server.service.queue for running consumers.
- If both the above points are working then take the screenshot of the service status and restart the service.
b. In case of server reachable but giving error code -1 / -2 on bind requests
- Check the ESME blacklist rule for preventing any flooding. If the same doesn’t exists than create one.
- Bind Request : Max 4 times per minute
- Enquire link Request : Max 2 times per minute
- Capture live PDU on tcp.port 8585
- Verify SMPP server services Event Viewer log on application portal.
- Take a screenshot of the output of this command
sudo netstat -plunta | grep 8585
- Restart the server service to allow the ongoing traffic.
