ERROR Main - Abnormal exit: java.lang.RuntimeException: java.net.SocketException: Permission denied

Issue:-

When using ports range lower than 1024 for SDC/Transformer/Control Hub following error occurs:-

ERROR Main - Abnormal exit: java.lang.RuntimeException: java.net.SocketException: Permission denied

Solution:-

Scenario A:-

• If we are starting service manually then make sure that we are starting the service using root user.

Scenario B:-

• If we are starting the service using systemctl, then make sure following lines are commented in /etc/systemd/system/sdc.service, /etc/systemd/system/dpm.service, /etc/systemd/system/transformer.service

#User=sdc
#Group=sdc

Scenario C:-

• Set the port number higher than 1024

Scenario D:-

• If we can not make any of the above changes, then we would have to make changes from the linux end.

Root Cause:-

• On Unix-based systems, including Red Hat Enterprise Linux, it is not possible to bind to ports under 1024 from applications that are not run by root due to security reasons.
