I'm running:

  • Which Aion version?: v0.3.2 - Ama Dablam

Your issue description goes here below. Try to include actual vs. expected behavior and steps to reproduce the issue.

Related to PR: https://github.com/aionnetwork/aion/pull/736

If start the kernel using ./aion.sh --port 140, it will pass the basic port validation but fails to open the socket using port 140. However,

  1. After passing the basic port check, port number 140 is already updated in the config.xml
  2. The kernel keeps running

Example: 

18-12-11 18:09:41.381 INFO  GEN  [main]: loaded block <num=0, root=5fa1a018... l=32>
18-12-11 18:09:41.810 ERROR P2P  [main]: Failed to connect to Socket Address: 0.0.0.0:140, please check your ip and port configration!

port 140 is a predefined port for EMFIS Data Service. Therefore it requires the admin privilege to overwrite the socket binding check. https://www.speedguide.net/port.php?port=140
