No active socket messages

Kernel

I am having an issue where after a while of running my program I have a large amount of these messages:

TCP: No active socket on port 65389 (a601a73ip:17000) ``TCP: No active socket on port 541 (a601a73ip:17000) ``TCP: No active socket on port 5009 (a601a73ip:17000) ``TCP: No active socket on port 52822 (a601a73ip:17000) ``TCP: No active socket on port 7435 (a601a73ip:17000) ``TCP: No active socket on port 2041 (a601a73ip:17000) ``TCP: No active socket on port 16000 (a601a73ip:17000) ``TCP: No active socket on port 2910 (a601a73ip:17000) ``TCP: No active socket on port 1521 (a601a73ip:17000) ``TCP: No active socket on port 8181 (a601a73ip:17000) ``TCP: No active socket on port 58080 (a601a73ip:17000) ``TCP: No active socket on port 44443 (a601a73ip:17000) ``TCP: No active socket on port 1088 (a601a73ip:17000)

Now the program is still running, but I would like to get to the bottom of why this is happening. I believe this may occur when I disconnect from a socket, but I am not connected to the network?

Any thoughts would be appreciated.

Hi drowsell, It looks like the CPU is receiving TCP connection requests. These requests are ignored and replied with a RST packet. So nothing will happen.

The message is printed by FreeRTOS_debug_printf(), which is a debug level logging.

I can not say if there is a malicious intruder. Does your device have its own unique MAC address? Is 10.96.26.115 the IP-address of your laptop?

You can also start up WireShark and see what packets are passing by on your LAN.

I’ll look into this and get a little more information. My MAC should be unique. My concern was that this was going to result in a memory leak, but it seems like this is just my device rejecting the connections you said?
