Possible SYN flooding on port 41083

[wgstarks]

I’m seeing this entry in my system log at about the same time every morning-

Nov 19 03:19:52 Brunnhilde kernel: TCP: request_sock_TCP: Possible SYN flooding on port 41083. Sending cookies. Check SNMP counters

Is this something I should be worried about?

I used google and found this as one of results:

Thanks. I saw that too but I have no idea how to make the suggested changes inside the docker.

 

It seems that I get the error within about 5 minutes after the binhex-delugevpn docker starts.

Any development on that issue? I'm seeing the same message :

 

Tower kernel: TCP: request_sock_TCP: Possible SYN flooding on port 50113. Sending cookies.  Check SNMP counters.

...in my logs and have no idea how to act on it. Since I'm not _that_ advanced to follow the https://access.redhat.com/solutions/30453 instructions, is there any rookie-friendly way on finding out what can cause these messages?

 

thanks a lot!
