Re: Peer-to-peer connections use the --server-port causing the server to hang during startup

[Dan Smith]

I think the membership-port-range determines the port that the server side of 
the TCP socket is listening on.

What I see in your log statement is the port number of the client side of the 
socket (where it says localport=37392). The port for the client side of a 
socket comes from the ephemeral port range configured on your OS - usually 
32768–60999 in linux.

Hi devs,


We have noticed that some peer-to-peer connections use ports outside the
range defined by the membership-port-range (41000-61000) parameter:


[vm1] membership-port-range=41000-61000

[vm1] [debug 2022/05/02 11:15:57.968 CEST server-1 <RMI TCP
Connection(1)-192.168.1.36> tid=0x1a] starting peer-to-peer handshake on
socket Socket[addr=/192.168.1.36,port=49913,*localport=37392*]


Is it expected that peer-to-peer connections use ports outside the above
range?


Also, due to the above behavior, the following bug occurs:
