Shengdi closed SSHD-993.
------------------------
Resolution: Done
> an additional connection is created when connect to a sshd server
> -----------------------------------------------------------------
>
> Key: SSHD-993
> URL: https://issues.apache.org/jira/browse/SSHD-993
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.1.0
> Reporter: Shengdi
> Priority: Minor
>
> I used
> SshServer sshd = SshServer.setUpDefaultServer(); to start an sshd server.
>
> When I connect to server with several terminals, and then I keep connect with
> other terminals, then I can probably find the additional ones. This is
> randomly, and most happens after multiple connecting simultaneously or very
> close, then other connect will cause additional connection
> Here is an example,
> I connect with 5 terminals very closely, i found 5 connections with netstat,
> this is correct
> TCP 127.0.0.1:63862 127.0.0.1:12399 ESTABLISHED 44444
> TCP 127.0.0.1:63864 127.0.0.1:12399 ESTABLISHED 42764

> TCP 127.0.0.1:63874 127.0.0.1:12399 ESTABLISHED 42516
> TCP 127.0.0.1:63879 127.0.0.1:12399 ESTABLISHED 41704
> But then connect one more time, then i found two connection established this
> time,
