SSH Client Stream - No notification of remote closed

We have a use case where we need to open an SSH client to a remote host and communicate as a stream - i.e. it's not a command/response.

This works fine with CreateShellStream() and the DataReceived event handles incoming unsolicited data.

However, we're seeing the remote end is sometimes closed (gracefully - we see the FIN/ACK in wireshark), but our local end doesn't get any notification event raised. At worst I was hoping we'd get an ErrorOccured event on either the client or the stream, but nope.

The first we find out is a call to IsConnected returning false - and polling isn't cool.

Is this a deficiency of the library or am I doing something wrong. I'd read the docs... if there were any ;)

Beginne damit, CreateShellStream sowie das bestehende Verhalten von DataReceived, ErrorOccured und IsConnected bei einem ordnungsgemäßen Remote-Schließen nachzuverfolgen. Bestätige, wie der SSH-Client und der Stream den FIN/ACK-Fall behandeln, definiere anschließend eine Benachrichtigung, die das Schließen zuverlässig sichtbar macht, und ergänze eine Abdeckung für dieses Szenario; in der Issue wird keine Quelldatei und kein Test genannt.
