why sometimes i cannot connect to ssh server or rdp server over tcpbridge

both ssh server and rdp server will reject the connection if no data received in a time range, but do not actively shutdown the connection before it actually receive data. i.e. 1. a connection has been generated to an ssh or rdp server. 2. wait for several minutes without sending any data. 3. the connection will still be kept. 4. send some data, then ssh or rdp server will shutdown the connection.
and since the tcpbridge generates connections before actually needed <for performance concern and design pattern>, if the connections are targeting an ssh or rdp server, the issue described above may appear. but since tcpbridge can detect broken connections automatically, you just need to retry for several times.
