Just joined. Not sure where to ask this question. It relates to security and opening ports on a firewall through which the Spice clients and server would communicate. I would like to know how many ports will need to be opened on a firewall to support the 6 communications channels between the Spice clients and server. Excerpt from Spice for Newbies PDF. -------------------------------------------------------- 2.3.2.1 Channels The client and server communicate via channels. Each channel type is dedicated to a specific type of data. Each channel uses a dedicated TCP socket...... The available channels are: o Main - implemented by RedClient (see above). o DisplayChannel - handles graphic commands, images and video streams. o InputsChannel - keyboard and mouse inputs. o CursorChannel - pointer device position, visibility and cursor shape. o PlaybackChannel - audio received from the server to be played by the client . o RecordChannel - audio captured on the client side. -------------------------------------------------------- After looking at the Spice PDFs it appears to me that 6 ports would need to be opened although the default Spice server port appears to be 5930 (just one port and not six). I would like to know how many ports are required (listening) on the Spice server to handle all 6 channels (TCP sockets)? I am assuming each channel (TCP socket) requires its own port on the Spice server. Thanks, Rich
