3 vncs, vncv \- remote frame buffer server and viewer for Virtual Network Computing (VNC)
63 VNC is a lightweight protocol
64 for accessing graphical applications
65 remotely. The protocol allows one or more
66 clients to connect to a server.
67 While connected, clients display the frame buffer
68 presented by the server and can send mouse events,
69 keyboard events, and exchange snarf buffers.
70 The server persists across viewer sessions, so that
71 the virtual application can be accessed from various locations
72 as its owner moves around.
74 VNC displays have names of the form
78 is the machine's network name and
80 is a small integer identifier; display
86 starts a new virtual frame buffer in memory, simulating
87 a Plan 9 terminal running
90 by default an interactive shell.
91 As viewers connect, each is authenticated using a
92 (rather breakable) challenge-response protocol using
93 the user's Inferno/POP password.
100 start TLS on each viewer connection using the certificate
103 The corresponding private key must be loaded into
106 When serving TLS connections, the base port is
107 35729 rather than 5900.
112 without this option, the server searches
113 for an unused display.

160 significantly better matching to the Plan 9 color map.
163 set the ordered list of allowed frame buffer update encodings.

201 If the remote frame buffer is larger than the local screen,
202 only the upper left corner can be accessed.

209 supports only version 3.3 of the RFB protocol.
