freerdp-shadow-cli - Man Page

A utility for sharing a X display via RDP.


freerdp-shadow-cli [/port:<port number>] [/ipc-socket:<ipc-socket>] [/monitors:<0,1,2,...>] [/rect:<x,y,w,h>] [+auth] [-may-view] [-may-interact] [/sec:<rdp|tls|nla|ext>] [-sec-rdp] [-sec-tls] [-sec-nla] [-sec-ext] [/sam-file:<file>] [/version] [/help]


freerdp-shadow-cli can be used to share a running X display like with VNC but by using the RDP instead. It is also possibly to share only parts (rect) of the display.



If this option is set an ipc socket with the path ipc-socket is used instead of a TCP socket.


Set the port to use. Default is 3389. This option is ignored if ipc-socket is used.


Select the monitor(s) to share.


Select rectangle within monitor to share.


Disable authentication. If authentication is enabled PAM is used with the X11 subsystem. Running as root is not necessary, however if run as user only the same user that started freerdp-shadow-cli can authenticate.
Warning: If authentication is disabled everyone can connect.
