OUTLINE

• simple, light and easy proxy for X Window (X protocol)
• useful in mobile environment to retain X connectios virtually persistent
• useful where TCP/IP is not reachable from a X client to a X server
• useful where TCP connection establishment for X protocol is slow
• based on a multiplexing and tunneling protocol (Y11/YYMUX protocol)
• Y11 can be relayed by generic proxies as SOCKS or HTTP(SSLtunnel)
• Y11 is hard to be malused to relay other protocols
• available both on Unix and Windows(CYGWIN)
• DeleGate/9.9.7-pre12 and after

USAGE

• DeleGate as a Y11 client (with -Fy11 option) shows the usage.

  :  X proxy on the top of the Y11 protocol           ( - ) {Y11R2} 
  :  Usage:                                          _<   >_
  :
  :    server                                                
  :      serv% delegated -P6010 SERVER=y11                  
  :
  :    client
  :      clnt% delegated -Fy11 serv [remote-command] [: local-command]
  :
  :    proxy
  :      prox% delegated -P6010 SERVER=y11 RELAY=y11
  :
  :    client via proxy
  :      clnt% delegated -Fy11 prox//serv [remote-command] [: local-command]
  :
  :  Note:
  :    remote-command is executed at serv and displayed on the X server at clnt
  :    local-command is executed at clnt and displayed on the X server at serv
  :    generic proxy as SOCKS or SSLTUNNEL can be used to reach a Y11 server
  :    add -fv option before the -Fy11 option to peep the activity of Y11
  :
  :  Example:
  :    clnt% delegated -Fy11 serv xterm
  :    clnt% delegated -Fy11 serv : /usr/X11R6/bin/xeyes
  :    clnt% delegated -Fy11 serv xterm -bg red : xlogo -fg blue
  : /////////////////////////////////////////////////////////////////////
  

• Displaying remote X client on the local X server
  clnt% delegated -Fy11 serv xterm
  
  This is equivalent to the following:
  serv% xterm -display clnt:0.0
  
  
• Displaying local X client on a remote X server
  clnt% delegated -Fy11 serv : xterm
  
  This is equivalent to the following:
  clnt% xterm -display serv:0.0
  
  
• Wrapping with SSL
  serv% delegated -P6010 SERVER=y11 STLS=fcl
  clnt% delegated -Fy11 serv xterm STLS=fsv
  
  
• Adding authentication
  serv% delegated -P6010 SERVER=y11 STLS=fcl AUTHORIZER="-list{user:pass}"
  clnt% delegated -Fy11 serv xterm STLS=fsv MYAUTH="user:pass:y11"
