Re: GUI tool to show logged in users, copy/paste not working

disclaimer: It's been a long time since I used unix/linux vnc... I might 
be off.

This totally depents on the server side setup... If the users all get 
their own X11 session by inet.d, then just scan the process list for 
xvnc-executables and their users. if the users all connect to existing 
X11 sessions, it is up to the way these sessions enable vnc and if/how 
the connections are logged. In the end, you can always scan the 
connected sessions (netstat -a) and do an educated guess for the X11/VNC 
sessions.

Between msWindows and X11 there are some differences the way the 
copy-buffers are used. On msWindows there is a sinlge buffer that can 
handle roughly everything (except for the kitchen sink ;-). On unix / 
X11, there are more of these buffers. By head I think there is the 
selection buffer and about 10 cut/copy buffers. All of these can only 
handle ascii text. In the beginning of VNC, there just was no connection 
between the local and remote buffers, except for the keyboard buffer. 
Current handling depends first on the used vnc-server, next on the used 
viewer. Check their documentation for details.
