Linux – how can i add new user in vnc viewer configuration file…

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

Try TightVNC to connect. It seems to work when the free edition of RealVNC does not. http://www.tightvnc.com/

I've also found that the VNC viewer will konk out when connecting to the Mac if the viewer is not running in millions or full color mode.
