VNCTracker 3.2 (Default branch)
Image VNCTracker keeps a list of hosts on various Internet accounts. Rather than email or phone each user whenever you need a current IP address for connecting with VNC, you visit the Web page generated by VNCTracker that shows the updated IP address for that host. It will then build .vnc files to easily start VNC sessions served via HTTP. It supports 'Request Reverse VNC Session' to help with proxies and satellite connections. License: GNU General Public License (GPL) Changes:
Many bug fixes. 'Request VNC' has been added to work with satellite and other one-way connections. This requires the remote PC to check your vnctracker server for a hostname.request file containing the IP to connect to. That initiates the reverse connection. The listening viewer (the requester) needs to have any NAT/gateway/firewall forward TCP 5500 to the listening machine. Image

vncpasswd

vncpasswd(1)						     Virtual Network Computing						      vncpasswd(1)

NAME

       vncpasswd - change the VNC password

SYNOPSIS

       vncpasswd [passwd-file]
       vncpasswd -f

DESCRIPTION

       vncpasswd  allows you to set the password used to access VNC desktops.  Its default behavior is to prompt for a VNC password and then store
       an obfuscated version of this password to passwd-file (or to $HOME/.vnc/passwd if no password file is  specified.)   The  vncserver  script
       runs  vncpasswd	the  first  time you start a VNC desktop, and it invokes Xvnc with the appropriate -rfbauth option.  vncviewer can also be
       given a password file to use via the -passwd option.

       The password must be at least six characters long (unless the -f command-line option is used-- see below), and only the first eight charac-
       ters  are significant.  Note that the stored password is not encrypted securely - anyone who has access to this file can trivially find out
       the plain-text password, so vncpasswd always sets appropriate permissions (read and write only by the owner.)  However,	when  accessing  a
       VNC desktop, a challenge-response mechanism is used over the wire making it hard for anyone to crack the password simply by snooping on the
       network.

OPTIONS

       -f     Filter mode.  Read a plain-text password from stdin and write an encrypted version to stdout.  Note that in filter  mode,  short	or
	      even empty passwords will be silently accepted.

FILES

       $HOME/.vnc/passwd
	      Default location of the VNC password file.

       VNC  was  originally  developed	by the RealVNC team while at Olivetti Research Ltd / AT&T Laboratories Cambridge.  TightVNC additions were
       implemented by Constantin Kaplinsky. Many other people participated in development, testing and support.
