TightVNC is handy app based on Virtual Network Computing protocol that allows remote access to PC screen and files. In the past numerous computers at home were uncommon but now remote screen access via LAN or Internet is more interesting to users. The Unix version of TightVNC Viewer can tunnel connections via SSH automatically using local SSH/OpenSSH client installation.While we are used to have graphical output on monitor next to computer, nothing prevents from neatly packing that image and streaming it away by network. The server allows or disallows remote keyboard and mouse events depending on which password was used for authentication.

Support for two passwords, full-control and read-only.

The Java viewer applet can be accessed via built-in HTTP server like in the standard VNC.

TightVNC includes a greatly improved Java viewer with full support for Tight encoding, 24-bit color mode, and more.

Unlike other encodings, Tight encoding is configurable via compression levels and JPEG image quality setting. New Tight encoding is optimized for slow and medium-speed connections and thus generates much less traffic as compared to traditional VNC encodings.

Efficient 'Tight' encoding with optional JPEG compression.
