2: Introduction

Built-in serial RS-232 port can be configured for serial console access or remote dial
in access

Functionality

The Spider contains an embedded web server, dedicated hardware, and control firmware
that:

Captures the video output from the attached computer

Compresses the video and serves it up over the network to a Java applet window
launched by the browser on the user’s system which

Draws a replica of the server’s video output on the user’s monitor. The Java applet
then

accepts keystrokes and mouse movements on the user’s system

recognizes those intended for the target computer

transmits those to the Spider

emulates a physically attached keyboard and mouse to spoof the computer into
thinking the user is sitting next to it
