1: Preface
Purpose and Audience
This guide describes how to install, configure, use, and update the SecureLinx Spider
device. It is for users remotely and securely monitoring and control of one target
computer system by one or more remote users.

2: Introduction
This chapter introduces the Lantronix SecureLinx Spider (SLS) line of KVM-over-IP
devices. It provides an overview of the products, lists their key features, and describes
the applications for which they are suited.
The SecureLinx Spider is a distributed KVM-over-IP device designed to remotely and
securely provide monitoring and control of one (target) computer system by one or more
remote users. The remote user (client) accesses the Spider over a local or wide area
network connection using a standard web browser. The Spider provides secure, remote
IP-based access to Keyboard, Video, and Mouse (KVM) on the attached server, and
makes it available to anyone who can access the Spider’s IP address. Spider is an
evolution of the traditional remote KVM switch into a compact package, is light enough to
be cable supported from the back of a server, and takes up no rack space.
There are two models: one with both PS/2 and USB keyboard/mouse interfaces (software
selectable), and one for USB-only systems. The Spider is unique in that it is low-enough
in power consumption to be powered from the attached server. The color-coded plugs on
the ends of the cables for the keyboard, mouse, USB port and video are designed to plug
directly into the target system’s corresponding connectors. An optional external AC/DC
power supply is available.
The Spider differs from other KVM-over-IP switches in several ways. Unlike rack mount
KVM-over-IP switches, the allocation of one Spider per computer allows add-as-you grow
scalability and guarantees non-blocked BIOS-level access to mission-critical servers
regardless of the number of remote users or servers that need access. Also, Spider is
unique in that it uses Lantronix SwitchPort+ technology to incorporate two hardware-
switched Ethernet ports, one for the primary network connection and the second for
daisy-chaining Spiders, or aggregating other Ethernet connections (for example, a
dedicated management LAN port on the controlled system). This provides a cost-
effective solution in environments where numerous cable drops and distance limitations
can be a challenge when adding servers.
Features
Browser based – no client software or special licensing required
Server-powered design – no external power supply required
Attaches directly to the server – zero footprint (no vertical rack space required)
Ideal for small branch offices, campuses, or distributed systems environment
Totally non-blocking and scalable (add 1 host at a time)
Incorporates Lantronix SwitchPort+ technology allowing Spiders to be cascaded
or share a host’s Ethernet connection
No video degradation with long Cat-5 cable runs
Virtual media support (use remote source to boot / install files on host)

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
