Menu and Configuration Options
We’ve covered the essential elements of the Spider. Its main purpose is to provide OOB access over an IP connection, and this it does quite well. As mentioned, the Spider has an extensive menu of configuration options; here are some of the highlights.
From the SLS Remote Console, there is a button on the top left (Figure 11) that allows you to send a CTRL+ALT+DEL to the host—access that isn’t directly available via an RDC. There is a double-check in this feature: it prompts "Do you really want to send Ctrl+Alt+Delete?" This provides another means for application and server control.

From the left side of the Lantronix menu, there are seven choices, starting with the Home Menu. Lantronix provides options for Remote Control, Virtual Media, User Management, KVM Settings, Device Settings, and Maintenance.
The Remote Control menu (Figure 12) provides options for accessing the Host desktop, the same as you would by clicking Click to open from the main screen. There is also an option for Telnet access to the host, if available and configured.

The Virtual Media functionality demonstrates that the Spider is far more than a simple KVM device. For many motherboards, updating the BIOS may require a floppy disk, a CD-ROM or a USB drive at the host machine; Lantronix provides that option remotely. The floppy drive or CD-ROM drive of the remote machine can be used to upload an image over the IP connection to the host machine.
User Management functionality is what you’d expect. Administrators can control all access levels to key machines via the Spider, through the settings selected here.
The KVM Settings Menu provides options for adjusting the User Console, Keyboard and Mouse settings, and Video settings. The Keyboard, Mouse and Video settings enable specifying the connection types (USB, PS/2) if the default auto option doesn’t correctly detect your components. I used this menu for my Linux server, as I’ll describe shortly.
The User Console menu option has a lot of choices, allowing administrators to configure the appropriate compression levels based on access to the device. The default settings assume LAN bandwidth levels, so compression is minimized to provide the best resolution and display. We’ll discuss this further in the next section.
The Device Settings Menu is another example of the vast array of configurable options delivered by Lantronix for the SecureLinx Spider. There are eight submenus here, enabling network configurations, security and certificate configurations, serial port parameters, as well as options for Network Time Protocol (NTP), LDAP or RADIUS authentication, logging, and SNMP functionality.
Finally, there is the Maintenance submenu, which enables viewing information about the Spider, viewing the Event Log, updating firmware, and triggering a reset of the USB and video ports, or the entire device.
