Modem init string
A series (string) of commands sent by modem software to initialize
the modem. These commands configure the modem's options for
parameters such as error correction, data compression, and flow
control. Init strings are fairly specific to each modem. Not all pro-
grams use init strings. Some use settings files such as Windows
.inf
files.
Point-to-Point Protocol (PPP)
A data link protocol that provides dialup access over serial lines by
encapsulating protocols in specialized packets. These packets can
be used to replace a failed network connection and allow remote
users to log onto the network as if they were in-house.
On Screen Display (OSD)
An alphanumeric, character-based interface for configuring SLK
units. The OSD provides minimal prompting and guidance.
RJ45
Short for Registered Jack 45, an 8-wire connector used commonly
to connect computers onto Local Area Networks (LANs). RJ45 con-
nectors are wider and have more pins than the ubiquitous RJ11
connectors used for connecting telephone equipment.
Secure Sockets Layer (SSL)
A protocol for transmitting private documents over the Internet.
SSL works by using a private key to encrypt data that has been
transferred over the SSL connection.
VNC/OSD Hotkeys
A customized set of preprogrammed escape sequences.
SNMP
Short for Simple Network Management Protocol, a set of protocols
for managing complex networks. SNMP works by sending mes-
sages, called protocol data units (PDUs), to different parts of a net-
work. SNMP-compliant devices, called agents, store data about
themselves in Management Information Bases (MIBs) and return
this data to the SNMP requesters.
Stealth mode
An operating mode that disables the SLK to prevent unauthorized
access.
Subnet
Part of a network that shares a common address component. On
TCP/IP networks, subnets are defined as all devices whose IP
addresses have the same prefix. For example, all devices with IP
addresses that start with
216.254.154
are part of the same sub-
net. Dividing a network into subnets is useful for security and per-
formance. IP networks are divided using a subnet mask.
Turtle mode
An operating mode that disables the SLK when attacked.
Virtual Network Computing (VNC) VNC is remote-control software that lets you view and interact with
one computer using a simple program on another computer any-
where on the Internet. VNC is freely and publicly available.
Web control interface
A graphical interface for configuring SLK units. The web control
interface is browser based and lets you perform configuration activ-
ities by pointing and clicking your mouse.
