PPPoE (Point-to-Point Protocol over Ethernet) - A network protocol
that connects more than one computer on a LAN to a shared ac-
cess point. The access point may be a DSL (digital subscriber line), a
cable modem, or a wireless connection to the Internet. PPPoE uses
point-to-point protocol (PPP - common for standard dial-up phone
service) together with the Ethernet protocol, thereby allowing mul-
tiple users to have access within a LAN.
Print Server - A network device that is connected to one or more
printers and to client computers over a local network. It can accept
print jobs from the computers and send them to the appropriate
printer(s).
Proxy Server – A special server that aids in client-client, client-server,
and/or server-server communications. A common example is a web
server that acts as the portal for a company’s traffic to the Internet.
Each client has the server IP address listed as the proxy server in their
network settings in order to access the Internet or use email.
QoS (Quality of Service) - How well the network or service is run-
ning. QoS reports on those factors that could effect the health of the
network, such as bandwidth, packet loss, delays, etc.
Remote Access - Accessing data or managing a server or worksta-
tion from a separate system or network. The remote access feature
on the Wireless Space includes the creation of a hostname (essen-
tially, a unique web address name, such as www.wirelessspace.
dyndns.org) that will enable easy management and access to data
stored on the device from a separate network.
SAMBA - Another name for SMB. See SMB/CIFS
SMB/CIFS (Server Message Block/Common Internet File System) -
There are many protocols that a network must implement to assure
proper communication between systems, servers, and devices (such
as printers). In normal operation, a computer requests a shared file
or device managed by a server and the server responds to the de-
mand. SMB/CIFS (also called “Samba”) is a protocol that targets the
level in which applications will ask to share a file or device. SMB/
CIFS is compatible with Linux, Mac, and Windows, meaning that all
three operating systems may reside on the same shared network of
servers and devices.
SMTP Server (Simple Mail Transfer Protocol) - A networking and
Internet standard for email communication via IP addressing. SMTP
is used for outgoing mail, often using port 25.
SOCKS (for Sockets) – A protocol that enables client-client and/or
client-server communication via a proxy server. For example, two
co-workers want to exchange information but one is blocked due
to a firewall. Using the SOCKS Internet protocol, a proxy server will
allow them to communicate.
SPI (Stateful Packet Inspection) - Used in firewall programs, SPI can
monitor a network’s outgoing “packets” to determine which include
requests for responses. The incoming packets (emails, documents,
etc.) that are valid responses are allowed through the firewall. An
administrator may also set firewall traffic parameters using SPI, mak-
ing certain that unwanted packets are not allowed into the network
from the WAN.
SSH Server (Secure Shell) - A secure network protocol to exchange
data between two devices on the same LAN. The communication
occurs with a shell, such as Command Prompt (Windows) or Ter-
minal (Mac).
SSL (Secure Socket Layer) - An encryption protocol that offers secu-
rity in communication over the Internet.
SSID (Server Set Identifier) - The network name of the wireless ac-
cess point. While an SSID contains no built-in security protocol, it
can act as a password when kept hidden from outside traffic.
Static IP (Internet Protocol) - As opposed to DHCP, where the IP
address on a computer may change based upon how the server or
router manages network identities, a static IP rarely varies.
Static Port Forwarding - Configuring port forwarding to handle traffic
through an IP address that does not change. A static address must
be configured on a system in order to properly configure static port
forwarding.
TCP/IP (Transport Control Protocol/Internet Protocol) - TCP is an-
other layer of communication between the Internet and, within
companies or organizations, the Intranet. The TCP breaks down the
information that is being sent then puts it back together on the re-
ceiving end. The IP layer makes certain that the packets reach the
correct address.
Time Machine™ - A backup utility for computers using Mac OS X.
Using incremental backups, Time Machine offers a simple interface
to back up Apple computers on network or desktop attached storage
devices. Users can retrieve single or numerous files that have been
periodically saved.
