the
fork()
system call. It can be used by
wait()
or
kill()
to perform actions on the given process.
Port Forwarding
Port Forwarding
creates a ‘tunnel’ through a firewall, allowing users on the Internet access to a service
running on one of the computers on your
LAN
, for example, a Web server, an FTP or SSH server, or other
services. From the outside user’s point of view, it looks like the service is running on the firewall.
PPP
The
Point-to-Point Protocol
is a standard for transmitting network layer datagrams (
IP
packets) over serial
point-to-point links. PPP is designed to operate both over asynchronous connections and bit-oriented
synchronous systems.
PPPoE
Point-to-Point Protocol over Ethernet
(PPPoE) is a specification for connecting the users on a
LAN
to the
Internet through a common broadband medium, such as a single DSL or cable modem line.
PPtP
Point-to-Point Tunneling Protocol
(PPtP) is a technology for creating a
Virtual Private Network
(
VPN
)
within the
Point-to-Point Protocol
(
PPP
). It is used to ensure that data transmitted from one VPN node to
another are secure.
Proxy
A
proxy
is server located between a client application and a real server. It intercepts requests, attempting
to fulfill them itself. If it cannot, it forwards them to the real server. Proxy servers have two main purposes:
improve performance by spreading requests over several machines and filter requests to prevent access
to specific servers or services.
PSK
Pre-Shared Key
(PSK), see
Shared Key
.
Public Key
A
public key
is used in public key cryptography to encrypt a message which can only be decrypted with the
recipient's private or secret key. Public key encryption is also called asymmetric encryption, because it
uses two keys, or Diffie-Hellman encryption. Also see
Shared Key
.
Q
QoS
Quality of Service (QoS) defines the performance properties of a network service, including guaranteed
throughput, transit delay, and priority queues. QoS is designed to minimize
Latency
,
Jitter
,
Packet Loss
,
and network congestion, and provide a way of allocating dedicated bandwidth for high priority network
traffic.
The
IEEE
standard for implementing QoS on wireless networks is currently in-work by the
802.11e
task
