The 802.11 standard supports several means of client authentication: • A network with No Authentication (Open System) does not screen network users based on their identities and usually involves little more than supplying the correct SSID. • A network using Shared Key authentication provides increased security by requiring users or devices to identify themselves with a static key (a hexidecimal or alphanumeric string). • Server-based (EAP/802.1x) authentication provides significantly stronger security, and is commonly used in enterprise-level networks. A dedicated server verifies the identity of a user or device requesting access to the network before granting that access. Several different wireless authentication protocols are available for use on authentication servers (EAP-MD5, EAP-TLS, EAP-TTLS, LEAP, and PEAP), and a network might have more than one protocol in use. EAP-MD5 uses WEP encryption and all the other EAP mechanisms use dynamic encryption. Note: Server-based authentication protocols must be implemented through the HP PSC embedded Web server. Automatic Private IP Addressing. With APIPA, DHCP clients can self-configure an IP address and subnet mask when a DHCP server isn't available. When a DHCP client boots up, it first looks for a DHCP server in order to obtain an IP address and subnet mask. If the client is unable to find the information, it uses APIPA to automatically configure itself with an IP address from a range reserved especially for Microsoft. The IP address range is 169.254.0.1 through 169.254.255.254. The client also configures itself with a default class B subnet mask of 255.255.0.0. A client uses the self-configured IP address until a DHCP server becomes available. Common Internet File System. This provides network drive letter access to the photo memory card on the AiO device. The user is allowed to read/write files on the network from the AiO device photo memory card. Dynamic Host Configuration Protocol server. This is a server that dynamically manages a pool of IP addresses for use on a network or the Internet. When a user logs into the network he is loaned an IP address for the time he is attached to the network. When a user logs off, the IP address is returned to the pool for use by another device. hp psc 2500 series

Authentication
Authentication verifies the identity of a user or device before
granting access to the network, making it more difficult for
unauthorized users to get at network resources. The 802.11
standard supports several means of client authentication:
A network with No Authentication (Open System) does
not screen network users based on their identities and
usually involves little more than supplying the correct
SSID.
A network using Shared Key authentication provides
increased security by requiring users or devices to
identify themselves with a static key (a hexidecimal or
alphanumeric string).
Server-based (EAP/802.1x) authentication provides
significantly stronger security, and is commonly used in
enterprise-level networks. A dedicated server verifies
the identity of a user or device requesting access to the
network before granting that access. Several different
wireless authentication protocols are available for use
on authentication servers (EAP-MD5, EAP-TLS,
EAP-TTLS, LEAP, and PEAP), and a network might have
more than one protocol in use. EAP-MD5 uses WEP
encryption and all the other EAP mechanisms use
dynamic encryption.
Note:
Server-based authentication protocols must be
implemented through the HP PSC embedded Web
server.
AutoIP (APIPA)
Automatic Private IP Addressing. With APIPA, DHCP clients
can self-configure an IP address and subnet mask when a
DHCP server isn’t available.
When a DHCP client boots up, it first looks for a DHCP server
in order to obtain an IP address and subnet mask. If the client
is unable to find the information, it uses APIPA to
automatically configure itself with an IP address from a range
reserved especially for Microsoft. The IP address range is
169.254.0.1 through 169.254.255.254. The client also
configures itself with a default class B subnet mask of
255.255.0.0. A client uses the self-configured IP address
until a DHCP server becomes available.
CIFS
Common Internet File System. This provides network drive
letter access to the photo memory card on the AiO device.
The user is allowed to read/write files on the network from
the AiO device photo memory card.
DHCP Server
Dynamic Host Configuration Protocol server. This is a server
that dynamically manages a pool of IP addresses for use on
a network or the Internet. When a user logs into the network
he is loaned an IP address for the time he is attached to the
network. When a user logs off, the IP address is returned to
the pool for use by another device.
