IPX/SPX
IPX/SPX (Internetwork Packet Exchange/Sequenced Packet Exchange) is a
networking protocol developed by Novell. It was used mainly in Netware envi-
ronments as the general LAN protocol, where TCP/IP has become wide-
spread.
LDAP
On a TCP/ IP network, such as the Internet or an intranet, LDAP (Lightweight
Directory Access Protocol) is a protocol that is used to access a database for
managing environment information and the e-mail addresses of network
users.
LPD/LPR
LPD/LPR (Line Printer Daemon/Line Printer Remote) is a platform-
independent printing protocol that runs over TCP/IP. Originally implemented
for BSD UNIX, its use has spread into the desktop world and is now an
industry standard.
POP Before SMTP
A user authentication method for sending E-mail messages. First, the recep-
tion operation is performed and the user is authenticated by the POP server.
Then, IP addresses where the user was successfully authenticated by the
POP server are permitted to use the SMTP server. This method prevents
third parties without permission to use the mail server from sending mail mes-
sages.
Port 9100
When printing through a network, TCP/IP port number 9100 can be used to
send raw data.
