7 <glossterm>Access Control List</glossterm>
10 A detailed list of permissions granted to users or groups with respect to file and network
16 <glossterm>Active Directory Service</glossterm>
17 <acronym>ADS</acronym>
19 A service unique to Microsoft Windows 200x servers that provides a centrally managed
20 directory for management of user identities and computer objects, as well as the
21 permissions each user or computer may be granted to access distributed network resources.
22 ADS uses Kerberos-based authentication and LDAP over Kerberos for directory access.
27 <glossterm>Common Internet File System</glossterm>
28 <acronym>CIFS</acronym>
30 The new name for SMB. Microsoft renamed the SMB protocol to CIFS during
31 the Internet hype in the 1990s. At about the time that the SMB protocol was renamed
32 to CIFS, an additional dialect of the SMB protocol was in development. The need for the
33 deployment of the NetBIOS layer was also removed, thus paving the way for use of the SMB
34 protocol natively over TCP/IP (known as NetBIOS-less SMB or <quote>naked</quote> TCP
40 <glossterm>Common UNIX Printing System</glossterm>
41 <acronym>CUPS</acronym>
43 A recent implementation of a high-capability printing system for UNIX developed by
44 <ulink url="http://www.easysw.com/">Easy Software Inc.</ulink>. The design objective
45 of CUPS was to provide a rich print processing system that has built-in intelligence
46 that is capable of correctly rendering (processing) a file that is submitted for
47 printing even if it was formatted for an entirely different printer.
53 <glossterm>Domain Master Browser</glossterm>
54 <acronym>DMB</acronym>
56 The Domain Master Browser maintains a list of all the servers that
57 have announced their services within a given workgroup or NT domain.
62 <glossterm>Domain Name Service</glossterm>
63 <acronym>DNS</acronym>
65 A protocol by which computer hostnames may be resolved to the matching IP address/es.
66 DNS is implemented by the Berkeley Internet Name Daemon. There exists a recent version
67 of DNS that allows dynamic name registration by network clients or by a DHCP server.
68 This recent protocol is known as dynamic DNS (DDNS).
73 <glossterm>Dynamic Host Configuration Protocol</glossterm>
74 <acronym>DHCP</acronym>
76 A protocol that was based on the BOOTP protocol that may be used to dynamically assign
77 an IP address, from a reserved pool of addresses, to a network client or device.
78 Additionally, DHCP may assign all network configuration settings and may be used to
79 register a computer name and its address with a dynamic DNS server.
84 <glossterm>Group IDentifier</glossterm>
85 <acronym>GID</acronym>
87 The UNIX system group identifier; on older systems, a 32-bit unsigned integer, and on
88 newer systems, an unsigned 64-bit integer. The GID is used in UNIX-like operating systems
89 for all group-level access control.
94 <glossterm>Key Distribution Center</glossterm>
95 <acronym>KDC</acronym>
97 The Kerberos authentication protocol makes use of security keys (also called a ticket)
98 by which access to network resources is controlled. The issuing of Kerberos tickets
104 <glossterm>Lightweight Directory Access Protocol</glossterm>
105 <acronym>LDAP</acronym>
108 The Lightweight Directory Access Protocol is a technology that
109 originated from the development of X.500 protocol specifications and
110 implementations. LDAP was designed as a means of rapidly searching
111 through X.500 information. Later LDAP was adapted as an engine that
112 could drive its own directory database. LDAP is not a database per
113 se; rather it is a technology that enables high-volume search and
114 locate activity from clients that wish to obtain simply defined
115 information about a subset of records that are stored in a
116 database. LDAP does not have a particularly efficient mechanism for
117 storing records in the database, and it has no concept of transaction
118 processing nor of mechanisms for preserving data consistency. LDAP is
119 premised around the notion that the search and read activity far
120 outweigh any need to add, delete, or modify records. LDAP does
121 provide a means for replication of the database to keep slave
122 servers up to date with a master. It also has built-in capability to
123 handle external references and deferral.
128 <glossterm>Local Master Browser</glossterm>
129 <acronym>LMB</acronym>
131 The Local Master Browser maintains a list of all servers that have announced themselves
132 within a given workgroup or NT domain on a particular broadcast isolated subnet.
137 <glossterm>Media Access Control</glossterm>
138 <acronym>MAC</acronym>
140 The hard-coded address of the physical-layer device that is attached to the network.
141 All network interface controllers must have a hard-coded and unique MAC address. The
142 MAC address is 48 bits long.
147 <glossterm>NetBIOS Extended User Interface</glossterm>
148 <acronym>NetBEUI</acronym>
150 Very simple network protocol invented by IBM and Microsoft. It is used to do NetBIOS
151 over Ethernet with low overhead. NetBEUI is a non-routable protocol.
156 <glossterm>Network Address Translation</glossterm>
157 <acronym>NAT</acronym>
159 Network address translation is a form of IP address masquerading. It ensures that internal
160 private (RFC1918) network addresses from packets inside the network are rewritten so
161 that TCP/IP packets that leave the server over a public connection are seen to come only
162 from the external network address.
167 <glossterm>Network Basic Input/Output System</glossterm>
168 <acronym>NetBIOS</acronym>
170 NetBIOS is a simple application programming interface (API) invented in the 1980s
171 that allows programs to send data to certain network names. NetBIOS is always run over
172 another network protocol such as IPX/SPX, TCP/IP, or Logical Link Control (LLC).
173 NetBIOS run over LLC is best known as NetBEUI (the NetBIOS Extended User Interface
174 &smbmdash; a complete misnomer!).
179 <glossterm>NetBT</glossterm>
180 <acronym>NBT</acronym>
182 Protocol for transporting NetBIOS frames over TCP/IP. Uses ports 137, 138, and 139.
183 NetBT is a fully routable protocol.
188 <glossterm>NT/LanManager Security Support Provider</glossterm>
189 <acronym>NTLMSSP</acronym>
191 The NTLM Security Support Provider (NTLMSSP) service in Windows NT4/200x/XP is responsible for
192 handling all NTLM authentication requests. It is the front end for protocols such as SPNEGO,
193 Schannel, and other technologies. The generic protocol family supported by NTLMSSP is known as
194 GSSAPI, the Generic Security Service Application Program Interface specified in RFC2078.
199 <glossterm>Server Message Block</glossterm>
200 <acronym>SMB</acronym>
202 SMB was the original name of the protocol spoken by Samba. It was invented in the 1980s
203 by IBM and adopted and extended further by Microsoft. Microsoft renamed the protocol to
204 CIFS during the Internet hype in the 1990s.
209 <glossterm>The Simple and Protected GSS-API Negotiation</glossterm>
210 <acronym>SPNEGO</acronym>
212 The purpose of SPNEGO is to allow a client and server to negotiate a security mechanism for
213 authentication. The protocol is specified in RFC2478 and uses tokens as built via ASN.1 DER.
214 DER refers to Distinguished Encoding Rules. These are a set of common rules for creating
215 binary encodings in a platform-independent manner. Samba has support for SPNEGO.
