Network Protocol Stacks

–> All involve naming

Lan Manager (LM)

NetBEUI/NetBIOS (uses NetBIOS names, max 15 characters)

IPX/SPX

Localtalk/AppleTalk

TCP/IP (uses hostnames, max 255 characters)

Network Filesystems and URIs

Think about local partition filesystems like FAT and NTFS and EFS4. Now consider how you could connect to a remote share over the network: you’ll need a different kind of filesystem, a network filesystem.

These use URIs, just like HTTP does:

http://servername

The oldest network filesystem (or sharing protocol) you need to worry about is NetBIOS. NetBIOS sharing has been replaced by SMB sharing.

Info
NetBIOS is still alive and well. Remember NetBIOS is the name service: it’s all about using NetBIOS names under Windows. Check your NIC configuration, and you’ll see it likely has NetBIOS over TCP (NBT) enabled. This is necessary for many Windows applications.

 

SMB/Samba/CIFS

Browser path:

smb://servername/sharename/

Server Message Block (SMB)

CIFS: Common Internet File System

CIFS paths:

\\servername\sharename \servername\path\to\share

\\192.168.1.2\Users\Public\Shared

Mapping a drive using a CIFS path:

net use g:  \\server1\share1

Linux version: Samba

NFS

nfs://servername/sharename/

AFP

afp://servername/sharename/

FTP

ftp://servername/sharename/

Even local filesystems can be explored with a web browser:

file:///C:/

Domains and Directories

Workgroups (DOS and Windows for Workgroups)

NT Domains (Windows NT 4)

Network Information System (Yellow Pages) (Unix/Linux)

LDAP/OpenLDAP (DoD/Open Source community)

Novell Directory Services (NDS)

Red Hat Enterprise Directory

Naming: UNC, URI and URL
