UNIX / Linux
UNIX operating systems are built around TCP / IP protocols, and although they all have some similarities, they differ greatly in their ability. This is due to the fact that the additional software and the commercial (or non-commercial) features of the various products that are included with the operating system have changed. Some UNIX versions are major software companies, such as Hewlett Packard, Sun Microsystems, and IBM commercial products. Others are developed and maintained as part of the open source movement where volunteer programmers work in leisure time, usually communicating with their colleagues over the Internet and freely releasing their work to the public. There are a number of different UNIX operating systems that can be downloaded free of charge from the Internet, such as FreeBSD, NetBSD, and Linux.
UNIX is mainly connected to the application server platform and generally to web services such as web, FTP, and e-mail servers. Like Windows, UNIX systems can work simultaneously for both servers and clients.
Open Source Software such as SAMBA File Sharing
Central Login Authentication
File & Services
Network File System (NFS) accesses files and folders on remote computers and manages these files and directories as locals.
LPR / LPD is the primary UNIX print protocol that sends tasks to the printer. The LPR component initiates commands such as print waiting jobs, "betting task" and "sending queues" and responds to the LPD component of the print server
Most Unix operating systems use network services can be individually controlled to increase security.
MAC OS X Server
TCP / IP File Sharing Transferring Macintosh Clients and File with Network File System (NFS) Apple File Protocol 3.0
Mac OS X Server uses open source SAMBA for Windows users SMB file sharing. Network File System (NFS) enables folder availability for UNIX and Linux users
File and Print Services
Mac OS X Server supports native Macintosh, Windows, UNIX, and Linux files sharing. Supported protocols are:
- Apple File Services (AFP 3.0) from any AppleShare client through TCP / IP
- Windows (SMB / CIFS) File Sharing Samba
- Network File System (NFS) for UNIX and Linux File Access
Integrated printing services can spool files to any PostScript-enabled printer via TCP / IP, AppleTalk, or USB. Macintosh clients can use LPR support for Print Center or Desktop Printer Utility to connect to a shared printer. Windows users can use the native SMB / CIFS protocol to connect to a shared printer.
Printing Services for OS X Server
Macintosh and UNIX (LPR / LPD)
Windows (SMB / CIFS)
- Multi-User Architecture and User-Level Access Permissions
- Secure Sockets Layer (SSL) Provides Encrypted and Certified Client / Server Communication
- Secure Shell (SSH) provides encryption and authentication for secure remote management.
- Kerberos Support for Centralized Login Authentication
Customer Support  NetWare 5 with Novell Client has three client platforms: DOS and Windows 3.1x, Windows 95/98, and Windows NT.
You can choose Novell Client for Windows 95/98 and Windows NT to choose from three network protocols: IP, IP and IPX or IPX only.
Central Logon Authentication
File Services NetWare offe offers two mutually compatible file services: Novell Storage Services (NSS) the traditional NetWare file system. Both types of file services allow you to store, organize, manage, access, and download data stored on your network.
The NSS collects all the partition-free free space on all the hard drives associated with the server, as well as NetWare volumes and places it as a storage location. Create NSS volumes from the repository when you are installing the server or later with NWCONFIG.
Novell Distributed Print Services (NDPS) is NetWare's default and preferred printing system. NDPS supports IP based and IPX based printing.
Novell supports public key infrastructure using a public certificate developed by RSA Security built into NetWare 5. ] Windows
Windows 2000 Server:
Windows 3.x, Windows 95, Windows 98, and Windows NT Workstation
Windows 2000 Server supports UNIX, Novell NetWare, Windows NT Server 4.0, and Macintosh. The Windows 2000 computing environment consists of two separate processes: interactive logon authentication for a domain account or a local computer, and network authentication that confirms the user's identity for any network service that a user is trying to access. ] types Windows 2000 supports
Kerberos V5 is used with password or smart card for interactive login. The Kerberos V5 protocol also checks the identity of the user and the network services.
Secure Socket Layer / Transport Layer Security (SSL / TLS) authentication is used when a user attempts to access a secure web server.
File and Printing Services
You can use the Printing Administration Wizard to add and maintain printers in Windows 2000, and you can add file shares with Active Directory management tools. Windows 2000 also offers distributed file services that allow files on more than one server to be used for a single share.
User-level protection protects shared network resources, authenticating users' access to resources. The domain controller provides access to the shared resource by checking whether the username and password are the same as in the user account stored in the network security service provider. Because the security provider maintains a network-wide list of user accounts and passwords, no client computers need to keep a list of accounts.
Shared security protects shared network resources with passwords assigned individually on your computer. For example, you can assign a password to a folder or a locally-attached printer. If other users want to access, you'll need to enter the correct password. If you do not assign a password to a shared resource, all users accessing the network can access this resource.
