How this book is organized

After introducing SCO® networking concepts and components, this book describes how to:

• Use the network, to log into other machines, share files, and transfer files across the network.

• Administer TCP/IP, including configuring subnets, adding pseudo ttys, configuring anonymous ftp, enabling UUCP over TCP/IP, configuring user equivalence, and troubleshooting the stack.

• Manage and troubleshoot the IPX/SPX protocol stack to provide networking services to other systems, including Novell® servers, running the IPX/SPX protocol stack.

• Configure gateway and routing protocols on your system, and configure the operation of the gated, irdd, and routed routing daemons.

• Create and maintain a distributed database of system names, IP addresses, and other information with the Domain Name Service (DNS). Topics covered include server and client configuration, troubleshooting, and administration.

• Configure the Dynamic Host Configuration Protocol (DHCP), which allows a host on a network to receive configuration parameters (including IP addresses) at boot time.

• Use the Address Allocation Server (AAS) to allocate IP addresses for use by other network services (including PPP and DHCP).

• Manage user and system data across the network, with the Network Information Service (NIS). Topics covered include creating and maintaining NIS maps, creating and administering NIS servers and domains, and troubleshooting NIS.

• Manage TCP/IP networks and network devices with the Simple Network Management Protocol (SNMP) Topics covered include configuration, the Management Information Base, SMUX peers, and using SNMP to monitor and correct network problems.

• Configure TCP/IP to operate over serial lines via either the Point to Point Protocol (PPP) or the Serial Line Interface Protocol (SLIP). Topics covered include authentication, negotiation, gateways, interoperability, and troubleshooting.

• Verify connectivity between sites via the TCP/IP or IPX/SPX protocol stacks with the Node Check Manager. Topics covered include adding and deleting sites from the ping list, altering the interval time, and configuring actions and alerts taken when a node is down.

• Sharing files over the network with the Network File System. Topics covered include mounting, exporting, and enabling NFS® filesystems, NFS troubleshooting, and using the Filesystem Manager.

• Modifying the filesharing capabilities of NFS to mount on an as-needed basis (automount). Topics covered include configuring, administering, and troubleshooting automount configurations.

• Enable remote printing for your users with the remote printing capabilities of TCP/IP. Topics covered include setting up print clients and servers, adding and deleting printers and clients, and interoperating with other releases of lpd.

• Create a networked Calendar database server or client. Topics covered include creating and merging calendar databases, setting up calendar servers and clients, and troubleshooting.

• Synchronize clocks on a local network or on the Internet by using the Network Time Protocol (NTP), or by using the Time Synchronization Protocol (TSP), which enables you to synchronize clocks across multiple networks. Topics covered include creating clients and servers, testing and tuning your time server, and troubleshooting.

• Distribute updated files to a number of sites on your network with the TCP/IP rdist command. Topics covered include writing distribution files and notifying users of new software.

• Install or upgrade software components or the entire operating system across the network. Topics covered include installing products onto or from a remote machine, removing and examining software on a remote machine, initiating an operating system on a client that loads the software from a remote server, and understanding the new software storage object (SSO) product structure.

• Create a networked documentation server or client. Topics covered include serving online help to other machines, receiving online help from a help server, and creating homepages.

SCO OpenServer systems include comprehensive documentation. Depending on which SCO OpenServer system you have, the following books are available in online and/or printed form. Access online books by double-clicking on the Desktop Help icon. Additional printed versions of the books are also available. The Desktop and most SCO OpenServer programs and utilities are linked to extensive context-sensitive help, which in turn is linked to relevant sections in the online versions of the following books. See ``Getting help'' in the SCO OpenServer Handbook.

Release Notes

contain important late-breaking information about installation, hardware requirements, and known limitations. The Release Notes also highlight the new features added for this release.

SCO OpenServer Handbook

provides the information needed to get your SCO OpenServer system up and running, including installation and configuration instructions, and introductions to the Desktop, online documentation, system administration, and troubleshooting.

Graphical Environment Guide

describes how to customize and administer the Graphical Environment, including the X Window System^(TM) server, the SCO® Panner^(TM) window manager, the Desktop, and other X clients.

Graphical Environment help

provides online context-sensitive help for Calendar, Edit, the Desktop, Help, Mail, Paint, the SCO Panner window manager, and the UNIX® command-line window.

Graphical Environment Reference

contains the manual pages for the X server (section X), the Desktop, and X clients from SCO and MIT (section XC).

Guide to Gateways for LAN Servers

describes how to set up SCO® Gateway for NetWare® and LAN Manager Client software on an SCO OpenServer system to access printers, filesystems, and other services provided by servers running Novell NetWare® and by servers running LAN Manager over DOS, OS/2®, or UNIX systems. This book contains the manual pages for LAN Manager Client commands (section LMC).

Mail and Messaging Guide

describes how to configure and administer your mail system. Topics include sendmail, MMDF, SCO Shell Mail, mailx, and the Post Office Protocol (POP) server.
