How this book is organized

After introducing SCO OpenServer 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.
