NetWare Concepts

Netstat Displays the status of the routing tables and current network sessions.

Ping Sends a TCP/IP request for an echo packet to another network host to test

network connections.

2.7 NetWare

Novell’s NetWare software allows you to link computers together and provide file and printer sharing. It is

typically used to network DOS-based PCs, but is starting to appear under UNIX and other operating

systems. NetWare is built around file servers, which handle user logins, provide network resources, and

control security. At least one file server, such as a PC or UNIX host, is required in any NetWare

environment. NetWare users typically have to log into a file server to enjoy the networked (shared) benefits.

The Server supports a significant subset of the NetWare functionality, most notably print spooling.

Fileservers can be configured to send queued print jobs to printers attached to the Server. No special

software is required on the fileserver; configuration uses the EZWebCon Configuration software or the

standard PCONSOLE utility. Any user or application that can use NetWare print queues can spool jobs to

the Server.

The Server must periodically query the file servers for pending jobs. To do so, it logs into a file server to

access the print spooler, and will try to connect to all file servers on the local network (subject to access lists,

explained later) to check for such jobs. See Set/Define Server NetWare Loadhost on page 12-43 for more

information.

NetWare support also allows logins from fileservers to the Server (for configuration) and file downloading

(to download the system software at boot time).

2.7.1 Networking

Each NetWare node uses its hardware address as its node ID. In addition, the Server gets all the networking

information it needs from periodic broadcasts sent by NetWare routers on the network. It will learn its own

network number as well as routes to non-local file servers. No further configuration is needed.

The NetWare protocol can use all four Ethernet frame formats. It will listen for all frame formats, and then

use the correct one for the connection. The different frame types are treated as different networks, and thus

each frame type has a different network number. If there is only one frame format in use on the LAN, the

Server will use the network number for that frame type. If there are multiple frame types, limitations to the

NetWare protocol require that the Server use a different network number for each frame type on which it

wants to advertise itself.

The Server can use multiple frame types by creating a new, unique “internal network number” and

advertising itself as a router to the internal network. Any nodes or fileservers that need to communicate with

the Server use this new network number, and treat the Server as a router to that network. If this behavior is

not desired, the Server can be forced to use only one frame type (and thus not need an internal network

number).
