2.5.6 TCP/IP Utilities and Commands
The following commands have been added to help TCP/IP usability:
Netstat Displays the status of the routing tables and current network sessions.
Finger Displays users on local and remote hosts. The finger command by itself
will show the users on the RapidPrint 500. If given with a parameter, such
as bob@hydra, it shows information regarding user bob on TCP/IP host
hydra
. The username can be omitted, in which case all the users on the
remote host will be displayed. If the host cannot be reached or accessed,
the finger command fails.
NOTE: To see a list of processes on the RapidPrint 500, issue the command “finger finger.”
2.6 LAT and TCP/IP Connection Methods
Users can “log into” the RapidPrint 500 from either a TCP/IP host (using Telnet or Rlogin) or a
LAT host. For example, if the server’s IP address is 192.0.1.92, a Telnet connection from an IP host
to this address will return the local prompt just as if the user had logged in on a hardwired port.
Also, the server can advertise itself as a “service” to LAT hosts. That is to say, LAT hosts can con-
nect to the server and obtain the local prompt.
Once an incoming (LAT or Telnet) connection has been started, users can use the server as if they
were connected on a local port. They can connect to local services and configure the server.
TCP/IP users then have a convenient way to remotely “manage” the server. Managers can simply
log in and become the privileged user, change server parameters, and log out again.
2.7 NetWare
Novell’s NetWare software provides a way to link computers together and provide file and printer
sharing. It is typically used to network DOS-based PC’s, 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 RapidPrint 500 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
RapidPrint 500. No special software is required on the fileserver; configuration uses the EZCon
Configuration software or the standard PCONSOLE utility. Any users or applications that can use
the NetWare print queues can spool jobs to the RapidPrint 500.
The RapidPrint 500 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 net-
work (subject to access lists, below) to check for such jobs.
NOTE: See Set/Define Server NetWare Loadhost for more information.
