UNIX Configuration
This chapter explains how to configure the EcoLAN 2000E and your network for use
with TCP/IP communication in various UNIX environments. Setup and installation
procedures are provided for most popular UNIX systems. The EcoLAN 2000E TCP/
IP capability will also operate with lpr spoolers on other systems, and with spooler/
supervisor capabilities that communicate raw print jobs to the Print Server TCP/IP
Port. This port number defaults to 9100, but may be changed to any desired number
using the Telnet utility, SNMP, or the HTML pages accessible via MAP or a Web
Browser.
7. 1 UNIX Configuration Overview
The EcoLAN 2000E can support UNIX TCP/IP printing in two modes:
• Host-based lpd where a supplied line printer daemon is run on one or more
workstations and print data is communicated to the EcoLAN 2000E via a TCP/IP
port or,
• Printer-based lpd where the printer appears as a host running a line printer daemon.
In general, printer-based lpd is easiest to use on BSD UNIX systems, requiring an
entry in the printcap file once the EcoLAN 2000E has its IP information. Some UNIX
System V systems have restrictions on support of remote LPD printers, requiring that
the host-based LPD approach be used. For many operating systems, you have the
option of using host-resident printing or print server-resident printing. Each mode has
certain advantages.
• The host-resident method can print the username and filename on its banner page;
the print server-resident method prints a banner page with the host's name.
• The print server-resident method requires you to configure the printer only one
time, when you install the print server. The host-resident method requires that a
printing daemon be installed on every host that you want to be able to print jobs.
