CHAPTER 2 UNIX NETWORK CONFIGURATION (TCP/IP)
2-16
IP Security
Brother print servers provide a means of allowing only host computers with
authorized IP addresses to access the print server. This is very useful for
applications where general access to the printer is not allowed. The console
command SET IP ACCESS ENABLED ipaddress enters a host
computer IP address into the access table of the print server (where
ipaddress is the IP address of the host computer; refer to Appendix A for
information on using the print server console). To remove an IP address,
use the command SET IP ACCESS DISABLED ipaddress. To re-
enable general access, use the command SET IP ACCESS ALL.
Raw TCP ports
The Brother range of print servers provide a raw TCP port capability that
can be used by any application that can open and send data to a TCP port.
The port number is 9100 (238C hex). The ports pass data through
unmodified, so there is no TELNET interpretation provided. When using
the raw TCP ports, make sure that TELNET interpretation is disabled in
your software or else you may get distorted printouts.
If you need a different TCP port number or if you want additional TCP
ports, you may define a TCP port number on any service by using the
console command:
SET SERVICE servicename TCP nn
where
servicename
is the name of the service, and nn is the desired port
number (must be greater than 1023). Refer to Appendix A for information
on using the console.
