TCP Access Lists

Within TCP/IP environments, the PrintNet can restrict host access to

destinations/queues and remote command (i.e. rsh, rcmd, remsh and

telnet) execution services. This is done using an access list similar in

function to the Unix .rhosts file.

To view the current access list on the print server:

NOTE: Access list settings are not configurable through the HTML forms

provided with the PrintNet.

1. Start a Telnet session with the PrintNet.

Syntax:

telnet

PrintNetIPaddress

2. Log in as “root” and press ENTER at the password prompt since

there is no password by default (or your password for your home set).

3. List the current access list.

Syntax:

List tcpip

If the list is empty, all hosts have access to the PrintNet services. If there

are entries in the list, only those hosts specified have access to printing

and remote command execution.

To add and delete access list entries, the commands are:

Syntax:

store tcpip tcp access add|del

hostIPaddress

networkaddress

reset

where

hostIPaddress

is the IP address of a TCP/IP host on your network

and

networkaddress

is the address of a subnet on your network.
