TCP Access Lists

TCP Access Lists

Within TCP/IP environments, the NIC 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, complete the steps below.

Note	Access list settings are not configurable through the HTML forms provided
	with the NIC.

1.Start a Telnet session with the NIC. Syntax:

telnet P5000LJIPaddress

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 TCP access table entry list is empty, all hosts have access to the NIC 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 adddel 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.

Example:

store tcpip tcp access add 192.75.11.25 store tcpip tcp access add 192.75.12.0 store tcpip tcp access del 192.75.11.25 reset

Note	Although the maximum number of entries in the access list is 10, each
	entry can refer to a network rather than a specific host. This allows all
	hosts on that specified network plus any individual hosts specified in the
	list to have access.
