TCP Access Lists

TCP Access Lists
Within TCP/IP environments, the Ethernet Interface can restrict
host access to destinations/queues and remote command (e.g.,
rsh, rcmd, remsh, and telnet) execution services. This is done using
an access list similar in function to the Unix .rhosts file.
NOTE: Access list settings are not configurable through the HTML
forms provided with the Ethernet Interface.
To view the current access list on the print server:
1. Start a Telnet session with the Ethernet Interface.
Syntax:
telnet EthernetInterfaceIPaddress
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 Ethernet
Interface 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.
