TCP Access Lists
Within TCP/IP environments, the Ethernet Interface 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 Ethernet Interface.
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.
