TCP Access Lists
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 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.
