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. 287
