CAUTION Use caution when using this feature. You may lose your ability to communicate with the HP Jetdirect print server if your system is not properly specified in the list, or access through HTTP is disabled. For use of the host access list as a security feature, see Chapter 7. Note By default, hosts with HTTP connections (for example, through the embedded Web server or IPP -- the Internet Printing Protocol) are allowed access to the print server regardless of access control list entries. To disable access by HTTP hosts, clear the checkbox at the bottom of the list. Host systems are specified by their IP addresses or network number. If the network contains subnets, an address mask may be used to identify whether the IP address designates an individual host system or a group of host systems. Examples. See the table of sample entries below: IP Address 192.0.0.0 192.1.0.0 192.168.1.2 Mask 255.0.0.0 255.1.0.0 Description Allow all hosts with network number 192. Allow all hosts on network 192, subnet 1. Allow the host with IP address 192.168.1.2. The mask 255.255.255.255 is assumed and is not required. To add an entry into the access control list, use the IP Address and Mask fields to specify a host, and click (check) the Save checkbox for that entry. Then click Apply. To delete an entry from the list, clear the Save checkbox for that entry. Then click Apply. To clear the entire access control list, clear all Save checkboxes, and click Apply.
