Access Control Use this tab to display the Access Control List (ACL) on the HP Jetdirect print server. An access control list (or host access list) specifies individual host systems, or networks of host systems, that will be allowed to access the print server and the attached network device. Up to 10 entries can be included on the list. If the list is empty (no hosts are listed), any supported system can access the print server. 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. ENWW Using the Embedded Web Server 149
