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 Security Features. 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 Allow Web Server (HTTP) access 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. Mgmt.

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
Security
Features
.
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
Allow Web Server (HTTP) access
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
Mask
Description
192.0.0.0
255.0.0.0
Allow all hosts with network number 192.
192.1.0.0
255.1.0.0
Allow all hosts on network 192, subnet 1.
192.168.1.2
Allow the host with IP address 192.168.1.2. The mask
255.255.255.255 is assumed and is not required.
