CAUTION
Use caution when using the Access Control List. 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 (V.34.xx)
.
Host systems are specified by their IPv4 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.
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

Mgmt. Protocols
This link provides access to management communications and other protocols that affect security.
Web Mgmt.
Use this tab to manage communications with the embedded Web server from Web browsers. This tab
appears only for full-featured print servers.
Secure, encrypted Web-based communication is provided through the Secure HTTP (HTTPS) protocol.
If configured to require HTTPS, the embedded Web server routes HTTPS communications through port
443, the well-known port for HTTPS traffic. Although ports 80, 280, or 631 continue for Internet Printing
Protocol (IPP) use, other non-secure communications (HTTP) are redirected to HTTPS. Redirection of
your browser to use HTTPS may be transparent depending on your browser's capabilities.
By factory default, HP Jetdirect print servers and printers with IPsec support are configured to require
HTTPS only.
Although not recommended, you may choose to accept both HTTPS and HTTP communications that
are not secure by disabling (clearing) the
Encrypt All Web Communication
checkbox.
To support the use of HTTPS communications, a Jetdirect certificate must be installed. A factory-default,
self-signed certificate is pre-installed for initial use. Click the
Configure
button to update the pre-installed
certificate, or to install a new one. For more information, see
Configuring Certificates
.
The minimum encryption strength that will be allowed must be specified when using a Jetdirect
certificate. You may select
Low
(default),
Medium
, or
High
encryption strength. For example, selecting
88
