Introducing the HP Jetdirect Network Projector Manager
Introduction
The HP Jetdirect network projector manager is a server that connects a
projector directly to a network, so that you can manage it from anywhere on
the network.
Throughout this manual, this product is called a projector server.
Security Protocols
SNMP
SNMP (Simple Network Management Protocol) is used by network
management applications for device management. HP Jetdirect projector
servers support SNMP and standard MIB-II (Management Information Base)
objects on IP networks.
HP Jetdirect projector servers support an SNMP v1/v2c agent, and an
SNMP v3 agent for enhanced security.
HTTPS
HP Jetdirect projector servers support HTTPS (Secure Hyper Text Transfer
Protocol) for secure, encrypted management communications between their
embedded Web servers and your Web browser.
ENWW 5
Authentication
EAP/802.1X Server-Based Authentication
As a network client, the HP Jetdirect projector server support network access
using the Extensible Authentication Protocol (EAP) on an IEEE 802.1X
network. The IEEE 802.1X standard provides a port-based authentication
protocol where a port can allow or block access depending on client
authentication results.
When using an 802.1X connection, the projector server supports Extensible
Authentication Protocol (EAP) with an authentication server, such as a
RADIUS (Remote Authentication Dial In User Service, RFC 2138) server.
Projector servers support the following EAP/802.1X method:
● PEAP (Protected Extensible Authentication Protocol). PEAP is a mutual
authentication protocol that uses digital certificates for network server
authentication and passwords for client authentication. For additional
security, the authentication exchanges are encapsulated within TLS
(Transport Layer Security). Dynamic encryption keys are used for secure
communications.
The network infrastructure device that connects the projector server to the
network (such as an HP Procurve switch) must also support the EAP/802.1X
method used. In conjunction with the authentication server, the infrastructure
device can control the degree of network access and services available to the
server client.
To configure the server for EAP/802.1X authentication, you must access the
embedded Web server through your Web browser. For more information, see

TCP/IP Configuration
Introduction
To operate properly on a TCP/IP network, the HP Jetdirect projector server
must be configured with valid TCP/IP network configuration parameters, such
as an IP address that is valid for your network. For general information on
TCP/IP networks, see Appendix A
Server-Based and Manual TCP/IP Configuration
When in a factory-default state and powered on, the HP Jetdirect projector
server will try to obtain its TCP/IP configuration using a server-based method,
such as BOOTP/TFTP, DHCP/TFTP, or RARP. These server-based methods
are described later in this chapter. Depending on the server model, up to two
minutes may be used for these methods. If configuration is not successful, a
default IP address will be assigned.
The server may also be configured manually. Manual-based tools include a
Web browser, arp and ping commands (when the default IP address is
192.0.0.192), or SNMP-based management software. TCP/IP configuration
values assigned manually will be retained when powered off/on.
.
The server can be reconfigured to use either server-based or manual
configuration of TCP/IP settings at any time.
To identify the IP address that is configured on the projector server at any
time, see the IP address displayed in the projector’s on-screen Help menu.
ENWW 12
Default IP Address
When in a factory-default state (for example, when shipped from the factory
or after a cold-reset), the HP Jetdirect projector server has no IP address. A
default IP address may or may not be assigned depending on the network
environment.
Default IP Address Will Not Be Assigned
A default IP address will not be assigned if a server-based method (such as
BOOTP or DHCP) is successful. And if the server is powered off/on, the same
method will again be used to retrieve IP configuration settings. If this method
now fails to retrieve the IP configuration settings (for example, the BOOTP
or DHCP server is no longer available), a default IP address will not be
assigned. Instead, the server will continue to send IP configuration requests
indefinitely. You must cold-reset the server to change this behavior.
In addition, a default IP address will not be assigned if a network cable is not
attached.
Default IP Address Will Be Assigned
A default IP address will be assigned if the factory-default methods fail, or if
the server has just been reconfigured by an administrator to use a server-based
method (such as BOOTP or DHCP) that fails.
If a default IP address is assigned, the address will depend on the network to
which the server is connected. The server senses broadcast packets on the
network to determine the appropriate default IP settings:
● On small private networks that adhere to automated, standards-based IP
address assignments, the server uses a link-local addressing technique to
assign a unique IP address. Link-local addressing is limited to a local IP
subnet (not routed) and may be referenced as Au to IP. The IP address
assigned will be in the range of 169.254.1.0 to 169.254.254.255
(commonly referenced as 169.254/16). However, it can be further
modified for your network using supported TCP/IP configuration tools if
necessary.
With link-local addresses, subnetting is not used. The subnet mask will
be 255.255.0.0, and cannot be changed.
ENWW TCP/IP Configuration 13
Link-local addresses will not route off the local link, and access to or from
the Internet will not be available. The default gateway address will be the
same as the link-local address.
If a duplicate address is sensed, the HP Jetdirect server will automatically
reassign its address, if necessary, in accordance with standard link-local
addressing methods.
● On large or enterprise IP networks, a temporary address of 192.0.0.192
will be assigned until it is reconfigured with a valid address through
supported TCP/IP configuration tools. We refer to this address as Legacy
Default IP.
● On mixed-environment networks, the self-assigned default IP address
may be either 169.254/16 or 192.0.0.192. In this case, you should verify
through the projector’s on-screen Help menu that the assigned default IP
address is as expected.
The IP address configured on your projector server can be found on the
projector’s on-screen Help menu.
Default IP Address Configuration Options
Default IP Parameter
A Default IP configuration parameter on the projector server controls how the
default IP address is assigned. Whenever the server is unable to obtain an IP
address during a forced TCP/IP reconfiguration (for example, when manually
configured to use BOOTP or DHCP), this parameter will determine the default
IP address to use.
When the server is in a factory-default state, this parameter is undefined.
If the server is initially configured with a default IP address (either a link-local
IP address or the legacy default 192.0.0.192 IP address), the Default IP
parameter will be set to either Auto IP or Legacy Default IP to match.
The Default IP parameter can be changed through a supported configuration
tool, such as a Web browser and SNMP management applications.
ENWW TCP/IP Configuration 14
DHCP Requests Enable/Disable
When a default IP address is assigned, you can configure the projector server
to send, or not send, periodic DHCP requests. DHCP requests are used to
retrieve IP configuration settings from a DHCP server on the network. By
default, this parameter is enabled, allowing DHCP requests to be transmitted.
However, this parameter may be disabled through supported configuration
tools such as a Web browser, and SNMP management applications.
TCP/IP Configuration Tools
When a network connection has been established, an HP Jetdirect projector
server can be configured with valid TCP/IP parameters for your network in
the following ways:
● Using Software. You can use installation, setup, and management
software running on supported systems. For more information see
Chapter 2
● BOOTP/TFTP. You can download the data from a network-based server
using BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer
Protocol) each time the projector is turned on. For more information, see
“U

is accessible by the projector.
, “HP Web Jetadmin”.
sing BOOTP/TFTP”.
● DHCP/TFTP. You can use Dynamic Host Configuration Protocol
(DHCP) and TFTP (Trivial File Transfer Protocol) each time the projector
is turned on. These protocols are supported on HP-UX, Solaris, Linux,
Windows NT/2000/Server 2003, NetWare and Mac OS systems. (Refer
to your network operating system manuals to verify that your server
operating system supports DHCP.) For more information, see “Using
DHCP”.
ENWW TCP/IP Configuration 15
Note Linux and UNIX systems: For more information, see the
bootpd “man” page.
On HP-UX systems, a sample DHCP configuration file
(dhcptab) may be located in the /etc directory.
Since HP-UX presently does not provide Dynamic Domain
Name Services (DDNS) for its DHCP implementations,
HP recommends that you set all projector server lease
durations to infinite. This ensures that server IP addresses
remain static until such time as Dynamic Domain Name
Services are provided.
● RARP. A network-based server can use RARP (Reverse Address
Resolution Protocol) to answer the projector server’s RARP request and
supplying the server with the IP address. The RARP method only allows
you to configure the IP address. For more information, see “U

sing RARP.”
default IP address 192.0.0.192 only) You can use the arp and ping
commands from your system. For more information, see “Using the arp
and ping Commands.”
● Embedded Web server. You can browse to the embedded Web server
on the HP Jetdirect projector server to set configuration parameters. For
more information, see Chapter 4
.
ENWW TCP/IP Configuration 16
Using BOOTP/TFTP
BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol)
provide a convenient way to automatically configure the HP Jetdirect
projector server for TCP/IP network operation. When powered on, the
Jetdirect server sends a BOOTP request message onto the network. A properly
configured BOOTP server on the network will respond with a message that
contains basic network configuration data for the Jetdirect server. The BOOTP
server’s response may also identify a file that contains extended configuration
data for the server. The Jetdirect server downloads this file using TFTP. This
TFTP configuration file may be located on the BOOTP server, or a separate
TFTP server.
BOOTP/TFTP servers are typically UNIX or Linux systems. Windows
NT/2000/Server 2003 and NetWare servers can respond to BOOTP requests.
Windows NT/2000/Server 2003 servers are configured through Microsoft
DHCP services (see “Using DHC
2003 systems may require third-party software for TFTP support. For setup
of NetWare BOOTP servers, refer to your NetWare documentation.
Note If the Jetdirect projector server and BOOTP/DHCP server
are located on different subnets, IP configuration may fail
unless the routing device supports “BOOTP Relay” (allows
the transfer of BOOTP requests between subnets).
P”). However, Windows NT/2000/Server
Why Use BOOTP/TFTP?
Using BOOTP/TFTP to download configuration data has the following
benefits:
● Enhanced configuration control of the HP Jetdirect projector server.
Configuration by other methods are limited to select parameters.
● Ease of configuration management. Network configuration parameters for
the entire network can be in one location.
● Ease of HP Jetdirect projector server configuration. Complete network
configuration can be automatically downloaded each time the server is
powered on.
ENWW TCP/IP Configuration 17
Note BOOTP operation is similar to DHCP, but the resulting IP
parameters will be the same when powered off/on. In
DHCP, IP configuration parameters are leased and may
change over time.
When in its factory-default state and powered on, the HP Jetdirect projector
server will attempt to automatically configure itself using several dynamic
methods, one of which is BOOTP.
BOOTP/TFTP on UNIX
This section describes how to configure the projector server using BOOTP
(Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) services on
UNIX servers. BOOTP and TFTP are used to download network
configuration data from a server to the HP Jetdirect projector server over the
network.
Systems That Use Network Information Service (NIS)
If your system uses NIS, you may need to rebuild the NIS map with the
BOOTP service before performing the BOOTP configuration steps. Refer to
your system documentation.
Configuring the BOOTP Server
For the HP Jetdirect projector server to obtain its configuration data over the
network, the BOOTP/TFTP servers must be set up with the appropriate
configuration files. BOOTP is used by the projector server to obtain entries
in the /etc/bootptab file on a BOOTP server, while TFTP is used to
obtain additional configuration information from a configuration file on a
TFTP server.
When the HP Jetdirect projector server is powered on, it broadcasts a BOOTP
request that contains its MAC (hardware) address. A BOOTP server daemon
searches the /etc/bootptab file for a matching MAC address, and if
successful, sends the corresponding configuration data to the Jetdirect
projector server as a BOOTP reply. The configuration data in the
/etc/bootptab file must be properly entered. For a description of entries,
see “Bootptab File Entries
ENWW TCP/IP Configuration 18
.”
The BOOTP reply may contain the name of a configuration file containing
enhanced configuration parameters. If the HP Jetdirect projector server finds
such a file, it will use TFTP to download the file and configure itself with
these parameters. For a description of entries, see “TFTP Configuration File
Entries.” Configuration parameters retrieved through TFTP are optional.
Note HP recommends that the BOOTP server be located on the
same subnet as the projectors it serves. BOOTP broadcast
packets may not be forwarded by routers unless the
routers are properly configured.

TCP/IP Access Control
allow: netnum [mask]
Makes an entry into the host access list stored on the HP Jetdirect projector server.
Each entry specifies a host or network of hosts that are allowed to connect to the
projector. The format is “allow: netnum [mask]” where netnum is a network number
or host IP address, and mask is an address mask of bits applied to the network
number and host address to verify access. Up to 10 access list entries are allowed.
If there are no entries, all hosts are permitted access. For example,
allow: 192.0.0.0 255.0.0.0 allows hosts on network 192.
allow: 192.168.1.2 allows a single host. In this case, the default mask
255.255.255.255 is assumed and is not required.
allow: 0 This entry clears the host access list.

TCP/IP Other Settings
syslog-config:
Enables or disables syslog server operation on the projector server: 0 disables,
1 (default) enables.
syslog-svr:
(syslog-srv:)
The syslog server’s IP address. It specifies the server that the HP Jetdirect
projector server sends syslog messages to. For more information, see Appendix A
syslog-max:
Specifies the maximum number of syslog messages that can be sent by the
HP Jetdirect projector server on a per-minute basis. This setting allows
administrators to control the log file size. The default is 10 per minute. If set to zero,
the number of syslog messages is not restricted.
syslog-priority:
Controls the filtering of syslog messages sent to the syslog server. The filter
range is 0 to 8, with 0 being the most specific and 8 the most general. Only
messages that are lower than the filter level specified (or higher in priority) are
reported. The default is 8, messages of all priorities are sent. If 0, all syslog
messages are disabled.
syslog-facility:
A code used to identify the source facility of a message (for example, to identify
the source of selected messages during troubleshooting). By default, the
HP Jetdirect projector server uses local user values of local0 through local7 to
isolate individual or groups of projector servers. The default is local0.
slp-config:
Enables or disables the Service Location Protocol (SLP) operation on the projector
server: 0 disables, 1 (default) enables.
slp-keep-alive:
Specifies a time period for the projector server to send multicast packets on the
network to prevent being deleted from network device tables. Some infrastructure
devices, such as switches, may delete active devices from their device tables due
to inactivity on the network. To enable this feature, set a value from 1 to 1440
minutes. Set 0 to disable this feature.
ttl-slp:
Specifies the IP multicast “Time To Live” (TTL) setting for Service Location Protocol
(SLP) packets. The default value is 4 hops (the number of routers from the local
network). The range is 1-15. When set to a -1, multicast capability is disabled.
ipv4-multicast:
Enables or disables the receipt and transmission of IP version 4 multicast packets
by the projector server. 0 disables, 1 (default) enables.

ENWW TCP/IP Configuration 27
Table 3.3 TFTP Configuration File Parameters (4 of 7)
idle-timeout:
The number of seconds that an idle data connection is allowed to remain open.
The acceptable values range from 0 to 3600 (1 hour). If “0” is typed, the timeout
mechanism is disabled. The default is 270 seconds.
user-timeout:
An integer (1..3600) that specifies the number of seconds that your FTP session
can be idle before it will be automatically disconnected. The default is 900 seconds.
0 disables the timeout.
ews-config:
(web:)
Enables or disables the projector server’s embedded Web server to change
configuration values: 0 disables, 1 (default) enables.
tcp-mss:
(subnets-local:)
Specifies the maximum segment size (MSS) that the HP Jetdirect projector server
will advertise for use when communicating with local subnets (Ethernet MSS=1460
bytes or more) or remote subnets (MSS=536 bytes):
0 (default): All networks are assumed to be local (Ethernet MSS=1460 bytes or
more).
1: Use MSS=1460 bytes (or more) for subnets, and MSS=536 bytes for remote
networks.
2: All networks are assumed to be remote (MSS=536 bytes), except the local
subnet.
MSS affects performance by helping to prevent IP fragmentation that may result
in data retransmission.
tcp-msl:
Specifies the maximum segment life (MSL) in seconds. The range is 5 - 120
seconds. The default is 15 seconds.
ENWW TCP/IP Configuration 28
Table 3.3 TFTP Configuration File Parameters (5 of 7)
default-ip:
Specifies the IP address to use when the projector server is unable to obtain an
IP address from the network during a forced TCP/IP reconfiguration (for example,
when powered off/on or manually configured to use BOOTP/DHCP).
DEFAULT_IP: sets the legacy default IP address 192.0.0.192.
AUTO_IP: sets a link-local IP address 169.254.x.x.
The initial setting is determined by the IP address obtained when first powered on.
default-ip-dhcp:
Specifies whether DHCP requests will be periodically transmitted when a legacy
default IP address 192.0.0.192 or link-local IP address 169.254.x.x has been
automatically assigned.
0: Disables DHCP requests.
1 (default): Enables DHCP requests.
dhcp-arbitration:
Specifies the amount of time, in seconds, that the projector server will wait for
DHCP configuration offers. A value from 1 to 10 may be set. The default is 5
seconds.
phone-home-config:
Specifies privacy settings on the projector server during embedded Web server
access. This command controls whether statistical data on product use may be
sent to HP. For HP to collect data, Internet access is required.
2: Prompt the user to allow sending data on initial access to the Networking tab of
the embedded Web server. This is the factory-default and cold-reset value. Once
changed, this value cannot be re-selected.
1: Allows the sending of data to HP without prompting the user.
0: Disables sending data to HP without prompting the user.
web-refresh:
Specifies the time interval (1 – 99999 seconds) for embedded Web server
diagnostic page updates. If set to 0, the refresh rate is disabled.
ENWW TCP/IP Configuration 29
Table 3.3 TFTP Configuration File Parameters (6 of 7)
SNMP
snmp-config:
Enables or disables SNMP operation on the projector server. 0 disables, 1 (default)
enables SNMP.
CAUTION: Disabling SNMP will disable all SNMP agents (SNMP v1, v2, v3) as
well as communications with HP Web Jetadmin. In addition, firmware upgrades
through current HP downloading utilities will be disabled.
get-cmnty-name:
(get-community-name:)
Specifies a password that determines which SNMP GetRequests the HP Jetdirect
projector server will respond to. This is optional. If a user-specified get community
name is set, the server will respond to either a user-specified community name or
the factory-default. The community name must be ASCII characters. The
maximum length is 255 characters.
set-cmnty-name:
(set-community-name:)
Specifies a password that determines which SNMP SetRequests (control
functions) the HP Jetdirect projector server will respond to. The community name
of an incoming SNMP SetRequest must match the server’s “set community name”
for the server to respond. (For additional security, you may limit configuration
access through the server’s host access list). Community names must be ASCII
characters. The maximum length is 255 characters.
auth-trap:
(authentication-trap:)
Configures the projector server to send (on) or not send (off) SNMP authentication
traps. Authentication traps indicate that an SNMP request was received, but the
community name check failed. The default is “on.”
trap-dest:
(trap-destination:)
Enters a host’s IP address into the HP Jetdirect projector server’s SNMP trap
destination list. The command format is:
trap-dest: ip-address [community name] [port number]
The default community name is “public”; the default SNMP port number is “162”.
The port number cannot be specified without a community name.
If a “trap-community-name” command is followed by “trap-dest” commands, the
trap community name will be assigned to those entries unless a different
community name is specified in each “trap-dest” command.
To delete the table, use “trap-dest: 0”.
If the list is empty, the server does not send SNMP traps. The list may contain up
to three entries. The default SNMP Trap Destination List is empty. To receive
SNMP traps, the systems listed on the SNMP trap destination list must have a trap
daemon to listen to those traps.
