HP LaserJet 3052 User Manual

							TCP/IP configuration tools
Depending on your all-in-one and operating system, the all-in-one can be configured with valid TCP/
IP parameters for your network in the following ways:
●Using Software—You can use the HP ToolboxFX 
software, or you can use the all-in-one
Embedded Web server by entering the IP address in your Web browser.
● BOOTP—You can download the data from a network-based server using BOOTP (Bootstrap
Protocol) each time the all-in-one is turned on. The BOOTP daemon, bootpd, must be running
on a BOOTP server that is accessible by the all-in-one.
● DHCP—You can use Dynamic Host Configuration Protocol (DHCP). This protocol is supported
in HP-UX, Solaris, Red Hat Linux, SuSE Linux, Windows NT/2000/XP, NetWare and Mac
systems. (Refer to your network operating system manuals to verify that your server operating
system supports DHCP.)
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 lease durations to  infinite. This
ensures that IP addresses remain static until such time as Dynamic Domain Name Services
are provided.
Using DHCP
Dynamic Host Configuration Protocol (DHCP, RFC 2131/2132)  is one of several auto configuration
mechanisms that the all-in-one uses. If you have  a DHCP server on your network, the all-in-one
automatically obtains its IP address from that server.
NOTE DHCP services must be available on the server. Refer to your system documentation
or online help to install or enable DHCP services.
NOTE If the all-in-one and BOOTP/DHCP server  are located on different subnets, IP
configuration may fail unless the routing device allows the transfer of DHCP requests between
subnets.
UNIX systems
For more information about setting up DHCP on UNIX  systems, 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 print server lease durations to  infinite. This
ensures that print server IP addresses remain  static until Dynamic Domain Name Services are
provided.

							Windows systems
The all-in-one supports IP configuration from a Windows NT/2000/XP DHCP server. This section
describes how to set up a pool, or “scope,” of IP addresses that the Windows server can assign or
lease to any requester. When configured for BOOTP  or DHCP operation and powered on, the all-in-
one automatically sends a BOOTP or DHCP request for its IP configuration. If properly set up, a
Windows DHCP server will respond with the print server’s IP configuration data.
NOTE This information is provided as an overview. For specific information or for additional
support, see the information supplied with your DHCP server software.
NOTE To avoid problems resulting from IP addresses that change, HP recommends that all
all-in-one devices be assigned IP addresses with  infinite leases or reserved IP addresses.
Windows NT 4.0 Server
Using DHCP with Windows NT 4.0 Server
To set up a DHCP scope on a Windows NT 4.0 server, perform the following steps:
1. At the Windows NT server, open the Program Manager window and double-click the  Network
Administrator  icon.
2. Double-click the  DHCP Manager icon to open this window.
3. Select  Server  and select  Server Add .
4. Type the server IP address, then click  OK to return to the DHCP Manager window.
5. In the list of DHCP servers, click on  the server you have just added, then select  Scope and
select  Create .
6. Select  Set up the IP Address Pool . In the IP Address Pool section, set up the IP address
range by typing the beginning IP address in the Start Address box and the ending IP address in
the End Address box. Also type the subnet mask for the subnet to which the IP address pool
applies. The starting and ending IP addresses define the end points of the address pool
assigned to this scope.
NOTE If desired, you can exclude ranges of IP addresses within a scope.
7.In the Lease Duration section, select  Unlimited, then select  OK. HP recommends that all all-in-
one devices be assigned infinite leases to  avoid problems resulting from IP addresses that
change. Be aware, however, that selecting an unlimited  lease duration for the scope causes all
clients in that scope to have infinite leases. If you want clients on your network to have finite
leases, you can set the duration to a finite time, but you should configure all all-in-one devices
as reserved clients for the scope.
8. Skip this step if you have assigned unlimited leases in the previous step. Otherwise, select
Scope  and select  Add Reservations  to set up your all-in-one devices as reserved clients. For
164 Chapter 9   Networking ENWW
 
						

							each all-in-one, perform the following steps in the Add Reserved Clients window to set up a
reservation for that all-in-one:
a.Type the selected IP address.
b. Obtain the MAC address or hardware address from the configuration page, and type this
address in the Unique Identifier box.
c. Type the client name (any name is acceptable).
d. Select  Add to add the reserved client. To delete a reservation, in the DHCP Manager
window, select  Scope and select  Active Leases . In the Active Leases window, click on the
reservation you want to delete and select  Delete.
9. Select  Close to return to the DHCP Manager window.
10. Skip this step if you are not planning  to use WINS (Windows Internet Naming Service).
Otherwise perform the following steps when configuring your DHCP server:
a. From the DHCP Manager window, select DHCP Options and select one of the following:
●Scope—if you want Name Services only for the selected scope.
● Global—if you want Name Services for all scopes.
b. Add the server to the Active Options list. From the DHCP Options window, select  WINS/
NBNS Servers (044)  from the Unused Options list. Select  Add, then select  OK. A warning
may appear requesting that you set the  node type. You do this in step 10d.
c. You must now provide the IP address of the WINS server by doing the following:
●Select 
Value, then  Edit Array.
● From the IP Address Array Editor, select 
Remove to delete any undesired addresses
previously set. Then type in the IP address of the WINS server and select  Add.
● Once the address appears in the list of IP addresses, select 
OK. This returns you to
the DHCP Options window. If the address you have just added appears in the list of
IP addresses (near the bottom of the window)  go to step 10d. Otherwise, repeat step
10c.
d. In the DHCP Options window, select  WINS/NBT Node Type (046) from the Unused
Options list. Select  Add to add the node type to the  Active Options list. In the Byte box,
type 0x4 to indicate a mixed node, and select  OK.
11. Click  Close  to exit to Program Manager.

							Windows 2000 Server
To set DHCP on a Windows 2000 Server
To set up a DHCP scope on a Windows 2000 server, perform the following steps:
1. Run the Windows 2000 DHCP manager utility. Click  Start, then select Settings and Control
Panel . Open the  Administrative Tools  folder and run the DHCP utility.
2. In the DHCP window, locate and select your  Windows 2000 server in the DHCP tree. If your
server is not listed in the tree, select  DHCP and click the  Action menu to add the server.
3. After selecting your server in the DHCP tree, click the  Action menu and select  New Scope.
This runs the Add New Scope Wizard.
4. In the Add New Scope Wizard, click  Next.
5. Enter a Name and Description for this scope, then click  Next.
6. Enter the range of IP addresses for this  scope (beginning IP address and ending IP address).
Also, enter the subnet mask. Then click  Next.
NOTE If subnetting is used, the subnet mask defines which portion of an IP address
specifies the subnet and which portion specifies the client all-in-one.
7. If applicable, enter the range of IP addresses within  the scope to be excluded by the server.
Then click  Next.
8. Set the IP address lease duration for your DHCP clients. Then click  Next. HP recommends that
all all-in-one devices be assigned reserved IP  addresses. This can be accomplished after you
set up the scope (see step 11).
9. To configure DHCP options for this scope later, select No  and then click Next. To configure
DHCP options now, select  Yes and click  Next.
a. If desired, specify the IP address of the router (or default gateway) to be used by clients.
Then click  Next.
b. If desired, specify the Domain Name and DNS (Domain Name System) servers for clients.
Click  Next.
c. If desired, specify the Domain Name and DNS (Domain Name System) servers for clients.
Click  Next.
d. Select  Yes to activate the DHCP options now, and click  Next.
10. You have successfully set up the  DHCP scope on this server. Click  Finish to close the wizard.
11. Configure your all-in-one with a reserved IP address within the DHCP scope:
a.In the DHCP tree, open the folder for your scope and select  Reservations.
b. Click the  Action menu and select  New Reservation .
c. Enter the appropriate information in each field, including the reserved IP address for your
all-in-one.
166 Chapter 9   Networking ENWW
 
						

							NOTEThe MAC address for your all-in-one is available on the network
configuration page.
d. Under Supported types, select  DHCP only, then click Add.
NOTE Selecting Both or BOOTP only will result in a configuration through BOOTP
due to the sequence in which the all-in-one initiates configuration protocol requests.
e. Specify another reserved client, or click  Close. The reserved clients added will be
displayed in the Reservations folder for this scope.
12. Close the DHCP manager utility.
NetWare systems
NetWare 5.x servers provide DHCP configuration services for network clients, including your HP all-
in-one. To set up DHCP services on a NetWare server, refer to Novell documentation and support.
To discontinue DHCP configuration
CAUTION Changes to an IP address on your  all-in-one may require updates to all-in-one or
system printing configurations for clients or servers. If you do not want your all-in-o\
ne
configured through DHCP, you must reconfigure the all-in-one with a different configuration
method. You can manually modify the TCP/IP parameters through a supported Web browser
using the embedded Web server, the control  panel, or HP ToolboxFX. If you change to
BOOTP configuration, the DHCP-configured parameters are released and the TCP/IP protocol
is initialized. If you change to Manual configuration, the DHCP-configured IP address is
released and the user-specified IP parameters are used. Therefore, if you manually provide
the IP address, you should also manually set all of the configuration parameters, such
as subnet mask and default gateway.
ENWW Using DHCP 167
 
						

							Using BOOTP
BOOTP (Bootstrap Protocol) provides a convenient way to automatically \
configure the all-in-one for
TCP/IP network operation. When powered on, the all-in-one 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 all-in-one. The BOOTP server’s response may also
identify a file that contains extended configuration data for the print server. The TFTP protocol (which
is not a supported feature for this all-in-one) is required to download this. Thus, the TFTP
configuration file that may be located on the  BOOTP server, or a separate TFTP server will be
ignored. BOOTP servers are typically UNIX  or Linux systems. Windows NT/2000/XP and NetWare
servers can respond to BOOTP requests. Windows NT/2000/XP servers are configured through
Microsoft DHCP services. For setup of NetWare BOOTP servers, refer to your NetWare
documentation.
NOTE If the all-in-one and the 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).
Why use BOOTP?
Using BOOTP to download configuration data has the following benefits:
● Enhanced configuration control of the all-in-one. Configuration by other methods, such as an all-
in-one control panel, are limited to select parameters.
● Ease of configuration management. Network configuration parameters for the entire network
can be in one location.
● Ease of configuration. Complete network configuration can be automatically downloaded each
time the all-in-one is powered on.
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 all-in-one will attempt
to automatically configure itself using several dynamic methods, one of \
which is BOOTP.
168 Chapter 9   Networking ENWW
 
						

							BOOTP on UNIX
This section describes how to configure the print server using BOOTP (Bootstrap Protocol) services
on UNIX servers. BOOTP is used to download network configuration data from a server to the all-in-
one 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 all-in-one to obtain its configuration data over  the network, the BOOTP server must be set up
with the appropriate configuration files. BOOTP is used by the all-in-one to obtain configuration data
located in the /etc/bootptab file on  a BOOTP server. When the all-in-one 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 all-in-one as a BOOTP reply. The configuration data in the /etc/bootptab file
must be properly entered. The BOOTP reply may contain the name of a configuration file containing
optional enhanced configuration parameters. Again, this file  will be ignored by the all-in-one.
NOTEHP recommends that the BOOTP server be located on the same subnet as the all-in-
one it serves.
NOTE BOOTP broadcast packets may not be forwarded by routers unless the routers are
properly configured.
Bootptab file entries
An example of a /etc/bootptab file entry for a networked all-in-one is show\
n below. Note that the
configuration data contains tags to identify the various all-in-one parameters and their settings.
Entries and tags supported are listed in the 
Table 9-5 Tags supported in a BOOTP/DHCP boot file
table.

							About LPD
Line printer daemon (LPD) refers to the protocol and programs associated with line-printer spooling
services that may be installed on various TCP/IP systems.
Some of the widely used systems which are supported by your all-in-one using LPD include:
● Berkeley-based (BSD) UNIX systems
● HP-UX
● Solaris
● IBM AIX
● Linux
● Windows NT/2000/XP
The UNIX configuration examples in this section  show the syntax for BSD-based UNIX systems. The
syntax for your system may vary. See  your system documentation for the correct syntax.
NOTEThe LPD functionality can be used with any host implementation of LPD that complies
with the RFC 1179 document. The process for configuring printer spoolers, however, may
differ. See your system documentation for information about configuring these systems.
The LPD programs and protocol include the following:
Table 9-6   LPD programs and protocols
Program NamePurpose of Program
lprQueues jobs for printing.
lpqDisplays print queues.
lprmRemoves jobs from print queues.
lpcControls print queues.
lpd Scans and prints the files if the specified all-in-one is connected to the system.
If the specified all-in-one is connected to another system, this process forwards the files to
an LPD process on the remote system where the files are to be printed.
