Recommended Security Deployments: SET 1

The HP Jetdirect products denoted by SET 1 do not have any cryptographic security capability. As a

result, a BOOTP/TFTP configuration is recommended as we can specify several control parameters

via the TFTP configuration file. This configuration file allows for a great deal of power with very little

administration overhead once configured. Many customers associate BOOTP/TFTP with UNIX or

Linux environments; however, there are many free BOOTP and TFTP servers for Windows and setup is

fairly easy. An example UNIX configuration will be provided here.

picasso:\

:hn:\

:ht=ether:\

:vm=rfc1048:\

:ha=0001E6123456:\

:ip=192.168.40.39:\

:sm=255.255.255.0:\

:gw=192.168.40.1:\

:lg=192.168.40.3:\

:T144="hpnp/picasso.cfg":\

:T151=”BOOTP-ONLY”:

This configuration provides the following:

• Syslog server: 192.168.40.3

• TFTP configuration file: picasso.cfg under the subdirectory of “hpnp” of the TFTP daemon’s

home directory

• Forces HP Jetdirect to remain with BOOTP and not transition to DHCP if a BOOTP server

is unavailable.

An example of the contents of the TFTP configuration file picasso.cfg:

# Allow subnet 192.168.40.0 access

allow: 192.168.40.0 255.255.255.0

# Disable Telnet

telnet-config: 0

# Disable the embedded Web server

ews-config: 0

# disable unused protocols

ipx/spx: 0

dlc/llc: 0

ethertalk:0

# Set a password

passwd: Security4Me3

# Disable SNMP

# use with caution – breaks SNMP management tools

snmp-config:0

# if SNMP must be enabled, comment out the “snmp-config” command and

# uncomment out the following:

# set-community-name: Security4Me3

# get-community-name: notpublic

# default-get-community: 0

# parameter file
