HP Web Jetadmin 10.3 - Proxy Agents Readme
C:\Program Files\Hewlett-Packard Company\HPWSProxy\HPWSProxy\bin\
●
For a default installation on a 64-bit operating system:
C:\Program Files (x86)\Hewlett-Packard Company\HPWSProxy\HPWSProxy\bin\
NOTE: In many cases, adding an exception or rule to the firewall to allow a specific service also allows
an HP Web Jetadmin discovery to take place. If the additional step of adding ports is required, proceed
to step 2.
2. Add the TCP and UDP ports that the HP WS Pro Proxy Agent service uses to the firewall exception list.
The TCP and UDP port numbers are defined in the following registry entries:
●
For a 32-bit operating system:
HKEY_LOCAL_MACHINE\SOFTWARE\Hewlett-Packard\HPLedmProxyAgent
●
For a 64-bit operating system:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hewlett-Packard\HPLedmProxyAgent
The values of Port and WSTransferPort must be added to the firewall exception list as TCP ports. The
values for Port and WSTransferPort might vary from one host PC to another, depending on the
availability of free ports on the host system. By default, the HP WS Pro Proxy Agent service finds free
ports starting at port 8020.
The value of LEDMDiscoveryPort must be added to the firewall exception list as the UDP port. The value
of LEDMDiscoveryPort is the same as the value the administrator set while installing HP WS Pro Proxy
Agent.
Supported devices
For a complete list of the devices that can be discovered with HP SNMP Proxy Agent and HP WS Pro Proxy
Agent, see the Discovering PC-connected Devices in HP Web Jetadmin white paper. This white paper is
available from the
HP Support Center.
Questions and answers
Question Answer
How do I detect whether a proxy is
installed and which proxy is installed?
You can access Add/Remove Programs to see which proxy is installed, but Add/Remove
Programs might not provide the version of the installed proxy.
Does HP Web Jetadmin use ICMP to
discover devices through HP WS Pro Proxy
Agent?
Yes. HP Web Jetadmin does an initial test on the IP address to determine if it is active.
The hosting system must respond or HP Web Jetadmin cannot discover devices. In some
cases, ICMP can be blocked by a firewall, but should be enabled to ensure that the
discovery works. You can issue a simple Windows command at the administrator
command window to add ICMP to the protocols that the Windows firewall allows. The
following is an example:
"netsh firewall set icmpsetting type = all mode = enable"
CAUTION: Before you issue a Windows command to change the firewall settings, make
sure that you read and understand all the related Windows documentation.
Can I use the /a switch when installing
HP WS Pro Proxy Agent by using MSIEXEC?
No. The installer does not support the /a switch. If you use the /a switch, the
installation fails. You must use the /i switch. For more information about the command
syntax, see
Standalone installation on page 8 and Silent installation on page 9.
