Port number Type

Inbound (I) or

Outbound (O)

Description

8143 TCP I OXPm Web Services (HTTPS): This is a secure communication port for

HP Open Extensibility Pl

atform (management operations).

8443 TCP I Secure Web Server (HTTPS): HP Web Jetadmin provides a secure HTTPS

listener for the initial client launch, Help content, and device le transfer

operations.

9100 TCP O Printer Firmware Upgrade and Test File Operation: HP Web Jetadmin uses this

printer port to transfer printer rmware les, test job les, and PJL

conguration les.

27892 UDP I Traps Listener: HP Web Jetadmin uses this port for SNMP-based alerts and for

By User Data Collections.

27893 UDP I WS Hello Listener: HP Web Jetadmin monitors this port for incoming WS Hello

packets from the HP WS Pro Proxy Agent software that is installed on hosts in

the enterprise. When HP Web Jetadmin detects a packet, it follows up to

determine whether there are any printers to discover on the sending host. For

more information, see the HP Web Jetadmin 10.4 Proxy Agents Readme. This

document is available from the HP Web Jetadmin

support page (in English).

59113 TCP O Microsoft SQL Server: By default, HP Web Jetadmin installs the SQL Server

database on the same host. Option

ally, you can congure HP Web Jetadmin

to communicate with a SQL Server database on a dierent host.

HP Web Jetadmin uses this port to facilitate communication with a remote

SQL Server database.

The I/O column represents the communication direction with respect to the HP Web Jetadmin server host. HP Web Jetadmin uses

random source por

ts when communicating with ports on remote IP addresses.

HP Web Jetadmin uses ports 7627, 3702, and 3910 internally to communicate with devices. To ensure proper communication, these

ports must be kept o

pen for communication directly with the device and with the internal HPWSProAdapter service.

Open the ports in the Windows rewall by using a batch le

HP Web Jetadmin opens the ports listed in the table to communicate with devices. However, the rewall that you

are using might block the connection and pre

vent HP Web Jetadmin from communicating with the network.

Instead of adding rewall rules for these ports one at a time, you can create a batch le that opens all of the

ports that HP Web Jetadmin require

s for the Windows rewall at one time. For instructions, see the Create a

Batch File to Open HP Web Jetadmin Required Ports in the Windows Firewall white paper. This white paper is

available from the HP Web Jetadmin

support page.

Implement SSL

By default, the HP Web Jetadmin HTTP service runs without certicates. If you add a certicate, the HTTP server

runs in HTTPS mode and Secure Sockets Layer (S

SL) communication is enforced. In HTTPS mode, the user and

the HTTP server are authenticated to one another and the trac between them is encrypted. This adds an extra

layer of security to the Smart Client download and other HTTP transactions.

HP Web Jetadmin does not self-generate certicates. You must obtain a certicate from a certicate authority

(CA). CAs can exist inside or outside of an organization. Many companies have their own CAs. The

HP Web Jetadmin Signing Request feature generates a le that you can send to the CA. When the CA sends you a

certicate, use the Install Certicate feature to enable HTTPS.

IMPORTANT: For new server certicates, you must install 2048-bit certicates. Any previously installed 1024-

bit server certicates

continue to function correctly.
