Printer Firmware Upgrade and Test File Operation: HP Web Jetadmin uses

 

 

 

this printer port to transfer printer firmware files, test job files, and PJL

 

 

 

configuration files.

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

 

 

 

for By User Data Collections.

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 if there are any discoverable printers on the sending host.

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

 

 

 

database on the same host. Optionally, you can configure HP Web Jetadmin

 

 

 

to communicate with a SQL Server database on a different host.

 

 

 

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

 

 

 

SQL Server database.

 

 

 

 

NOTE: The I/O column represents the communication direction with respect to the HP Web Jetadmin server host. HP Web Jetadmin uses random source ports when communicating with ports on remote IP addresses.

NOTE: HP Web Jetadmin uses ports 7627, 3702, and 3910 internally to communicate with devices. To ensure proper communication, these ports must be kept open for communication directly with the device and with the internal HPWSProAdapter service.

NOTE: HP Web Jetadmin uses Internet Control Message Protocol (ICMP) in the discovery process. HP Web Jetadmin sends an ICMP echo request to determine if the IP is active.

Implement SSL

●Enable Secure Sockets Layer (SSL)

●Important Points to Remember When Implementing SSL

●Configure HTTPS (Server Certificates or SSL)

By default, the HP Web Jetadmin HTTP service runs without certificates. If you add a certificate, the HTTP server runs in HTTPS mode and Secure Sockets Layer (SSL) communication is enforced. In HTTPS mode, the user and the HTTP server are authenticated to one another and the traffic 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 certificates. You must obtain a certificate from a certificate 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 file that you can send to the CA. When the CA sends you a certificate, use the Install Certificate feature to enable HTTPS.

CAUTION: For new server certificates, you must install 2048-bit certificates. Any previously installed 1024- bit server certificates continue to function correctly.
