Enable Secure Sockets Layer (SSL)

HP Web Jetadmin administrators enable SSL by adding a certificate to the HP Web Jetadmin application. This

certificate forces the browser to use the more secure HTTPS protocol when a user accesses the client logon

page. The administrator must enable SSL from the console or host that runs the application by using the

procedure in

Configure HTTPS (Server Certificates or SSL) on page 15. When a remote administrator

accesses Tools > Options > Shared > Network > HTTPS, a message appears stating that certificates can only

be installed from an HP Web Jetadmin client that runs on the console or server that hosts HP Web Jetadmin.

In some environments, SSL is required when an HTTP interface or service is used for communication. In these

cases, SSL can be enabled and enforced by HP Web Jetadmin. SSL provides a high level of assurance

regarding the authentication and encryption of HTTP communication. That is, a user who requests access to

the HP Web Jetadmin Smart Client download can be reasonably assured that the system hosting

HP Web Jetadmin is authentic and the communication between the two systems is encrypted so that it

cannot be easily read by eavesdroppers.

The SSL protocol uses certificates to accommodate both authentication and encryption. HP Web Jetadmin

can generate a signing request that can be used by a certificate authority (CA) to generate a certificate. Using

Tools > Options > Shared > Network > HTTPS, the user can generate a Signing Request.

Once the request has been fulfilled by the CA, the certificate is ready to be installed on HP Web Jetadmin.

Remember, you must be at the application console to use Tools > Options > Shared > Network > HTTPS. Use

Install Certificate to browse and upload the certificate file.

Once the certificate is installed, the HTTP service enforces SSL. Any browser contact with HP Web Jetadmin

should indicate HTTPS on the URL when a certificate is installed. Using Remove Certificate uninstalls the

certificate and SSL is no longer enforced.

Important Points to Remember When Implementing SSL

Client communication with SSL enforced requires one or more of the following considerations.

●

For new server certificates, you must install 2048-bit certificates. Any previously installed 1024-bit

server certificates continue to function correctly.

●

When SSL has been implemented on HP Web Jetadmin with an internal certificate authority (CA), the

CA’s authorizing certificate must be installed in the client browser. If this certificate is not installed in

the client browser the HP Web Jetadmin Smart Client page will fail to load up in SSL mode.

●

Proxy servers tend to use the standard SSL port 443. If the HP Web Jetadmin Smart Client page is being

called through a proxy server, a redirect error may occur. This is due to the URL being redirected to 443

rather than 8443 which is the port used by the HP Web Jetadmin SSL. The workaround for this is to place

the HP Web Jetadmin fully qualified domain name (FQDN) into the browsers exceptions list under

Tools > Internet Options > Connections > LAN Settings > Advanced. This causes the browser to pull

HTTP and HTTPS content directly from the HP Web Jetadmin server.

NOTE: HP Web Jetadmin HTTP and HTTPS port numbers can be customized to something other than

8000 and 8443.

●

When you have implemented SSL on HP Web Jetadmin, a redirect occurs when the browser URL uses

port 8000. Here is an example:

The known URL prior to SSL implementation is http://servername.domain.xxx:8000.

After SSL implementation, HP Web Jetadmin will redirect this to a new URL: https://

servername.domain.xxx:8443.

The URLs shown here use FQDN. In most cases the certificate issued and installed in the

HP Web Jetadmin SSL implementation will contain an FQDN for the host on which HP Web Jetadmin is
