You establish a J-Web session through an HTTP-enabled or HTTPS-enabled Web browser. The HTTPS protocol, which uses 128-bit encryption, is available only in domestic versions of the JUNOS software. To use HTTPS, you must have installed the certificate provided by the device.
When you attempt to log in through the J-Web interface, the system authenticates your username with the same methods used for Telnet and SSH.
The device can support multiple J-Web sessions for a single user who logs in to each session. However, if a single user attempts to launch multiple J-Web windows—for example, by right-clicking a link to launch another instance of a Web browser—the session can have unpredictable results.
If the device does not detect any activity through the J-Web interface for 15 minutes, the session times out and is terminated. You must log in again to begin a new session.
To explicitly terminate a J-Web session at any time, click Logout in the top pane.
