Managing J-Web Sessions

You establish a J-Web session with the routing platform 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 a certificate on the routing platform and enabled HTTPS.

When you attempt to log in through the J-Web interface, the routing platform authenticates your username with the same methods used for Telnet and SSH.

Terminating J-Web Sessions

To explicitly terminate a J-Web session at any time, click Logout in the top pane. You must log in again to begin a new session.

By default, if the routing platform does not detect any activity through the J-Web interface for 24 hours, the session times out and is terminated. For information about changing the idle time limit, see Setting J-Web Session Limits.

Setting J-Web Session Limits

By default, an unlimited number of users can log in to the J-Web interface on a routing platform, and each session remains open for 24 hours (1440 minutes). Using CLI commands, you can limit the maximum number of simultaneous J-Web user sessions and set a default session timeout for all users.

To limit the number of simultaneous J-Web user sessions, enter the following commands:
Range: 1 through 1024. Default: Unlimited
To change the J-Web session idle time limit, enter the following commands:
Range: 1 through 1440. Default: 1440

You can also configure the maximum number of simultaneous subordinate HTTP processes that the routing platform creates in response to user requests.

To configure the maximum number of subordinate httpd processes, enter the following commands:

user@host# edit system services web-management limits

user@host# active-child-process process-limit

The default is 5, and the range is 0 through 32.

For more information about system services statements, see the JUNOS System Basics Configuration Guide.

Viewing Current Users

To view a list of users logged in to the routing platform, select Monitor>System in J-Web and scroll down to the Users section, or enter the show system users command in the CLI. The J-Web page and CLI output show all users logged into the routing platform from either J-Web or the CLI.
