Using Ksplice Uptrack

Command-line interface

uptrack-upgrade

Bring your system up to date by installing the latest available updates.

uptrack-remove id

Removes the update with ID id. If invoked with --all, removes all installed updates.

uptrack-install id

Installs the update with ID id.

uptrack-show

Show a list of the updates that are currently installed.

Enabling automatic updates

The Uptrack client will run periodically (via cron) to check for new updates. In the file /etc/uptrack/uptrack.conf, you can configure Uptrack to automatically install new updates, or just notify you when they are available. To receive new updates from Ksplice Uptrack as soon as they are available, change the autoinstall line to read:

autoinstall = yes

Web status interface

For our customers and free trial users, a web interface is available that allows you to monitor the status of all of your machines, from one central location. Please log in to use it.

Firewalls and Proxy configuration

The Uptrack client communicates to the Uptrack server by connecting to https://updates.ksplice.com:443. You can either make your firewall allow those connections, or configure the Uptrack client to use a proxy server by setting the https_proxy option in /etc/uptrack/uptrack.conf.

Email notifications

When new rebootless updates are available for one of your systems, we'll send an announcement to your technical contact address (you can configure this in the Uptrack web interface).

Graphical interface

Note: This feature is currently only available for Ubuntu 9.04, 9.10, and 10.04 LTS.
If you’d like to see it for your distribution, please contact us.
