3.3 Configuring a Ksplice Uptrack Client

The configuration file for both the Ksplice Uptrack client and the Ksplice Enhanced client is /etc/uptrack/uptrack.conf. You can modify this file to configure a proxy server, to install updates automatically at boot time, and to check for and apply new updates automatically.

If your system is registered with the Ksplice Uptrack repository, the client communicates with the Uptrack server by connecting to https://updates.ksplice.com:443. You can either configure your firewall to allow the connection through port 443, or you can configure the client to use a proxy server. To configure the client to use a proxy server, set the following entry in the /etc/uptrack/uptrack.conf file:

https_proxy = https://proxy_URL:https_port

You receive an e-mail notification when Ksplice updates are available for your system.

To instruct the client to install all updates automatically, as they become available, set the following entry in the /etc/uptrack/uptrack.conf file:

autoinstall = yes

Enabling the automatic installation of updates does not automatically update the Ksplice client itself. Oracle notifies you by e-mail when you can upgrade the Ksplice software by using the yum command.

Setting the autoinstall entry value to yes also installs updates automatically at boot time. When you boot the system, the /etc/init.d/uptrack script reapplies the installed Ksplice updates.

To install all available updates at boot time, uncomment the following entry in the /etc/uptrack/uptrack.conf file:

upgrade_on_reboot = yes

The upgrade_on_reboot setting is not implemented for user-space updates.
