1.5 Configuring a Ksplice Client

The configuration file for both the Ksplice Uptrack client and the enhanced Ksplice client is /etc/uptrack/uptrack.conf. You can modify this file to configure a proxy server, to install updates automatically at boot time, or 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 connection via 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 /etc/uptrack/uptrack.conf:

https_proxy = https://proxy_URL:https_port

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

To make the client install all updates automatically as they become available, set the following entry:

autoinstall = yes


Enabling 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 using yum.

To install updates automatically at boot time, the following entry must appear in /etc/uptrack/uptrack.conf:

install_on_reboot = yes

When you boot the system into the same kernel, the /etc/init.d/uptrack script reapplies the installed Ksplice updates to the kernel.

To prevent the client from automatically reapplying updates to the kernel when you reboot the system, set the entry to:

install_on_reboot = no

To install all available updates at boot time, even if you boot the system into a different kernel, uncomment the following entry in /etc/uptrack/uptrack.conf:

#upgrade_on_reboot = yes

so that it reads:

upgrade_on_reboot = yes
