Answer : To upgrade your serverís Kernel please contact email@example.com, or fill out a new ticket over their secure server, with your server name, IP address and root password. InterServer offers free kernel upgrades on their dedicated servers. In order for an upgrade to be complete a server reboot must be done. If you do not wish to have your server rebooted by Interserver after the upgrade please mention that in the ticket.
If you are familiar with the process then only it is advisable to do your own kernel upgrades because If upgrade is done incorrectly your server can be rendered unbootable.
Interserver kernels are compiled with grsecurity. This added protection is available at no additional charge. A security project at http://grsecurity.net sponsored by InterServer. Please do not forget to mention in a ticket if you wish to opt for grsecurity.
