How to update your system
Updating your system regularly is the first step in securing your server. You didn’t think of this did ya?

login as root, and issue the following command:
Code:
up2date –configure ENTER
select number for “removeSkipList” ENTER
C ENTER
Code:
select number for “pkgSkipList” ENTER
