Update your system

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

up2date configuration:
login as root, and issue the following command:

up2date --configure ENTER
select number for "removeSkipList" ENTER
C ENTER

select number for "pkgSkipList" ENTER
C ENTER 
ENTER

What the above command does is it will remove "kernel" from the skip package list, and hence, everything, including the kernel can now be upgraded automatically.


Register with Redhat

rhn_register ENTER

enter a username, password and a valid email address NEXT

Tab Tab NEXT

https://rhn.redhat.com/
sign on with the above created username and password.
Click on the Systems Tab
Click System Entitlements
Select DEMO and click "update entitlements"

Click systems
select the system
you will see !Updates available (more info) [click on more info]
select all the packages and click "update"
click "upgrade packages"
click "Confirm"

Update the server:
login as root, and issue the following command

up2date -u ENTER

If the system says it is busy, try again later.

From next time onwards, all you need to do is remember to issue the up2date -u ENTER command once a week to check and/or after learning that updates are available.
