Updating CentOS / Ubuntu servers.
« on: July 07, 2011, 11:56:55 AM »
Hi,

I had a few questions come in recently about security advisories that come out for CentOS / Ubuntu and how to keep your server protected. Generally the advisories that come out from either the vendor or a security provider have already been submitted to the vendors for review and patching. If a security advisory does come out and lists potential vulnerabilities for software you use there will more than likely already be a patched version sitting on their repositories. Keeping your server up to date is pretty easy on both systems:

CentOS: "yum update"
Ubuntu: "apt-get update"

Both of these commands tell the package manager of the respected distributions to look for updates for the packages it has installed. It will automatically download and install them for you. I know this is pretty trivial to most linux admins but there are some that do not keep their servers updated because they were not informed enough to do so. If you have issues keeping your server up to date, need assistance, or would like it done automatically we do provide those type of services here as well, just let us know and we'll help you out.
