TelcoBridges repository

The operating system (CentOS) software upgrade is performed using yum software package manager. The repositories sites providing RPM packages are configured from /etc/yum.repos.d/. TelcoBridges provides a modified CentOS repository copy (http://repo.telcobridges.com) of the official CentOS repository.

If the unit or Linux server does not have access to Internet (or does not have DNS configured), you should configure an offline CentOS repository on your local machine as explained in the section bellow.

Offline repository configuration

First, SSH to your unit do determine which version of the OS your system is using:

# cat /etc/redhat-release

CentOS release 5.11 (Final)

Configure a local offline Repository for CentOS5

CentOS Linux release 7(Core)

Configure a local offline Repository for CentOS7

CentOS software packages update

The operator can use one of the two methods available: GUI/WebPortal or command line interface.

WebPortal

To upgrade CentOS software packages, follow this procedure from the web interface of the unit:

Hosts -> Status -> TBxxxxxx -> Action -> Upgrade Linux Packages, then 'Apply Action':

When the upgrade is in progress, there is no status shown, and you will see the screen like this:

It may take a while 8-10 mins. You need to refresh the page until you see this:

Once complete, you need to reboot the host: Hosts -> Status -> TBxxxxxx -> Action -> Shutdown -> Reboot

Command line

Alternatively, you can ssh to the unit and run the following command:

# yum clean all
# yum update
# yum group update

Reboot the unit

# reboot
