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)

CentOS Linux release 7(Core)


CentOS software packages update

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

WebPortal

NOTE: The GUI/WebPortal CentOS packages software upgrade shown below is only offered on Tsbc, Tmedia and Tsig product. Tdev Linux server with Toolpack must be upgraded using the Command Line procedure.

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