About OP5 System

OP5 utilizes CentOS 6 as the operating system. CentOS is an Enterprise-class Linux Distribution derived from Red Hat Enterprise Linux sources. This means that CentOS 6 is binary compatible with Red Hat Enterprise Linux 6. The OP5 System contain a basic but minimal CentOS server installation as a base. On top of that we add common tools and applications needed by OP5 products. The OP5 System also contain a number of custom, OP5 made tools and applications.

All applications are distributed as RPM packages, and made available for customers on our support web www.op5.com/support and in our yum repositories.

System access

There are three ways to access an OP5 System.

  1. Direct access to console by connecting a monitor and a keyboard
  2. By using SSH (Secure SHell)
  3. By HTTPS using a standard web browser

The portal page

The third way, HTTPS access, is used to access the web interfaces for OP5 products and the OP5 System portal page. You can use the portal page to configure your system, gather information about installed software and retrieve information regarding new patches from OP5 Support web. You find the portal by directing your web browser to the OP5 System, https://<server-address>. The portal page also contains links to any installed OP5 products.

The product logos on the portal page links to the respective products web page.

Console and SSH access

You can also administer the system by SSH. SSH is much like telnet but it is encrypted so that nobody can see or interfere with what you are typing. To use SSH you must install a SSH client software at your computer. Most Linux distributions comes with a SSH client included and there are several SSH clients available free of charge for Microsoft Windows.

We recommend putty that can be found on http://www.chiark.greenend.org.uk/~sgtatham/putty/

An other capable SSH client for Microsoft Windows can be found at http://www.ssh.com/. It is only free for non-commercial use though. This client also includes an interface to transfer files in a secure manner from and to the OP5 server.

You need to access the system via the console or by SSH to install upgrades and patches.

System accounts

To change the configuration of a OP5 System you need to log on. The root account is the superuser of the system and equal to the Administrator account in Windows.

The default password for user root is monitor

You should Change root password as soon as possible after installation to block unauthorized access

Be aware that when you are logged on the system as root you have the power to literally wipe the system out, so be careful and if unsure take a backup before performing any changes (read more on backups: Administrative Tasks).
