Inventory tools for SME 7.x

OCS Inventory NG Description

Open Computer and Software Inventory Next Generation is an application designed to help a network or system administrator keep track of the computers configuration and software that are installed on the network. Information about Hardware and Operating System are collected. Used with a IT and Asset Management Software such as open source tool GLPI, you will have a powerfull inventory and asset management software with automatic updates of computer configuration, license management, help desk and more.

For more information see http://www.ocsinventory-ng.org/.

GLPI Description

GLPI is the Information Resource-Manager with an additional Administration- Interface. You can use it to build up a database with an inventory for your company (computer, software, printers...). It has enhanced functions to make the daily life for the administrators easier, like a job-tracking-system with mail-notification and methods to build a database with basic information about your network-topology.

For more information see http://www.glpi-project.org/.

Server Installation

Download

You can download this package here. You will also need a few dependencies. If you want to save it directly on your SME Server, you can give these commands at the prompt:

wget http://mirror.contribs.org/smeserver/contribs/sgomez/contribs/inventory/dependencies/ocs_perl_deps.tar.gz
wget http://mirror.contribs.org/smeserver/contribs/sgomez/contribs/inventory/smeserver-inventory-tools-1-2.i386.rpm

Install

First, you need to install the dependencies.

According to your SME Server version, you may also need to install mod_perl

yum install mod_perl

Other Perl dependencies have been packaged in one file for easy downloading. Simply uncompress the tarball and install RPMs using yum:

tar -xzf ./ocs_perl_deps.tar.gz
yum localinstall ./ocs_perl_deps/*.rpm

Finally, you can install OCS Reports and GLPI with the following command:

yum localinstall smeserver-inventory-tools-1-2.i386.rpm

You can ignore the yum-comments signal event post-upgrade and signal-event reboot.

Update

Old RPMs version

Update from old RPMs (smeserver-ocs_inventory_ng and smeserver-glpi) is not possible.

You must uninstall both RPMs first!

If you want to keep your data, you need to uninstall old versions with following commnands:

rpm -e smeserver-glpi --noscripts
rpm -e smeserver-ocs_inventory_ng --noscripts

There are 3 new dependencies, so you need to install them. These RPMs can be found in the Tarball.

tar -xzf ./ocs_perl_deps.tar.gz
yum localinstall ./ocs_perl_deps/*remi*.rpm

And then install the new version with

yum localinstall smeserver-inventory-tools-1-2.i386.rpm

New RPM version

Update from new RPM (smeserver-inventory-tools) is possible.

Use YUM to update:

yum localinstall smeserver-inventory-tools-1-x.i386.rpm

Where "x" is the new version number

Uninstallation

To uninstall OCS Reports and GLPI, just hit the following command:

yum remove smeserver-inventory-tools

You can ignore the yum-comments signal event post-upgrade and signal-event reboot.

To completly remove OCS Reports and GLPI (installation files ; MySQL user+database ; OCS Agent) you will need the following command:

sh /root/OCS_GLPI-Full-Uninstall.sh

You should also uninstall all dependencies if you don't need them anymore...

Client Installation

The client side is available on all platforms. Download the latest client version according to your OS.

After installing the Agent, you should launch it manually to upload your first inventory (as it's updated once per day by default)

OCS Agent for SME Server

The client-side of OCS will already be installed if you install smeserver-inventory-tools.

You should see an inventory of your SME Server in OCS web interface after the RPM install.

If you want to inventory other SME Servers (without installing the server-side and web interfaces), you only need following packages in the dependencies tarball:

• monitor-edid-1.11-1.el4.remi.i386.rpm
• ocsinventory-agent-0.0.6-1.el4.remi.noarch.rpm
• ocsinventory-ipdiscover-1.01-2.el4.remi.i386.rpm

Then edit /etc/ocsinventory-agent/ocsinv.conf and modify following lines:

OCSSERVER=yourdomain.com
OCSTAG=your_tag

And finally launch the first inventory manually:

ocsinventory-agent -s yourdomain.com -t your_tag

OCS Agent for Windows

Download the latest client software, OCSNG_WIN32_AGENT_1.xx_repack.zip, this contains three alternatives, it is suggested you use OcsAgentSetup.exe. See Section 4.1 in the internal OCS help file.

Launch the first inventory by typing the following in the 'execute box':

"C:\Program Files\OCS Inventory Agent\OCSInventory.exe" /server:yourdomain.com /np /debug /tag:your_tag

Wait a few seconds and go to http://your-server/ocs, you should see your computer's inventory, Or just wait a day for the automatic update.

OCS Agent for Linux

For a RPM based distro use the above rpms. For others download the generic linux tar.gz, unpack, and as root, run the setup script.

Mempis 7 required additional perl- packages, use you package management tools to search for the missing dependencies based on the error messages. See Section 4.2 in the internal OCS help file.

The first inventory is launched during install.

OCS Inventory NG Usage

Access

OCS Reports' web interface can be reached at http://your-server/ocs

Before login, please choose your language (flags on the top right corner)
Login : admin
Password: admin

	Warning:
	For security-reasons, change admin's password after your first login, top right icon next to logout!

Inventories can be done from WAN but the web interface is only available from inside your network for security reasons by default. See Sections 5 & 6 in the internal OCS help file for Reporting and Administration help.

IP discovery

IP discovery feature allow OCS Inventory NG to discover all network connected devices on the network. For this, Communication server asks a number of most “active” computers running OCS Inventory NG agent to scan for MAC addresses in their sub network at each run. See Section 7 in the internal OCS help file.

Modifying default behaviour

You may want to override the default IP Discovery behaviour.

To force a computer to ipdiscover, simply open its inventory. Click on Customization icon and update the ipdiscover behaviour.

---

Now choose the IP of selected computer and save your changes.

---

You should now see your modifications.

At this point, ipdiscover will run next time with the agent!

Manually launch the inventory to force ipdiscover or wait a day for the next inventory.

---

Adding networks and devices categories

Now click on Security and go to Config

---

Add you own network/subnet. All fields are mandatory.

---

We can also add categories. Let's do that!

---

Usage

Go back to Security and click on Network information. Now that your network is created, you should see ipdiscover working...

Click on non-inventoried devices.

---

Now all you have to do is registering new devices!

GLPI's web interface can be reached at http://your-server/glpi

Login : glpi

Password: glpi
