Install
If you haven’t already, hit the download button above and download the Opmantek Virtual Machine.
The virtual machine comes as an uncompressed .ova (Open Virtual Appliance) package, just over 1GB in size. Unless you have specific needs, we recommend you download the latest build.
A hypervisor is a piece of software used to run virtual machines. Opmantek provides instructions for running our Virtual Machine on most popular hypervisors—but if you’ve never used a hypervisor before, we recommend the free VirtualBox solution, which you can download here.
The specific method of deploying the Opmantek Virtual Machine depends on your hypervisor. This page offers installation guides for VirtualBox and VMware Desktop Applications.
If you are deploying on another hypervisor, please use the appropriate guide:
This guide shows screenshots of the macOS version of VirtualBox (6.1). For Windows and Linux equivalent screenshots, please visit the Opmantek Wiki here.
In VirtualBox, go to File>Import Appliance, and then select the Opmantek Virtual Machine .ova package you just downloaded. Select the Opmantek Virtual Machine once it’s loaded into the left sidebar of the application. Then, click on the yellow “Settings” cog. You will need to change four separate settings to allow the Opmantek Virtual Machine to run correctly. The first setting we’ll change can be found under the System tab. You need to ensure that the hardware clock is in UTC time, as below:
Second, select Display settings, and ensure you have allocated at least 16MB of Video Memory, and that the Graphics Controller is set to “VMSVGA”, as below:
Then, select Storage settings, and ensure that “Use Host I/O Cache” is selected, as below:
Finally, select Network settings, and ensure that Adapter 1 is attached to “Bridged Adaptor”, as below:
Now that you’re all set up, you’re ready to run the Virtual Machine. In VirtualBox, this can be done by clicking the green start arrow.
If the text is too small to read, go to Virtual Box’s View settings and select Scaled Mode, which will allow you to resize the window to your preference.
Please note that when you click within the Virtual Machine, your cursor will disappear and you will not be able to interact with your OS until you press the Host key on your keyboard. By default this key is set to Left Command ⌘ on Mac, <<<>>> on Windows, and <<<>>> on Linux.
Go to File –> Open and select the Opmantek Virtual Machine .ova package you just downloaded. The Virtual Machine should import with all settings automatically.
Ensure that you have granted Accessibility permissions in System Preferences for VMware to allow the Virtual Machine to run properly.
Now that you’re all set up, you’re ready to run the Virtual Machine. In VMWare’s Desktop applications, this is done by pressing the triangular “Play” button.
Congratulations! You should now be running the Opmantek Virtual Machine. You’re almost there. The login screen should have loaded in the Virtual Machine.
The authentication credentials are as follows:
User: root
Password: NM1$88
Enter these details as prompted to initialise the Virtual Machine.
In order to connect to the Opmantek Virtual Machine in your browser, you need to know where it’s located on the network. To determine the Virtual Machine’s IP address, enter the following command and press Return:
ifconfig | grep inet | grep -v inet6 | grep -v "127\.0\.0\.1"
This should return a screen like this:
The “inet” IP address is the location of the Opmantek Virtual Machine on the network—and is the address you’ll use to access the software in your browser. In the above screenshot, that address is 192.168.1.117.
You’re now ready to access the Virtual Machine! Simply enter the inet IP address from the previous step into your browser, and you should be greeted by the Applications Homepage, like below:
You have set up the Opmantek Virtual Machine. The next part of this guide will take you through the Virtual Machine’s brief configuration process—and then you’ll be ready to start working with our software.
Configure
If you haven’t already, hit the download button above and download the Opmantek Virtual Machine.
You will be prompted to log in. The default credentials you will need to use are:
Username: nmis
Password: nm1888
For now, you’re going to want to start with Fault, Event and Performance. Click Get Started to begin.
You will be given the option to change the password you just used to log in. If you do not wish to change the password, simply click “Next”.
For now, the most important settings are the first two: Server Name and NMIS Host.
Choose a your preferred server name (we went with opmantek_Tutorial) and enter the IP address from above as the NMIS Host (this is also the IP currently in your address bar).
The other settings are optional, and you can return to them later. For now, press Save, and then Next.
You will now be prompted to add nodes to your network. You can set a custom name for any node, and enter the IP address, SNMP type and SNMP community.
There are also lists of select Locations and Groups which you can use to classify your nodes. If you don’t see an appropriate Group or Location, don’t worry—you can customise these lists later.
Try adding your router first, and then repeat these steps for as many nodes as you would like.
Then click Save, and then click Next.
Click Restart.
Then click Finish.
You may encounter a Temporary error while the Virtual Machine reconfigures. If this occurs, please wait ten seconds and then refresh the page. The Applications Homepage will reload.
You are now ready to work with Opmantek’s Virtual Machine.
Licensing Applications
Good news! Each of Opmantek’s software modules (excluding opFlow) offer a free time-unlimited 20-node licence. The first time you open each program, you will be given the opportunity to activate a free licence.
Time-limited trials are also available if you want to test the software on a larger network, and licences for running Opmantek’s software modules on larger networks are available on our site.
Once you’re done with our three-part Getting Started Guide, you’re all ready to get started with Opmantek’s software suite. To learn more about our individual applications, follow the links below to begin reviewing our extensive documentation.
