It is recommended to install the VMware Tools before running the AMP setup. After deploying the AMP ova file and starting the VM, you can interrupt the installation process via CTRL+C. This gives you access to the AMP shell. Use the following steps to install VMware Tools on a HPE Aruba AirWave Management Platform appliance:
- From the VMware vSphere Client, open the console to the VM and select VM – Guest – Install/Update VMware Tools;
- Type mkdir -p /media/cdrom
- Mount the CD-ROM via mount /dev/cdrom /media/cdrom
- Copy the installation file cp /media/cdrom/VMwareTools-*.tar.gz /tmp
- Unmount the CD-ROM umount /media/cdrom
- Extract the installation file cd /tmp; tar -zxvf VMwareTools-*.tar.gz
- Run the VMware Tools setup and install script by typing /tmp/vmware-tools-distrib/vmware-install.pl –default (2x hyphen)
The installation will take a few minutes. After the installation is finished you can restart the VM via the command init 6 or reboot.
Check the VMware Tools installation after the reboot by interrupting the AMP installation again and type the command vmware-toolbox-cmd -v. This will give you information about the installed version of VMware Tools.
You can now start the AMP installation again via the command /root/amp-install.
Something completely different in this blog post, so no technical stuff on networking. Last week I visited the Fortinet Global Partner Conference in Las Vegas, NV. Travelling from the Netherlands to Las Vegas and back in 5 days results in a big JET LAG for me!! Not only after the flight from the Netherlands to Las Vegas, but also after the flight back I had some problems with sleeping. I bought and tried to take some extra melatonin. This helps to get you in that “sleepy feeling”, but I still had problems to get to bed during the “regular” hours.
I also like it to listen to music to fall in sleep, but it’s not really helpful when the music keeps playing on all night long. After some toggling on the iPhone I found the Sleep Timer function and the possibility to stop playing music after the Sleep Timer counts back to zero. I tested the functionality successfully with several apps, like Apple Music, Spotify and SoundCloud. I guess more apps will support this functionality. Use the following steps to active the Sleep Timer to stop the music from playing:
- Start playing for favorite music. I used Apple Music, Spotify and SoundCloud;
- Start the “Clock” app;
- Select “Timer” at the bottom;
- Set the duration to keep playing music;
- Select “Stop Playing” as action for “When Timer Ends”;
Like it or not, but it this definitely helped me….
When using Cisco Prime you have the option to configure authentication to a remote AAA server via RADIUS or TACACS+. Today I configured Cisco Prime to use HPE Aruba ClearPass as remote AAA server based on the TACACS+ protocol. The configuration of an AAA server in Cisco Prime is very straightforward. Configure the AAA Mode Setting under Administration / Users / Users, Role & AAA / AAA Mode Settings. The next step involves adding HPE Aruba ClearPass as TACACS+ servers via the option menu Administration / Users / Users, Role & AAA / TACACS+ Servers.
I configured a TACACS+ service in ClearPass with a very basic Enforcement Profile. In the beginning I used the same Enforcement Profile, which I also use to enforce privilege level 15 to switches and routers. Authentication will fail at this point. In the Access Tracker I get the following error message:
Tacacs service=NCS:HTTP not enabled
And the login screen from Cisco Prime shows me the following error message.
I created a new Enforcement Profile and added the TACACS+ service NCS:HTTP to the Enforcement Profile. Now I see an access granted in the Access Tracker, but I still get the same error message on the Cisco Prime website. After some digging in Cisco Prime I noticed that Cisco Prime needs to receive TACACS+ attributes from the AAA server to grant access and assign privileges and tasks to the user.
First you need to get the TACACS+ attributes from the Virtual Domain configuration. In the menu options navigate to Administration \ Users \ Virtual Domains. At the upper right corner you have the option to “Export Custom Attributes”.
These attributes need to be configured in ClearPass. As you notice you also need to configure these attributes if you would like to use RADIUS as authentication protocol. You also need to add the attributes from the user group. Navigate to Administration / Users / Users, Role & AAA / User Groups. Click the “Task List” option next to the User Group you would like to use. I use Root in this example.
The User Group Root contains 194 tasks, which need to be added to the Enforcement Profile in ClearPass. Below you see a snippet from the Enforcement Profile configuration.
To make it easy for you, I exported the Enforcement Profile including all the 194 tasks for the Root User Group. You can download the Enforcement Profile in XML format below. Just import the profile into ClearPass and you are good to go!!!

This post isn’t going to describe what HPE Aruba ClearPass or MobileIron is. And neither will it describe the configuration steps necessary to add MobileIron to ClearPass, but I will give a short summary:
- Add the MobileIron VSP to ClearPass as Endpoint Context Server (CPPM – Administration – External Servers);
- The account on MobileIron needs API rights to enable ClearPass to retrieve information from MobileIron;
This post tells a bit more about an error message I suddenly started to receive in the CPPM Eventy Viewer.
Error: not well-formed (invalid token)
I checked the internet, but I couldn’t find any useful information. I opened a TAC case to look into this error. The TAC engineer told me he had seen this error before, where MobileIron sends invalid token characters to ClearPass. He told me that CPPM does batch processing of the devices and the entire batch fails when CPPM doesn’t understand special characters. He also told me how to see which device is causing the problem.
You have to collect the CPPM logs (CPPM – Administration – Server Manager – Server Configuration – Collect Logs). After you untar the tar.gz file, you should look at the directory “strange string”\PolicyManagerLogs\mdm\MI\mdm-server and you should open the file 0.xml.bak.
Scroll down to the line mentioned in the error message and you will see something like below. I always use Notepad++ to open the file.
CPPM doesn’t understand these special characters in the key. When you start scrolling up, you can determine which device in MobileIron triggers the error message in CPPM.
After I found the device in MobileIron I checked every setting on the device to find the special character, but I couldn’t find one. In the end there was only one solution for me: retire the device. This basically means remove the device from MobileIron and the user needs to reprovision the device in MobileIron. The sync between CPPM en MobileIron was successful again after I retired the device.
Tip of the week: I guess you aren’t always looking at the Event Viewer for errors, so maybe it is useful to configure ClearPass Insight to send a notification if a System Error Event occurs!!!
The previous post showed the steps necessary to enable DLP. This post describes the workflow to configure DLP. I needed DLP to relay outbound messages to a specific mail relay based on header information.
At first I create a DLP rule to define the matching conditions. I match specific header information, which is added to a message by the internal MS Exchange server.
You can match multiple conditions, like subject, recipient, sender, body or attachments and you can also use regular expressions. This makes it very powerful to match specific or multiple characteristics from a message. You can also add exceptions to the DLP rule.
The next steps involves creating a DLP Profile. The DLP profile sets the action, when the DLP rule is matched. You need to specify a default action and you can overwrite is by defining specific actions for specific DLP rules. I create an action to deliver mail to an alternate host. The action can be configured from the DLP profile pane or you can configure the action under the Content Profile Actions. I needed to configure an outbound action, which needs to be created under the Content Profile Action.
I use the above action as default in the DLP Profile and set my scan rule to use the default action.
The DLP profile can be assigned to an IP Policy or Recipient Policy. I need to relay message in the outbound direction, so I create an Outbound Recipient Policy and assign the DLP profile.
