Configuring EVE-NG on VMware

After a successful install of EVE-NG (as a guest) on VMware Server 5.1, a couple of notes:

  • EVE-NG as a virtual machine requires Intel VT enabled on the host you install it on this can be configured from the BIOS of the host. You can verify the enablement by going to the following URL on the ESX host:

    CTRL+F for nestedHVSupported
  • You need to enable CPU VT extensions passthrough on the EVE-NG guest machine configuration. The way you configure this really depends on the VMware ESXi version that you are running. As i am running VMware Server 5.1 the .vmx file was adjusted with the value:

Unifi controller on Synology NAS

This post is about how to configure and run the Ubiquiti unifi controller on a Synology NAS using Docker.

Quite recently I purchased UAP-AC-PRO access-point. Part of the Ubiquiti unifi solution is the unifi controller. I have tried installing the unifi controller on a Ubuntu 16.04 (LTS) system with shared applications but that didn’t work out well because of ipv6 running on this box. The installation of the unifi controller failed because of this. Normally you would dedicate a VPS to the unifi controller function. :)

Then i thought about running the unifi controller on my Synology NAS DS412+. After some investigation I saw that docker was an application that was available and that someone actually published the unifi controller on dockerhub.

Here’s some small steps on what you need to do to get the unifi controller running on a Synology NAS running DSM 6.0.2-8451 Update 6 using the GUI:

1.) Install docker from package center

2.) Open docker and go to Register, search for unifi “https://hub.docker.com/r/jacobalberty/unifi/” and click download.

3.) Within a few minutes (depending on your download speed) the image should be available in the image tab.

4.) Within the image tab click start and choose a wise name to identify your own unifi controller (mine is called wifi-controller).

5.) Set the network settings 1:1 (TCP/UDP ports), make sure you do not have any other applications running on these ports (like SabNZB).

6.) Start the wifi-controller and access it through: https://<nas-ip>:8443

Have fun!

Python script for PPPoE and PPPoA users

I wrote this python script to check for the amount of PPPoE and PPPoA users on a Cisco IOS-XE box. It’s also used by a provisioning system to check whether a PPPoX session came up or not. (Note: still learning Python)

The output will look like this for PPPoA users:

The output will look like this for PPPoE users:

Here is the script, latest version is always on github


Python script for PIM SSM mappings

A small functional python script to generate a lot of static SSM mappings for IOS-XR. The entries of mcast-groups.txt is an excel file (not comma separated).
