Part2 – Monitoring Network Traffic with ntopng and nProbe

In the Part1 we have covered compilation of ntopng on Ubuntu 18.04.1 Server and installation of nProbe on Raspberry Pi 3. We have also configured Cisco Catalyst switch 3550 for traffic mirroring. The source of the traffic is the interface Fa0/3 where PC is connected and the destination port is Fa0/24 with connected Raspberry Pi 3B. This tutorial goes further and it covers configuration of the both ntopong and nProbe. First, let's have a look at the network topology.

Picture 1 - Network Topology

nProbe is running on Raspberry Pi 3B with the IP address 172.17.100.50/16. ntpong is running on Ubuntu 18.04.1 Server as the VirtualBox guest with the IP address 172.17.100.7/16. Our goal is to monitor network traffic from all devices connected to the ports of Cisco Catalyst switch 3550. In fact, we are monitoring only Windows 7 machine that is connected to Fa0/3.

Note: Without valid license, nProbe is working in demo mode and it is limited to show only 25000 flows export.

nProbe can work in two modes - poll mode and push mode. In a poll mode, ntopng dynamically subscribes to the probe via ZMQ, Continue reading

Campus design feature set-up : Part 3

We’ve said it before but since it’s important we’ll say it again. Shared knowledge makes for a stronger ecosystem! With this in mind, I’m showing you how to set up the CL 3.7.5 campus feature: Multi-Domain Authentication in a 6-part blog series.

In this series we’re covering it all: Wired MAC Authentication using Aruba ClearPass, Multi-Domain Authentication using Aruba ClearPass, Wired 802.1x using Cisco ISE, Wired MAC Authentication using Cisco ISE, and Multi-Domain Authentication using Cisco ISE.

This third guide is how to enable Multi-Domain Authentication in Cumulus Linux 3.7.5 + using Aruba ClearPass 6.7.x.

Keep in mind that this step-by-step guide assumes that you have already performed an initial setup of Aruba ClearPass and read the following Wired 802.1x using Aruba ClearPass and Wired MAC Authentication using Aruba ClearPass.

Over the past year, Cumulus Networks has made a concerted effort to expand the breadth and scope of the campus features within Cumulus Linux. Hot off the press in 3.7.5 is one of those features, Multi-Domain Authentication (MDA).

Classically, MDA allows for a voice VLAN and data VLAN to be configured independently on the same switch port for a VoIP Continue reading

Announcing Docker Enterprise 3.0: Delivering High-Velocity Application Innovation

Today at DockerCon, we’re excited to announce Docker Enterprise 3.0 – the only desktop-to-cloud enterprise container platform enabling organizations to build and share any application and securely run them anywhere – from hybrid cloud to the edge.

With Docker Enterprise 3.0, developers can rapidly build multi-service container-based applications right from their desktop and package them in a standardized format that can be shared seamlessly and run anywhere. In addition, Docker Enterprise 3.0 expands its container platform leadership position with the introduction of new capabilities for automated lifecycle management and enhanced security.

Here are some of the highlights that you can look forward to in Docker Enterprise 3.0.

Accelerated application delivery

Enterprises are looking for ways to quickly adapt to new competitive challenges and changing customer requirements through the introduction of new applications. Docker Enterprise 3.0 introduces a number of capabilities that help organizations accelerate application delivery.

Docker Desktop Enterprise

Docker Desktop Enterprise is a new developer tool that extends the Docker Enterprise Platform to developers’ desktops, improving developer productivity while accelerating time-to-market for new applications.

  • Application Designer interface: template-based workflows for creating containerized applications – no Docker CLI commands are required to get started
  • Configurable version packs: Continue reading

Dell, VMware Team Up To Tackle The Hybrid Cloud

As enterprises shift more of their workloads into public clouds and grow out their multicloud strategies – many are using three or more public clouds for their applications and data to as much  protect them against problems with the cloud provider as to take advantage of particular strengths that each cloud provider offer – there can be the tendency to think that many will end up putting everything in the cloud. …
