Making LLDP Work with Linux Bridge

Last week I described how I configured PVLAN on a Linux bridge. After checking the desired partial connectivity with ios_ping I wanted to verify it with LLDP neighbors. Ansible ios_facts module collects LLDP neighbor information, and it should be really easy using those facts to check whether port isolation works as expected.

Ansible playbook displaying LLDP neighbors on selected interface
---
- name: Display LLDP neighbors on selected interface
  hosts: all
  gather_facts: true
  vars:
    target_interface: GigabitEthernet0/1
  tasks:
  - name: Display neighbors gathered with ios_facts
    debug:
      var: ansible_net_neighbors[target_interface]

Alas, none of the routers saw any neighbors on the target interface.

SolarWinds Trojan: Affected enterprises must use hot patches, isolate compromised gear

Hot patching and isolating potentially affected resources are on the IT response schedule as enterprises that employ SolarWinds Orion network-monitoring software look to limit the impact of the serious Trojan unleashed on the platform.The supply-chain attack, reported early this week by Reuters and detailed by security researchers at FireEye and Microsoft involves a potential state-sponsored, sophisticated actor gained access to a wide variety of government, public and private networks via Trojanized updates to SolarWind’s Orion network monitoring and management software. This campaign may have begun as early as spring 2020 and is ongoing, according to FireEye and others.To read this article in full, please click here

Supercharge CoreDNS with Cluster Addons

Infoblox sponsored this post. Sandeep Rajan Sandeep is a software engineer at Infoblox focussing on open source contributions to the Cloud Native Computing Foundation (CNCF) projects CoreDNS and Kubernetes. There has been an increasing demand from users to be able to manage the health, status, rollout, rollback, etc., of CoreDNS in a Kubernetes cluster; and not just rely on CoreDNS being managed by the cluster management tools. Since the use of Operators in Kubernetes is now generally accepted, the aim of the

The History of EARN, RARE, and European Networks (part 2)

European networks from the mid-1980’s to the late 2000’s underwent a lot of change, bolstered by the rise and fall of America Online, the laying of a lot of subsea cables, and the creation of several organizations, including EARN and RARE, to bolster the spread and use of the Internet. Daniele Bovio joins Donald Sharp and Russ White on this episode of the History of Networking to give us a good overall perspective of this history.

Trojan in SolarWinds security has far-reaching impact

SolarWinds says a compromise of its widely used Orion network-monitoring platform endangers the networks of public and private organizations that use it and that the problem should be remediated right away.In a security advisory, SolarWinds said customers should upgrade to Orion Platform version 2020.2.1 HF 1 as soon as possible to ensure their environment is safe. An additional hotfix release that both replaces the compromised component and provides several additional security enhancements is expected in the next day or two.The company’s managed services tools appear to be uncompromised, and the company said it isn’t aware of any similar issues with its non-Orion products, like RMM, N-Central, and SolarWinds MSP products.To read this article in full, please click here

Full Stack Journey 049: Kubernetes Backup And Data Protection With Open-Source Velero

Have you developed a backup/restore strategy for your Kubernetes clusters? In this Full Stack Journey episode, we discuss why Kubernetes operators should be planning for backup/restore functionality, and debunk some myths that say you don't need it in Kubernetes. We also dive into the open-source Velero project, a tool for backup/restore and data protection of Kubernetes cluster resources. Our guests are Carlisia Thompson and Nolan Brubaker.
