Node-RED

Posted by jpluimers on 2019/12/11

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.

Seems one of the ways to automate our home: [WayBack] Node-RED, as it supports many input and output methods with all kinds of nodes between them:

input output
inject debug
catch
status
link link
mqtt mqtt
http http response
websocket websocket
tcp tcp
udp udp
serial serial

It is based on node.js, seems to need PM2 for running as a service, so I need to first figure out how well it runs on OpenSuSE (with more details than this gist).

After that I need to figure out how to version your configurations using git and document as it looks like the configurations sources are stored in JSON format [WayBack].

For resources:

  • StackOverflow node-red tag
  • Github node-red repositories
  • nodered documentation to:
    • get started (including Installation, Running, Adding non-stock Nodes, Upgrading, Creating your first and second flow, running on Docker / Windows)
      • running on a device (Raspberry Pi, BeagleBone Black, Android) which needs extra device specific modules to hardware inputs/outputs
      • communicating with a device (Arduino)
      • running in the cloud (IBM Bluemix, SenseTecnic FRED, Amazon Web Services, Microsoft Azure)
    • user guide (including Configuration, Security, Logging, Command-line Admin, Writing Functions, Embedding into an existing app)
    • cookbook (with many flows covering Basics, HTTP and MQTT)
    • creating nodes (with a wall of information: Creating your first node, JavaScript File, HTML File, Storing Context, Node properties, Node credentials, Node appearance, Node status, Configuration nodes, Help style guide, Packaging, Internationalisation)
    • flows (hundreds of them)

Code is published as JSON, but I wish more examples also showed the visual representation.

Forticlient “the user might login in another computer”, never found the cause

Posted by jpluimers on 2019/11/25

Could only find one reference using “the user might login in another computer” – Google Search, who also could not find out why this error happened:

When trying to log in on FortiClient, I get an error message that says, “the user might login in another computer” I assume that could mean that I’m logged in on another machine elsewhere? I could not find any information confirming that.

[WayBack] Error Message | Fortinet Technical Discussion Forums

So I reached out to Fortinet, the makers of Forticlient:

[WayBack] Jeroen Pluimers on Twitter: “@Fortinet what could cause this? Searching for the message “The user might login in another computer” did not get me any further: https://t.co/Bl4KoWJ7IB FortiClient 6.6.1.723 on MacOS High Sierra.…”

For my link archive: IPVoid.com

Posted by jpluimers on 2019/11/25

Nice landing page to check various aspects of IP addresses: [WayBack] ipvoid.com:

We offer a vast range of IP address tools to discover details about IP addresses. IP smtp blacklist check, whois lookup, dns lookup, ping, and more!

I irregularly use them to check out blacklist issues (yes, sometimes 8.8.8.8, 8.8.4.4 and even 9.9.9.9 appear on blacklists).

Netgate SG-3100 is an ARM based pfSense Firewall Appliance

Posted by jpluimers on 2019/11/04

By now I should have had plenty of time to try out an ARM based pfSense multi-WAN router like the [WayBack]  Netgate SG-3100 is an ARM based pfSense Firewall Appliance.

So this is a reminder for myself to write down more detailed experiences than the summary at [WayBack]Netgate SG-3100 pfSense Security Gateway Appliance.

It is in the Mikrotik price range, but each time I use those I bump into mysterious RouterOS issues that only I seem to have.

Dean Bubley’s Disruptive Wireless: Debunking the Network QoS myth

Posted by jpluimers on 2019/08/09

QoS doesn’t work, except for one specific scenario:

Where QoS works is where one organisation controls both ends of a connection AND also tightly-defines and controls the applications:

  • A fixed-broadband provider can protect IP telephony & IPTV on home broadband between central office & the home gateway.An enterprise can build a private network & prioritise its most important application(s), plus maybe a connection to a public cloud or UCaaS service.
  • Mobile operators can tune a 4G network to prioritise VoLTE.
  • Telco core and transport networks can apply differential QoS to particular wholesale customers, or to their own various retail requirements (eg enterprise users’ data vs. low-end consumers, or cell-site timing signals and backhaul vs. user data).
  • Industrial process & control systems use a variety of special realtime connection protocols and networks. Vendors of “OT” (operational technology) tend to view IT/telecoms and TCP/IP as quaint. The IT/OT boundary is the real “edge”.

This is not news, but it’s worthwhile repeating: it is actually cheaper to build a network that can carry the traffic than building a network that keeps quality promises on a backbone that is undersized or close to capacity. Overprovisioning works, everything else does not, economically as well as technically.

RP-SMA dummy loads for nonadjustable WiFi devices and Adjust Fritz!Box WiFi power – via Knowledge Base | AVM International

Posted by jpluimers on 2019/07/19

Via [WayBack] Knowledge Base | AVM International:

3 Setting the maximum transmitter power

  1. Click “Wireless” (“WLAN”) in the FRITZ!Box user interface.
  2. Click “Radio Channel” in the “Wireless” (“WLAN”) menu.
  3. If the option “Set radio channel settings automatically (recommended)” is enabled, proceed with the following section.
    • If the option “Adjust radio channel settings” is enabled:
      1. Click “Additional settings”.
      2. Select “100%” from the drop-down list “Maximum transmitter power”.
      3. Click “Apply” to save the settings.
For me, having minimal power was important since every now I needed to be able to connect to it, but only when I was in close proximity.

Hence the settings below: 6% Maximum transmit power is the lowest I could set.

For devices that cannot adjust their antenna output power which have RP-SMA connectors, I bought these to effectively throttle them:
