Tiens depuis ce matin j'ai un comportement spécial sur le TorBrowser, après avoir ouvert plusieurs onglets en succession rapide : y'en a aucun qui se charge, et l'onglet "réseau" de l'inspecteur me dit "aucune requête" quand je tente de recharger une page ou d'en ouvrir un autre...

In this demo, see how to use Visual Studio Code, GitHub Copilot, and the Puppet MCP Server to generate an EdgeOps automation task for your network devices!

This video shows you how to setup your mcp.json file and then prompt for a task that configures NTP servers on a switch using your device's configuration info.

My router interface traffic graphs are pretty useless. Every night around 2:00am, various things run backups. Some do backups across the network, others copy out to an off-site location. But the bottom line is that if I look at my network interface graphs, that massive spike every night ruins the Y axis.

These are the daily, weekly, and monthly graphs. And the fact that daily hits around 450M, but ordinary hours are like 8-10M, it means I can't see the rest of the graph. It means that I can't spot changes or interesting things.

I'm not really sure how to do better. (It's amateur hour over here)

A daily graph with hours on the X axis and Mb per second on the Y axis. In and out are blue and green, but they're basically indistinguishable from the X axis line. From 2:00 to almost 4:00 there's a huge spike up to 450 Mb per second.

A weekly graph with days of the week on the X axis and Mb per second on the Y axis. In and out are blue and green, but they're basically indistinguishable from the X axis line. Each day there's this sharp green spike up to 450 Mb per second.

A monthly graph with weeks on the X axis and Mb per second on the Y axis. In and out are blue and green, but they're basically indistinguishable from the X axis line. There are 5 sharp spikes up to 450 Mb per second in each week.

We’ve published new research from the EU co-funded project NGSOTI: “Learning from large-scale IPv4 blackhole: Behavioral analysis of SNMP traffic”.

Over a 12-month period (Nov 2024–Oct 2025), our network telescope captured ~634 million unsolicited SNMP queries from more than 153,000 unique IPv4 sources scanning an unused /18 block.

The origins of the traffic are globally distributed, with notable concentrations from Indonesia, China, the United States, Germany, Chile and others, as well as a few outliers generating unusually high volumes. A significant portion of the scanning activity can also be attributed to infrastructure belonging to commercial threat-intelligence and scanning companies, providing useful context on what constitutes “expected” background noise.

The analysis covers SNMP version usage (v1/v2c overwhelmingly dominant, minimal v3), community-string patterns (default, weak, and undocumented strings), and OIDs that point to which device vendors are most scanned.

This dataset provides insight into real-world reconnaissance trends targeting SNMP-capable infrastructure, helping defenders better understand background noise and scanning behaviours.

I'm @shalien , a computer enthusiast as #dev as #network .

Disappointed with Twitter / X , I resurrected my #mastodon instance and here I am.

I hope to discover something else, something healthier and more relaxing than the permanent chaos of Twitter.

Looking forward to seeing you in the #Fediverse!

Is anyone else finding that their network connections are VERY slow this week? I'm trying to decide whether the slowness and browser timeouts are still the aftermath of the big outage (so likely to improve) or an effect of my awful internet connection (so I need to yell at someone at my ISP.

DNS is probably involved, since the worst problems seem to happen when I try to follow links to servers I'm not currently accessing.

Does anyone have root DNS servers they favor?

Cache of Devices Capable of Crashing Cell #Network Is Found Near #UN

The #SecretService discovered more than 100,000 SIM cards & 300 servers, which could disable #cellular towers or be used to conduct #surveillance.

The #SecretService found & seized an illicit #network of sophisticated equipment in the New York region that was capable of shutting down the #cellular network as foreign leaders prepared to gather nearby for the annual #UNGA, the agency announced on Tuesday.

Officials said the anonymous communications network, which included >100k SIM cards & 300 servers, could interfere with #emergency response services & could be used to conduct encrypted #communication.

#GlobalSecurity #NationalSecurity

One official said the network was capable of sending 30 million text messages per minute, anonymously. The official said the agency had never before seen such an extensive operation.

There is no specific information that the #network, now dismantled, posed a threat to the conference itself, #SecretService officials said, speaking on the condition of anonymity to discuss an ongoing investigation. The agency leads the #security for the #UN meetings this week.
