I wanted to block #IP addresses based on some informations. So i started a small #Go #project to capture #packets. This quickly turned into more. I guess this becomes some kind of #XDR?

Clients capture packets, send these to the server, which stores them in a #database. This data is visualized on the dashboard. I'll also add controls to block ip's based on #regex, country and #abuseipdb score. This will be a fun project!

In today's thrilling episode of "This Will Definitely Work," we introduce #oniux, the latest #magic #trick promising to make #Linux apps play nicely with #Tor. 🎩✨ Because, of course, what every user craves is yet another layer of #complexity and hope that all those #packets don't wander off into the void. 🤞🔍

Anyone know how to get more information out of Minecraft than this? I'm trying to write my own server implementation and running into a metaphorical brick wall here.

Ok, went down a slight rabbit hole... You can use #nftables to log #packets to the nflog facility. #tcpdump or #tshark can read from the nflog queue and report info on the packets. Nftables can sample the packets randomly using numgen random mod 1000 < 50 I can sample 5% of packets (or whatever) if the output is easily readable by #Julialang I can turn the network visibility issue into a data analysis issue. What's the best way to read the output? tshark json?

The phishing attacker abused another API in the process: They collected the stolen passwords by misusing an API from the messaging service Telegram and sending the data to a bot account in a private channel. #Wireshark #packets #Telegram #spam #phishing #COpolitics

I just spent a number of hours troubleshooting a weird issue with my brand new Ubiquiti Aggregation switch. I haven’t figured out exactly what is going on yet, but the problem is weird enough I wanted to toss it out and see what the Fediverse thinks.

I have two 10gbe hosts. FreeBSD Samba server and Linux client. Both plugged directly into the Aggregation switch (via SFP+ RJ45 adaptors).

Client can mount share, but ls fails. Any I/O on the volume hangs for tens of seconds before failing.

Prior to installing the USW-Aggregation, these same two hosts were connected together via a MikroTik 10gbps switch, and everything was working fine. (You may ask why I decided to replace a perfectly good MikroTik switch with an Ubiquiti product, and honestly now I am wondering the same thing.)

After lots and lots of experiments, it becomes clear that simply routing the traffic over the Aggregation switch is enough to cause the connection to fail.

Diving into the tcpdump on the client side, I find the client sending the same TCP packet over and over, retransmitting with an apparent exponential backoff until it times out and fails with an error.

On the server side, tcpdump shows the packet being received and the reply being sent instantaneously. However, the reply never makes it to the client.

The USW-Aggregation, in its default configuration, is completely swallowing this packet.

I dig around in the settings and turn on Jumbo frames and Flow Control. The problem magically goes away!

Fediverse, what is going on here?

Episode 3 of Packet Tuesday is live. This week, it is all about the TCP Urgent flag. Trying to keep them a bit shorter in the future to not spent half an hour on one bit ;-) https://packettuesday.com

I hope everybody is enjoying these as much as I do. Thinking about moving on to some SSL stuff next, but also trying to keep them a bit shorter. Let me know if these work for you, or what I can improve. If I spent half an hour on a TCP flag… who knows how long the SSL Client Hello episode will get :)

And please let me know if I am making mistakes. I am not perfect and actually learn new things as I put these together. Well, I can always claim that I add intentional mistakes to increase “engagement.” :)

Our world is connected.

We see evidence of that from seeing social media updates from people around the world or news broadcasts that cover events happening from anywhere. But have you considered the physical infrastructure of the internet? Of course there are datacenters, giant buildings with loud computers buzzing away. But those buildings need to be connected to each other, to your modem at home, to mobile cell towers that are sprinkled all over the place, and "to the internet". But what does that mean? Contrary to popular belief, satellites are NOT how most information travels the world. Indeed, we have physical cables all over... but instead of carrying electrical signals those cables carry light generated by lasers.

These cables not only exist alongside roads and hung on power lines. They're also running along the bottom of the world's oceans. The image below is an inventory of each of these underwater internet cables. What I find interesting is how many there are! It seems like a lot. But then when I think more about it I am also amazed at how few there are. If you pay attention you will see news articles describing occasional sabotage of these cables, here's one recently published by Wired: https://www.wired.com/story/submarine-internet-cables-egypt/. This is actually very important to the future and security of the global internet.
