    Photons are the smallest unit of energy that can be transferred between a light wave and a different particle.

    That is a much better description than what I have heard for the last 30 years: “A photon is a packet of energy”. That made no sense to me back then, and makes no sense to me now and, IMHO, doesn’t quite give a good visualization. It’s a placeholder, and I suppose it is slightly accurate depending on how “packet” is defined.

    That’ll break a few brains. To elaborate with an example: From the perspective of a photon, it’s “life” is over as soon as it begins. Even though it takes about 8 mins for a photon to travel from the sun to the earth from our perspective, no time at all has passed for it.

    (Correct me if I misspoke.)







  • Of course I do, but its very conditional in your case. For the record, I did miss that you had port forwarding enabled already and read your post as if you were just trying to connect to the open internet and see any traffic going to some rando servers. That would be a very different situation.

    How is the traffic proxied locally? Does the VPN client even allow inbound connections? Is a virtual interface configured for the VPN and is there an inbound port open?

    What makes this situation conditional is that there are several ways your VPN client could be configured and it is my guess that it is the bottleneck in this case. If you tried every address that you could find and saw nothing, chances are, there is no traffic to be seen. Any stateful firewall will drop an inbound SYN or traffic not related to an established connection.

    Your routing table may give some good clues as to where traffic is going as well. For example, the VPN client could be creating a local default gateway IP. Unless there is a split path configured, all traffic should be traversing that IP, regardless of what it is.

    So, can you elaborate more on the route your traffic is taking? Listening on 0.0.0.0 can sometimes work, but usually a specific interface needs to be defined as well. In some cases, tcpdump setting the interface to promiscuous mode can break things.

    Also, it’s a VPN. How traffic is getting routed in through the tunnel could be problematic. I have just been assuming that everything is fine up to the client you use and the computer sending traffic to inside your network is part of the VPN.


  • Ok, you are putting the cart a few steps before the horse here and put simply, you can’t just tap the entire Internet from behind your own Internet connection and “through” a VPN. (A VPN “tunnel” is a bit misleading on how traffic is seen in the wire, but that is still many more steps ahead.)

    Watching pcap is cool, but you need a fundamental understanding of networks and network protocols before you can actually see more than characters of the Matrix and understand what you are tapping into from the start.

    To kick off your own research path, start reading into the OSI Model, TCP vs UDP, traffic routing and subnetting. You need to understand where you need to be to see the traffic you want to see first.

    Unfortunately, I can’t begin to answer your question without some foundation in place first.







  • Yes, I know the point is that the president said the troops were unarmed. However, I just want to deflate the shock factor of 57,000 rounds.

    57,000 rounds could be a lot of it could be a little. If the 1st Special Forces Brigade has about 1000 members with probably only 800 or so preparing for a bad scenario, that is about 65-100 rounds per soldier. That is just… standard.

    It’s also expected that military forces are going to use multiple weapon types and each one of those needs a usable amount of ammunition. It just inflates the numbers much more.

    I just wanted to put scale around what is probably just a minimum amount of ammunition. What is interesting is how much more stuff is needed to support troops like that. You need food, water, gear, medical supplies, etc… and my point is that military logistics is crazy, even with small deployments.


  • It depends not only on what you want to control, but also how you want to control it.

    I’ll use a fader/slider for when I am recording MIDI and need to return the fader back to very specific spot quickly, or, if I want to “play” something like the cutoff freq on a filter. I can just smack the slider back and forth quickly like I am strumming a guitar.

    I’ll usually map knobs when I need very fine controls. If you don’t need to min/max whatever setting you are working with, you put the knob about where it should be and only work a few degrees of rotation. (Rapidly min/max’ing a knob sucks since we typically do not rotate our wrist to mix/max quickly.)
