H3/H2 Net Card – ODROID – wonder how well pfSense supports it

Posted by jpluimers on 2025/04/18

I wonder how well [Wayback/Archive] H3/H2 Net Card – ODROID is supported by pfSense. It is an M.2 based PCIe network card that adds 4 ethernet ports of 2.5 gigabit each to an ODROID H2 or H3 series (so you have 6 ports total), ideal for some hefty router.

Pictures (from the above link) of the board, cases and mainboard below.

But first: Realtek NICs is not vendor supported on FreeBSD (which pfSense and OPNsense are based on).

How to send raw network packets in Python with tun/tap

Posted by jpluimers on 2025/02/20

For my link archive: [Wayback/Archive] How to send raw network packets in Python with tun/tap

I never really played around with tun and tap, so this is a nice opportunity to do so. I know they were the base for VPN on Linux, but just now I learned TUN/TAP are not available on nx, but also on Windows. Cool!

Latest Products/Feature Request Board topics – Ring Community

Posted by jpluimers on 2025/01/03

Yup, I have been in the Ring ecosystem since way before Amazon took them over, and it is kind of hard to part from the useful cameras, so here is for my link archive: [Wayback/Archive] Latest Products/Feature Request Board topics – Ring Community

IPv4 subnet/CIDR table from OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation …”

Posted by jpluimers on 2024/11/27

I wrote about programs and scripts doing IPv4 subnet calculation, but sometimes it is easier to have a table at hand, so here is the one I found at [Wayback/Archive] OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation #networks #networkbasics #subnetting #infosec #networks4hackers #cyberwarrior #cyberwarrior #networkbasics #networkbasics subnet”

I’m not the only one storing tech gadgets in flight cases (:

Posted by jpluimers on 2024/09/05

It was about 2 years ago that Jilles reminded me I had a flight case with gadgets too.

Back when I assembled it in 2018, I had big plans for showing private “cloud” container experimentation and gadget stuff at conferences. Then 2019 kicked in with rectum cancer.

So it was good that he helped me motivating to get it working again, especially as the time around assembling it so much fun and working on it brought back those days.

Here are the pictures:

It looks like Fritz!Box rebinding protection also prevents accessing a FritzBox over a SSH port forwarding

Posted by jpluimers on 2024/08/09

For quite some times my back-up way to access a Fritz!Box when the VPN itself failed was to SSH into a system behind it and use SSH port forwarding to access the Fritz!Box.

Seems that only works for older models with older firmware versions, but newer models with newer firmware now give a rebinding protection error.

I am not sure why it does this as technically there is no [Wayback/Archive] DNS rebinding – Wikipedia.

Regrettably, I could not find a way around this from the links below.

This is how I found out.
