Friends, it finally happened. On August 7th, 2025, the number of spamtraps intended to woo the unwary spammer rolled past the number of inhabitants in my home country of Norway. It's time for a retrospective.

The updated #Gnome in #Debian 13 now supports importing #Wireguard .conf files directly and no longer requires you to do it manually in the terminal with nmcli. Just tested the "Import from file" option on a Wireguard config file and it worked perfectly fine,

#Homelab/#Networking question: I just realise that 'setting a static #IPv6 address' on a (#Linux) server is not as simple as it'd be with #IPv4 - one of the reasons being, realising, that the address prefix changes when my router restarts (i.e. due to any configuration changes).

When that network address prefix changes, obviously, any 'static' IPv6 address I'd like to set for my server would just be rendered invalid, since the network address portion/prefix is no longer applicable.

On my #TP-Link router, under IPv6 LAN settings, I saw an option to configure the Address Prefix - however, this field is currently prefilled with the network address prefix my servers/client devices are currently using/assigned to, and it is immutable (not configurable). To make it configurable, I could set a different setting on the same page called Prefix Delegation to Disable instead of its default, Enable.

My idea is to disable it, set an address prefix, and save/apply it - my expectation is, after the router restarts, all IPv6 addresses on my network will have that prefix, and it'll never change unless I explicitly do so (again, on the router). Is my idea right? or am I getting it tooootally wrong (which is possible bcos IPv6 is something else)?

With the imaginary friends, also known as spamtraps, now more numerous than the inhabitants of their virtual landlord's home country, a greytrapping retrospective is in order.

In this FreeBSD Journal article, Randall Stewart and Michael Tüxen walk through how SYN segments are processed during TCP’s three-way handshake—crucial for establishing reliable connections.

Learn how FreeBSD handles the client-server exchange and what happens behind the scenes during SYN, SYN-ACK, and ACK.

I want to share a fun blog post by @benjojo highlighting how there is still a vast amount of /24 private IPv4 addresses going unused.

There's also a fun generator at the end to create yourself a new never before seen range. (Or at least according to its 1.79 million devices that the dataset is based on).

Great work.

…yet all I see are dozens of different cable continuity testers in that range.

For actual networking functionality - verifying DHCP, addressing and ping etc they are in the hundreds to thousands of dollars price range.

I must be missing something… or should start selling a $50 tiny handheld box and cleanup?

Can you point me towards something?

#networking

Hey #networking #IT ppl, I'd often like a simple network tester - just plug in an RJ45 cable, and would tell me if there's live Ethernet, if DHCP is running, if an address was assigned.

Maybe for $5 more, an LCD to indicate what address I got, the gateway's address, maybe do a ping.

I've built *lots* of Arduino & RPi things that do netwk stuff, so I can alter one to be a tester - prob for $15 or less, but I thought – no surely there's a cheap, nicely pkg'd commercial one for $30…
