Welcome to my new v3 onion

Gentoo recently marked Tor as stable on amd64 so without further ado I’m launching my v3 onion. This hidden service is available at the following 56 bit long address: 4hpfzoj3tgyp2w7sbe3gnmphqiqpxwwyijyvotamrvojl7pkra7z7byd.onion

DKIM fail – Invalid public key

So I had just implemented DomainKeys Identified Mail (DKIM) on a Postfix server and was confident that the signing process was correct, but on testing, the recipient’s SMTP server insisted that the message had failed authentication due to an invalid public key.

Validating HTTP requests using Apache's THE_REQUEST variable

I’m currently experimenting with a few rule conditions to explicitly whitelist the resources I want clients to be able to retrieve on my server. The initial target for this exercise was my onion site which has an issue with misbehaving (poorly written) Tor bots, but I thought it would be fun to extend the experiment to

Hakaied with love from Telecom Egypt

In the last two weeks I’ve seen a steady increase of bots trying to exploit a remote command execution flaw on D-Link routers. The majority of the attacks are originating from IP blocks belonging to Telecom Egypt Data.

What does the future hold for Slackware Linux?

Shortly following the distribution’s 25th year anniversary, Slackware maintainer Patrick Volkerding has shared some insight into his current financial situation and the issues he’s facing due to a lack of revenue from the Slackware store. According to Volkerding, the store has not forwarded any founds from sales or donations for the past two years.

GuixSD review - The herdless GNU

At the end of last year, I decided to install an interesting looking operating system named GuixSD. This was to be my first experience of running a system consisting entirely of free software. Unfortunately, the absence of non-free firmware also meant that I in 2018 would be giving up on wireless internet.

Python 3.6 default target reverted on Gentoo

After a long rebuild session yesterday due to the Python 3.6 upgrade, I was not overly impressed when issuing emerge --sync eventually resulted in a proposition to revert yesterdays work:

Python 3.6 is now the default target on Gentoo

Python 3.6 recently replaced Python 3.5 in the default Python targets on Gentoo systems. The change was announced a month ago, which provided more than enough time for me to forget all about it. Because of this, I was somewhat surprised today as Portage complained about unmet requirements for the fail2ban-0.9.6 ebuild.

Transitioning to Let's Encrypt wildcard certificates

A month ago I issued a wildcard certificate for * and patiently awaited the expiration of my old HPKP policy. Eventually the time to install the new key and certificate arrived, but to my great dismay, things did not turn out according to plan. Upon restarting the Apache web server, I got served with the following (epic) failure:

Zapping crashed services on Gentoo Linux

While configuring my first Gentoo VPS I somehow managed to crash a service and discovered that I had actually no idea how to recover it. The service no longer had any matching processes but it still refused to stop, and simultaneously insisted it was already started. Severely embarrassed I made sure nobody was looking and rebooted the server.
