An alternative introduction to rspamd configuration: Modules (2/4)

May 22, 2018

Updated August, 24th, 2018

We already learned that the choice of modules basically determines which tests rspamd executes in analyzing a message. But what are the modules we can choose from? The official documentation has an alphabetical list but let’s instead approach them differently here. Continue Reading »

An alternative introduction to rspamd configuration: Introduction (1/4)

May 22, 2018

rspamd is a mighty spam filtering solution but it can be hard to get a grip on its configuration. For this reason I’m starting a small blog posts series to write down a few things I have learned, current for rspamd version 1.7.x. Continue Reading »

In 2018 the LOADays conference returns to Antwerp, Belgium on April 21st/22nd. LOADays stands for “Linux Open Admin Days” and is a small non-commercial conference targeted not only at the Belgian sysadmin/infrastructure scene, run by many of the fine folks that also brought you cfgmgmtcamp in Ghent. As with cfgmgmtcamp, instead of pissing off people with ever-increasing ticket prices, entrance is for free thanks to a number of sponsors. Continue Reading »

A sorted channels setup with a LG 42LB671V TV and a USALS motorized satellite dish

March 24, 2017

My LG 42LV671V TV is capable of receiving multiple satellites in a USALS motorized satellite setup. However, there are bugs and deficits in LG’s firmware and the correct order of steps to perform to get a proper channel list is not trivial.

Flashing a Huawei E3372h 4G LTE stick from Hilink to Stick mode

January 10, 2017

The Huawei E3372 is quite a popular LTE stick: it’s widely available (in retail stores, on eBay and also in branded variations, eg. “Telekom Speedstick V”, “Megafon M150-2”) and rather affordable (currently starting at €60 in Germany). It features a LTE Cat 4 modem supporting up to 150 MBit/s download and up to 50 MBit/s upload speeds, falls back to (DC-)HSPA(+), UMTS and EDGE, if necessary, and has quite small dimensions (88m x 28mm x 11.5mm).

Maintaining home network access from the outside with a network-controllable power plug, OpenWrt/LEDE and a 4G LTE stick

January 10, 2017

Internet routers are supposed to operate in a stable fashion. Except they don’t (FritzBox *cough*) – especially when you’re away from home and need access to your home resources.

Whoever designed Docker and containers clearly wasn’t responsible for InfoSec – a rant

May 12, 2016

Not just recently I’ve been trying to get a grasp of all the containerization hype and try to identify possible effects on the ways I see to do certain things. I’m reluctant to use the word “operations” here because I’m not really much of an “operations guy” in the sense of actually having ongoing responsibility for a significant number of machines, doing monitoring, getting woken up by a pager etc. I do however have enough administration experience on a small scale to be able to tell which ideas could work and which ideas clearly won’t, at least in the near time. I’m not going to draw the dividing line between “ops” and “devs” here once again, that topic has been bashed about enough for a long time. Continue Reading »
