jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

Posted by jpluimers on 2017/12/31

This is what DevOps is all about: [WayBack] jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”

I had seen the tweet before, but forgot to save it. Jonas Bandi reminded me of it at [WayBack] Weekend Reader: End of Year Edition – reality-loop.

Jessie is doing great work. For instance, she developed and published contained.af, and nobody captured the flag yet: [WayBack] jessie frazelle on Twitter: «A year ago I made contained.af and it’s launched over 128,000 containers & no one has retrieved the flag».

The game runs in a container, gives you console access and has a bunch of questions. Still need to dig deeper in it, as it is a fascinating set-up. If you like to try it:

Wishing you a year where nobody captures your flags (:

iptables debugging « \1

Posted by jpluimers on 2017/11/28

Using the TRACE target: [WayBack] iptables debugging « \1 via [WayBack] iptables Debugging using the TRACE chain – Kristian Köhntopp – Google+

Docs:

TRACE
This target marks packes so that the kernel will log every rule which match the packets as those traverse the tables, chains,
rules. (The ipt_LOG or ip6t_LOG module is required for the logging.) The packets are logged with the string prefix: “TRACE:
tablename:chainname:type:rulenum ” where type can be “rule” for plain rule, “return” for implicit rule at the end of a user
defined chain and “policy” for the policy of the built in chains.
It can only be used in the raw table.

Way more details in the linked article.

New steps for Slack on Twitter: “@thorduri 😣 You can always disable emoji conversion in Preferences > Emoji > Convert my typed emoticons to emoji. 👍”

After: @thorduri You can always disable emoji conversion in Preferences > Emoji > Convert my typed emoticons to emoji. [WayBack]

We live in the form-over-function era [WayBack], so of course this setting is not reachable by URL, only reachable by using these steps:

It’s such an all time classic from 2006 that people even kept scans of the original 2006 Computer World publication by [WayBack] John Klossner.

Over the last few years, it has done its round over the internet a few times, so I did some digging for the scans, colour and mono originals.

Data security versus Human Error.

In this corner, we have firewalls, encryption, antivirus software, etc. And in this corner, we have Dave!!

[WayBack] John Klossner Cartoons: Computer World has the original black and white version: it’s even a gif!

Way better than the scan from paper: [WayBack] ShackF00 » Weekend Round-up: Google Issues and a Sad-but-True Comic

In 2014, Spiceworks re-ran the black and white one: [WayBack] And in THIS corner we have Dave! (Funny cartoon) – IT Security – Spiceworks

In 2015, Wombat Security published a coloured version on social media, and even bigger too: not just large, huge as well (:

How to turn on your lights the Philips way

Posted by jpluimers on 2017/06/23

This was too funny to let go unnoticed: [WayBack] How to turn on the light at home, Philips Version – Kristian Köhntopp – Google+.

It was shown during [Archive.is] Google Cloud Next 2017 in Amsterdam and immediately reminded me of The Big Bang Theory – How to turn on a lamp below.

A few notable entries from the comments:

  • Wie viele Server braucht man bei Philips, um eine Glühbirne zu wechseln?
  • Apple macht das wohl ähnlich, hier dient ein AppleTV oder ein iPad als “Bridge zur Bridge”.
  • They’re at least honest — the icon of the cloud in the upper left prominently displays a “waiting” circle animation. I also notice the use of the word “looks” rather than “works” in the title, which is probably also accurate.

Google DNS, Open DNS or your ISP DNS servers?

Posted by jpluimers on 2017/05/26

There are various arguments for using Google DNS (8.8.8.8 or 8.8.4.4) or Open DNS servers or not. A few are listed here:

It basically comes down to two things:

  1. DNS speed
  2. CDN speed (Contend Delivery Network providers like CloudFlare, Akamai, etc)

If your DNS server isn’t close to you, it might select a CDN server that is far from you. If you rely on CDN, then you need to weight in that factor.

This is how I decide:

  • devices not needing CDN: use Google DNS or Open DNS
  • devices needing CDN: use Namebench to pick fast DNS servers that are nearby based on Namebench reports with “Recommended configuration (fastest + nearest)”

Amazon 2FA Account Recovery HOWTO I had enabled 2FA on my amazon.de account,…

Posted by jpluimers on 2016/11/25

[WayBack] Amazon 2FA Account Recovery HOWTO I had enabled 2FA on my amazon.de account,… – Kristian Köhntopp – Google+

Quoted in full as it is too important to forget where I put this:

Amazon 2FA Account Recovery HOWTO

I had enabled 2FA on my amazon.de account, and the device running the only copy of the TOTP seed has been destroyed. I wanted to disable 2FA on my account in order to be able to access the account until a replacement phone was available.

To enable 2FA on an amazon.de account, you have to login to amazon.com using your amazon.de credentials and then go through the 2FA procedure.

Calling the german hotline for help did not work. They did not know about 2FA disablement and were unable to help me. They did know about 2FA in general, have been able to verify and validate my identity and were generally friendly. They have been calling me back repeatedly.

I later remembered how I enabled the 2FA and did try to login to amazon.com, giving my german credentials and ended up on the “Enter 2FA code” screen. There is a link at the bottom, “Did not receive code”.

Clicking that link takes you to a screen where you can choose between Google Authenticator and SMS identification.

I chose SMS auth, did receive a 6 digit code, entered that and was able to auth. I then was able to temporarily disable 2FA and regain control of my US account. This also disabled 2FA for my german account, and I now have my German account back.
