UPC/Magenta Fritzbox and IPv6 Prefix Delegation

I have started with the network migration today. There is now a fritzbox between the UPC ConnectBox and my router. For IPv4 this now means triple NAT \o/.

One of the most important task was to make my FreeBSD routers SSH port accessible from the internet.

What I have tried:

  • Wireguard: The FreeBSD go package uses SSE2 which results in an illegal hardware instruction. :-S
  • Reverse SSH: Yes it works. But I want something better.
  • IPv6: Following steps were necessary to get it working:
    • Disable the IPv6 Firewall on the ConnectBox
    • Enable IPv6 support on the Fritzbox
    • Disable “DHCPv6 Rapid Commit” on the Fritzbox.
    • Enable IA_PD and IA_NA on the LAN side of the Fritzbox
    • Configure my router as “Ipv6 Exposed Host” on the Fritzbox

Now what I have to think about: Do I trust the Fritzbox enough as a firewall?

Summer update

It is been 5 months since I last updated the blog.

So far no ECTS points for last term, due to some family problems. But the term started again, this time course on ottoman Palaeography.

Spent a great but expensive holiday in Greece.

Some payed traveling in September to Ireland, Croatia and Germany, year with the most flight miles since 2010. Due to some unfortunate events will be travel to Germany again next week.

While during summer I did lots of cycling to work. Unfortunately in September I got lazy again.

May Update

Noticed today that it has been 11 months since I returned to my current workplace. That means I have been back for longer than I had been away. Makes you think…

Apart from that busy in the hamster wheel. Some activities I should blog about elsewhere.

Just fixed a ‘502 Bad Gateway’ error on my blog. Seems to be php-fm isn’t as stable as expected. If this occurs again I will have to investigate further.

April Update

If you read this, I have switched my webserver from lighttpd, which I have been using for more than 8 years to caddy. Reasons: Built in Letsencrypt support. No longer dealing with spurious failures of the acme client. Config file looks really readable. Lets see how the memory footprint will develop. Also nar.arved.priv.at was updated to 10.4. There are still some maintaince tasks like switch from lighttpd’s spawncgi to php-fpm. But for now it seams I have working config.

March Update

Family off for family visit for two weeks. Unfortunately will not be able to make it through my long list of things to do. Work and university will take most of my time.
As the weather is quite bad, bought some swimming goggles, hope I will use them at least once.

This term at university I haven’t found a turkology course that I need and that doesn’t collide with other appointments. So this will be the last term for 18 EUR. Next term it will 380 EUR, so hopefully I will be able to study more serious to get more for my money.

Februrary Update

What happened:

Some changes in my network, I bought a Synology NAS, still trying to fill it up with various data on various machines. I bought a new Gigabit Switch, as the old one seems to be broken and I bought a new Accesspoint. The Ubiquity supports PoE which allows placement at a position where it covers the whole flat. Now I only need to get their management GUI unifi working on FreeBSD. Unfortunately my budget for Computer stuff is now finished, so no new Laptop until Summer 🙁

I am still struggling with my university assignments from last term. Next term it looks like none of the mandatory courses I need are offered, so I will probably take it easy.

Holiday plans have been made, looks like I will learn some Greek in summer.

The third incarnation of a BSD User Group in Vienna was launched. 2nd meeting is tomorrow, See BSD Stammtisch. Hope I will make it there.

End of the Year update

No November update, since I was busy with moving.

This month still busy with moving aftermath and of course christmas.

So lets see how I did with my Plans for 2017:

  • Continue studying (10+ ECTS) still doable
  • Work: Finish with AWS Competency and release NG firmware version 7.1done
  • More Sports: Motivate myself to run more than once every other monthfail
  • Hardware consolidation: Buy a new Screen.done Maybe a NASnot done or a new Desktop and retire direk.arved.priv.atnot done and sauna.arved.priv.atdone
  • Continue contributing to FreeBSD <50 commits, less than the year before and Wikipedia.143 edits, no new articles
  • Attend a conference, e.g. EuroBSDconfail

Sumam sumarum mixed results.

So My Plans for 2018:

  • Continue studying (10+ ECTS)
  • Finish EMV L2 Certification, do a cool, sucessful project
  • More Sports: Motivate myself to run more than once every other month. Get a bike.
  • Hardware consolidation: New NAS, New Desktop, retire direk.arved.priv.at
  • Continue contributing to FreeBSD and Wikipedia
  • Attend a conference
  • Read more books
  • Improve my foreign language skills
  • Travel

October Update

Put online my article from last terms university course: Fani.

Did a business trip to Basingstoke, UK. First year since 2010 than I have been traveling 7800km by plane.

Busy with getting ready to move. So not much time for anything else.

September update: Back from vacation

Spent two weeks on vacation in Turkey.

Finished two books, first El laberinto de los espίritus” by Carlos Ruiz Zafon, read in German (“Das Labyrinth der Lichter”). A present from my last birthday.

Second “Tour de France” by Irene Kuhn. My first book read in French (at least partially). The bilingual text worked fairly unlike when I tried bilingual Turkish-German books, where reading the original was way too tiresome.
But still there is lots of work to do to get my French back to the level I was 20 years ago.

Apart from swimming in the see I ran about 37km in two weeks. Now my right knee is still a bit stressed. Hope it is nothing serious.

Registered a private AWS accout to keep up with my cloud foo. Hope I will manage to stay in the Free Tier.

Registered for next terms course at the university, though I still haven’t got the result from last term.

In preparation for the move in October I decommissioned mchammer.arved.priv.at after 13 years of service. Most likely also sauna.arved.priv.at will be decommissioned in the next weeks.
