Link aggregation
Problem statement
#
The new switch supports 2,5 Gigabits, the computer connected to it has multiple
network ports all of which have only 1Gbit and we want more speed than a single
port offers, so we connect multiple ports to the switch.
Nomenclature
#
This is sometimes referred to as “Link aggregation” and also sometimes called
“Trunk Group Setting”, which is confusing because Cisco calls its 802.11q VLAN
tagging something with trunk as well (that is unrelated to link aggregation).

omg!ipv6
When I say I got ipv6 working I can imagine you may be asking how that is
special and you are right, theoretically at least. Practically I faced a
surprising amount of difficulties when I tried to configure my FreeBSD router
to get an ipv6 address from my internet service provider. Because of that I
configured my OpenVPN to route ipv6 traffic as an intermediate solution. That
however also took more time than I would have expected, because there is just
not enough documentation on the internet at this point in time and especially
when it comes to the question: How to route ipv6 from a jail over an epair
device. I mean… Try it, if you like, but I will soon publish an article about
that topic here and that could help you to save a lot of time. So either
believe me or proof to yourself, that you are more intelligent than me and that
you can do the same thing with ease. No problem, only that I refuse to add a
comment section to my website, so nobody will ever get to know, except…
Wait… You could very well post about your success on some social network.
Feel free to do so and do not forget to link my website. I like visitors, but
google does not like my site.

Released emocli
emocli is a little bash script, which
is able to display most of the emoticons and symbols found in Wikipedia
articles about Unicode and Charsets. The tool does not present an overview and
is not meant as a replacement for
gnome-characters, but better
suited to test the capabilities of different terminal emulators: The script can
add modifiers to the smilies and request a text-only representation by doing
so. Not all terminal emulators support that today. You can also use it to test
’new’ standards, e.g. the emoticons skin color tone after Fitzpatrick and
wonder how few emoticons are supported at this time.

Xfce/Thunar contribution
This is no
spectacular change, but it is really awesome how easy it is to contribute to
the Xfce project thanks to its maintainers like Alexander Schwinn. Thank you!
This really encourages further involvement.

apu4d4
I was looking for a way to use FreeBSD as router OS in my home. Its purpose was
to route OpenVPN traffic from and to my network, so that an individual host
configuration becomes unnecessary. My first setup was based on a raspberry
pi and that works good enough and is so simple, that it can easily be fixed
if something breaks.
I further improved the setup and installed a local DNS recursor in order to get
DNS under my control. That allowed me to name my devices relative to a local
domain, optimize the recursor cache to my needs and use DNS servers from the
opennic project for which I needed the cache
optimizations the most.

Raspberry infrared camera drill template
This camera is available online and gets seriously warm when turned on. Also it
is hard to mount in this form. Or short: A case is necessary and here is the
drill template for it (in SVG-Format)
And the result is good enough:

Smart home
I have never found it noteworthy that I have installed LED strips behind my
main monitors, because it used to be too dark there and was hurting my eyes.
For many years I had a crude LED-strip in a cable tie construction, not very
nice from a construction point of view, but as durable as such temporary
solutions always get. I have now upgraded the setup and for anybody interested
in how my desktop looks like today, here it is:
