Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.b…

[WayBack] Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte. EDIT: Muahahaha … – Kristian Köhntopp – Google+

Now there is http://nic.box/ for the new [WayBack] box top level domain and AVM does not yet have the pre-registered fritz.box there effectuated (because .box is not in final registration state yet).

Kristian:

Schlechte Nachrichten für Fritz!box User: http://nic.box/ Euer http://fritz.box ist nicht mehr das, was es sein sollte.

EDIT: Muahahaha

kris@h1755802:~> host fritz.box
fritz.box has address 127.0.53.53
fritz.box mail is handled by 10 your-dns-needs-immediate-attention.box.

The joke is in the cryptic “your-dns-needs-immediate-attention” and usage of 127.0.53.53. to indicate a gTLD name collision.

Chrome knows about ICANN though and explains it in a slightly more readable form when browsing to http://fritz.box (:

Inspecting/unpacking a Linux rpm file on Mac OS X

Posted by jpluimers on 2016/11/18

You need this statement to unpack an rpm file on Mac OS X without having rpm installed:

rpm2cpio ##filename.rpm## | cpio -idmv

This will make rpm2cpio unpack the rpm file in the current directory using these cpio options:

  • i – use the rpm2cpoio as unput
  • d – created directories when needed
  • m – set modification timestamps from the archive
  • v – verbose filenames to stderr

cpio is already part of the Mac OS X system.

You can get rpm2cpio through homebrew by typing brew install rpm2cpio which will likely also download he xz dependency.

Why I always disable Castalia in Delphi

I wrote about disabling Castalia before. This is yet another reason why I disabled it: on a fresh install it will throw errors at startup like this one in XE8: [WayBack] http://qc.embarcadero.com/wc/qcmain.aspx?d=139278

If you are a KDE neon user, reinstall your distro now! | CIO

Posted by jpluimers on 2016/11/18

Security always has the human factor involved which means that we screw up like here:

Source: [WayBack] If you are a KDE neon user, reinstall your distro now! | CIO

A little blunder was committed by the core developers that made the entire archive insecure:

“Best practice when setting that up is to use the trusted SSH protocol to open a tunnel and upload through that,” said Riddell, “Unfortunately in setting up that new archive I had it listening for uploads on the whole network not just the local SSH tunnel.”

Getting the vendor from an ethernet network MAC address on-line through the Wireshark OUI Lookup Tool.

Posted by jpluimers on 2016/11/18

In networks, often you want to know which manufacturer or vendor is behind a MAC address.

An easy way to look this up on-line is by using the
Wireshark · OUI Lookup Tool which should have had MAC or MAC address in the title.

It uses both the extensive /etc/manuf Wireshark Ethernet vendor codes and well-known MAC address prefixes (which is a long text file generated from several sources). Some of the prefixes are just the 24-bit (6-hex digit) OUIs, but others are much more fine grained.

What’s really cool is that the tool accepts a very lenient formatting of inputs: full, partial, various hex separators (including none), case insensitive, and vendor names/abbreviations. So entries like these magically work.

Versioning common sense (major.minor.patch) has a name: Semantic Versioning 2.0.0

Posted by jpluimers on 2016/11/17

I just discovered the versioning common sense I’ve used for decades actually has a name. It’s even a “standard”!

Semantic Versioning 2.0.0 Summary

Given a version number MAJOR.MINOR.PATCH, increment the:

  1. MAJOR version when you make incompatible API changes,
  2. MINOR version when you add functionality in a backwards-compatible manner, and
  3. PATCH version when you make backwards-compatible bug fixes.

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

I discovered it via:

tmux attach to named session or create when it doesn’t exist yet – via: How to start tmux with attach if a session exists – Unix & Linux Stack Exchange

Posted by jpluimers on 2016/11/16

In my alias list:

alias "tmux-attach-or-create-main-session=tmux new-session -A -s main"

Via User Wesley Baugh – Unix & Linux Stack Exchange who answered:

If naming your session is okay, then it’s easy to do with the new-session command:

tmux new-session -A -s main

where main is the session name that will be attached to or created if needed.

From man tmux

 The -A flag makes new-session behave like attach-session if session-name already exists; in this case, -D behaves like -d to attach-session.

`xcode-select –install` required for OS X 10.9 Xcode command-line tools (like `zlib-devel`)

Posted by jpluimers on 2016/11/16

Hopefully this was a one time oversight from Apple, but on OS X 10.9 (Mavericks) the Xcode command-line tools cannot be installed from the Xcode Preferences pane.

You have to install them from the command-line:

xcode-select --install

There is one catch though: it might fail as you first have to start Xcode once and accept the license agreement.

You need them for instance when playing with zlib-devel (for instance when creating your own openssl builds).
