Out of the box, a MacBook can do tethering using:
I’ll point to two things about this below:

OSvirtual is a collection of virtual images of operating systems.
It’s a resource for those who want to recall some operating system/distribution, to try unknown OS or just to play with the virtual toy :)

The dig (domain information groper) command under unix/Linux is a great way to help verify that a DNS host like BIND is working properly.
A few of my servers are Linux, but most of my desktops usually are Windows, so I was happy to find the Using the dig dns tool on Windows 7 article by Dan Esparza explaining there is a Windows version.
So I:
dig @192.168.171.214 pluimers.com

Great! And it is open source at https://github.com/google/nogotofail:
The Android Security Team has built a tool, called nogotofail, that provides an easy way to confirm that the devices or applications you are using are safe against known TLS/SSL vulnerabilities and misconfigurations. Nogotofail works for Android, iOS, Linux, Windows, Chrome OS, OSX, in fact any device you use to connect to the Internet.
There’s an easy-to-use client to configure the settings and get notifications on Android and Linux, as well as the attack engine itself which can be deployed as a router, VPN server, or proxy.

I just learned (thanks Chris Wahl!) about the dcui command: often easier to configure basic parameters than the other UIs.
The DCUI is normally available from the console after you login, for instance to enable SSH.
This was new to me:
DCUI is available over SSH.
Even more embarrassing: duic has been actually there since ESXi 4.1 (:

Be sure to read the comments at Chris Mason deklariert BTRFS als Stable, und Suse setzt es als Default für / in der neuen SLES ein….
Some of the comments provide great insight in the practical use of:

Had to download a bunch of stuff over the command-line from an IIS server that was using authentication. Not basic authentication, but NTLM authentication.
wget kept failing, even wget 1.10 that usually does NTLM quite OK (but up to 1.10.2 has a security vulnerability so you should not use wget 1.10 any more).
So I installed a Windows x86 cURL binary, and downloaded+copied the root certificates, then did some reading on the command-line switches.
Without any, cURL does http basic authentication. But a Windows server usually expects NTLM authentication (hardly documented, but it uses the Negotiate protocol).
When not using NTLM, both would show (wget -d, or curl -v) this in the output, indicating you should use NTLM authentication: Read the rest of this entry »

Thanks to the wonderful people at the opensuse forums (especially Knurpht and wolfi323) for helping me out with opensuse 12.2: yast “System Services (Runlevel): Services” very slow: how to investigate.
The solution is to install openldap2, then reboot.
The easiest way is to perform this under sudo:
zypper install openldap2
Somehow in opensuse 12.2 yast, sendmail and apache depend on it (though the yast/zypper software installer don’t recognize the dependency).
Without the reboot, yast was still slow. Not sure why yet.
I will need to check this out in the most current opensuse release.

Unpatched bash allows for remote code execution.
Patch as soon as you can and be aware that the current patches might not be complete.
Many vendors (including Debian, Red Hat, SuSE, Ubuntu) already have patches available: CERT/NIST reveal level 10 bash alert today, 24 September 2014.
This is a long article which explains the why/how/… and has an easy check to see if you are vulnerable: What is the CVE-2014-6271 bash vulnerability and, how do I fix it.
It looks like the current patches aren’t complete yet, but do plug big parts of the hole.
Watch bash CVEs in Ubuntu and CVE-2014-7169 in Ubuntu (and maybe for other nx varieties as well).
Update:
curl https://raw.githubusercontent.com/hannob/bashcheck/master/bashcheck > bashcheck.sh
less bashcheck.sh # check if there is nothing fishy
chmod +x bashcheck.sh && ./bashcheck.sh
rm bashcheck.sh
