installed ubuntu on my mac

I came to the problem that I needed to test native linux/unix virtualisation recently. First, I tried to think of the new test box I have to procure, but then I got the idea that I'm not using my current resources to the full: my MacBook Pro i5 8GB RAM. Found this (see a copy in my Google Drive). It was really easy!

All you need is to do reEFInd bot manager and install Ubuntu afterwards. Worked like a charm! And it is very nice performance of Ubuntu on this metal :)

The only annoyance was that my computer stopped to do sleep normally (from OS X perspective). It needed hard reboot every time after a few hours of sleep. Fortunately, upgrade to Yosemite solved this, probably just a fresh reinstall of anything would have helped.

Enjoy!

shellshock on my systems - no real worries

To determine if your Linux or Unix system is vulnerable, from a command line, type something like this:

env x=’() { :;}; echo vulnerable’ bash -c “echo this is a test”

If the system is vulnerable, the output will be:

vulnerable
this is a test

An unaffected (or patched) system will output:

bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x’
this is a test

or it will say that bash is not present or something else, you figure it out :)

So what about my systems? Here's the list:

• pfSense firewall 2.1.4-RELEASE (amd64), built on Fri Jun 20 12:59:50 EDT 2014, FreeBSD 8.3-RELEASE-p16 : not vulnerable, bash is not there by default :) check /etc/shells if you have it installed
• FreeNAS home server FreeNAS-9.2.1.7-RELEASE-x64 (fdbe9a0), FreeBSD 9.2-RELEASE-p10 #0 r262572+4fb5adc: Wed Aug  6 17:07:16 PDT 2014 : bash present by defeult, system vulnerable, checked jails, bash not present, will wait for the fix in next version, there's good comment on this at the end of this discussion :)
• Mac Darwin Kernel Version 13.3.0: Tue Jun  3 21:27:35 PDT 2014; root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64 : vulnerable, (I think) I haven't played with enabling/opening things, so will be waiting on Apple :)
• Hackintosh Darwin Kernel Version 13.3.0: Tue Jun  3 21:27:35 PDT 2014; root:xnu-2422.110.17~1/RELEASE_X86_64 x86_64 : vulnerable, (I know) I haven't played with enabling/opening things, so will be waiting on Apple
• XBMC based HTPC on Ubuntu 14.04.1 LTS, Linux ___ 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux : not vulnerable
• I haven't hacked into my TV and I won't :)

Good luck to you all!
