It&#8217;s two days prior to the August meeting, and I&#8217;m working hard to get the most rewards for my efforts.<\/p>\n\n\n\n<p>I realized late Thursday night that getting all the VMs converted to KVM was a strategy I shouldn&#8217;t have tried to include in such a tight timeline.  Fortunately, the system has two 2TB M.2 SSDs, so I didn&#8217;t have to disrupt my efforts to temporarily abandon the KVM strategy &#8212; I just installed ESXI 6.7 onto a USB thumb drive, booted that, and made the second SSD its storage volume.  After that, a quick SCP to get all the working VMs into it, and then some enhancements:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>I built a FOG server and captured a fresh Kali install to it. Then I updated that Kali image (over 1000 packages) and captured that.  So now, if you show up at a meeting and want to play on the CTF, but don&#8217;t have a Kali VM, you can quickly get a current one. (Assuming you have the capability of creating a VM and PXE-booting it).  Not fast going through the wifi (up to 30min to deploy) but I have a crossover adapter coming tomorrow and should be able to route it through a small gigabit switch so that wired imaging will be lightning fast.<\/li><li>Automated startup, and an easy shutdown script to suspend the VMs and avoid data loss.<\/li><li>Most importantly, to combat the issue from last month, the system has been tested to restore from complete power loss, and comes up in a fully usable state.  So I have reduced prep time for the meeting to the following:<ul><li>Plug in, power up the three devices (WOPR Jr, wifi router and gigabit switch)<\/li><li>Set up TP-Link Wifi Extender using the laptop, piggybacking on the library&#8217;s wifi<\/li><\/ul><ul><li>Plug the DC540 wifi router into that for egress.<\/li><li>Clamp the defcon flag for display<\/li><\/ul><\/li><\/ul>\n\n\n\n<p>Interestingly, this graph shows the performance of the NUC with lots of VMs running.  The higher memory line represents 17 linux VMs and 5 Windows VMs running.  When the memory drops lower, that&#8217;s when I shut down the Windows VMs.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1016\" height=\"720\" src=\"http:\/\/dc540.org\/xxx\/wp-content\/uploads\/2019\/08\/Screen-Shot-2019-08-24-at-12.10.09-PM.png\" alt=\"\" class=\"wp-image-401\" srcset=\"https:\/\/dc540.org\/xxx\/wp-content\/uploads\/2019\/08\/Screen-Shot-2019-08-24-at-12.10.09-PM.png 1016w, https:\/\/dc540.org\/xxx\/wp-content\/uploads\/2019\/08\/Screen-Shot-2019-08-24-at-12.10.09-PM-350x248.png 350w, https:\/\/dc540.org\/xxx\/wp-content\/uploads\/2019\/08\/Screen-Shot-2019-08-24-at-12.10.09-PM-300x213.png 300w, https:\/\/dc540.org\/xxx\/wp-content\/uploads\/2019\/08\/Screen-Shot-2019-08-24-at-12.10.09-PM-768x544.png 768w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This is a status report.
