After installing the latest stable version of docker-ce (5:18.09.0~3-0~raspbian-stretch as of the time of writing), Docker would take ages to start after a reboot. Commands would even time out waiting for it. /var/log/daemon.log shows a gap of almost 4 minutes between the attempt to start the Docker Application Container Engine and the first log line […]
So, during spring cleaning, a used iMac was discovered at work. I figured it could be used for something, so I set it up on a table. It only booted to recovery mode, so I had to reinstall it. Simple, right? No, of course not! This is an Apple product. Apple ID needed So, booting […]
So, you resurrected a VM from the cold, damp crypts of the deepest backup dungeons, and now you can’t log in because the VM doesn’t trust the domain server anymore? That’s alright. The Windows Domain will rotate its keys from time to time, and an offline VM snapshot will not know about it. You don’t […]
Introducing a new Cathedral Networks service. The console friendly pastebin that supports binary files. We needed one, so now it exists. Take a look at https://paste.c-net.org/
Tasked with recovering files you don’t have access to through the web interface, you can always find these through the file system if you’re the operator. You could, of course, give yourself access, but let’s save that for another time. Right now we want the files our users removed and/or can’t find. We start by […]
Classic whodunit – the file is gone. Who deleted it? Well, unless you’ve already prepared for this, Windows has no log for you. Sorry. The good news is that this is an excellent time to prepare for the next time. So let’s do that. Enable the auditing of file operations to the Windows Event Log […]
I wrote this tool today, as I was annoyed having to do a bunch of changes to a configuration file on a client site through a restrictive remote tool that doesn’t let you paste or transfer any files for “security reasons” (read: BOFH) It pastes text, files and entire directory structures by simulating keyboard input. […]
If you use Cygwin to mainly manipulate files in your regular Windows filesystem, under /cygdrive/…, you have probably seen this message more than a few times: “The permissions on <node> are incorrectly ordered, which may cause some entries to be ineffective” You have also likely seen “NULL SID” as the top entry in permission lists. […]
Microsoft has apparently messed up their integration of the Hyper-V Manager on Windows 10 with Hyper-V Server hosts, resulting in the above error message showing up on the “Security” tab of virtual machines. So now what do you do if you want to disable Secure Boot to load some Linux distribution that doesn’t support it? […]
I’ve previously presented a manual process for doing this, but lately I’ve had to do it more often, and I figured it was about time for automation. This script will: Run e2fsck on the root file system Erase logfiles, such as bash_history and stuff in /var/log Erase the test.h264 video file Wipe resolv.conf Defragment the […]
