So, running a couple of Hyper-V machines, and needing to determine their local IP addresses to connect to them. As long as the Hyper-V Integration Services are installed (apt-get install hyperv-daemons on Debian-based distributions), PowerShell on the host machine will have access to the IP addresses of the client machine. Without the Integration Services, PowerShell […]
I recently had need of a service that would return your exact query to you for web client (or proxy) development purposes, in a case where using Fiddler, Wireshark, tcpdump et.al. was proving difficult for various reasons. The solution became the C-Net Echo Service, available at https://echo.c-net.org/ (and over plain HTTP if you need it). […]
curl: (60) SSL certificate problem: unable to get local issuer certificateMore details here: https://curl.haxx.se/docs/sslcerts.html So curl fails to access sites over https, even if ca-certificates is installed in your Docker container? You need to force a certificate rehash. Why this is not done by default escapes me. /usr/bin/c_rehash curl should be happy now. Enjoy!
I wanted some GLaDOS-like sounds for my home automation system. I found this project, which doesn’t work anymore as of writing, as the synthesis server is offline. Thus, my weekend project turned into a week-long evening project. But that’s fine, as the result is cool: The new GLaDOS Voice Generator is here! Enjoy.
We recently encountered this in a production environment: A customer had installed a new certificate, and this exception began showing up in the logs. Luckily, the application was smart enough to at least fall back on using the previous (not yet expired) certificate, so no downtime occurred. Turns out the customer had been provided with […]
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 […]
