I have encountered today at work a situation where I had to know which established connections are using TCP keepalive and which are not.
If you do not know what TCP keepalive is, check out this link. It explains EVERYTHING! :)
You have this old server, it does it's job correctly and you forgot about it. More important, you forget to update it's packages from time to time.
Well, you remember about it but meanwhile this OS has become obsolete and the apt sources are not valid anymore. What to do?
Create another server with new OS and migrate the application/data?
Upgrade the existing server?
Hold on, you do not want to upgrade for now? Just want to update the existing OS? OK, I have a solution for that too.
In this episode I am presenting the dash camera Viofo A139 Quad HD which means 2K.
Using it few month already I can say it is quite good, with quality recordings (back and front) and reliable.
Mixed with a wireless remote and hardwire kit, you can do more like:
- lock a video without the need to reach the camera
- have the camera stop/start with the engine
- parking mode
I am pretty excited to show you probably the best gaming headset I have ever had. I have used for a while Beats solo 3 which are great but are on ear. I wanted something over ear.
I have tested also Steelseries Arctis Pro and Lenovo H600 wireless but so far these ones won for a simple reason: I have used them over 12 hours straight and I felt no discomfort! It is something...
In plus the drivers are great and you can push them hard.
I have upgraded to Ventura and while the modifications are not bad, Apple managed to wreck something that was working very well on previous macOS versions and also on countless linux servers around the world. Yes, I am talking about Samba.
I had an issue a couple of days ago in which I had the /docker filesystem full and unable to pinpoint exactly which docker container is using it.
Fortunately docker comes with powerful utilities to help you out with this.
Follow what comes if curious.
How to check how docker is using the system space:
The following commands even if they are close they provide different output. the -v option will give you way more details docker system df -v docker system df
You have installed vmware tools provided by your ESXi host but you see this message on some servers: "VMware Tools is installed and supported, but a newer version is available on the host."
If you carefully read VMware documentation you will find out they recommend using open-vm-tools instead of VMware tools, as mentioned in the article (link at the end).
Improved stability, automatic updates, smaller footprint, package optimised for each distribution are some of the reason behind this recommendation.
I attached a disk one day and was impossible to create datastore on it via web interface.
Well, did not thought much about it and went directly on command line, via ssh and if you are curious, please follow.
I got bored and thought if I can mix up an old PC with a newer(ish) graphics adapter so I took my old 2009 server from the storage and added on it GTX 1050 Ti.
The results were spectacular and I am sharing with you this experience.
You are here because you cannot find glances via apt, right?
I got into the same issue but differently. I removed glances because it was giving the following error: glances AttributeError: 'ThreadScanner' object has no attribute 'isAlive'.
And when I attempted to reinstall it back, SURPRISE! Not available :D
Actually you cannot resize the OS partition on an existing ESXi installation but you can backup the configuration, reinstall with the right options and restore back the configuration.
You could probably also migrate during the installation process but I haven't tested that yet.
