Last night when I was updating my Proxmox server I restarted it. But I wasn’t able to connect to it after five minutes, so I connected a monitor to it and saw that a hard drive wasn’t being detected. I Identified the failed drive, replaced it, and powered the server up.
While I was backing up a few containers in Proxmox today, one of them became unresponsive. I tried to cancel the backup but it just became locked. Restarting the server didn’t help, so after browsing the Proxmox support forms, I found the following solution detailed below.
Every time you log in to Proxmox or update it, there’s an error that pops up telling you that you haven’t purchased an enterprise license key. If you are using Proxmox in an enterprise environment, I would recommend buying a license (even though it’s not required). You’ll get access to an enterprise repository that contains stable security and software updates. But if you run Proxmox non-commercially and want to remove the no subscription error messages, follow the instructions below.
A few day ago when I was upgrading some of my servers, I notice that Zentyal was showing as being up to date in the dashboard, but there was also an alert in the dashboard that said that the server was missing an security update. When I logged into it over SSH and tried to manually install updated, I encountered the following error message.
A few months ago, I switch from a Windows-based Active Directory environment and switch to a Linux alternative called Zentyal. And so far, everything works great. I was able to recreate my AD structure and recreate new group policies based on the ones from my old install.
I’ve been putting off expanding the storage space on my Nextcloud VM for a couple of months now. However, a few days ago, the storage space hit less than a few hundred megabytes and I wasn’t able to login or upload any new files, so I was then forced to upgrade it and here are the steps I followed.
Sometimes you need to access a network share that requires an active directory authentication, but, you’re on a PC that’s not part of the domain. Saving the script below as a .bat file and replacing the parts that say “Server” with the actual name or IP of your server will allow your PC to access any network share with active directory credentials. Mostly, this is useful when you only need temporary access to a share, but don’t want to go through the whole network share mounting process.
Recently, I’ve been installing Lets Encrypt SSL certificates on all of the network devices on my network. This past week, I’ve been working with Dell iDRAC cards (a remote access card that allows you to manage servers remotely, even when they are powered off) in some of my servers. I got tired of clicking through the SSL warning whenever I would try to access one of my iDRAC cards, so I created a script to replace the self-signed certificate on the card.
So a few months ago, I was having trouble installing updates on one of my Ubuntu Linux servers. When I ran,
sudo apt-get upgrade I got the following error message listed below.
Updating SSL certificates is one of those repetitive and boring tasks that you have to do managing a web server. But, it’s also one of the most important when it comes to the security of your website. So lets automate it!
