  In my day to day life I use 4 devices running Arch Linux .  XPS13 laptop Ryzen 7 3700X on a B550 itx system Ryzen 3 3100 on a A520 as my home server Xeon E3-1260L on a LGA 1155 running Next Cloud and a web server In this post I will outline the differences in my Arch Linux install among these devices. Before proceeding I should point out that using a rolling release on a server environment poses additional challenges that generally cannot be justified for production systems. The first step is to boot using an Arch Linux USB. Then I generally start by creating a 260MB EFI partition using fdisk. The boot partition needs to be formatted as a Fat 32 partition.  mkfs.fat -F32 /dev/sda1 The rest of the partitions are going to be on LVM . First step is to create a partition in the remainder of the disk and choose LVM as the partition type. Once done I would create the physical volume and a volume group. pvcreate /dev/sda2 vgcreate vgmain /dev/sda2 Now I would create the root ...

 Let me start by telling a little bit of the back story. Recently I build a mini ITX desktop PC to help me with my more resource intensive programming work. I used a all in one liquid cooler in this PC. ( Kraken X63 ). Setting something like this in Windows is quite straight forward, not so much in Linux. In this article I will detail what I did to get it working the way I wanted.  First problem to solve was to find a driver/controller software for the cooler, that works in Linux. These coolers come with only windows driver/controller software with no official Linux support. Thanks to the awesome open source community there is a cross platform tool that I can use to talk to the API of the liquid cooler which is called liquidctl . To be more specific I had to use an experimental branch of this tool that supported the API version of my hardware.  Installation is quite straight forward. My preferred Linux distro is Arch . I used an already ported AUR repository of the mainl...

 In this series of posts I'm going to outline the process I used to create my own Nextcloud server.  Network Setup First step is to prepare my network. I'm planning to host this at home. Due to obvious security concerns I don't want to host this on my home network. I used pfSense  to achieve what I want. The pfSense setup is outside the scope of this post. If you do need help or is curious about setting up pfSense let me know. Given below is an overview diagram of my network,  The basic firewall rules in this network are Server can't talk to the switch.  Server can't talk to the pfSense router interface Server interface has Suricata IDS/IPS running.  Drive Preparation and Encryption Secure erase the drive.  Note: The drive I used was an old HDD. What I didn't notice was that the partition table was of type DOS. Had to change that to GPT and repeat this process in order for it to work. I'm going to use a 250GB HDD for my instalation (not a SSD). First...

 In this article I will detail the steps I followed to install Arch Linux in my XPS 13 9300. It came with windows 10 preinstalled.  My main references during the process was, installation_guide [Arch Wiki] Dell_XPS_13_(9300) [Arch Wiki] Prerequisites The first step is to change the SATA mode from "RAID" to "AHCI". Without doing this the linux installation can't identify the nvme drive on the laptop. This involves going through a few steps.  Boot into windows and run the following commands Open a command promt with admin rights bcdedit /set {current} safeboot minimal Restart into bios and change the SATA mode to AHCI Boot back to windows and open an admin command prompt bcdedit /deletevalue {current} safeboot When I run  bcdedit /enum it doesn't show "safeboot" any more.  Next I disabled fast startup on windows. I'm doing this as I may choose to mount windows partitions when I'm on linux, and fast startup setting is known to cause issues. I...

In this post I'm going to talk about why and how I moved my Open Media Vault Network Attached Storage system to my Ubuntu server. In my previous posts I talked about my OMV NAS. In my NAS I have the following things set up. SMB shares that can be accessed by both Windows and Linux machines Custom user permissions Automated backups Metrics and logging In an attempt to be more frugal I'm trying to reduce the number of servers in my home lab. So lets talk through the process of moving this setup from OMV to Ubuntu. What's involved,  Mounting multiple USB hard disks to the same location between reboots Creating samba shares in Ubuntu server Setting up SMB in windows client machines Automated backups using rsync and cron Metrics and logging Mounting USB drives permanently As mentioned before I'm using 3 USB hard drives for storage and backup. These USB drives needs to be mounted to the same location all the time because the SMB shares and the r...
