There is a lot of angular dashboard seed projects out there. But they are stuffed with a lot of things that might be not necessary to start a project of your own. So I decided to do my own Angular dashboard lean seed project. This project was scaffolded with Angular CLI version 1.4.9. What’s included Angular 5+ & Typescript 2.6.2 Bootstrap …
I wanted to be able to quickly see at any time the CPU load, Memory used, HD load, network etc … on my main home server. I wanted to have that constantly displayed on a screen on top of my server. Of course, one option would be to plug the monitor to the server and crack up a session to display …
I wrote this article as a reminder for myself. I’m using Ubuntu 16.04 server on both sides. I have a server, let’s call it Box1, with full (root file system) LVM encryption. It’s great as it protects my data but the problem is that it needs someone to input the password at boot to decrypt the LVM volume. If the server …
I use ownCloud on a daily basis. I have setup a server years ago, and all my digital life stays there instead of going onto those “I don’t know who, I don’t know where and what they do with it” servers of Dropbox, Google drive etc… Lately, I upgraded from ownCloud 8.0.4 to 8.1, followed all the necessary steps indicated in the …
If you built your own NAS with a PC, a Linux OS and some disks, you will need to monitor the health of your hard drives. Wouldn’t it be nice to know by advance if a hard disk will fail? Being proactive is essential here. And it also works if you only have a Linux workstation… For this, we will use the smartmontools …
Do you need your servers to communicate securely through the WAN or an unsecured LAN? Having some services communicating insecurely that you want to encapsulate in a VPN tunnel? Let’s see how we can have a setup using 2 servers. We could have more but… let’s keep it simple for now. General configuration Before we start, let’s name those 2 linux …
Open a terminal. BEFORE inserting the USB key, check which disks are available:
|
1 2 |
diskutil list |
You should see one or more disks installed on your system like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *250.1 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage 249.2 GB disk0s2 3: Apple_Boot Recovery HD 650.1 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS IntelSSD *248.8 GB disk1 Logical Volume on disk0s2 Unlocked Encrypted |
Insert the USB key. Do a “diskutil list” again. You should see one more disk. This is your USB key. Let’s assume it is /dev/disk2. First we need to convert the ISO file to …
I created this guide for me to keep track of what I’m doing and I’m sure it can be of some help to some people. At this time, I didn’t find an up to date image of Ubuntu server 14.04.2 with WIFI on forums or downloads of Hardkernel site. I decided to create my own. Here is how… If you don’t want to go …
This file system is perfect to be used in a NAS. You can check Why ZFS over EXT4 or other FS at the bottom of this article. Install ZFS Before we can start using ZFS, we need to install it. Simply add the repository to apt-get with the following command:
|
1 2 |
apt-add-repository --yes ppa:zfs-native/stable |
|
1 2 |
apt-get update |
|
1 2 |
apt-get install ubuntu-zfs |
You should get something like this:
