With fresh installation of Fedora 28 I wasn’t able to play any downloaded Japanese animations with the default movie player – Dragon player. My other machine which also runs Fedora 28 could play the movie fine. Without any doubts I must have installed some additional codecs on that machine. But which codecs? Like last time, Google I must search. I’m going to write this post so I wouldn’t have to repeatedly search for the same solution....
At work, we want to backup an external disk that’s connected to the Mac machine using rsnapshot. In order to do that, the external drive needs to be mounted, and this happens when a user logs in to the Mac. The problem is that when nobody logs in, the external drive is not mounted and rsnapshot will fail. The fix should be easy if there is away to mount the external drive without a user logs in....
I have a FreeBSD server which used to run of a smaller SSD drive. When replaced with a larger capacity SSD by using dd command to clone the disk, there is free space allocated. I want to extend the existing zroot pool to use this space. The following describes how I achieve this with the help of a forum post. Let’s list some information about the zroot pool: root@nas:~ # zfs list zroot NAME USED AVAIL REFER MOUNTPOINT zroot 4....
I have a Dell R730 server at work, which connects to a back-end storage with optical fiber cables. In addition, the server itself also has 6 disks. Two of the disks have already been configured as RAID1 and has the operating system installed on it. Today, I want to configure the remaining 4 disks as RAID10, and setup logical volume on it. The first part was easy. All I had to do was to login to the Integrated Dell Remote Access Controller (iDRAC), and create a new Virtual Disk from the 4 physical disks....
TLDR; just follow this guide. At home I run DHCP and DNS servers on Odroid U3, a system on a chip (SoC) computer. This allows me to have lots of control over my home network and most importantly – fun. I also run some web sites and Postgresql databases for testing purposes. The SoC computer runs Ubuntu 16.04 as the operating system. Recently, the Odroid U3 died. A coworker also has an SoC, an Odroid XU4....
urxvt or unicode-rxvt is a terminal simulator like Gnome-terminal or Konsole. Recently I’m trying to switch to use i3 (i3-gaps), a tiling windows manager, and urxvt is good compliment to i3. Unlike Gnome-terminal or Konsole, the font name and size for urxvt are configured in ~/.Xresources. To make change to font size, for example, I’d edit ~/.Xresources, reload it with xrdb ~/.Xresources, and finally close and re-open urxvt itself. Though there is no built-in function to allow changing font size on the fly, urxvt allows us to do this via extensions....
Work recently acquired a few MacBook laptops to be used and shared by staff. Though the computing staff is not expected to have immense knowledge about OS X, when things break down we are the first point of contact. The last time I used a Mac machine extensively was around 2007. Then I switched to Debian and could never look back. Anyway, there must be lot of new things and I’ll try document or post snippets here as I learn new things....
The other day, after successfully building Docker-ce 17.06.0-dev for Odroid C2 which has ARMv8 CPU, i couldn’t find Docker client. Maybe it was just me not building the Docker engine correctly. Anyway, after some more times, I also managed building the Docker client for the Odroid C2. It turned out, like many things, it wasn’t that hard after you figured it out. It’s worth to note too that the build instruction on https://github....
Before getting into how to change a user’s password on FreeBSD, let’s have a quick revision on how that can be done on a Linux system. As a user we can change the password by typing: Or with a root account, we can change/set the password for another user: How about a FreeBSD? It should be the same way as how it’s done on Linux right? Right? Well, not quite....
Sure, you Linux gurus must be laughing at me to see this post. However, this is my 2nd time needing to remove a user’s password and I had to Google for it! So here is just a quick tip to mind your truly: In case you’re wondering why I need to remove a password for an account, it’s for my 4 year old daughter who enjoys playing supertuxcart. She wants to have her own user account on a Fedora 24 box without a password....
