NFS allows to share files and folders over network and is much much faster than samba while using way less resources. To setup a NFS server on Fedora 26 install: $ dnf install nfs-utils Shared directories are listed in the following configuration file: --- # Syntax # <path> <ipaddr>(<option>) /home/user/Public 192.168.0.0/255.255.255.0(ro,sync) More information can be found here: Fedora NFS administration guide. In the above example, the the directory ‘/home/user/Public’ can be accessed by every client in the same LAN with read-only permissions. In case SELinux is active and enforcing rules some further configuration might be required: …

Handbrake cannot be installed from default repos nor rpmfusion, to get it on Fedora 25 there are two other options: use negativo17 third party repository; compile from source. The first option is, but that is my opinion, subpar because I don’t trust third party repositories; option two is what is left. Download the source code from git and install some dependencies: $ git clone https://github.com/HandBrake/HandBrake.git $ sudo dnf install dbus-glib-devel gstreamer1-devel gstreamer1-plugins-base-devel intltool libgudev1-devel libnotify-devel webkitgtk3-devel libgudev-devel dbus-glib-devel webkitgtk3-devel gstream-devel libnotify-devel gstreamer1-devel gstreamer1-plugins-base-devel lame-devel opus-devel fribidi-devel libass-devel libtheora-devel x264-devel nasm Like I do with every other program I like to keep as much up to date as possible, I have a small script to take care of compilation, installation and upgrade processes for me. …

This does not really works, read this: https://nagg.eu/monitor-hard-disk-smart-status-in-python/ First of all install smartmontools, it has the same name on pretty much every distro: $ emerge -a1 smartmontools Proceed to edit its configuration file, at the bottom of the file there is a quick explaination of all the available parameters: cat/etc/smartd.conf --- DEVICESCAN -H -R 1 -R 5 -R 7 -R 10 -R 11 -R 196 -R 197 -R 199 -R 200 -m user@domain.tld -n standby,10,q Parameter -H tells smartd to check the result of overall-health self-assesment test which is pretty much useless, -R is used to specify a single SMART attribute, if its value changes a mail is sent to user@domain.tld. To send emails a MTA must be installed, in centos that is sendmail, in gentoo it is not strictly necessary to have a full fledget MTA installed, nullmailer will suffice. If it is not already installed: …

RawTherapee from my experience is by far the best program to manipulate RAF files, it’s demosaic algorithm for Fujifilm X-Trans sensors is astonishingly good. Too bad that, like for Darktable, the version included in Fedora’s repos is outdated to say the least. To install from source first install some dependecies: $ sudo dnf install bzip2-devel cmake exiv2-devel expat-devel fftw-devel gcc-c++ glib2-devel glibmm24-devel gtk3-devel gtkmm30-devel lcms2-devel libcanberra-devel libiptcdata-devel libjpeg-turbo-devel libpng-devel libsigc++20-devel libtiff-devel zlib-devel gtkmm24-devel lensfun-devel Git clone and install …

Darktable documentation on this matter is somewhat fragmented, so I figure a small how-to on how to install it from source on Fedora 23 could be useful. The version included in the official repositories is really old (version 1.6.9 as per today) and is missing some important presets for many widely used cameras. The latest version source code archive can be downloaded from here: https://github.com/darktable-org/darktable/releases. Before compiling and installing the software the following dependencies must be installed: …

Every time I have to setup a software RAID in Linux using mdadm I forget something, this time I am writing it down once and for all (or at least I hope so). For the sake of simplicity I will use the creation of a RAID1 as example but this very same procedure can be applied for any other kind of RAID. RAID array creation 1. Partition the drives This step must be repeated for each drive of the array (/dev/sdb and /dev/sdc in my case). …

XFS just like EXT4 (I wrote a post about it last year) supports online defragmentation, to manage those volumes on CentOS and Fedora xfsprogs package is needed. Fragmentation level of XFS volumes can be checked with the command: [root@CentOS ~]$ xfs_db -c frag -r /dev/sdb1 actual 4491, ideal 4006, fragmentation factor 10.80% To perform online defragmentation of XFS volumes run the following command: …

Since every time I am about to install Vim I forgot how to set it up, set it as default system wide text editor and so on I figure I’ll write it down once and for all. First of all let’s install Vim, specifically the so called enhanced version which is capable of loading plugins and colorschemes: [user@Fedora ~]# sudo dnf install vim ### powerline plugin [user@Fedora ~]# sudo dnf install vim-plugin-powerline I personally really like molokay colorscheme from tomasr; putting it in the default colorscheme directory does the trick if we want to use it for every user. …

EXT4 is usually pretty good at keeping files fragmentation at minimum, but, sometimes, especially if dealing with really huge files, some fragmentation may actually occur. Luckily EXT4 supports online defragmentation, command fsck displays, among other things, fragmentation percentage: [root@fedora ~]$ fsck.ext4 -fvn /dev/sda1 e2fsck 1.42.12 (29-Aug-2014) Warning! /dev/sda1 is mounted. Warning: skipping journal recovery because doing a read-only filesystem check. Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information 429 inodes used (1.31%, out of 32768) **5 non-contiguous files (1.2%)** 1 non-contiguous directory (0.2%) # of inodes with ind/dind/tind blocks: 0/0/0 Extent depth histogram: 420 45161 blocks used (34.46%, out of 131072) 0 bad blocks 1 large file 402 regular files 17 directories 0 character device files 0 block device files 0 fifos 0 links 1 symbolic link (1 fast symbolic link) 0 sockets ------------ 420 files The command e4defrag, which is contained in e2fsprogs, can be used to perform online defragmentation of EXT4 volumes. …

Let’s say we have a big single FLAC file we want to split into multiple files, we are on Fedora and we don’t want to use anything but the command line. First of all: [root@fedora ~]$ yum install lame ffmpeg shntool cuetools To split the single FLAC file run: [user@fedora ~]$ shnsplit -o flac -f file_name.cue -t "%n - %p - %t" file_name.flac This will produce n single files, -t parameter is used to specify file name format (in this case: track_number – performer – track_name). To copy metadata from CUE to the single files run: …
