Käyttäjä:Masa

masa on noob. masa on myöskin sähkötekniikkaa "opiskeleva" noob. masa ylläpitää omaa palvelintaan, jonka nimi on tällä hetkellä quad. quadilla pyörii irssi, webbiserveri, pellettipolttimen logitussoftat, git-repoja, Minecraft-palvelimia ja toisinaan sekalaisia muitakin pelipalvelimia.

masa's random collection of Linux configuration stuffs

Disable the Recently used files list in GTK+ 2.x and GTK+ 3.x

In GTK+ 2.x

rm ~/.local/share/recently-used.xbel
echo gtk-recent-files-max-age=0 >> ~/.gtkrc-2.0

Note: At least with LXAppearance installed, add that config value to the file ~/.gtkrc-2.0.mine instead!

In GTK+ 3.x

rm ~/.local/share/recently-used.xbel
echo gtk-recent-files-max-age=0 >> ~/.config/gtk-3.0/settings.ini
echo gtk-recent-files-limit=0 >> ~/.config/gtk-3.0/settings.ini

Note: If the file didn't exist, add "[Settings]" to the top of it!

Swap the left and right channels with pulseaudio

Copy the following config:

cp -pi /etc/pulse/default.pa ~/.pulse/default.pa

Edit the config, add the following two lines to the end:

load-module module-remap-sink sink_name=reverse-stereo master=1 channels=2 master_channel_map=front-right,front-left channel_map=front-left,front-right
set-default-sink reverse-stereo

Restart PulseAudio by running pactl exit at the command line.

This configuration makes a few basic assumptions: that the card you're reversing the channels of is card 0; that you only have to deal with 2 channels; and that those channels are called front-left and front-right. If you have a videocard with HDMI out, it is likely the analog out of your motherboard will be card 1, not 0; so master=1.

Some useful commands

Record an area from the screen

Record a region from screen, with audio (can be used to record for example Minecraft). Shows the region outlines to align the window.

ffmpeg -f x11grab -show_region 1 -r 25 -s 1280x720 -i :0.0+500,80 -c:v libx264 -preset fast -crf 22 -f alsa -i pulse -c:a libvorbis -b:a 96k -threads 0 -f matroska sda6/minecraft_withertaistelu_overview_2012-11-24_2.mkv

Another sometimes useful option fo x11grab:
-follow_mouse centered|<PIXELS>

When it is specified with "centered", the grabbing region follows the mouse pointer and keeps the pointer at the center of region; otherwise, the region follows only when the mouse pointer reaches within PIXELS (greater than zero) to the edge of region.

Encode images into a (timelapse) video

ffmpeg -f image2 -i ms_all/shot_%06d.png -r 25 -c:v libx264 -preset medium -crf 25 -an -threads 0 -f matroska rakennustapahtuma_2012-11-03_crf25_medium.mkv

Some random web stuff

Generate a SSL-key:

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -nodes -days 1001

Random shell scripts

Safely shutdown a SATA hard drive (spins it down). Umount first! Usage example: scsiremove /dev/sdb

/usr/local/bin/scsiremove (needs sys-block/scsiadd and sys-fs/lsscsi):

#!/bin/sh

if [ $# -ne 1 ]; then
        echo "Usage: $0 <device>"
        exit 1
fi

if ! which lsscsi >/dev/null 2>&1; then
        echo "Error: lsscsi not installed";
        exit 1
fi

if ! which scsiadd >/dev/null 2>&1; then
        echo "Error: scsiadd not installed"
        exit 1
fi

device=`lsscsi | grep $1`

if [ -z "$device" ]; then
        echo "Error: could not find device: $1"
        exit 1
fi

hcil=`echo $device | awk \
'{split(substr($0, 2, 7),a,":"); print a[1], a[2], a[3], a[4]}'`

scsiadd -r $hcil

---

Merge together video files in matroska containers (needs media-video/mkvtoolnix).

/usr/local/bin/merge.sh:

#!/bin/bash

ALL="empty"
DSTDIR=${1}
FILES=${2}

for i in $(ls ${FILES}*)
do
        if [ "$ALL" = "empty" ]; then
                ALL=${i}
                FIRST=${i}
        else
                ALL="${ALL} + ${i}"
        fi
done

#COMBINED=$(basename $FIRST | sed "s/\.mkv/_all.mkv/")
COMBINED=`basename ${FIRST} | sed "s/\.\([a-zA-Z0-9]\{1,10\}\)$/_all\.\1/"`

if [ -f "${DSTDIR}${COMBINED}" ];
then
        echo "Error: the target file already exists!"
        exit
fi

#echo "mkvmerge $ALL -o ${DSTDIR}${COMBINED}"
mkvmerge $ALL -o ${DSTDIR}${COMBINED}
touch ${DSTDIR}${COMBINED} -r ${FIRST}

---

Encode videos into matroska container, with Ogg Vorbis audio and h.264 video (with x264 library). Needs media-video/ffmpeg, media-libs/libvorbis and media-libs/x264.

encode.sh:

#!/bin/bash

SRCDIR=/home/masa/Media/Fraps/Fraps/
DSTDIR=/home/masa/f/

SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

for i in $(ls ${SRCDIR}javaw*avi)

A script I used to symlink multishot screenshots into linearly increasingly named ones for ffmpeg encoding:

num=0

if [ $# -ne 1 ];
then

		#echo "$j -> ${num}"
		#printf "$j -> shot_%06d.png\n" ${num}

		#echo $name
		#echo "ln -s /home/masa/ms/${i}/${j} /home/masa/ms_all/${name}"

Filter out cron messages from /var/log/messages (using syslog-ng logger)

In /etc/syslog-ng/syslog-ng.conf, add and change:

# Create a filter:
filter f_croninfo { level(info) and not facility(cron); };
# for example before the line:
destination messages { file("/var/log/messages"); };

# Add the following and comment the original line
log { source(src); filter(f_croninfo); destination(messages); };
#log { source(src); destination(messages); };
