Start ices2 and remote mplayer in one command

To run ices2 on SOURCE_SERVER, and start up mplayer on TARGET_SERVER, and then shutdown ices2 after quitting the remote mplayer, in one command:

ices2 ~/ices-pulse.xml & ssh -t USER@TARGET_SERVER 'mplayer -cache 512 -cache-min 49 http://SOURCE_SERVER:8000/live.ogg' && killall ices2

Left Handed Configuration for Logitech Marble Mouse on Ubuntu

This comes from https://wiki.archlinux.org/index.php/Logitech_Marble_Mouse

Append the following to /usr/share/X11/xorg.conf.d/10-evdev.conf (and then restart X)

#       - - - Logitech Marble Mouse Settings - - -
#
#       The Logitech Marble Mouse buttons are mapped [A-D] from left to right:
#       A (large); B (small) |  C (small); D (large).
#
#       Preferred options for right-handed usage:
#       A = normal click [1]
#       B = middle-click [2]
#       C = middle-click [2]
#       D = right-click [3]
#       Hold button B while rolling trackball to emulate wheel-scrolling.
#
#       Preferred options for left-handed usage:
#       A = right-click [3]
#       B = middle-click [2]
#       C = middle-click [2]
#       D = normal click [1]
#       Hold button C while rolling trackball to emulate wheel-scrolling.
#       Pressing both large buttons simultaneously (b) produces a "back" action.

HiFiBerry, OpenELEC and Raspberry Pi 2

Apart from the last step, these instructions come from HiFiBerry.com here.

Create this file: .config/modules-load.d/hifiberry.conf
And make its contents:

snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_hifiberry_dacplus

Create or edit this file: /storage/.xbmc/userdata/advancedsettings.xml
And make it include this:

<advancedsettings> <video> <defaultplayer>dvdplayer</defaultplayer> <defaultdvdplayer>dvdplayer</defaultdvdplayer> </video> </advancedsettings>

Create this file: /storage/.config/modprobe.d/disable-lirc.conf
And make its contents:

blacklist lirc_rpi

Now a change that isn't in the hifiberry.com instructions. You need to edit the /boot/config.txt file. To do this the RPi needs to be shutdown, pull the SD card out and mount it on another computer. Add to the end of config.txt the following:

dtoverlay=hifiberry-dacplus

Save the file, start up OpenELEC and select HiFiBerry in OpenELEC's audio settings.

2 steps for passwordless SSH login

1. Open terminal and run: ssh-keygen
2. Then: ssh-copy-id remote-user@remote-hostname

If you want to give root ssh access to the remote system (e.g. for rsnapshot) then just run 'sudo su' before those two commands.

RDP rdesktop command

rdesktop -u username -d domain -p password -f -a 24 servername

Fix for rsnapshot not running through cron on raspbian

Edit crontab with:

sudo crontab -e

And then in the crontab text file, before the scheduled tasks are defined add:

MAILTO=""
