Stuff about the superior OS

Running PulseAudio in system mode with TCP listening on Debian Wheezy

On this thin client I’ve set up, I wanted pulseaudio to run before logging in, and not have any specific users on the machine. System mode was called for. On Wheezy, pulseaudio is by default configured for per-user sessions. To remedy this, edit /etc/default/pulseaudio, putting PULSEAUDIO_SYSTEM_START=1 Then, edit /etc/pulse/system.pa – this is the file that […]

One-time passwords in Debian Wheezy with libpam-otpw

While public and private keys with decent pass-phrases are an excellent way of logging in securely to a remote system, it’s sometimes simply not feasible. Your Android device which normally does the job for you is out of battery, you are in a remote country with only a wired connection in a shady Internet cafĂ©, […]

Using CheckInstall to track custom source downloads on Debian

CheckInstall keeps track of all files installed by a “make install” or equivalent, creates a Slackware, RPM, or Debian package with those files, and adds it to the installed packages database, allowing for easy package removal or distribution.

STOP will pause a process (not actually stop it – it doesn’t die) CONT continues a […]

Linux on Mac Mini – power on after power loss

The Mac Mini doesn’t save this information in its BIOS (or equivalent), so you need to set it on each boot. I use my distribution’s /etc/rc.local file for this. Either way, these are the commands to run (copy, and uncomment the correct line for your Mini): ## PPC Mac Mini #echo server_mode=1 > /proc/pmu/options ## […]
