Mosquitto MQTT on Raspberry Pi fails on startup

On my Raspberry Pi I want to use the Mosquitto MQTT broker, but if fails to start up as a serivce.

sudo service mosquitto status just gives me
[FAIL] mosquitto is not running ... failed!

The problem was, that the log file was not as expected in /var/log/mosquitto/mosquitto.log because I use tmpfs for /var/log.

To fix the problem, I added these lines in /etc/init.d/mosquitto in the start section:

mkdir /var/log/mosquitto.log

First open the TS File in Avidemux:

For Audio choose MP3 (lame) and finally set the format to AVI. That’s it.

CoRD–RDP Remote Desktop for Mac

I had the very strange problem, that the RDP Client for Mac from Microsoft did not work with nested RDP sessions. That means when I connect from my Mac to my Windows 7 Desktop and from that to a remote Windows Server, the shift key was only working occasionally. Argh!

The solution is CoRD! A fancy RDP Client for Mac ( Works like a charm!

Kerberos Troubleshooting

Hin und wieder darf ich mich mit Kerberos Authentifizierung rumärgern. Vor allem beim Setup von neuen Systemen bringt mich das meist an den Rand der Verzweiflung. Retter in der Not ist da DelegConfig ( Quasi das Schweizer Taschenmesser für die Kerberos Delegierung mit mehreren Servern.
