Common Problems and Solutions

This page is meant to be a comprehensive list of problems and their fixes that can arise anywhere in cmdr from the source code to any problems with any dependencies.

[ERROR] EXCEPTION: Could not connect to server 127.0.0.1:5672

This is the port that rabbitmq-server runs on. Why this error appears is still not certain, but it prevents rabbitmq-server from running. To fix, delete the folder /var/lib/rabbitmq/mnesia and restart rabbitmq-server (sudo /etc/init.d/rabbitmq-server restart). You can then restart cmdr.

If you run into problems getting Xorg to start up and see an error similar to the one above it may have something to do with evtouch being installed. In ```/usr/lib/X11/xorg.conf.d/``` there are a few different configuration files. If there is a evtouch one, probably named ```10-evtouch.conf``` rename it or remove it. For example, put it in a bak/ directory in that same location. This was preventing Xorg from working properly even with the evdev driver setting in Xorg.conf. It seemed the Xorg somewhere used this ```10-evtouch.conf``` configuration file, which was missing a MatchDevicePath directive which threw the ```(EE) ioctl EVIOCGNAME failed: Inappropriate ioctl for device``` error.

### No Network Connection

Check what the network interfaces are: ```ifconfig -a```

To request a DHCP lease for an interface, do ```sudo dhclient $interface```
(where $interface is whatever network interface you want the DHCP lease on)
