HTTP Server binded on http://localhost:8000 --- ERROR - [Errno 19] No such device

[Dominik]

Hello Eric,

i got a new problem, were i don't know how to find the reason why.

If i start webiopi automatically by booting i get this error in the log file:

2013-04-19 16:50:57 - WebIOPi - INFO - Starting WebIOPi/0.6.0/Python2.7

Sometimes (for example starting with sudo /etc/init.d/webiopi start) it works and then the logfile looks like that:

2013-04-19 16:50:37 - WebIOPi - INFO - HTTP Server stopped


The differece is, that if it not works, HTTP Server binded on http://localhost:8000/, if it works fine, HTTP Server binded on http://192.168.178.41:8000/.

Do you have any Idea? Is it maybe a timing problem doring boot process and getting IP-Adress?

Thanks in advance
Dominik

Disable coap multicast in config file.

It look like your network interface (wifi dongle I guess) has some trouble with multicast binding.

IP displayed is just a hint to access the Pi.

WebIOPi always try to bind to all IP availables.

Hello Eric,

thanks agin for your excelent advice. Now, all my Pis run with WebIOPi without a problem.

Thanks so much!!!!!

The long story:

	starting with:
	unmodified /etc/webiopi/config
	the ip-address from DHCP ( ...100 - ...149 ) on a cabled network
	it works fine ( great tool !!)
	and stops with ctrl-c
