How to setup o.e.ecf.examples.raspberrypi.* on the pi [message #1472399] Thu, 13 November 2014 16:13 Go to next message
Eclipse UserFriend
Hello

I am trying to run the example org.eclipse.ecf.examples.raspberrypi.management on a raspberry pi following this tutorial. After starting the programm the error: "Cannot assign requested address" is thrown repeatedly.

I'm using the ip address of my pi (192.168.1.121) as the host name and I have checked that the port 3288 is not used before. After the startup I can see the port 3288 listening, but I can't find the pi in the Service Discovery view.

In the OSGi log I can see ch.ethz.iks.slp trying to connect to 127.0.1.1. Any pointers on why this might fail and what I can do about it are greatly appriciated!

Versions:
- Equinox Target Components 3.10.0
- ECF OSGi Remote Services SDK 3.9.0
with dependencies
working in Luna RC1

Hi Christoph,

try adding -net.slp.interfaces=192.168.1.121 to the list of java
properties to make jSLP bind to this (external) interface.

Hi Markus

thanks for your input! That gets me one step further, but I still get an exception during start up and I still see 127.0.1.1 in the middle of it.

And I still don't see the pi in the Service Discovery view.

Any ideas what else I could try?

Hi Christoph,

what is the content of /etc/hosts and the output of ifconfig on the Pi?

Te pi01 says that it is on interface 127... You also have to add the property on the remote end.

Cheers,

Hi Markus, hi Wim,

thanks for your replies! The weekend has been busy, but now I'm eager to get this working.

@Wim: Thanks for your inspirational talk at ECE in Ludwigsburg! Your presentation was the reason I wanted to try this stuff myself Smile

I don't know what you mean with "add the property on the remote end". I compared my script to the start script of your pipolos and it looks like you're basically doing the same thing, in the sense that i'm also setting net.slp.interfaces and ecf.generic.server.hostname when I start the server on the pi.

I get the feeling that my issue is probably not connected to ECF but has more to do with the setup of the pi itself. I admit that I am not very komfortable with linux yet.

ifconfig

I've also tried this with lan (eth0) which uses the ip 192.168.1.120 with the same result. The ip is provided by a dhcp server which reserves 192.168.1.121 for pi01 over wlan0.

/etc/hosts

127.0.1.1       pi01

I tried to change the last line to "192.168.1.121 pi01" which leads to

Ok. I've finally got it working! The problem was the missing loopback network interface lo which needed to be configured.
As a reference to others: The output of ifconfig should also include someting like this:
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:4089 errors:0 dropped:0 overruns:0 frame:0
          TX packets:4089 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:210891 (205.9 KiB)  TX bytes:210891 (205.9 KiB)

Hi Christoph,

thanks for the follow up. Without a loopback interface, SLP cannot
detect a locally running Directory Agent [1].

What Raspberry Pi image are you running? It would be good to know if it
has no loopback interface by default.

I messed this up myself when I configured the wlan connection Embarrassed . The default is fine.

Cool! and thank you for your compliments.

Are you also running the egg interface? Please note that out of the box pipolos uses a slightly newer version of the raspberry pi examples. In addition, pipolos uses JmDNS and not slp for discovery.

The egg interface can be found here: https://github.com/wimjongman/eggclient

Please note that you also need to supply the java properties:

-Decf.generic.server.hostname=192.168.1.33
-Dnet.mdns.interface=192.168.1.33 // (without the "j") to tell jmdns which network to use
-Dadmin=true // activates the cooking pin

See egg.ini for details.

I'll get around to the client after I've played with the basics for a while. I managed to run Scotts original GPIO example today. The next thing I will do is try your enhancements.

Out of curiosity: Why did you choose JmDNS over SLP for pipolos? They seem rather similar and both target LANs?
