Image with no hostname

[Andrea Gabellini]

Hello Federico,

I'm new to OpenWisp and I'm trying it.

Usually I use the Image Generator to build my OpenWRT firmware. I add and remove packeges and my own configuration. I also added the openwisp-config agent.

The image generated has no hostname. So the command "uci get system.@system[0].hostname" returns an empty string and the agent returns the error:

Tue Jun 21 11:56:32 2016 daemon.info openwisp: Registering new device

Tue Jun 21 11:56:32 2016 daemon.err openwisp: Registration failed! error: missing required parameter "name"

Adding  the default hostname (OpenWrt) in the configuration solves the problem and now the AP registers itself to the controller. But I get the error:

Tue Jun 21 12:06:15 2016 daemon.err openwisp: Failed to retrieve checksum: HTTP/1.1 500 Internal Server Error

In the nginx logs I can't find any useful info. But I don't know nginx. I use Apache ;-). If you tell me how to debug server side I can do it.

Thanks,

Andrea

Hi Andrea,

I did not know there could be a case in which there is no hostname. I will address it right now as I'm working on it and will release a new version soon.

Regarding the 500 Internal Server Error, it's most probably an application error which is not related to nginx, so you will have to check the application log which should be located in <path-to-app>/log/error.log.

Let me know what you find so if it's a bug I can fix it asap.

Hi Federico,

the empty hostname is strange, but I notice it few month ago. I remember that the version that you can download from the main site contains "OpenWrt" as the hostname. But there is no default in the Image builder.

This is the app log:

Oh right, I see. I fixed that issue with this commit:

https://github.com/openwisp/django-netjsonconfig/commit/ddb6a13241b0d5e371269deb53c103344d335dff

But I realized just now I never issued a new stable release containing that change, so I guess you are using the latest stable release.

I will issue a new release of django-netjsonconfig now to fix this.

Federico

[Andrea Gabellini]

Hi  Federico,

yes, I use stable release for both the agent and the controller.

Do you suggests to use the devel versions?

Andrea

[Federico Capoano]

I just released a new stable version:

https://pypi.python.org/pypi/django-netjsonconfig/0.3.2

I am currently using only the development versions, but I am doing this because things are moving fast.

We need to pay more attention to stable versions.

Federico

[Andrea Gabellini]

Hi Federico,

I just updated the django app to 0.3.2 and installed the devel version of the agent.

A new flashed Picostation, with OpenWrt as hostname, register itself succefully and I didn't get errors like those I reported.

But changing the configuration (hostname only) on the controller doesn't apply to the AP.

The log report this:

Wed Jun 22 10:46:54 2016 daemon.info openwisp: Configuration in controller has changed

Wed Jun 22 10:46:55 2016 daemon.info openwisp: Testing configuration

Wed Jun 22 10:46:55 2016 daemon.crit openwisp: Could not update configuration, openwisp-update-config exit code was 1

Wed Jun 22 10:46:56 2016 daemon.info openwisp: Configuration test succeded

Wed Jun 22 10:46:57 2016 daemon.info openwisp: Configuration applied

The agent config:

config controller 'http'

option url 'https://xxxxxx'

option interval '120'

option verify_ssl '0'

option consistent_key '1'

option merge_config '1'

option test_config '1'

list unmanaged 'system.@led'

list unmanaged 'network.loopback'

list unmanaged 'network.@switch'

list unmanaged 'network.@switch_vlan'

option connect_timeout '5'

option max_time '15'

option capath '/etc/ssl/certs'

option uuid 'xxxx'

option key 'xxxx'

How can I debug openwisp-update-config ?

Andrea

[Federico Capoano]

Try to run it by itself:

openwisp-update-config

What error do you get?

Not good at all.

Which OpenWRT version are you testing?

Federico

[Andrea Gabellini]

I'm using 15.05.01

using the stable versions of two day ago it works

[Federico Capoano]

I completed to introduce an important change just in these last 3 days. But I am testing it on trunk (LEDE master, to be corrext), so today I have to test it on chaos calmer and see. I think there's a difference in the lua bindings for libuci between these two versions.

Will let you know later today, sorry for the inconvenience!

Federico

[Federico Capoano]

This commit should fix it:

https://github.com/openwisp/openwisp-config/commit/cd47fb2cb94e9940c9dd416ef83f2483b0d37399

I have tested the changes on OpenWRT 15.05.01, but I'm waiting for the compilation to complete in order to reflash a router and try from a fresh install.

I tested the latest fix on a fresh router and everything is ok.

[Andrea Gabellini]

It also works well here! ;-)
