Summary0000346: easycwmp client stuck and not making connection with ACS server
DescriptionHi,

I have cross compiled easycwmp client and all dependencies for
arm-cortexa9-linux-gbueabi. I've followed instruction given here
http://www.easycwmp.org/install.html# [^] for EasyCwmp install for
other Linux distributions.

I have copied required libraries / binaries etc to hardware box
and started genieacs and easycemp client. The easycwmp client got
stuck and logs on the screen as below.

root@phyFLEX-i:~ /usr/sbin/easycwmpd -f -b

2018-07-19 06:54:13 [easycwmp] NOTICE - external script exit

After seeing the code it seems the client (easycwmpd) is waiting for
easycwmp --json-input to exit and but it is not and as a result it is in infinite loop

root@phyFLEX-i:~ ps -aef | grep easycwmp
root 4288 4130 0 06:54 pts/4 00:00:00 /usr/sbin/easycwmpd -f -b
root 4289 4288 0 06:54 pts/4 00:00:00 /bin/sh /usr/sbin/easycwmp --json-input
root 4302 4297 0 06:55 pts/6 00:00:00 grep easycwmp

Also some information as below based on similar issue in easycwmp support site

root@phyFLEX-i:~ easycwmp --json-input
easycwmp>
{"command": "inform", "class": "device_id"}
easycwmp> (<--------blank no output here)



root@phyFLEX-i:~ easycwmp --json-input
easycwmp>
{"command": "get", "class": "value"}
easycwmp> (<--------blank no output here)

Please suggest what I'm missing it to make client communicate with server

Also one information that on my box for dependencies (curl, json-c, libubox, ubus, uci, microxml) the make install is not executed as compilation is done on virtual machine with required toolchain so I copied required libraries and binararies and created softlinks as suggested to install webpage

Please provide valuable feedback / pointer to proceed further.

Thanks,

you have some issue in json package. may be there is some scripts from json package are not installed.

To guaranty that your easycwmp is well installed, you should got output of the following command:

Linux$ easycwmp inform
{ "parameter": "Device.DeviceInfo.SpecVersion", "value": "1.0" }
{ "parameter": "Device.DeviceInfo.ProvisioningCode", "value": "" }
{ "parameter": "Device.DeviceInfo.Manufacturer", "value": "" }
{ "parameter": "Device.DeviceInfo.ManufacturerOUI", "value": "" }
{ "parameter": "Device.DeviceInfo.ProductClass", "value": "" }
{ "parameter": "Device.DeviceInfo.SerialNumber", "value": "" }
{ "parameter": "Device.DeviceInfo.HardwareVersion", "value": "" }
{ "parameter": "Device.DeviceInfo.SoftwareVersion", "value": "" }
{ "parameter": "Device.ManagementServer.ConnectionRequestURL", "value": "" }
{ "parameter": "Device.ManagementServer.ParameterKey", "value": "" }

Hi,

Thanks for your response.

On the box, I am able to get following output for the command you suggested to execute.

phyFLEX-i.MX6 login: root
root@phyFLEX-i:~ easycwmp inform
{ "parameter": "Device.DeviceInfo.SpecVersion", "value": "1.0" }
{ "parameter": "Device.DeviceInfo.ProvisioningCode", "value": "" }
{ "parameter": "Device.DeviceInfo.Manufacturer", "value": "easycwmp" }
{ "parameter": "Device.DeviceInfo.ManufacturerOUI", "value": "FFFFFF" }
{ "parameter": "Device.DeviceInfo.ProductClass", "value": "easycwmp" }
{ "parameter": "Device.DeviceInfo.SerialNumber", "value": "FFFFFF123456" }
{ "parameter": "Device.DeviceInfo.HardwareVersion", "value": "example_hw_version" }
{ "parameter": "Device.DeviceInfo.SoftwareVersion", "value": "example_sw_version" }

{ "parameter": "Device.ManagementServer.ParameterKey", "value": "" }

and there is no connection b/w client and server. Please provide your valuable feedback / pointer

Try now the following command

Linux$ easycwmp --json-input

And then input the following json message:

easycwmp>
{"command": "inform"}

you should got the same output you did with "easycwmp inform"

root@phyFLEX-i:~ easycwmp --json-input
easycwmp>
{"command": "inform"}
easycwmp>

Please advice

You have some issue with your json installation on your linux
The json.sh (from json-c package) seems does not work properly on your linux platform for some reasons.
you have to check that

Hi,

Since I copied executable and library manually so there was issue with default PATH variable. When I edited it for correct path(s) the tr069 client is able to make connection with genieacs ACS server

HTTP inform sent by client is responded back by server but in keep alive mode when client is trying to send empty http request it results into
* The requested URL returned error: 400

For more detail refer below and let me know any pointer to debug this further.

Hi,

Let me know some pointer to debug this further as I am not able to understand that why client is not able to send empty http request when he just sent one http request as part of Inform so communication is through b/w client and server.

Also I see on successful case (simulated client and server on x86 platform) the logs in geniacs as below. Difference I see in content of InformEvent being

"1 BOOT,2 PERIODIC" - in Success case and "0 BOOTSTRAP,1 BOOT" as in failure case. I hope this is okay?

Success case (client & server on x86 platform)
----------------------------------------------

2018-08-10T05:36:55.194Z [INFO] 192.168.0.211 FFFFFF-easycwmp-FFFFFF123456: Inform; cpeRequestId="1" informEvent="1 BOOT,2 PERIODIC" informRetryCount=0
2018-08-10T05:38:13.019Z [INFO] 192.168.0.211 FFFFFF-easycwmp-FFFFFF123456: Inform; cpeRequestId="2" informEvent="2 PERIODIC" informRetryCount=0

whereas for unsuccessful case (client on ARM based platform)
-------------------------------------------------------------

2018-08-10T05:46:51.750Z [INFO] 192.168.0.200 FFFFFF-easycwmp-FFFFFF123456: Inform; cpeRequestId="1" informEvent="0 BOOTSTRAP,1 BOOT" informRetryCount=0
2018-08-10T05:46:51.765Z [ERROR] 192.168.0.200 FFFFFF-easycwmp-FFFFFF123456: Invalid session
2018-08-10T05:46:59.202Z [INFO] 192.168.0.200 FFFFFF-easycwmp-FFFFFF123456: Inform; cpeRequestId="2" informEvent="" informRetryCount=1
2018-08-10T05:46:59.213Z [ERROR] 192.168.0.200 FFFFFF-easycwmp-FFFFFF123456: Invalid session

One more difference I see on easycwmp client log for success case is the comment starting with "* Found...."

Success case
------------

+++ SEND EMPTY HTTP REQUEST +++
* Found bundle for host 192.168.0.211: 0x5590c1226020 [can pipeline]
* Re-using existing connection! (#0) with host 192.168.0.211
* Connected to 192.168.0.211 (192.168.0.211) port 7547 (#0)
> POST / HTTP/1.1

and this is not the case in failure case

Failure case
-------------

+++ SEND EMPTY HTTP REQUEST +++
> POST / HTTP/1.1
Host: 192.168.0.210:7547
User-Agent: easycwmp
