Appeal on install Netopeer-GUI

[lilonghua2014]

I met a question,when I install Netopeer-GUI on ubuntu(12.04).As follow: checking for gcc... gcc checking whether the C compiler works... no configure: error: in /var/www/tmp/netopeer-gui/install/mod_netconf': configure: error: C compiler cannot create executables Seeconfig.log' for more details configure: error: ./configure failed for mod_netconf

Hello, I'll do my best to help you. What is the architecture of you system, x86_64? (try to execute uname -a) Do you have installed "build-essential" package? (apt-get install build-essential) It seems to me that configure could not find some libraries... Mod_netconf, which is being configured and compiled, is the backend of Netopeer-GUI web interface.

By default, it is compiled using Apache development tool apxs as a module for Apache and it is linked with libraries: libwebsockets, libjson, libnetconf, libxml2, libapr-1, libaprutil-1. Makefile also contains target for webgui_backend that is standalone executable. However, you should figure out the issue with failing configure at first... Tomas

[lilonghua2014]

thanks for your help. I have installed "build-essential" package. And the system information: Linux netopeer 3.8.0-29-generic #42~precise1-Ubuntu SMP Wed Aug 14 16:19:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux "it is compiled using Apache development tool apxs as a module for Apache ",How do I operate? I have linked the libraries to mod_netconf.Additionally,this issue is met when execute "./configure" in mod_netconf. thanks again!

[cejkato2]

Here is the story: at first, we have designed the backend of NetopeerGUI as a module for Apache web server. Note: we need to create persistent NETCONF sessions that would be accessible from various HTTP requests without need of NETCONF reconnection on every request. The module is called mod_netconf and it is automaticaly compiled and installed via make and make install.

As an alternative way to run the backend, Makefile contains the webgui_backend target that is also made by make. However it can be compiled manually and separately in case a user don't want to use Apache.

As the result, backend can be run either in Apache (module is installed and restart of Apache should be sufficient) or as a standalone binary (execute webgui_backend).

Both solutions act in similar way: they create unix socket in /var/run and listen for requests from PHP. In addition, backend opens TCP port 8080 that is used for asynchronous NETCONF notifications that can be delivered to the GUI via websocket.

I hope this kind of additional information will be useful for You...

You can try preinstalled demo virtual machine for VirtualBox that can be downloaded from http://www.liberouter.org/docs/2014-11-24-netopeer-demo.ova The machine contains netopeer-server with some transapi modules, netopeer-cli, Netopeer-GUI. If you had any feedback, please let us know... Tomas

[Premilav]

I have installed "http://www.liberouter.org/docs/2014-11-24-netopeer-demo.ova". I could like to add few modules. Request you to let me know the steps to add new module to the above netconf-server.

[michalvasko]

Hi,

you can easily add your transAPI modules using netopeer-manager.

Regards, Michal

[Premilav]

Hi Michal,

Thanks for the reply. I am using this "netopeergui", i am unable to execute any edit-config. Any help will be highly appreciated.

[alexadavid]

Hi, you can find basic informations in readme in virtual machine desktop.

... Problems with NETCONF tools: Try to look into log files: /var/log/messages (output from netopeer-server and netopeer-agent) /var/log/httpd/error_log (output from Netopeer-GUI backend) /var/www/netopeer-gui/app/logs/prod.* ...

But as I see now from discussion history, you have installed old demo version of virtual machine, please rather use one described here https://github.com/CESNET/Netopeer-GUI - it is last stable release of our demo.

[Premilav]

Hi,

I am trying to do "edit-config" on the device, below is the RPC stack. Request you to let me know what is wrong in this. It throws the error "There is no device/data that could be affected".

<?xml version="1.0" encoding="UTF-8" standalone="no"?><hello xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"><capabiliti
es><capability>urn:ietf:params:netconf:base:1.0</capability></capabilities></hello>

The CONFIG TREE isiis : system

The output isiis : clock

[cejkato2]

It seems to me that NETCONF messages were badly pasted in here... try to enclose your "code" into:

your XML samples

and use "Preview" please...

[Premilav]

Thanks for the info. I have added the module "toaster.yin" via "netopeergui-manager". The manager list shows the module is enabled. <module name="toaster" xmlns="urn:ietf:params:xml:ns:yang:yin:1"

<"yang-version value="1""> <"namespace uri="http://netconfcentral.org/ns/toaster""> <"prefix value="toast""> <"organisation"> <"text"> Netconf Central <"/text"> <"/organization"> This is the yin file i have added to "netopeergui" virtual box.Now when i do "get-config" with my own api it shows other default modules and not the module which i have added. Please let me know what should i do, to get this data. Used netopeer-configurator, the UI says module is enabled.

[rkrejci]

Hi, did you upgraded the VM demo as suggested @alexadavid?

Can you provide the list of capabilities announced by the server? It is available in the GUI when you connect to a device and then on the "Configuration" screen there is Info icon on the left side of the upper bar (next to the lock icon). So just click on the icon and post the content.

[Premilav]

I have installed the latest one https://www.liberouter.org/docs/2015-05-11-netopeer-demo.ova as instructed.

Now restarted the server in virtual box via UI-> popup->restart. NetopeerGui server is not getting initialized. Please let me know what might be the problem. I am in need of Netconf server for testing all the netconf operations.

[Premilav]

While connect the server via netconf cli it says error : libnetconf error:Unable to connect to localhost:830 connect:connecting to the localhost:830 as user"(null)" failed. Help is highly appreciated.

[rkrejci]

Does the netopeer-server provide some log messages? Try to start the server manually with a higher verbose level and check (post) the output:

# netopeer-server -v 3

[Premilav]

Thanks for response. I removed few newly added modules via netopeer-manager. When i restarted the server, itis getting started is listed below, Now i would like to add one module and do get-config & edit-config. Any small sample module for testing.

Hi,

Could anyone tell me how the edit-config will be carried out for groups.

[alexadavid]

Hello, what do you exactly mean carried out for groups? Do you mean groups in linux module (called system in demo)? Or for more devices (group of devices)?

[Premilav]

Hi, "Grouping in Netconf" Eg : https://www.ietf.org/mail-archive/web/netconf/current/msg10318.html Few yang files have a set of groups named as "Grouping" http://dld.netconfcentral.org/src/ietf-ipfix-psamp@2012-09-05.yang How this is handled in netopeerGui server.

[michalvasko]

Hi,

groupings are basically just a syntactic construct, they are not handled specially. They get placed wherever uses with the name of the grouping occurs in the model to create the final model that is afterwards used in NetopeerGUI. You can see how the final model looks using, for instance, pyang -f tree path-to-the-model-file.

Regards, Michal

[Premilav]

Hi, When i did "edit-config" to netopeer, it says "ok" message.But the value is not added/modified in the server. What would be the problem.

[rkrejci]

The problem could be in your edit-config. It is impossible to say what should happen when we don't see the edit-config content and the content of the datastore being targeted.

BTW, please note the name of this issue - "Appeal on install Netopeer-GUI" I guess that this has nothing to do with install process, so please open a new issue and be more specific in what you are doing, what is expected result and what is, in contrast, the real result.
