I thought that this could be caused because of the version of libnetconf, so I checked out the branch 0.9.x of libnetconf and installed everything again. But when I tried to install the ofc-server (make), I got a more weird error:

And to recover from this last error I had to reset the whole installation because when I compile and install again the master branch, running the ofc-server deploys this weird error:

Please, some help.

When i install the of-config, i run the comman:
./configure --with-ovs-srcdir=/root/openvswitch-2.3.1 PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
Then i had get the error result:
configure: error: libopenvswitch.a was not found. Try --with-ovs-libpath
But i use this command to find the libopenvswitch.a file:
sudo find / -iname libopenvswitch.a -type f
And i had serch the file:
/lib/libopenvswitch.a
/usr/local/lib/libopenvswitch.a
/home/mx/ovs/lib/.libs/libopenvswitch.a
Please help me to solve this problem , thanks!

I attempted to spin up a Vagrant VM, but it looks like libnetconf is failing during the configure step, with the following:
configure: error: Missing libssh <>=0.6.4

I'm assuming something similar to this may be required.

I had a crack at it, but it looks like the libssh server is currently out of action - 404 on the tarball.

For easier user setup and access to OF-Config, I suggest setting up a vagrant build containing all requirements for OFC Server and its components running on it.

In addition, a docker container hosted in docker repo with ofc-server will make life easier for anyone trying to replicate ofc-server setup and directly go on to use the server to play with netconf

I am happy to work on a Dockerfile and Vagrantfile with usage instructions (if that helps)

Thanks,
Sriram

This project appears to be unmaintained. The last commit was in 2015. Is it time to withdraw the project?

As mentioned in #3 (comment), this project implements OF-CONFIG 1.2.

I think, that it would be useful to explicitly specify OF-Config version in requests and answers.
For example,

<capable-switch xmlns="urn:onf:config:yang"> => <capable-switch xmlns="urn:onf:of12:config:yang">

Hi,
Newbie question..Any help is appreciated

I managed to get the ofc-server running, but wasn't sure on the following:
QN1: netopeer installation requirements
QN2: ofc-server connection to ofc-bridge
QN3: required steps to start all needed daemons and clients:

QN1: Netopeer Installation:
Do I have to install the netopeer/server as well or will netopeer-cli suffice? my initial understanding from README was, netopeer is only used for cli and it will talk to libnetconf (which will run the netconf server)?
++ If yes, can you tell me the setup for libnetconf and how to start the netconf server and how to connect from netopeer-cli?
++ If no, can you please clarify on the netopeer & netconf server setup?

QN2: I wasn't entirely sure on the correct order to start all daemons. Currently my ofc-server is running and is connected to OVSDB, but I get an error on the connection to ofc-bridge. My ovs is installed correctly and I am able to see a default bridge named 'ofc-bridge' is added. Then, when I start ofc-server -v 3 -f , i get the following:

The log indicates that the ofc-server is connected to the ovsdb, but it is unable to talk to ofc-bridge. Any conf required in ovs to make ofc-bridge listen to of-config calls?

QN3: Steps to start all daemons and issue commands:
++ Run OVS (which starts ovsdb internall and configures ofc-bridge)
++ Run ofc-server with ofc-server -v 3 -f
++ Start netconf server via libnetconf?? Not sure.. Or start the netopeer/server??
++ Setup netopeer cli and connect to the netconf server
++ Write XML files (currently use the netconf-tests folder samples) to issue commands..

Is this correct?

Thanks,
Sriram

Hi all,
I installed of-config for working with mininet emulated network. Everything works correct, ofc-server collect data about nodes running in mininet, but what I have to do is to use another YANG data model (I have to use te-topology in my project). Is there any possibility to change model used by server?

I would be grateful for any advices,
Regards,
Ola

Hi,

I was was looking at the OF-config spec as well as the openvswitch commands. I am not clear about whether this of-config implementation supports the ovs-ofctl commands especially those related to creation of flow entries like
ovs-ofctl add-flow br0 priority=200,in_port=1,actions=output:2

I don't see an example of this in the netconf-tests. If there is any other user documentation/ examples that can help me with this let me know.

I understand this is not an issue. But I could not find any other forum for this.

Thanks,
Abhijeet

I would like to use OF-Config . Is there any kind of library I can use too write a client for your Server ?

Hi,
I want to modify this project without OVSDB. Because I am running OpenFlow switch. I will change OVSDB function to OpenFlow function.
Will be the matter concrete and feasible?
Besides, Can I use netopeer-server to install of-config module?

Thanks,
Jack

I expect to get more information about my-br tunnel: type, local-endpoint-address, remote-endpoint-address, as mentioned in of-config 1.2 spec...

What I am doing wrong?

There is an error when I use netopeer-cli connecting to ofc-server,as I have started the ofc-server using the conmand "ofc-server -v 3 -f",and the ofc-server starts successfully.

The error shows below：
root@ubuntu:~# netopeer-cli
netconf> connect --port 830 --login root localhost
libnetconf ERROR: Starting the SSH session failed (Socket error: disconnected)
connect: connecting to the localhost:830 as user "root" failed.

How shoul I solve this problem?

Hi,
I have a question about datastore.
When copy running config to startup config, the startup.xml file has modified ??

Thanks,

I see the following issue when generating configure file. RHEL 6.5. Can these be ignored?

autoconf configure.ac > configure

I try to run ofc-server on OpenStack compute node with OVS networking.
I successfully compiled ofc-server, pointed it to downloaded openvswitch 2.1.3 sources, as specified in installation manual.
Then I installed openvswitch 2.1.3 package from ubuntu 14.10 repository.
When I try to start ofc-server:

I get these messages:

Hi,

is there any other documentation about the API? I found some code mentioning dbus. What is this about? Can this dbus interface be used by some client? Is there any documentation for this I can pass on? Or is there some other api to access openvswitch programmatically via C or dbus?

-> Over at http://lists.freedesktop.org/archives/systemd-devel/ I asked for support of openvswitch in systemd-nspawn.

Thanks a lot.

Hello!
I'm trying to setup configuration of openvswitch with Ryu of_config library:

from ryu.base import app_manager
from ryu.lib import hub
from ryu.lib.of_config import capable_switch

HOST = '127.0.0.1'
PORT = 830
USERNAME = 'of-config'
PASSWORD = 'password'

class OFConfigClient(app_manager.RyuApp):
        def __init__(self, *args, **kwargs):
                super(OFConfigClient, self).__init__(*args, **kwargs)
                self.switch = capable_switch.OFCapableSwitch(
                        host=HOST, port=PORT, username=USERNAME, password=PASSWORD,
                        unknown_host_cb=lambda host, fingerprint: True)

        def get_set(self):
                csw = self.switch.get_config('running')
                self.switch.edit_config('running', csw)

if __name__ == '__main__':
        client = OFConfigClient()
        client.get_set()

This script get configuration from OVS by using of-config and set it back in unchanged state.
When I run it, I get this traceback:

Traceback (most recent call last):
  File "test_ovs_ofconfig.py", line 23, in <module>
    client.get_set()

Simple reading of configuration works just fine.

Hi,
I can get/edit config using ofcds_getconfig and ofcds_editconfig.
netopeer-cli: get-config --filter=ovs.xml running
edit-config --config=create_switch.xml running

How to get status data using ofc_get_state_data??

Thanks

Hi,
Who is know about OF-CONFIG 1.2 spec OpenFlow Port?
I cannot found requested-number leaf on OF-CONFIG 1.2 spec.
I found resource-id leaf on OF-CONFIG 1.2 spec.

In of-config.yang file:
leaf requested-number {
type uint64 {
range "1..65279";
}
description
"This is the requested OpenFlow Port number for this interface. The switch
is expected to try and use the value of this lead as the port number for
the interface. If the switch is unable to use the requested value or if
this leaf is not present, it will choose a free port to use.";
}

Hi,

Similar to OVS installation, we might require Installation guide for different distros (if you believe there are unique differences for each distro)

Kindly check OVS https://github.com/openvswitch/ovs

I am happy to open a Pull Request once I get this installation successful in my distro.

@rananth Let me know.

Thanks,
Sriram

For starters like me, I found the netconf-tests scripts to be very useful. However, I have previously worked on OpenFlow and hence it was easy for me to figure out which files to try out.

A tutorial file with instruction to execute simple netconf scripts and the order in which they should be executed will help users big time, example like this https://github.com/openvswitch/ovs/blob/master/tutorial/Tutorial.md

I believe the README file here https://github.com/openvswitch/of-config/tree/master/netconf-tests has that information. But some additional explanation on the usage will help.

Thanks,
Sriram

Hello!
Working with ofc-server, I found that ofc-server crashes without any messages, if I try to create logical switch without datapath-id.
Unfortunately, there is no XML schemas in of-config 1.2 specification, but as mentioned in of-config 1.1.1 spec (p. 27),

This element MUST be present in the NETCONF data store.
If this element is not present in a NETCONF
operation 'create', 'merge' or 'replace' and the parent
element does not exist, a 'data-missing' error is returned.

Steps to reproduce:
create_switch.xml

<capable-switch xmlns="urn:onf:config:yang" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">
    <id>openvswitch</id>
    <logical-switches>
      <switch nc:operation="create">
        <id>test-bridge</id>
      </switch>
    </logical-switches>
</capable-switch>

and do edit-config with, for example, netopeer-cli.

Hi,

I am trying to setup this installation in my Ubuntu machine, but I am facing some issues:
My setup:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty
kernel version: 3.13.0-39-generic

Here are the steps that I followed:

OF-CONFIG Build Requirements

For the list of OF-CONFIG dependencies, I installed the following:
++ apt-get install autoconf automate gcc libtool python-libxml2 libxml2-dev m4 make openssl libssl-dev pkg-config

For OF-CONFIG dependencies, I installed:
++ apt-get install dbus-*dev

I then downloaded the below packages:
++ openvswitch-2.3.1 and pyang-1.4.1

To stick to the INSTALL guide, I downloaded all packages in /root/

For Open vSwitch and libnetconf dependencies, I installed the following:
++ apt-get install libxslt-dev libssh2.1-dev libcurl4-openssl-dev xsltproc

Open vSwitch Installation:

I did the untar and configuration as specified in INSTALL, but I wasn't sure if I need a symlink specification (ln -s /usr/src/kernels/2.6.32-504.8.1.el6.x86_64/ /lib/modules/2.6.32-504.el6.x86_64/build)

I started the ovs-ctl with system-id specification as:
++ /usr/local/share/openvswitch/scripts/ovs-ctl --system-id=random start

OF-CONFIG Installation
pyang: works fine, but
libnetconf installation issues: The default libxml2 installation in ubuntu will not be picked up by lnctool, so I installed "apt-get python-libxml2"

OF-CONFIG configuration steps: After building, installation and configuration, I tried to start ofc-server which throws the following error:

ofc-server[26599]: D-Bus name error (Connection ":1.7" is not allowed to own the service "org.opennetworking.ofc.server" due to security policies in the configuration file)
ofc-server[26599]: Unable to became primary owner of the "org.opennetworking.ofc.server" bus.
ofc-server[26599]: Communication subsystem not initiated.

Kindly let me know what I am missing here.

Hello!

I have found, that ofc-server does not provide datapath-id values of manually created bridges:

# ovs-vsctl show
  860c153c-ae27-46f8-9695-bd7c28a5beb1
    Bridge ofc-bridge
        fail_mode: secure
        Port ofc-bridge
            Interface ofc-bridge
                type: system
# ovs-vsctl get Bridge ofc-bridge datapath-id
  "0001020304050607"
# ovs-vsctl get Bridge ofc-bridge other_config:datapath-id
  "0001020304050607"

# ovs-vsctl add-br my-br
# ovs-vsctl get Bridge my-br datapath-id
  "00008ad8fa615a4f"
# ovs-vsctl get Bridge my-br other_config:datapath-id
  ovs-vsctl: no key "datapath-id" in Bridge record "my-br" column other_config

$ netopeer-cli
netconf> connect --login $USER localhost
netconf> get-config running
  Result:
<capable-switch xmlns="urn:onf:config:yang">

        <lost-connection-behavior>failSecureMode</lost-connection-behavior>
        <resources>
          <port>ofc-bridge</port>
        </resources>
      </switch>
    </logical-switches>
  </capable-switch>

So, datapath-id of my-br is not listed in answer from ofc-server.
This behaviour is too unhandy, if I try to make edit-config:

Datastore fails to validate (Element capable-switch failed to validate content)
