I am following this tutorial: https://wiki.opendaylight.org/view/Getting_started
I am trying to use the following code in opendaylight using karaf
ovs-vsctl show
But the command window says Command not found: ovs-vsctl
I have installed all the necessary libraries and the local host server (http://localhost:8181/dlux/index.html) is running fine. But somehow odl can't find ovs.
Can anyone tell me what's the error? I am running win 8.
Thank you
You need to run this command outside of karaf terminal.
Firstly, you should have ovs(Open Virtual Switch) or Mininet installed, and then create one or two open switches.
Basically, you started the SDN controller in karaf, and now in the step you are encountering problem, the switches need to be assigned ODL controller as their manager.
You must check also that ovsdb is already installed in karaf.
For that, try to execute the next command:
feature:list | grep ovsdb
That command will display all the ovsdb components/features that are available in your karaf distribution. The third column will indicate you if a given component is already installed or not (if you see an X, that means that the component is installed). If you want to install a component/feature:
feature:install <name_of_the_feature>
After that, try to execute it outside of karaf, as Sidhant01 has indicated you before.
Try to do it with sudo:
sudo ovs-vsctl show.
If you want to configure ovsdb in an active mode:
tools-vm:~$ sudo ovs-vsctl set-manager tcp:127.0.0.1:6640
tools-vm:~$ sudo ovs-vsctl show
98d8cf7a-44b1-4b02-a60c-7d832409d06f
Manager "tcp:127.0.0.1:6640"
is_connected: true
ovs_version: "2.0.2"

Can I get a tip for installing on rasp buster? Im hung up on the install directions to check the status of the rabbitMQ server. Traceback of bash console:
(volttron) pi#raspberry:~/Desktop/volttron $ echo 'export RABBITMQ_HOME=$HOME/rabbitmq_server/rabbitmq_server-3.7.7'|sudo tee --append ~/.bashrc
export RABBITMQ_HOME=$HOME/rabbitmq_server/rabbitmq_server-3.7.7
(volttron) pi#raspberry:~/Desktop/volttron $ source ~/.bashrc
pi#raspberry:~/Desktop/volttron $ RABBITMQ_HOME/sbin/rabbitmqctl status
bash: RABBITMQ_HOME/sbin/rabbitmqctl: No such file or directory
There are a few tracebacks earlier on the installation...
If it makes a difference or not here is the entire bash console process. The git gist link I just created the name install.py even though its just bash commands copied pasted per install directions...
`pi#raspberry:~/Desktop $ git clone https://github.com/VOLTTRON/volttron --branch releases/7.x`
It looks like there are a couple of different issues going on here:
The issue you quote above (RABBITMQ_HOME/sbin/rabbitmqctl: No such file or directory) is that your shell isn't finding the rabbitmqctl command. It looks like you added the RABBITMQ_HOME environment variable to your .bashrc, but used the string RABBITMQ_HOME instead of the variable expansion $RABBITMQ_HOME when you tried to run the command. Try running it as $RABBITMQ_HOME/sbin/rabbitmqctl status instead.
The rabbitmqctl status command will check the status of the rabbitmq application, but I don't think you've done anything to start it yet (that happens when you bootstrap the platform and/or start the platform configured to use the RMQ broker)
I think that the traces earlier in the installation process are problematic (appears to be the same error hit two different ways), but you just haven't run into them yet. I haven't seen any issues building gevent on the RPi 4 with buster (though it is pretty slow), but the ctypes error makes me wonder if there's an issue with the underlying c library it is trying to build on top of. I did notice that you're getting amd64 erlang packages, are you running Raspbian on an x86 processor? (if so this isn't a permutation we've tried and you may be hitting some package compatibility edge case we haven't seen)
One thing to try is to manually install cython into your virtualenvironment and then try running the bootstrap script again with the virtualenvironment activated. You could also try and pip install gevent==20.6.1 directly in that virtualenvironment (this is what the bootstrap script was doing at the failure point). VOLTTRON depends on gevent, so if that isn't installing the platform won't be able to run.
I tried to import the biopython package in Spyder and got the error message:
ModuleNotFoundError: No module named 'biopython'
although biopython is installed.
I also checked the PYTHONPATH: there is a path set into the directory where the packages are stored.
Can somebody help? Did I miss something? Thanks for your help!
If you're using Anaconda, it's best to install all the packages you want from Anaconda if possible. You can check if a package is available with (e.g.):
conda search biopython
When I try that command it shows that biopython is available, so assuming you have access to the standard conda channels you should be able to get it this way.
Assuming you haven't already created a conda environment to work with, start by creating a new one with the packages you want to use:
conda create -n myenvname spyder biopython
where myenvname is the name you want to give the environment - call it whatever you like. If you want to use other packages as well, add their names to the end of this command. Then once the env is completed, activate it:
activate myenvname
or if this doesn't work, on Mac or Linux:
source activate myenvname
and start Spyder in this environment:
spyder
Each time you want to use this environment in future you will need to activate it first. You may also be able to do some of these tasks through the Anaconda Navigator or via Start menu shortcuts but the command line version will always work.
If there's a package you want that isn't available from conda but is available via pip, just use the pip command after creating and activating the environment.
If you are using Anaconda, a solution could be
conda install -c main biopython
following https://anaconda.org/main/biopython.
The official repository page helped me when I got your error message because numpy was not in place.
I am not able to install the package odl-dlux-all on the Ubuntu 16.04 machine. Following is the error message
Error executing command: Can't install feature odl-dlux-all/0.0.0:
null
VM : Ubuntu 16.04
Opendaylight version : Carbon
What is the issue?
Should i install gnome-desktop for this?
Prat,
This is what I have found. It looks like you and I were in the same boat. I ran into this issue, also. After additional searching, I found that ODL's website has a guide for the DLUX features.
These are the features I installed and it got me where I needed:
odl-dlux-core
odl-dluxapps-nodes
odl-dluxapps-topology
odl-dluxapps-yangui
odl-dluxapps-yangvisualizer
odl-dluxapps-yangman
Be sure you enter them as separate commands using the feature:install command prior to each of them.
I found the guide on ODL's website HERE.
I hope this helps!! :)
The way OpenDaylight's DLUX features are structured was changed in Carbon. Application-specific logic was broken out into odl-dluxapps-* Karaf features for easier maintenance.
Install and start OpenDaylight:
sudo dnf install -y http://cbs.centos.org/repos/nfv7-opendaylight-70-release/x86_64/os/Packages/opendaylight-7.0.0-1.el7.noarch.rpm
sudo systemctl start opendaylight
Connect to the Karaf shell (make take a moment for Karaf's SSH server to come up):
ssh -p 8101 karaf#localhost
# password: karaf
See the available DLUX features:
opendaylight-user#root>feature:list | grep dluxapps
odl-dluxapps-yangutils
odl-dluxapps-yangui
odl-dluxapps-topology
odl-dluxapps-yangvisualizer
odl-dluxapps-applications
odl-dluxapps-yangman
odl-dluxapps-nodes
features-dluxapps
Install the ones you're interested in:
opendaylight-user#root>feature:install odl-dluxapps-topology
In a browser on the same machine:
http://localhost:8181/index.html#/yangui/index
Login with admin/admin and things should work.
Here are the DLUX docs.
Note that DLUX isn't widely used by ODL developers, and isn't packaged as a product by vendors. Most people use the REST API directly to query OpenDaylight. There are REST API examples in the NetVirt Postman Collection, as an example.
It is true. You have to install all dlux features manually.
The Change against ODL Boron is, that Carbon removed feature odl-dlux-all. And in Carbon odl-dlux-core installs only core and nothing more. I had always gray login page in DLUX WEB login, there was nothing, only blank gray page.
I suggest you to use command: feature:list | grep dlux
This will create for you complete list of available DLUX features. And You have to install all of them.
After you finish installation of DLUX use same command with parameter -i which will show you only succesfully installed features:
feature:list -i | grep dlux
so you will see the result.
Don't forget that after instalation Dlux needs a few minutes to be fully ready. If you try to login to dlux during this time, you can get ERROR403 but also login page will not accept the credentials even they are correct. So be patient and wait.

DOCUMENTATION OF OPENDAYLIGHT
IS HORIBBLE AND SOMETIMES PURELY WRONG

I'm currently in the process of setting up my workspace on my company machine and have chosen Atom as my text editor of choice. The computer is not connected to the internet, so I will have to "manually" install packages. I've been having difficulties installing packages via usb transfer. I've copied and extracted packages to my ~/.atom/packages
The package I'm attempting to use (atom-beautify) shows up on the packages tab on the top of the editor. It also shows up under [Settings] -> [Packages].
When attempting to use the beautify I get the error message "Failed to activate the atom-beautify package" ... Cannot find module 'event-kit'
Also using Windows 10. Any help is greatly appreciated!
You can solve your problem. There are some way to solve your problem.I did not used win10, I am on win7.Yet you can try.
Paste atom-beautify to C:\Users\User.atom\packages and change pacakage.json
atom-beautify needs a dependency named bluebird, if you can try to add this to atom.
It step 1 or step 2 failed then goes to step 2,
Connecting your pc to internet run this command from your terminal: apm install atom-beautify
Source: https://github.com/Glavin001/atom-beautify/issues/879#issuecomment-218753674
Safest bet with installing atom packages offline is to install it on another online PC and then copy all contents from your packages location to offline PC.
i'm trying z.load in apache zeppelin as following:
%dep
z.load("/zeppelin-0.5.6-incubating-bin-all/lplibs/hive/csv-serde-1.0.5-jar-with-dependencies.jar")
I get an ERROR and it says (not sure this is the error):
Must be used before SparkInterpreter (%spark) initialized
Hint: put this paragraph before any Spark code and restart Zeppelin/Interpreter
this zeppelin section is the first i have in my notebook so i'm not sure what its complaining about..
Right now I can't check your problem, but you should restart interpreter (pushing restart button) before loading dependency jar file.
There might be a chance that Sparkcontext has already been started by other notebook.
So as Kangrok mentioned, just restart Spark interpreter.
But apart from that, why don't you use the latest zeppelin, in which you don't need to use %dep to load your dependencies. Instead it can load from Interpreter screen.
More details can be found here https://zeppelin.incubator.apache.org/docs/0.6.0-incubating-SNAPSHOT/manual/dependencymanagement.html
