I'm trying to implement Link aggregation control protocols using Opendaylight controller by following this guide :
On mininet i already running the network topology, configuring the bonding.
On the opendaylight i already running karaf and several feature needed to implement LACP.
The problem is when i already reach this step,
dump-groups command
the dump-groups command doesnt recognized. Attached the the error announcement image.
dump-groups unknown command
I hope you can help me solve this problem guys.
Thank you very much.
Already solved, the problem arise because the openvswitch version in my mininet VM is the old version.
After upgrade the openvswitch became version 2.3.1 the problem solved.
Thanks all.

I am trying to build a simple app using spring boot and spring shell . My pom.xml is like this:
I am getting the below error when trying to connect to the shell using putty
I am not able to get any pointers.
Putty I downloaded for windows. Trying connecting using user as username, password shown in console, port 2000. Logs says authentication successful. Still a NullPointerException
I am using jdk 1.8 only. Not jre.
There are many open issues on this field right now. One of them is your same issue but specific for macOs, i do not have windows, but perhaps you can reproduce it same way and comment on that jira.
You can check it here:
https://jira.exoplatform.org/projects/CRASH/issues/CRASH-252?filter=allopenissues
If you want to use it, you should return to an older version better :)
Good luck!
I am using spring-boot and every time if i run my project again then it throws an error
Port already in use
So i have to stop java.exe from task manager everytime.
Is there any workaround for this?
I am already using dev tools in case somebody suggests that answer.
Thanks!!
Heyy, I'm looking for up-to-date kibana plug-in resources to help me learn and understand how to develop one.
All the resources I've found are out-of-date.
Can anyone help, please?
I suggest understanding plugin directory structure for traffic plugin which would be one of simplest plugin to understand and you could directly add it to your installed plugin folder in kibana and see it working.
Other than that I would also suggest you do read Tim Roes blogs for developing kibana plugins.
Last I would also suggest to use elasticsearch discussion forum for kibana related issues as well for quicker responses.
As kibana has different js files which loaded synchrnized way. you can use as it required.
I am trying to use the RStudio server installation that comes with H2O, following instructions for bringing it up on EC2 here. All of this completes successfully, and I get RStudio working on port 8787, however, I don't know what the default logon credentials are. Are there any? Will have to log into the EC2 instance and configure a user manually?
The documentation that you are referencing is actually for an older version of H2O. You can reference our new documentation here: http://h2o-release.s3.amazonaws.com/h2o/rel-simons/7/docs-website/h2o-docs/index.html#%E2%80%A6%20On%20EC2%20and%20S3
This should cover the questions that you have. If not, please let me know!
I installed sonar-3.7.2 without issue. I have it working properly with oracle. I can analyze maven-3 projects from a client machine on the same network as the sonarqube server.
The docs says it supports maven-3.x and maven-2.2.x. We are in the process of upgrading projects to maven-3 but many of our projects still use maven-2.0.9. I was hoping that the 2.2.x condition was merely due to what people were testing with and not a real limitation but some newly downloaded poms in my artifactory contain the property maven.min.version set to 2.2.1.
I need a version that will work with maven-2.0.9.
I saw a log from one of my coworkers also trying out sonar and it showed maven-2.0.9 was being used successfully. He is using defaults. I am setting up for production.
The error that I get (cleaned up of course):
Caused by: org.sonar.api.utils.HttpDownloader$HttpException: Fail to download [http://myhost:myport/batch_bootstrap/properties?project=mygroupid:myartifactid]. Response code: 400
I have tried sonar 3.7.2, 3.6.3 and 3.5.1 and get the same error in each case. In each case
analyzing a maven-3 project works (to prove everything else is ok)
I have tried adding the webcontext /sonar instead of just /.
I have tried setting the Server base url in the sonarqube server even though I have not tested anything yet related to sending emails.
I saw something about corruption in the local .m2 on another thread. Removing it did not help either.
Any and all suggestions appreciated.

I think the documentation is quite clear : http://docs.codehaus.org/display/SONAR/Installing+and+Configuring+Maven
SonarQube supports only Maven 2.2.x and 3.x
But my question is : What's the problem to upgrade from maven 2.0.9 to 2.2.x?
