Installing FreePBX as a Virtual machine - openstack

I have been trying to launch FreePBX as a VM on Openstack. The launching is successful. but the during the installation time I get the following error:Some first boot error occured and the system is not properly setup. Check to see if you have internet access and re-run /etc/pbx_first_boot.sh.!! any suggestions?

I haven't a solution for your problem, but as a contribution to this community I can tell my FreePBX runs smoothly since 5 years as a Virtual Machine on VMWare ESXi (hosted on a local physical server Dell PowerEdge 1950) managing 100 extensions and up to 15 concurrent external channels.

Abhishek, are you using centos or ubuntu. Try to install "PBX in a Flesh" great product and have FreePBX stable and bugfree.

How to tell the network usage in linux without installing any new tool?

I am doing a load test on a Unix machine and I want to see if my machine's configuration is limiting the number of requests I can make at a time.
I can find memory and CPU usage easily.
How do I find out the network usage without installing any new tool like iftop?
I do not have the ability to install new applications on the Unix machine.
I am using the following Linux version:-
Red Hat Enterprise Linux Server release 7.5 (Maipo)

OpenStack upgrade with minimal downtime with 2 nodes

I'm looking for a solution on how to upgrade 2 OpenStack nodes with minimal downtime of running virtual machines.
Our current situation is that we have one node working as controller with about 50 live virtual machines running on it.
We have second server with the same HW specification as the one with running OpenStack (Same blade in blade cluster). This used to be a VMware server but last year we continously migrated all virtual machines to OpenStack.
We can install the second node to be either controller or compute node.
My research is focused on what's the best way to upgrade to higher version with minimal downtime of live virtual machines.
Any suggestions please? Thank you.
You should have no downtime on your Virtual Machines when upgrading OpenStack. The OpenStack services can be restarted at anytime and should only affect API requests. The only potential impact on running virtual machines would be if you need to update something like OVS or the Operating System (includes things like kvm).

Windows Client For Cloudera Hadoop Cluster

I am trying to find out if I can use Windows Client machines for commissioning jobs running on a Linux Cloudera Cluster.
I currently use Linux clients and would like to run tasks such as spark-submit test.jar which runs a spark job on the cluster and replicate this behavior on windows clients.
If yes, any information about how you can go about doing this would be greatly appreciated?
You can very well use VM linux image installed on windows and access Hadoop cluster deployed on Linux.
You can also use cygwin otherwise.

Meteor Vagrant can curl localhost:3000 but windows cannot open localhost:3000 windows 8.1

Good morning,
Working on installing Meteor on windows using the following guide:https://gist.github.com/gabrielhpugliese/5855677
As pointed out on other posts its a little dated and I needed to install meteor separately, which I used this guide: Unable to install meteorite on Ubuntu VM
Currently, my set up can do the following:
files stay in sync between vagrant and windows
localhost:3000/ is working on the server
What I still need help completing:
when opening localhost:3000/ in my windows browser, I get the "This webpage is not available
I know that the vagrant VM is correctly serving the app because I opened a new instance of vagrant and curled the localhoust:3000/
I am actively working in django and node and can successfully run apps locally on :8000 and :8080, I tested the meteor app on those ports but still couldn't connect. I also created a windows firewall port exception on 3000 but the results didn't change.
I know that there is a windows-preview currently out, but that is not working for me and I have an issue being tracked in gitHub.
Thank you in advance.
One thing that might be worth mentioning is it is somewhat possible to use Meteor on windows.
More details here: https://github.com/meteor/meteor/wiki/Preview-of-Meteor-on-Windows.
With your vagrant machine it sounds like there is a problem with port forwarding on your localhost machine to the VM's ports.
One possible simple way to get passed this is to get your Ubuntu machines IP address and simply load it up using http://<ip address>:3000.
I'm not sure why the port forwarding isn't working on your machine. In general the reason is provided when you run vagrant up, if there was an issue.

Can RStudio (IDE NOT server) be configured to use remote R setup?

I am transitioning my debian setup into one where all debian-repository external apps run in dedicated docker containers.
In this context rstudio, of which I am a heavy user, has me puzzled ... does anybody have insight into whether it's possible to run it as a client to remote R installation?
What is a very cool feature of RStudio is RStudio Server. You install RStudio Server on you Ubuntu server and log in to a specific port where RStudio Server is running. You then get your full RStudio interface in your web browser. This allows you to run all your R analyses from any computer that has a modern browser and an internet connection.
R then runs on the remote server, asking almost no resource from the computer you are connecting from.
