I wish to create a private cloud using openstack for our college (which has to be hosted in our college) which will be mostly used for file sharing purpose (right now we have this as one of the priority) so that students can access the files hosted on it from their home.
Right now I have installed openstack's latest version in my local ubuntu machine (All in one machine)using devstack for the testing purpose, it's working fine. Now I am planning to install multi node open stack with help of my friend's laptops (3-4 laptops) to host files which can be accessed through FTP or HTTP. Once configured with local machines we will replicate the same in our college environment. At this moment I am not able to understand what all components are required to be installed and what should be the openstack structure to achieve our requirement.
Please let me know how should I proceed for the same.

I’m an absolute beginner when it comes to setting up a Jenkins environment but I have just installed Jenkins on a MAC v10.15.5 using home-brew and would like the capability to:
Open a web browser
Login to Jenkins from any machine on any network
Trigger a job.
I’m able to do this using a different machine on the same network but unable to do this using a machine on a different network. I changed the "httpListenAddress" value within the jenkins-lts.plist file to 0.0.0.0 to allow the web interface to be accessible from anywhere as mentioned at https://www.macminivault.com/installing-jenkins-on-macos/ but apart from that I’m not sure where to go from here.
I’ve heard about Apache Tomcat but not sure if it's necessary for what I need to do. If anyone can provide instructions / safe approaches about how to login to the Jenkins environment on my MAC from any network that would be appreciated.
To get jenkins web interface use $JENKINS_HOST_IP:8080 (by default jenkins uses port 8080) and then make first-run-configure.
Login to Jenkins from any machine on any network - it depends on network topology, what is used in your organisation. So, to reach jenkins host from any network where should be allowed traffic from/into network where jenkins host is placed.
Trigger a job - where are a lot of triggers you can use. Take a look at official documentation here
I am a web developer and I am currently using Vagrant + VirtualBox to run my projects. I have a Proliant server at home that I am not using at the moment. I was thinking, is there any way I could use it instead of the VM, so I could run my projects remotely?
P.S: Can you think about any other cool use cases for this server?
Vagrant is design to work with VMs or containers when using a docker provider but not bare metal server simply because the goal is to be able to build, use, destroy and rebuild environment programmatically so using a base-metal server break the main use case.
The possible course of action is to install the hypervisor on your personal server and then configure your Vagrantfile to use the remote provider instead of the local. You'll have as a direct benefit the ability to create a lot of instance since your server will most likely have more resources than your local laptop/desktop workstation.
I'm running an Ubuntu Server on an Amazon EC2 Service. And I'm using the Node-RED to create an IOT project on the cloud.
I succeeded configuring one machine in a way that it works for my project. My problem is when I clone this machine (creating an Amazon Machine Image of my original server and launching it as a new machine). I don't know why all the nodes that I've created on the graphical interface with the Node-RED disappear when I clone my Ubuntu Server. On my cloned server I just see a blank page when I access the Node-RED as if I had never created any node on the original server:
I think this is a problem with the Node-RED because I'm also running a Kibana instance on the same server and all Kibana's graphical configurations are preserved with the cloned server.
Does anyone know why this is happening? Is there a specific configuration on the Node-RED that I have to change to allow its graphical interface to be cloned?
OBS: I know I could just export everything that I did on the original server to my cloned server using the Node-RED import/export tools... But I'm planning to clone my original server many times, so it'd be better if everything were exactly the same when I clone the machine, without the need of manual work.
Node-RED stores the flow in a file in the ~/.node-red/ directory of the user running that instance, the file name is based on the host name of the machine.
e.g. on a raspberry pi the default flow file is called:
/home/pi/.node-red/flows_raspberrypi.json
So assuming that the host name gets changed when you "clone" the machine, Node-RED will not be able to find a flow file that matches the host name and as such start with an empty flow.
There are a few of ways to work round this.
if you start Node-RED manually from the command line you can specify the flow file as the last argument: node-red flow.json
if you are running Node-RED as a service then you can edit the ~/.node-red/settings.js to include a flowFile key that holds the name of the flow to use.
I'm current using Xammp,and have created a website in the htdocs. I want to know if i can access this from another computer (not in the same network) and work on the site from that other computer.
You can do this by using the dynamic dns service provided by noip.com. Download the noip client and setup an account in it (try Googling on it).
After that you must edit the conf files in XAMPP to allow outside network to communicate with your network.
I am trying to run a website from my computer using Spring Tool Suite (STS). Using pivotal tc Server I can access this website that I made by running the server and using localhost:8080 as a url.
My laptop contains other software that is permitted to only run in the laptop and it is needed to run my code in Spring tool suite.(School policy to SSH's into another computer to get access to my database; it is a requirement)
How would I be able to access that website that is running in my laptop that uses pivotal tc Server. Please assume I know nothing about IP address and DNS. Also, assume that I can move my laptop around like a mobile device.
To solve this problem you need to tunnel to your local machine
