VM network connection problem during vagrant setup?

[Alle Meije Wink]

For setting up an XNAT from scratch I chose to use the 'vagrant' method.

(after losing one that was set up on the OS, which was a lot of work)

Following the documentation on

  https://wiki.xnat.org/documentation/getting-started-with-xnat/running-xnat-in-a-vagrant-virtual-machine

I used these commands (as root, from the /root directory):

$ apt install vagrant
$ apt install git

$ apt install virtualbox

$ git clone --branch master https://bitbucket.org/xnatdev/xnat-vagrant.git && cd xnat-vagrant && ./run xnat setup

Everything goes automatically, no difficult choices to make, brilliant. Until there is an error when the VM starts.

It appears that the VM cannot connect to the network via the host machine because of a problem with the SSH daemon?

I'm not sure that I understand correctly what the problem is. Does anyone know?

Many thanks!

This is the error message:

An error occurred in the underlying SSH library that Vagrant uses.
The error message is shown below. In many cases, errors from this

If the problem persists, please report a bug to the net-ssh project.

[Herrick, Rick]

What platform are you running on? I’m wondering if there could be an issue with some security service on the host machine, e.g. selinux or something similar, that’s blocking the network connection between the VM and host.

 

A good test would to try to bring up a really vanilla VM under Vagrant. I’ve attached a dead simple configuration to this email, but the contents are short:

 

Vagrant.configure("2") do |config|

    config.vm.define "ubuntu-1604"

    config.vm.box = "bento/ubuntu-16.04"

    config.vm.network "private_network", ip: "10.1.1.16"

    config.vm.hostname = "ubuntu16"

 

    config.vm.provider "virtualbox" do |v|

        v.name   = "ubuntu-1604"

        v.memory = "2048"

        v.cpus   = 1

    end

end

 

You can change the IP, host name, VM name, whatever, or even change the box (that said, the current xnatstack box used by the XNAT Vagrant project is based on bento/ubuntu-16.04 or something similar, so that’s a good comparison). The important thing is to use the “private_network” setting for the network configuration. Just save the Vagrantfile to some folder, cd to that folder, then run:

 

$ vagrant up

 

If that works for you, then there’s something weird in the XNAT Vagrant configuration causing the error, but if not then there’s something on your system causing an issue.

Thanks for your directions! Yes, I do get the same errors with your Vagrantfile as well, running either as root or non-root user.

I'm posting the output (again) below. So even though it seems to be a machine setup thing and not XNAT specific, I'd be grateful if someone can tell what this means :)
