ssh requires password between systems

[Joaquin Menchaca]

What's the easiest way to fix this?  I have a multi-system configuration, when I try to SSH into them on my private network, I am prompted for a password.  Thus inside workstation01, I try "ssh 192.168.50.5", and I am prompted for a password.

My Vagrantfile

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

  config.vm.define "work" do |work|

    work.vm.box = "hashicorp/precise64"

    work.vm.hostname = "workstation01"

    work.vm.network "private_network", ip: "192.168.50.4"

  end

  config.vm.define "server" do |server|

    server.vm.box = "hashicorp/precise64"

    server.vm.hostname = "server01"

    server.vm.network "private_network", ip: "192.168.50.5"

  end

end

Hello,

Couple of options.

1. you can tell vagrant to not change the known insecure key.

config.ssh.insert_key = false

and then on each box, just copy the private key, so they will identify
as the vagrant, and should work.

2. Use a post script at the end to that, since at that stage the keys
will have been setup.
Just not usre if will be the same private key for all the boxes, so
you need to make

- each box copy the private
- every box to add the public of the rest and authorized_keys

be sure to set correct permissions at the end

chown -R vagrant: /home/vagrant/.ssh
chmod -R 0600 /home/vagrant/.ssh
chmod 0700 /home/vagrant/.ssh

Hope this helps
Alvaro

Ultimately, through numerous more complex trials, figured this was the easiest route, using the shell provisioner, placing something like this:

    config.vm.provision "shell", path: "setup-all.sh"    # ssh convenience

The script in question does the following:

cat <<- CONFIGEOF > /etc/ssh/ssh_config

Host server01

  StrictHostKeyChecking no

  UserKnownHostsFile /dev/null

  IdentitiesOnly yes

  User vagrant

  IdentityFile /vagrant/.vagrant/machines/server/virtualbox/private_key

  PasswordAuthentication no

Host workstation01

  StrictHostKeyChecking no

  UserKnownHostsFile /dev/null

  IdentitiesOnly yes

  User vagrant

  IdentityFile /vagrant/.vagrant/machines/work/virtualbox/private_key

  PasswordAuthentication no

CONFIGEOF

echo '192.168.50.4 workstation01' >> /etc/hosts

echo '192.168.50.5 server01' >> /etc/hosts

After this, everything magicaliciously works.
