Vagrant ssh error

[STARFISH]

Hi Here,

I created one vagrant file and from that I used to create the package box.

With the help of the package box, while I try to start the another vm, its having the below warning, its not starting.. I Have no idea how to fix this.

default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Remote connection disconnect. Retrying...
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...

Its started, but not connected and the vagrant ssh is not working

Rameshs-MacBook-Pro:vag_cent7_2 Ramesh$ vagrant ssh
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

Below is my vagrant file.

Rameshs-MacBook-Pro:vag_cent7_2 Ramesh$ cat Vagrantfile

Vagrant.configure(2) do |config|

  config.vm.box = "/Users/Ramesh/lab_ansible/vag_cent7_1/package.box"
  config.vm.hostname = "server2"

end

Help me on fixing this.

the message is telling the ssh key on the guest have permissions issues

can you share your script?

this is what I use, just remove the    "    and    ",

	"mkdir ~vagrant/.ssh",
	"chmod 700 ~vagrant/.ssh",
	"echo 'ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA6NF8iallvQVp22WDkTkyrtvp9eWW6A8YVr+kz4TjGYe7gHzIw+niNltGEFHzD8+v1I2YJ6oXevct1YeS0o9HZyN1Q9qgCgzUFtdOKLv6IedplqoPkcmF0aYet2PkEDo3MlTBckFXPITAMzF8dJSIFo9D8HfdOV0IAdx4O7PtixWKn5y2hMNG0zQPyUecp4pzC6kivAIhyfHilFR61RGL+GPXQ2MWZWFYbAGjyiYJnAmCP3NOTd0jMZEnDkbUvxhMmBYSdETk1rRgm+R4LOzFUGaHqHDLKLX+FIPKcF96hrucXzcWyLbIbEgE98OHlnVYCzRdK8jlqm8tehUc9c9WhQ== vagrant insecure public key' > ~vagrant/.ssh/authorized_keys",

I tried the same by generating the new ssh key, and then redirect to the authorized keys, still the same error.

ssh-keygen -t rsa -b 4096 -C "Vagrant"
cat vagrant.pub > ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

-- Already its owned by vagrant, so skipped this step.

After vagrant reload, got the same error

hello

you need:

- a known private/pub key, not just any key.

- The ssh is from the host to the guest, so adding a new pair guest-to-guest wont help.

- permissions need to be for all the content 0600 and folder 0700

If you could run my provided script and test `vagrant ssh` it will show more information.

hello

can we go slowly on this one?

in the commands you run the vagrant user doesnt exist in your host, seems you want to run those in the guest ?

by default, vagrant on first start will try to change the keys to a more secure one

what i could suggest is add config.ssh.insert_key = false  on the Vagrantfile you are using to create this new vagrant box

in this way, when you package the ssh part will be the vagrant default one

Can you work on a minimal test?

create a simple vgrant file

do some change on the guest

export the new vm as package.box

test the box in a new vm

profit

if you can put all this in a github repo, will be easier to review and comment

thanks

alvaro

As advised,  I removed all the boxes appeared on my host machine.  And created new box, and still the authentication failure happening.

https://gist.github.com/ramesh4f/0da12c1e45860733b80671aee2df6ade#file-vagrant-creation-txt

I added the below changes too  `config.ssh.insert_key = false` .

Please review the gist link

hello,

if you did something like yum update, that requires a reboot and recompile virtualbox guest modules

so is easier do

yum update --exclude kernel*

now, if your goal is create boxes that will be used later, at somepoint you should look into use packer with virtualbox-ovf

Hi Alvaro,

This is my full set of thing’s I worked.

I created one vagrant with ansible installed. I would like to use this for creating 2 more similar instances.

For that the after created first one, and for the second one, I created

Rameshs-MacBook-Pro:vag_cent7_1 Ramesh$ vagrant package

==> default: Clearing any previously set forwarded ports...
==> default: Exporting VM...
==> default: Compressing package to: /Users/Ramesh/lab_ansible/vag_cent7_1/package.box

After that I created the new vagrant box

 vagrant box add --name server2 /Users/Ramesh/lab_ansible/vag_cent7_1/package.box --provider virtualbox

Rameshs-MacBook-Pro:boxes Ramesh$ mv server2 ansible_lab 

Now I can connect without ssh password asking, but getting the shared file directory error.

^R

Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:

mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant

The error output from the last command was:

mount: unknown filesystem type 'vboxsf'

​

Help me on fixing this, as Im new to this one.
