passwordless ssh to another user instead of vagrant

[Shash]

Hi All,

I am new to this group and I have been trying out vagrant from past couple of months.

 I would like to have a passwordless ssh to another user in the vagrant guest. I tried a lot looking into various forums but in vain.

Can someone explain me here how to get this done.

Thanks!
Shash

Hello,

You require 2 options.

1. user + vagrant insecure key
2. user + known password

Documentation is here:
https://docs.vagrantup.com/v2/vagrantfile/ssh_settings.html

Option 1.

in the Vagrantfile you need to add:
config.ssh.username = user

in the base box under this user you need to add the vagrant insecure
key, which is what vagrant use to connect:

Assuming the box is linux, these are the commands I use to add vagrant
and to include the ssh key. Please modify to suit your box:

"useradd vagrant",
"cp /etc/sudoers /etc/sudoers.orig",
"sed -i -e '/# %wheel\tALL=(ALL)\tNOPASSWD: ALL/a
%vagrant\tALL=(ALL)\tNOPASSWD: ALL' /etc/sudoers",
"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",
"chmod 600 ~vagrant/.ssh/authorized_keys",
"chown -R vagrant: ~vagrant/.ssh"


Option 2.

In the Vagrantfile add:
config.ssh.username = user
config.ssh.password = somepassword

Let me know if you run into any issues.

Hi,

I would like to use my own key.

What I have done so far

Created a user in my guest machine.
Created ssh key in my host using ssh-keygen
Copied the ssh key to the guest using ssh-copy-id -p 2222 -i shash@127.0.0.1

and the part of the Vagrantfile looks like this

 config.vm.box = "ubuntu/trusty64" 
config.ssh.username = "shash" 
config.ssh.forward_agent = true 
config.ssh.private_key_path = "~/.ssh/authorized_keys"


 

I can use

ssh -p '2222' 'sh...@127.0.0.1'


to login directly but when I give

vagrant up

I keep getting the following error

default: Warning: Connection timeout. 
Retrying... default: Warning: Authentication failure. 
Retrying... default: Warning: Authentication failure. Retrying...

Any help in sorting out this is really appreciated.Thanks!

Hello,

Once you add the key to the box, and then update the vagrant, do a vagrant ssh

also add:
config.ssh.insert_key = false

it should work,

but it won't work on new boxes, since the user/key doesn't exist on the base box

what you need to do once you add the key to the box, is repackage and
create a new box

make sense?

Hi Alvaro,

Its still not working.

In your expert opinion, can you please let me know where I am going wrong?

Thanks

[Alvaro Miranda Aguilera]

I am not expert :)

I am not sure where the error can be, since if you can ssh directly to
the box, then after updating the Vagrantfile it should work

If you are open to a different approach, think you should build your
base box, and there you can use the user/pass/sshkey you want

if you are not going to use vagrant user, then later you need to
distribute or use your project file /Vagrantfile and that box

can you share what are the requirements for said box?

packer is a tool to build boxes, also made by hashicorp packer.io

there is an online tutorial that use the packer build in atlas that I
will suggest to run:
