Passwordless ssh to vagrant to load another user after vagrant ssh

Question

I have a new user in my vagrant box(trusty64) and I am trying to ssh into it. Instead of logging into vagrant user after vagrant up, I want to login to my username.

What I have done so far

1. Created a user in my guest machine.
2. Created ssh key in my host using ssh-keygen
3. Copied the ssh key to the guest using ssh-copy-id -p 2222 -i [email protected]

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' '[email protected]' 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!

Answer 1

config.ssh.private_key_path should point to your private key file (usually ~/.ssh/id_rsa — the name of the file is displayed when you run ssh-keygen), not ~/.ssh/authorized_keys.

Answer 2

An alternative way to accomplish this is adding the following to the bottom of ~vagrant/.bashrc:

ssh chsc
exit

If you want avoid the trouble of creating and installing an SSH key, you can use su instead; however this does not allow ssh inside the Vagrant box to use your SSH forward agent if you need to connect to external servers from within the box:

sudo su chsc
exit

When making such changes to ~vagrant/.bashrc you risk locking yourself out of the shell if you make an error. I recommend keeping an open terminal logged in as vagrant, until you have ensured that everything works. If something goes wrong, just rename .bashrc (mv .bashrc .bashrc-bak).
