Unable to connect using PuTTY ssh

putty

I'm on a Windows 7 machine and have installed PuTTY. I'm trying to connect, but the authentication fails because of an incorrect password. But, the VM I'm connecting to doesn't have a password?

Here are the creds I'm trying to use:
Host: 127.0.0.1
Port: 2222
Username: vagrant
Private key: c:/users//.vagrant.d/insecure_private_key

When I open PuTTY, I put in the above credentials and click open, at which point it ask for the username and I enter 'vagrant', then it asks for the password, but there isn't a password, so I get access denied?

Not sure how to get around this?

Thanks.

The first thing you need is a key that PuTTY can understand. PuTTY requires a .ppk file, which is not the same as the standard openSSH key file. You can use the PuTTYgen tool to generate a key or to convert an existing openSSH to a putty key.

Once you have a key, you need to tell PuTTY about it. For this you have two options:

Once you have PuTTY all setup, you need to make sure you have added your public key to the authorized_keys file. Once that is all setup you should be able to connect.

Linux – Putty on Linux not working with username in host name field

It does look like you can't specify a username in the putty GUI. However, you do not need to use putty if what you want to do is connect to other linux hosts over ssh. Just open a terminal and type:

ssh user@host

This will do exactly what putty does for you in windows.

If you want putty in order to save connections, add lines like the following into your ~/.bashrc file (the following are adapted from mine):

alias myserver='ssh myuser@myserver'
alias petitbonum='ssh bob@petitbonum' 
alias docpad='ssh terdon@docpad.local'
alias badabing='ssh -Y lacoloc@1.2.3.4'

Obviously, change the user and server names and/or IPs to whatever you need. Then, you open a new terminal and type, for example, myserver and hit enter. This will run the command defined in the alias you placed in .bashrc.

How to configure putty to ssh to multiple vm using same host

You can't. You need to modify something - the easiest something to modify is probably your SSH config - maybe you can modify ssh to listen on an alternative port (maybe by modifying /etc/ssh/sshd on the hosts and restarting it), and/or modifying the ListenAddress so it binds to all interfaces so you can access it by IP address.

[ I can only speculate the exact steps you need to take - they will depend on your specific configuration. I suspect you will actually need to enable SSh on the machines, and that your SSH sessions on port 2222 are something set up by Virtualbox with some kind of forwarding. - I don't use Virtualbox though]

The reason why looking in your network configs to have 2 x 127.0.0.1 connections won't help with respect to "127.0.0.1" is that 127.0.0.1 ALWAYS refers to "This machine", thus there is no way to connect to these.
