Connect to a VPS with PuTTy via PasswordĪfter opening PuTTY, you should see a screen that looks something like this: After it has finished being installed, start up PuTTY. Once you have downloaded the appropriate file, double-click on the installation icon, and run the Windows installer. If you are still unsure, you can always choose the 32-bit version it should run without trouble on either system. You will be provided all the necessary information. If you are unsure of whether you are running a 32-bit or 64-bit system, you can check by right-clicking on the Windows Start menu and choosing “System”. You'll need too choose the appropriate *.msi installation file for your system while doing so.

First, if you have not done so already, you will want to download PuTTY. To get PuTTY working requires a small amount of configuration.

PuTTY is a free utility which will allow command-line access to your server. When connecting to your Linux-based VPS from a Windows system, the most common way of doing that is via SSH, using PuTTY.

You can also passphrase or password to protect it or restrict access to the file.Feel free to sign up to BitLaunch for use in this PuTTy VPS tutorial. Like I mentioned, there must be a handshake between the private key and the public key. One good practice is to delete the private keys except when you need them to login to another Linux system or login as a different user or root user. 1 tayo tayo 566 Nov 17 16:03 authorized_keys The “.ssh” folder should have the permission, 700 which comes mostly by default, and the authorized_keys file should have the permission, 600 ~]$ chmod 600. Note that you will need to change the permission of authorized_keys to 600 if you are having the error, “the server refused our key” as shown after step 11 below.

SHA256:alUVV69Vwp/XmDRFNpR6iXXrk744MptKvRLSws2PgPE key's randomart image is:ģ. Your public key has been saved in /home/tayo/.ssh/id_rsa.pub. Your identification has been saved in /home/tayo/.ssh/id_rsa. Enter passphrase (empty for no passphrase): If you want to always login automatically without a passphrase, don’t enter any, just press the enter key on your keyboard and move on. Enter file in which to save the key (/home/tayo/.ssh/id_rsa):Įnter passphrase (empty for no passphrase):īecause I want the user, tayo to always login via the keys using a passphrase, I will enter a passphrase. You must generate a key pair for individual users on the system, just like you are creating passwords for every user if you disable using SSH password login. In this snippet, I will be using the ssh-keygen tool ~]$ ssh-keygenĮnter file in which to save the key (/home/tayo/.ssh/id_rsa):īecause I am generating this key pair for the user, tayo, I will like to save the key pair in tayo’s home directory, so I will accept the default location to save the files to.

The most important thing is that you have the two key pairs, public and private keys, where your public key will be on the Linux system, and your private key will be on the windows system.

You can use the PuTTY Key Generator (PuTTYgen) tool on windows or the ssh-key tool on Linux.
