使用Powershell远程登录linux

Question

I am using the following script (ssh module)to remotely login to a linux server to start a process. This 'prompts' me for the credentials at the command line. I am trying to run this script through Bamboo So, is there a way I can pass the credentials while I run the script like, so that it wont prompt me for credentials while running the script?

PS C:\SVN_Working> .\linux-maint.ps1 -UserName user1 -Password pass123

    $agents=("cagent01")
      function Start-LinuxAgents([array]$agents){
          if ($agents.length -gt 0){
              $agents | %{
                  New-SshSession -ComputerName $_
                  $ExecStart = Invoke-SshCommand -InvokeOnAll -Quiet -Command './start'
                  Remove-SshSession -ComputerName $_
              }
          }
      }

SSH has the ability to authenticate users via a password, or via a public/private keypair.

You could create a private key with no password, add the public key to ~/.ssh/authorized_keys on the Linux server, and then specify your private key when creating a session via New-SshSession in the script.

See http://www.powershelladmin.com/wiki/SSH_from_PowerShell_using_the_SSH.NET_library#New-SshSession

and on generating a public/private SSH key: https://help.github.com/articles/generating-ssh-keys/

*note: If you create an SSH key without a password, it means that anyone who has possession of that private key can access any system with the matching public key. This is a security risk - you may want to look into restricting the commands the user is allowed to run on the remote system (also part of SSH's functionality)
