When a command is executed an object representing the results of the execution is returned. We can execute commands against a session or sessions using the Invoke-SSHCommand command. To disconnect from the hosts we use the Remove-SSHSession PS> Remove-SSHSession -Index 0 -Verbose When the session is created, we can look at the session using the Get-SSHSession command PS> Get-SSHSession | flĮach session has the Index property that can be used with other commands or the object that is returned. We can see all the hosts we trust using the Get-SSHTrustedHost command and one can remove hosts from the trusts list using Remove-SSHTrustedHost: PS> Get-SSHTrustedHost | flįingerprint : 62:ef:96:b6:f8:a9:6c:7c:34:29:e6:d6:ba:59:ad:2f When we establish a new session for the first time it will check SSH server certificate fingerprint and IP address combination to those saved in HKEY_CURRENT_USER\Software\PoshSSH registry key if there is a mismatch it will generate an error that the fingerprint did not match and if it is not present it will show the fingerprint and ask if you want to trust or not the host before connecting: PS> New-SSHSession -ComputerName "192.168.1.191" -Credential (Get-Credential carlos)ĭo you want to trust the fingerprint 62:ef:96:b6:f8:a9:6c:7c:34:29:e6:d6:ba:59:ad:2f To see the examples, type: "get-help New-SSHSession -examples".įor more information, type: "get-help New-SSHSession -detailed".įor technical information, type: "get-help New-SSHSession -full". Specified the command will use the password in the credentials parameter as the paraphrase of the key. The command supports creating connection thru a Proxy and allows for authentication to the server using username and password. ] Ĭreates an SSH Session against a remote server. The command to create a new session is New-SSHSession PS> help New-SSHSessionĬreates an SSH Session against a SSH Server By allowing multiple sessions at once it allows me to control and automate tasks against more than one hosts and not have to re-login to each one. The way the module works is by establishing sessions to each of the hosts we want to run against. Once it finishes downloading and copying the module to the right place, it will list the commands available: This will download the latest version of Posh-SSH and install it in the user’s profile. The quickest way to install the module is by running: iex (New-Object Net.WebClient).DownloadString("") The module is hosted in GitHub at all source code for the cmdlets and for the module is available there and it is licensed under the BSD 3-Clause License. Posh-SSH was born out of my own technical needs and the opportunity to learn new things. It was an interesting experience in my journey of learning how to write a PowerShell module in C#. NET events and I decided to manage those in C# since examples where already present. Some of the tasks required the interaction with. I found the SSHT.NET library in CodePlex and just started implementing the code in PowerShell. I knew I could do this with Python- or Ruby-based great SSH libraries but I took it as a challenge to do it in PowerShell. I wrote the Posh-SSH module for automating testing of code I wrote in Ruby, Python and other languages in a lab environments where the code runs in a variety of systems than ranged from BSD Linux, OS X and Windows systems where I needed to only execute a series of commands and get the output. Supports DES-EDE3-CBC, DES-EDE3-CFB, DES-CBC, AES-128-CBC, AES-192-CBC and AES-256-CBC algorithms for private key encryption.Supports public key, password, and keyboard-interactive authentication methods.Supports 3DES-cbc, AES128-CBC, AES192-CBC, AES256-CBC, AES128-CTR, AES192-CTR, AES256-CTR, BlowFish-CBC, CAST128-CBC, ARCFour and TwoFish encryptions.Supports DIFFIE-HELLMAN-GROUP-EXCHANGE-SHA256, DIFFIE-HELLMAN-GROUP-EXCHANGE-SHA1, DIFFIE-HELLMAN-GROUP14-SHA1 and DIFFIE-HELLMAN-GROUP1-SHA1 key exchange methods.Uploading and downloading of files using SCP and SFTP.įrom the SSH standards it supports the following:.Execution of commands in a remote host using SSH Exec command.Connecting through SOCKS and HTTP proxies for both SSH and SFTP sessions.Establish SSH and SFTP sessions using credentials or OpenSSH keys.The module supports only a subset of the capabilities that the different SSH RFCs define but it allows for: Posh-SSH is a PowerShell 3.0 or newer module for automating tasks against system using the SSH protocol.
