Open Source SSH Power.Shell Module. What.Posh SSH is a Power.Shell 3. 0 or newer module for automating tasks against system using the SSH protocol.The module supports only a subset of the capabilities that the different SSH RFCs http en.SecureShell define but it allows for Establish SSH and SFTP sessions using credentials or Open.SSH keys. Connecting through SOCKS and HTTP proxies for both SSH and SFTP sessions.Execution of commands in a remote host using SSH Exec command.Uploading and downloading of files using SCP and SFTP.From the SSH standards it supports the following Supports DIFFIE HELLMAN GROUP EXCHANGE SHA2.DIFFIE HELLMAN GROUP EXCHANGE SHA1, DIFFIE HELLMAN GROUP1.SHA1 and DIFFIE HELLMAN GROUP1 SHA1 key exchange methods.Supports 3. DES cbc, AES1.CBC, AES1. 92 CBC, AES2.CBC, AES1. 28 CTR, AES1.CTR, AES2. 56 CTR, Blow.Fish CBC, CAST1. CBC, ARCFour and Two.What. PoshSSH is a PowerShell 3.SSH protocol. The module supports only a subset of the capabilities.Fish encryptions.Supports HMAC MD5, HMAC SHA1, HMAC RIPEMD1.HMAC SHA2 2. 56, HMAC SHA2 2.HMAC MD5 9. 6 and HMAC SHA1 9.Supports public key, password, and keyboard interactive authentication methods.Supports RSA and DSA private key.Supports DES EDE3 CBC, DES EDE3 CFB, DES CBC, AES 1.CBC, AES 1. 92 CBC and AES 2.CBC algorithms for private key encryption.Winscp 4 3 3 Executions' title='Winscp 4 3 3 Executions' />Supports SOCKS4, SOCKS5 and HTTP proxy.Why. 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.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 Power.Shell. I found the SSHT.NET library in Code.Plex http sshnet.Power. Shell. Some of the tasks required the interaction with.Winscp 4 3 3 Executions This WeekWinscp 4 3 3 Executions In ArkansasNET events and I decided to manage those in C since examples where already present.It was an interesting experience in my journey of learning how to write a Power.Shell module in C.Posh SSH was born out of my own technical needs and the opportunity to learn new things.Install. The module is hosted in Git.Hub at https github.Posh SSH all source code for the cmdlets and for the module is available there and it is licensed under the BSD 3 Clause License.The module requires Power.Shell 3. 0 and. NET Framework 4.The quickest way to install the module is by running.New Object Net. Web.Client. Download.Stringhttps gist.This will download the latest version of Posh SSH and install it in the users profile.Once it finishes downloading and copying the module to the right place, it will list the commands available Connecting.The way the module works is by establishing sessions to each of the hosts we want to run against.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 command to create a new session is New SSHSession.PS C help New SSHSession.New SSHSession.

Creates an SSH Session against a remote server.The command supports creating connection thru a Proxy and allows for authentication to the server using username and password.If a key file is.To see the examples, type get help New SSHSession examples.For more information, type get help New SSHSession detailed.For technical information, type get help New SSHSession full.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 HKEYCURRENTUSERSoftwarePosh.SSH 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 C New SSHSession Computer.Name 1. 92. 1. 68.Credential Get Credential carlos.Server SSH Fingerprint.Do you want to trust the fingerprint 6.Y N Help default is N Y.Index Host Connected.True. We can see all the hosts we trust using the Get SSHTrusted.Host command and one can remove hosts from the trusts list using Remove SSHTrusted.Host. PS C Get SSHTrusted.Host fl.

Client.Each session has the Index property that can be used with other commands or the object that is returned.To disconnect from the hosts we use the Remove SSHSession.PS C Remove SSHSession Index 0 Verbose.VERBOSE Removing session 0.VERBOSE Session 0 Removed.Executing Command.We can execute commands against a session or sessions using the Invoke SSHCommand command.When a command is executed an object representing the results of the execution is returned.When executed it instantiates on the system a new instance of the default shell configured on the system, executes the command and returns an object and the exit status of the last command executed.PS C Invoke SSHCommand Index 0 Command uname a.Host 1. 92. 1. Output Linux testdebian.SMP Debian 3. 2. 5.GNULinux. In the case of LinuxUnix systems when the command string is given to the shell, the instance is closed so it will retain the state because the shell instance is closed after each execution.PS C Invoke SSHCommand Index 0 Command pwd.Host 1. 92. 1. Output homecarlos.PS C Invoke SSHCommand Index 0 Command cd.Host 1. 92. 1. PS C Invoke SSHCommand Index 0 Command pwd.Host 1. 92. 1. Output homecarlos.But in the case of Linux or Unix we can chain command with the shell command terminator and have the shell run them.PS C Invoke SSHCommand Index 0 Command uname a cd pwd ls l.Host 1. 92. 1.
