Copssh - OpenSSH for Windows


Copssh is an OpenSSH server and client implementation for Windows systems with an administration GUI. You can use Copssh for remote administration of your systems or gathering remote information in a secure way.


Copssh - OpenSSH for WindowsCopssh packages portable OpenSSH, Cygwin and some popular utilites, plus implementing some best practices regarding security.

OpenSSH is a FREE version of the SSH protocol suite of network connectivity tools. It encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other network-level attacks. Additionally, OpenSSH fully supports SFTP server and client roles, provides a myriad of secure tunneling and forwarding capabilities as well as a variety of authentication methods. Cygwin is a Linux-like environment for Windows. It consists of a DLL (cygwin1.dll), which emulates substantial Linux API functionality, and a collection of tools.

Copssh installation


Supported platforms : Windows Vista/2008(R2)/7/8/2012(R2)/10/2016.

NB! Administrator privileges are required for installation and operation.

Copssh comes as a ZIP file containing an installer. Simply unzip your downloaded copy and run the package "Copssh_x.x.x_Installer.exe" :

  1. Accept License agreement.
  2. Specify an installation location.
  3. Specify a service account.
  4. Installation starts. By clicking 'Details' button, you can get more detailed information about installation. Check if everything seems ok.

You may check FAQ section or visit user forum if you experience problems. At the end of the installation, Copssh gives you some information about activation of users. You're DONE! Copssh is installed and the server portion is activated as a service.



By default, as a security measure, no users are allowed to access your machine via Copssh. You can use the Control Panel GUI from Start menu to activate/deactivate users. Same GUI can be used to control the basic Copssh operations as well.

Activated users can use an ssh client to access to your machine. My favorite is putty.

Password and public key authentication are tested and function as expected.
