Our SSH client supports all desktop and server versions of Windows, 32-bit and 64-bit, from Windows XP SP3 and Windows Server 2003, up to the most recent – Windows 10 and Windows Server 2019. Our client is free for use of all types, including in organizations. To begin, simply download it here.

SSH is based on a client-server architecture where the system the user is working on is the client and the remote system being managed is the server. OpenSSH includes a range of components and tools designed to provide a secure and straightforward approach to remote system administration, including.

5.1About the Cygwin Requirement for Installing Management Agents

The Add Host Targets Wizard is an application built into the Enterprise Manager Cloud Control console. It offers GUI-rich, interactive screens that enable you to install Oracle Management Agents (Management Agents) on unmanaged hosts and convert them to managed hosts, so that they can be monitored and managed in Enterprise Manager Cloud Control.

When you use the Add Host Targets Wizard or EM CLI to install a Management Agent on a host running on Microsoft Windows, as a prerequisite, you must install Cygwin and start the SSH Daemon on the host. To do so, follow the steps listed in Section 5.3.

Cygwin is essentially a utility that offers a Linux-like environment on a Microsoft Windows host. Technically, it is a DLL (cygwin1.dll) that acts as a Linux API layer providing substantial Linux API functionality. Once you install Cygwin, you can configure the SSH Daemon on the host. The Add Host Targets Wizard is certified and supported with Cygwin 1.7.

The SSH Daemon enables the Add Host Targets Wizard to establish SSH connectivity between the OMS host and the host on which you want to install a Management Agent. Using this connectivity, the wizard transfers the Management Agent software binaries to the destination host over SSH protocol, installs the Management Agent, and configures it.

5.2 Before You Begin Installing Cygwin

Before starting with the SSHD setup, ensure you are not using OpenSSH and MKSNT when using the Add Host Targets Wizard. To do so, perform the following checks:

1. Ensure OpenSSHbin and mksnt are not in your PATH environment variable. If they are, remove them by doing the following:

   1. Right-click on My Computer and go to Properties.

   2. In the System Properties window, click Advanced.

   3. In this tab, click Environment Variables.

   4. Here, search for the PATH system variable, select it, and if the OpenSSHbin and mksnt are present in PATH, click Edit.

   5. In the Edit System Variable dialog box, delete these two values from PATH,then click OK.

   
   

2. Stop the SSH Daemon if it is running from OpenSSH, MKS or any other vendor. If the SSH Daemon is running, stop it by doing the following:

   1. Right-click on My Computer, and select Manage.

   2. In the Computer Management window, in the left pane, expand Services and Applications, and select Services.

   3. In the right pane, click the SSH Daemon/MKS Secure Shell service, then click the Stop button.

   
   

Note:

The navigational steps described in this section may vary for different Microsoft Windows operating systems.

5.3 Installing Cygwin

To install Cygwin on a Microsoft Windows host, follow these steps:

1. Access the following URL, then click Install Cygwin:

2. Download the 32-bit version (if you are running a 32-bit version of Microsoft Windows) or the 64-bit version (if you are running a 64-bit version of Microsoft Windows) of the Cygwin setup executable.

5.4 Configuring SSH

This section describes how to configure SSH and test your Cygwin setup after installing Cygwin on a host.

Note:

While configuring SSH, you may need to run the cygwin.bat script. While running cygwin.bat in Microsoft Windows Server 2008 and Microsoft Windows Vista, ensure that you invoke it in administrator mode. To do this, right-click the cygwin.bat file and select Run as administrator.

To configure SSH and test your Cygwin setup, follow these steps:

1. After you install Cygwin, navigate to the C:cygwin directory, open the Cygwin.bat file in edit mode using any editor, and add the following line before invoking the bash shell.

   set CYGWIN=binmode ntsec

   For example, here are the contents for the Cygwin.bat file after adding the above line:

2. To verify if Cygwin (cygrunsrv) is installed properly, run C:cygwinCygwin.bat, and execute the following command:

   If Cygwin is installed properly, then all the Cygwin help options are displayed on the screen. However, if this command returns an error message, then you may have to reinstall Cygwin.

3. To configure the SSHD service, run C:cygwinCygwin.bat, and execute the following command:

   After running the command, you are prompted the following questions:

   At this point, if you want to use the same name, that is cyg_server, enter no. You are then prompted the following questions:

   However, if you want to use a different name, enter yes. You are then prompted the following questions:

   If the configuration is successful, you will see the following message:

4. Backup the c:cygwinetcpasswd file and then use any editor to open the file in edit mode. Remove only those entries of the user that you will use to connect to the host on which you want to install a Management Agent. Ask the user to make a backup of the c:cygwinetcpasswd file before editing.

   • If the user that you are employing to connect to the host on which you want to install the Management Agent is a local user, run C:cygwinCygwin.bat and execute the following:

   • If the user you are employing to connect to the host on which you want to install the Management Agent running is a domain user, run C:cygwinCygwin.bat and execute the following:

5. (Only if the Cygwin software you have installed is of version 1.7.32 or higher) Open C:cygwinetcsshd_config in a text editor and add the following line to the end of the file:

   KexAlgorithms diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

6. (For a domain user only) If the user you are employing to connect to the host on which you want to install the Management Agent is a domain user, do the following to start the SSH daemon:

   1. Right-click on My Computer, and select Manage.

   2. In the Computer Management dialog box that appears, go to Services and Applications, and select CYGWIN sshd.

   3. Right-click CYGWIN sshd and select Properties.

   4. In the Properties dialog box, go to the Log On tab.

   5. Here, specify the domain/user name and password. Click Apply.

   6. Run C:cygwinCygwin.bat, and execute the following:

      Note:

      If /var/log/sshd.log does not exist, you do not have to execute the following commands:

7. Perform one of the following steps to start the SSH daemon:

   Run C:cygwinCygwin.bat and execute the following command:

   /usr/sbin/sshd

   OR

   Run C:cygwinCygwin.bat and execute the following command:

   cygrunsrv -S sshd

   OR

   Perform these steps:

   1. Right-click on My Computer, and select Manage.

   2. In the Computer Management dialog box that appears, go to Services and Applications, and select CYGWIN sshd.

   3. Click CYGWIN sshd, then click the Start button.

   
   

   Note:

   If the SSH daemon does not start up, view the c:cygwinvarlogsshd.log file for information on why the start up failed.

8. You can now test your Cygwin setup.

   To do this, go to a different machine (that has the ssh client running), and execute the following command:

   For example,

   This command will prompt you to specify the password. When you specify the correct password, the command should return the accurate date.
