# Connect to remote CLI devices via PuTTY and Command prompt

## How to connect to remote devices and execute commands using PuTTY and command prompt?

CLI access can be tested in two ways:

- [Connection and command execution via PuTTY](https://www.manageengine.com/network-monitoring/how-to/cli-connection-via-putty.html#putty-method)
- [Connection and command execution via Command Prompt](https://www.manageengine.com/network-monitoring/how-to/cli-connection-via-putty.html#cmd-method)

## Connection and command execution via PuTTY

- Launch the PuTTY application on the OpManager server. The PuTTY Configuration window should appear.
- In the **Host Name (or IP address)** field, enter the remote machine name.

**Note:** The remote machine name will be either the DNS Name or IP Address, depending on the poll-using option set in OpManager.

- In the **Connection type** field, choose either **SSH** or **Telnet**.
- Based on the connection type, the default port number will be updated in the **Port** field. If the remote machine is configured to use a different port, update the port number accordingly.

**Note:** The connection type and port number must match the credential profile associated with the device in OpManager.

- Click **Open** to initiate the connection.

## Connection and command execution via Command Prompt

- Open the **Command Prompt** on the OpManager-installed server in administrator mode.
- Enter the following command to establish a remote connection:

```
connectionType username@deviceName -p portNo
```

- Replace the placeholders as follows:
  - **connectionType**: Use either **SSH** or **Telnet**.
  - **username**: The remote machine's username associated with the device in OpManager.
  - **deviceName**: The remote machine's DNS Name or IP Address, based on the poll-using option set in OpManager.
  - **portNo**: The port number based on the connection type. The default port for SSH is **22**, and for Telnet, it is **23**.
- **Example:**

```
ssh test@devicename -p 22
```

- Enter the proper **password** and press **Enter**.
