Generate a new SSH key pair You can secure SSH access to your cloud server against brute force password attacks by using a public-private key pair. Use the following steps to generate an SSH key pair: Your key pair is generated, and the output looks similar to the following example: The key fingerprint is: Add the public key to your cloud account To make it easy to add your key to new cloud servers that you create, upload the public key to your cloud account by following these steps: Log in to the Cloud Control Panel.

Click Add Public Key. Enter a key name, such as Work Laptop , to remind you which computer this key is for. Select the region for which you want to store the public key. To store your key in multiple regions, repeat these steps for each region. The key must reside in the same region as the server.

You can get the file contents by either opening the file in a text editor or by running the following command: If you want to add the key manually, instead of by using the Control Panel, review Linux server security best practices and use the following command: From the SSH Key menu, select your key from the list. Switch the region for the new server to the region where you have stored the SSH key. Repeat the steps in the preceding section, Add the public key to your cloud account , to add the key to the region in which you want to create the new server.

Follow these steps to add the key manually: Set the correct permissions on the key by using the following commands: A shortcut name that you use to tell SSH to use this connection.

The address of the server to which you connect. The name of the user account to connect to on the server.

After you set up the config file, connect to the server by using the following command with your shortcut name: For RPM servers, run the following command to watch the log: Unless the gateway ports option is enabled, the forwarded local port is available only to clients running on the same computer as the Secure Shell client. The optional protocol can be tcp or ftp.

Multiple client applications can use the forwarded port, but the forward is active only while ssh is running. If the final destination host and port are not on the Secure Shell server host, data is sent in the clear between the Secure Shell host and the application server host. You can also configure local forwarding in the configuration file using the LocalForward keyword.

Specifies, in order of preference, which MACs message authentication codes are supported by the client.

Enabling Remote Login

Allowed values are 'hmac-sha', 'hmac-sha1', 'hmac-sha', 'hmac-md5', 'hmac-md', 'hmac-sha', and 'hmac-ripemd'. Use 'AnyMac' to support all of these. Use 'AnyStdMac' to specify 'hmac-sha, hmac-sha1,hmac-sha,hmac-md5,hmac-md, hmac-sha'. Specifying hmac-sha also enables hmac-sha Multiple MACs can also be specified as a comma-separated list. When 'none' is the agreed on MAC, no message authentication code is used. Because this provides no data integrity protection, options that include 'none' are not recommended.

You can also configure this in the configuration file using the DontReadStdin keyword. Sets any option that can be configured using a configuration file keyword. Syntax alternatives are shown below. Use quotation marks to contain expressions that include spaces. To configure multiple options, use multiple -o switches.

Specifies the port to connect to on the server.

The default is 22, which is the standard port for Secure Shell connections. You can also configure the port in the configuration file using the Port keyword. Enables quiet mode, which causes all warning and diagnostic messages, including banners, to be suppressed. You can also configure this in the configuration file using the QuietMode keyword. Redirects data from the specified remote port on the computer running the Secure Shell server , through the secure tunnel to the specified destination host and port.

Configure your client application the one whose data you want to forward to send data to the forwarded socket rather than directly to the destination host and port. When that client establishes a connection, all data sent to the forwarded port is redirected through the secure tunnel to the Secure Shell client, which decrypts it and then directs it to the destination socket host,hostport.

You can also configure remote forwarding in the configuration file using the RemoteForward keyword. Invokes the specified subsystem on the remote system. Subsystems are a feature of the Secure Shell protocol which facilitates the use of Secure Shell as a secure transport for other applications such as sftp. Subsystems must be defined by the Secure Shell server. Connects without requesting a session channel on the server.

This can be used with port-forwarding requests if a session channel and tty is not needed, or the server does not give one. Forces a tty allocation even if a command is specified. Sets the debug level to verbose mode, which is equivalent to using '-d 2'. The -v flag is to enable verbose logging, and it is useful to see the percentage, speed and the list of files transferred.

SSH Command in Linux

If you want to transfer a directory on your current computer to the home folder on your Mac, you can run:. On a terminal window, type:. Sometimes, you may need to change the preferences for the SSH server. For example, you may want to run SSH on a different port to thwart attackers, or you may want to disable password authentication. Open up a terminal window and type in:.

Next, you should restart the server for your changes to take effect. In the terminal window, run these commands:. SSH is a pretty nifty thing to have on your system.
