After you have created a new Cloud Server with the Cloud Control Panel, you need to make a secure remote connection from your local computer to your Cloud Server. This article describes how to use a client called PuTTY to form a Secure Shell (SSH) connection from a computer running a Microsoft® Windows® operating system (OS) to a Linux® server.
Note: This procedure requires you to install PuTTY or another SSH client, which you do at your own risk. PuTTY is not affiliated with Rackspace in any way, but the software is simple to use, freely available, and reputable.
If you are a MacOS® X user, you can connect to a Linux server by using Terminal, a console program included with the operating system.
For an OnMetal server, see Create OnMetal Cloud Servers for applicable OnMetal steps.
The procedure and examples in this article use Windows XP, Service Pack 2. Different versions of Windows might have slightly different interfaces.
Use the following steps to download and open PuTTY:
Download PuTTY from the PuTTY website.
Ensure that you comply with the license requirements.
Launch the client.
Use the following steps to configure your connection:
In the PuTTY Configuration window, enter the following values:
If this is the first time that you have used PuTTY to log in to your server with SSH, a warning similar to the following one displays:
The server’s host key is not cached in the registry. You have no guarantee that the server is the computer you think it is. The server’s rsa2 key fingerprint is: <string>. If you trust this host, hit **Yes** to add the key to PuTTY’s cache and carry on connecting. If you want to carry on connecting just once, without adding the key to the cache, hit No. If you do not trust this host, hit Cancel to abandon the connection.
If you are sure that you have entered the correct information, click Yes.
Subsequent connections do not show this warning because the host key is now cached in the registry of your local computer. You can expect to see that warning, however, if you connect to your server from a different computer.
After you accept the warning, the terminal prompts you for your username and password.
If this is the first time that you are logging in to the server, you must log in as the root user.
When you are prompted for the password for the root user, enter the current root password for this server. The password at is not echoed to the screen. Then, press Enter.
If you have entered the correct root password, the prompt responds with a shell prompt:
Now you can work on your server with all permissions.
We recommend that you change the root password to something personal.
You can easily do this by using the
passwd command and the following steps:
When you connect to your server, use this password with the root user.
