- On Linux, use Terminal application. This application is available in every distributive.
- MacOS X also has Terminal.app installed by default.
- For Windows, use PuTTY to do remote SSH logins from Windows. You can download PuTTY for free.
Connecting to a Linux server
The most simple way to login to Linux Server is using a password as an authentication mechanism. Check the information below to learn how to login to a Linux server using a username and private key.
Login from Linux or MacOS X with a password
Linux, MacOS X and most UNIX variants have SSH installed by default, you don't need to install any additional packages.
To login to a Linux server using ssh use the following command:
$ ssh username@server
Another way to login is using the -l option for username :
$ ssh server -l username
In case you need to access a server that is not using SSH default port (22), you can specify an SSH server port number using
-p option. In the example below the SSH port is 2222.
$ ssh server -l username -p 2222
Here is an example of a connection to the server example.com using the username
$ ssh example.com -l root The authenticity of host 'example.com (192.168.0.200)' can't be established. RSA key fingerprint is 90:8c:7d:f8:ae:1a:09:60:44:08:3b:d9:c9:f7:c4:76. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'example.com' (RSA) to the list of known hosts. firstname.lastname@example.org's password:
The warning above is shown if you are connecting to the server for the first time. The SSH client will check the authenticity of the server by checking the SSH fingerprinting. Since this is a first-time connection, SSH does not have any record of this server fingerprint and will ask you whether you want to trust this server or not. You can type
yes on the question above and input your password.
If you have logged into this server before and you get this message again there are several possibilities that could happen :
- Your server is reinstalled and of course, the SSH fingerprint changed.
- Your server compromised or someone acts as a man in the middle (MITM), so instead of connecting to the real server, you are connecting to the MITM machine.
- Wrong change on DNS records entry so you are connecting to the wrong server.
Log in with a private key on Linux or MacOS X
For a private key login, use the following command:
$ ssh -i keyfile username@server
-i will tell SSH which private key to use.
Login from Windows with a password
For this, it is required to download Putty client and run it.
- Enter the server's address, this can be a hostname or IP Address
If you log in to this server for the first time you will get a security alert regarding server fingerprint. If you are sure that you're connecting to the right server you can click Yes
Input your username and password to log in.
Connecting to a Windows server
Login from Windows
- Click the Start button.
- Click Run… or press Win+R
- Type “mstsc” and press the Enter key.
- Type in the IP address of your server
- Click Connect.
- If all goes well, you will see the Windows login prompt.
