SSH (Secure Shell) is a protocol that enables access to devices or servers in another presentation on the network such as
rlogin. Telnet and
rloginprovide connections without encrypting connections, including user passwords, while SSH encrypts all connections with a strong crypto method. For this reason, it is the most preferred method.
In this article, we will see how to install SSH on a machine running Ubuntu operating system.
- First, you will need to download and install the
openssh-serverpackage. To do this,
sudo apt-get install openssh-server
We do the above command with the help of
sudo in ubuntu. Sudo one-on-one also provides root authority. Since Sudo is written, it will request the user password of our ubuntu account.
The upload is finished. You can now access this machine from a Linux or Unix machine, or from a Windows computer.
How to Connect SSH from Linux / Unix Operating Systems
Ssh username@ipaddress values must be written correctly from the command line. For example, ssh email@example.com. In the meantime, you can find out the IP address of a machine in Linux or Unix operating systems with the
ifconfig command (equivalent to
ipconfig in Windows). When you apply the ssh username@ipadresi command, you will be asked for the password of the user account specified with username on the Linux machine at the specified IP address. When the password is typed correctly, the connection is provided.
Here we will see how to install Ubuntu 14.04 / 16.04 LTS / 18.04 LTS.
We use the command below to load putty into Ubuntu.
$ sudo apt-get install putty -y
An alternate way to install putty is via GUI ( Synaptic Package Manager), In case Synaptic is not installed the first install it via below command,
$ sudo apt-get install synaptic -y
After installing Synaptic Package Manager, we search and find putty from the window that opens.
After the Putty connection is provided, we will need to enter the IP address and port of the server to which we will connect. Then, we enter the username and password and connect to the server.
