INSTALL OPENSSH UBUNTU 20.04 HOW TO
How to do that? You can try to connect to the openssh server from your localhost through your openssh client or do a portscan with nmap, but I like to use a small tool called netcat, also known as the TCP/ IP Swiss army knife. How Do I Connect to OpenSSHīefore we go further, we need to verify if our openssh server is working or not. $ sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.original_copyĪs you can see from the command I typed, I added the original_copy suffix, so every time I see this file I know it is an original copy of the sshd config file. Open a terminal and run the following command to make a copy of the original sshd configuration file. It’s time to configure our OpenSSH behaviour through the ssh config file, but before editing the /etc/ssh/sshd_config file we need to backup a copy of it, so in case we make any mistake we have the original copy.

Strong Authentication ( Public Key, One-Time Password and Kerberos Authentication).Port Forwarding (encrypted channels for legacy protocols).X11 Forwarding (encrypt X Window System traffic).Strong Encryption ( 3DES, Blowfish, AES, Arcfour).If a third party tries to intercept your connection, OpenSSH detects it and informs you about that. The most important reason why should use OpenSSH tools over ftp and telnet is that all communications and user credentials using OpenSSH are encrypted, they are also protected from man in the middle attacks. This version of OpenSSH comes with many new features and patches, so if you already use OpenSSH for administering your machines, I suggest you to do an upgrade. The latest version is OpenSSH 6.4 which has been released on November 8, 2013. A main factor which has made possible for OpenSSH to be used so much among system administrators is its multi-platform capability and very useful nice features it has. OpenSSH is developed by the Open BSD group and it is released under Simplified BSD License. Many people, new to computers and protocols, create a misconception about OpenSSH, they think it is a protocol, but it is not, it is a set of computer programs that use the ssh protocol. OpenSSH is a free open source set of computer tools used to provide secure and encrypted communication over a computer network by using the ssh protocol.

The one I will discuss in this article is ssh, a secure remote protocol which is used to work remotely on other machines or transfer data between computers using SCP (Secure Copy) command.
