How to upgrade OpenSSH 7.0 to 7.2 on a OpenBSD Unix and Linux

To upgrade OpenSSH, a popular open-source implementation of the Secure Shell (SSH) protocol, from version 7.0 to 7.2 on OpenBSD and other Unix-like systems, follow these steps:

1. Check the version of OpenSSH that is currently installed on your system by running the following command:

ssh -V

This will display the version of OpenSSH that is currently installed.

2. Check the version of OpenSSH that is available for installation by running the following command:

pkg_info -Q openssh

This will display a list of available versions of OpenSSH that can be installed on your system.

3. If the version of OpenSSH that is available for installation is newer than the version that is currently installed, upgrade OpenSSH by running the following command:

pkg_add openssh

This will upgrade OpenSSH and any dependencies required.

4. To verify that the upgrade was successful, run the following command:

ssh -V

This will display the version of OpenSSH that was installed.

5. Restart the ssh service by running the following command:

systemctl restart ssh

This will apply the changes made by the upgrade.

That's it! OpenSSH is now upgraded to the latest version on your OpenBSD or other Unix-like system. Please note that the exact commands and procedures for upgrading OpenSSH may vary depending on the specific version of OpenSSH and the operating system that you are using.
