OpenSSH is included in a default Fedora installation, unless manually excluded. To confirm that you already have it installed, run the rpm -qa | grep openssh command. The output shown here may differ slightly from your output:

$ rpm -qa | grep openssh

openssh-6.1p1-6.fc18.x86_64
openssh-server-6.1p1-6.fc18.x86_64
openssh-clients-6.1p1-6.fc18.x86_64

The above command queried the RPM package database and the output shows the OpenSSH RPM packages that are installed on the system. Run the ssh -V (upper-case 'V') command as another way to find out the installed version:

$ ssh -V

OpenSSH_6.1p1, OpenSSL 1.0.1e-fips 11 Feb 2013

If you do not have the openssh package installed, you can install it with the yum command. Perform the following command as the root user and follow the instructions to install openssh:

# yum install openssh
