1) Install Openssh-server
# yum Install Openssh-server
2) Check to see if the Openssh-server has been successfully installed
# Rpm-qa | grep openssh-server
3) Modify the SSH service configuration file (need to change under the root user)
Open/etc/ssh/2,1 in front of the # number.
4) and then restart SSH
# Service Sshd Restart
5) Configure boot automatically start SSH service
# vi/etc/rc.local Join
6) About the firewall problem simply do not consider security directly shut down. (Again I use FEDORA20, other version of the firewall is not here to elaborate)
# Systemctl Stop Firewalld.service
Then you can use SSH Secure Shell client to access your Linux (FEDORA20).
Here again, about the Fedora firewall problem, if you have to know how to modify the FEDORA20 firewall, let its designated port through the large, you can advise.
And I'm here to cite someone else's blog, I just want to tidy up the idea. A step-by-step study of Linux is not offensive.
