"Access denied" when trying to login into a Linux Fedora Server by using PuTTY

Don't worry if you receive "Access denied" when trying to login into your new Linux Fedora Server by using PuTTY.
Release 0.61 shows this message when GSSAPI authentication fails:it is the first method PuTTY tries. Although this, you will be able to login, if any other method of authentication works successfully.
New PuTTY releases corrected that (newest release is 0.63 at July 18, 2014)

ssh connect to host port 22 Connection refused

After installing Fedora-Live-Desktop-i686-20-1, I could not login because sshd deamon was not running.

[root@merope sysconfig]# ssh eider@thanatos
ssh: connect to host thanatos port 22: Connection refused
[root@merope sysconfig]#

Just start it by using "service sshd start" and everything works fine:
