ssh: connect to host 127.0.0.1 port 22: Connection refused

[freeneutron]

General system: Ubuntu 14.04
Guest system: Centos 6
Attempt to connect via ssh as end:

freeneutron@freeneutron-A780L3L:~$ ssh 127.0.0.1
ssh: connect to host 127.0.0.1 port 22: Connection refused

[freeneutron]

port 22 was forwarded in accordance with instructions

Ports below 1024 can not be forwarded on a Linux host. Also the guest needs to have ssh available and properly configured for it to work. CentOS has firewall rules to prevent it by default.

I replaced the port 22 to 2222. And it worked immediately.
Thank you very much for your help!
