No SSH connectivity

If you've just installed a Red Hat (or Fedora) system and you find that even though the ssh daemon is running and you're very sure there's no firewall blocking your access, that you still are unable to ssh or telnet to the system, then you may have run into to firewall that gets installed with Red Hat (or Fedora).

A very easy way to flush all rules from that firewall can be done by running:

# iptables -F
Now check again if you access your system through ssh and/or telnet.
