disabling firewall on Fedora

[narayans]

I installed Fedora 16 on a new machine.
I also installed ssh.

service ssh status
Redirecting to /bin/systemctl  status ssh.service
ssh.service
	  Loaded: error (Reason: No such file or directory)
	  Active: inactive (dead)

and

 ps -el | grep ssh
4 S     0 31912     1  0  80   0 - 18847 poll_s ?        00:00:00 sshd
4 S     0 32106 31912  0  80   0 - 32003 poll_s ?        00:00:00 sshd

I can ping to machine in question but can not login via ssh.Unless I disable the firewall via
system-config-firewall.
ssh there is marked in trusted services list.So what more do I need to check in on Fedora 16?
