When I dont know for sure, I just run a scan against it. There are several out there, like NMAP, etc, but they are easy to use. Keep those firewalls secure. Below, you see me trying to determine if SSH is open or not, using NMAP via CLI.
In CLI, this is what I did. For a closed SSH port:
-------------------------------------------------------------------------------------------
C:\NMAP\nmap-6.40-win32\nmap-6.40>nmap -p 22 5.5.5.5
Starting Nmap 6.40 ( http://nmap.org ) at 2014-03-18 09:53 Central Daylight Time
Nmap scan report for 5.5.5.5
Host is up (0.0059s latency).
PORT STATE SERVICE
22/tcp closed ssh
Nmap done: 1 IP address (1 host up) scanned in 2.08 seconds
-------------------------------------------------------------------------------------------
For an open SSH port:
-------------------------------------------------------------------------------------------
C:\NMAP\nmap-6.40-win32\nmap-6.40>nmap -p 22 97.97.97.97
Starting Nmap 6.40 ( http://nmap.org ) at 2014-03-18 09:56 Central Daylight Time
Nmap scan report for 97.97.97.97
Host is up (0.0046s latency).
PORT STATE SERVICE
22/tcp open ssh
Nmap done: 1 IP address (1 host up) scanned in 2.18 seconds
C:\NMAP\nmap-6.40-win32\nmap-6.40>
-------------------------------------------------------------------------------------------
