No need for nmap and other advanced tools when you can simply tell 
with telnet and netstat. When you are on that machine try 

telnet localhost 22

and you should get a response like
Connected to localhost.
Escape character is '^]'.

telnet from other host to trouble machine should get similar response.

ssh configuration is all in /etc/ssh You need to make sure sshd is 
running and if so try telnet test as mentioned above.

netstat -at
will tell you which ports the machine is listening to. Needless to say, 
ssh needs to be among them. There should be a line like:

tcp        0      0 *:ssh   *:*  LISTEN

Also, make sure that the configuration for ssh daemon is correct, i.e. 
the keys for the server were generated and stored in /etc/ssh. File 
names are like ssh_host_dsa_key
