If you are getting Unknown Host, This either means that
1. Host name that you have provided is Invalid.
2. DNS is not configured.
3. There might be some problem in the network
4. or the Host which you want to access is down.
Try to Ping the host.
And by looking the command that you have provided "ftp. ftp.umass.edu", here there is a problem - ftp followed by dot(.), but this will not give UNKNOWN HOST; indeed it will give "Command not found". So I assume that you are issuing the command correctly.
