scp command and no response

I should trasfer some files by xxx.xxx.xxx.xxx to local host.
In order to check the function works i tried to transfer a single file and I typed:

scp -P 21 username@xxx.xxx.xxx.xxx:/filename.nas /filename.nas

At this point i haven't response anch i have to type CTRL+C to return to console.

Can you help me?

Add the -v option to display debug informations

scp -v -P 21 username@xxx.xxx.xxx.xxx:/filename.nas /filename.nas
