Thanks Ken and Jeremy
I took the default, it went on without error, and at last I could start my
sshd service on windows 7 without immediate abortion.
As a first test I issued a scp command from the freebsd server as follows
(first, login and second scp command asking to transfer "testfile.txt" from
the windows computer at 192.168.1.103 to the freenas server.

$ssh gabriel AT freennas
Password etc... Welcome... OK
$scp gabriel AT 192 DOT 168 DOT 1 DOT 103:/cygdrive/E/gabriel/testfile.txt 
~/gabriel/testfile.txt

Now the connection is established but there is a password problem

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password,keyboard-interactive).

The 2 users who communicate have the same name gabriel and the same
password, but this password is denied. Is this a known problem  and how can
I debug it.
