authentication

[Julien VARLET]

I have some problems while authentication.
 
I created RSA keys and placed the public key on the remote host.
 
With the user toto, I have the following command line :
rsync --arvz --rsh=ssh Nouveaudossier
essai_ftp at 192.168.1.4:/home/essai_ftp/test/
<mailto:essai_ftp at 192.168.1.4:/home/essai_ftp/test/> 
but it tells the password of essai_ftp.
 
So I added this :
--password-file=password.txt
 
but it does not change anything.
 
 
I would like not to give password.
 
Can you help me please ?
