Thank you for you answer,

I use a rsa key, so I adapt the command:


scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key
$ scp -o PubkeyAuthentication=no id_rsa.pub scettou@10.4.15.5:tempKey
scettou@10.4.15.5's password:
id_rsa.pub                                    100%  225     0.2KB/s   00:00

scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key
$ ssh -o PubkeyAuthentication=no scettou@10.4.15.5
scettou@10.4.15.5's password:
Last login: Tue Dec 22 13:06:30 2009 from scbsprod.servcenterxa.ch

scettou@SCBSPROD ~
$ cat tempKey >> .ssh/authorized_keys

scettou@SCBSPROD ~
$ exit
logout
Connection to 10.4.15.5 closed.

scettou@CHWS0018 /cygdrive/c/Documents and Settings/scettou/Desktop/key
$ ssh scettou@10.4.15.5
Connection closed by 10.4.15.5

So....what I can do?
