i want to be able to execute some secured commands from windows to linux, like plink, psftp,...

windows
server name:rangiroa
user:administrateur

AIX
server name:java
user:fjaspart

linux
server name:rac2
user:fjaspart

public and private key are generate on windows with puttygen.
public key is send on an AIX and linux servers in this file:
vi /home/fjaspart/.ssh/authorized_keys2 (on AIX)
ssh-rsa AAAAB3NXQsZpeJm0S1[...]WqM4s= Administrateur@rangiroa

vi /home/fjaspart/.ssh/authorized_keys (on linux)
ssh-rsa AAAAB3NXQsZpeJm0S1[...]WqM4s= Administrateur@rangiroa

commands executed from windows:
C:\>plink.exe -ssh fjaspart@java date
jeu 21 jun 14:04:46 DFT 2007

C:\>plink.exe -ssh fjaspart@rac2 date
fjaspart@rac2's password:
jeu jun 21 14:03:11 CEST 2007

passwd is asked when i try this command to linux.
Rights on files and directory are the same on aix and linux.

i didn't understand why passwd is asked for linux

ssh commands works fine from aix to linux, linux to aix and linux to windows, no passwd is asked

thenk you for help

Check this link and make sure your permission atributes are correct using the chmod command mentioned. http://www.suso.org/docs/shell/ssh.sdf

thank you Brian,
permission attributes are good:

[root@RAC2 ~/.ssh]#ls -al
total 64
drwx------ 2 root root 4096 jun 22 08:59 .
drwxr-x--- 19 root root 4096 jun 22 08:59 ..
-rw------- 1 root root 662 jun 21 14:07 authorized_keys

ssh works fine from aix to linux and windows,
linux to aix and windows
windows to aix
but not from windows to linux.

i don't understand...!!!!!!!

i can bypass this pb with "-pw" option, but this is not very good...
