ssh authoized keys nfs
Hi all
I would like to do ssh from machine "ub0" to another machine "ub1" without using passwords.
I setup using nfs on "ub0" but still I am asked to insert a password.

Here is my scenario:
* machine ub0 and ub1 have the same user "mpiu", with same pwd, same userid, and same group id
* the 2 servers are sharing a folder that is the HOME directory for "mpiu"
* I did a chmod 700 on the .ssh
* I created a key using ssh-keygene -t dsa
* I did "cat id_dsa.pub >> authorized_keys". On this last file I tried also chmod 600 and chmod 640
* off course I can guarantee that on machine ub1 the user "shared_user" can see the same fodler that wes mounted with no problem.

After all of this calling wathever function "ssh ub1 hostname" I am requested my password.
Do you know what I can try?

I also UNcommented in the ssh_config file for both machines
this line
Code:
IdentityFile ~/.ssh/id_dsa

I also tried

Code:
ssh -i $HOME/.ssh/id_dsa mpiu@ub1


Below the ssh -vv
