Hi,

My first post to this list....after googling the web to find the
solution.

I have 2 box. One running Redhat (OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19
2003) and other Ubuntu(OpenSSH_4.6p1 Debian-5build1, OpenSSL 0.9.8e 23
Feb 2007).

I am trying to do password less login _from_ redhat _to_ ubuntu box. It
works for different user ID, but not for same user id.

i.e If user_A@redhat ssh's to user_B@ubuntu, it works.

But when, user_A@redhat ssh'd to user_A@ubuntu, it doesn't work.

PS: Home directory is common across box. (NIS ID's)

---log ---
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/dilipm/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/dilipm/.ssh/id_rsa.
Your public key has been saved in /home/dilipm/.ssh/id_rsa.pub.
The key fingerprint is:
d4:db:36:3a:dd:9e:6d:c0:31:4a:75:d9:b9:9d:9d:c2 dilipm@blrmputest1

$cat id_rsa.pub >> authorized_keys

You are doing it on a server, right?

Yes. But both are running different versions

I usually perform next steps to setup a passwordless login (all
commands done on a client side, that is where you are connecting from,
in your case "user" is the same that you are logged in on a client):

$ ssh-keygen -t dsa -N '' -b 1024

$ ssh-copy-id -i ~/.ssh/id_dsa.pub user@remotebox

In case there is no ssh-copy-id (for example, an older box) I use
next: cat ~/.ssh/id_dsa.pub | ssh user@remotebox "cat >>
~/.ssh/authorized_keys"

Testing:

$ ssh user@remotebox

I did it and it is not working. Also the .ssh folder permissions are,
It is going till...

debug1: Offering public key: /home/dilipm/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password
debug1: Offering public key: /home/dilipm/.ssh/id_dsa
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: password

Don't know why the password is not accepted.
