Remember the permissions for .ssh

I had a weid experience. All of a sudden I wasn't able to login on my NAS with ssh. I use PKI (RSA) for login and have disabled pure password login. A `ssh -v revealed:

1debug1: Authentications that can continue: publickey
23 times.

First I thought that the keys didn't match - that was not it (I generated a new pair and installed them - same result).

Then I remembered that sshd is really picky with the permissions on the directories. If the private key in .ssh is accessible by others than the user, it will by default fail.

That was it. :-) Now I just need to find out why the permissions has changed...
