Re: Problem with ssh keys


Thanks Larry.....

Setting up Cygwin with smbntsec solves the problem, and i could 
autenticate my keys through my net.

But then, i delete the keys to remake all the process, generating new 
keys for others users just as i did, the 
thing just not go too good.

I believe its because the drives with the HOME´s are mounted as the 
administrator owner, and some kind of damage happens when i change 
variable CYGWIN, look:

pcosta@pcdep06 ~
$ ls -la
total 3619
drwx------+   1 ???????? ????????        0 Feb  3 15:08 .
dr-xr-xr-x    8 0        0               0 Dec 31  1969 ..
-rwxr-xr-x    1 pcosta   Nenhum        533 Feb  3 15:08 .bash_profile
-rwxr-xr-x    1 pcosta   Nenhum       1131 Feb  3 15:08 .bashrc
-rwx------    1 Administ ????????      221 Dec 13  2001 .rhosts
drwx------+   1 pcosta   Nenhum          0 Feb  3 15:02 .ssh
-rwx------    1 Administ ????????    63488 Jun 21  2002 Fluxograma_MAI.vsd
-rwx------    1 Administ ????????    94314 Nov 25  2002 Fluxograma_MAI.wmf

-rwx------    1 Administ ????????      600 Sep 15 16:42 PUTTY.RND

Look what happens, if i try to generate the keys:
pcosta@pcdep06 ~
$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (//pcdep41/home/pcosta/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open //pcdep41/home/pcosta/.ssh/id_dsa failed: Permission denied.
Saving the key failed: //pcdep41/home/pcosta/.ssh/id_dsa.

Well, in my passwd seems to be correct, e.g, i don´t mount manually my 
home drive:

My variables are now:

CYGWIN   smbntsec tty
CYGWIN32 smbntsec tty


Is there a explicit way to tell Cygwin that i am owner of my drive???


Thanks in advance....
