I got this error when trying to set SSH login on my user.

Feb  2 13:56:57 (none) sshd[4075]: debug1: trying public key file //.ssh/authorized_keys
Feb  2 13:56:57 (none) sshd[4075]: debug1: Could not open authorized keys '//.ssh/authorized_keys': Permission denied

The files permissions are:

drwxr-xr-x 4 root    root    4.0K Feb  2 12:08 ..

# and ChallengeResponseAuthentication to 'no'.
UsePAM no

I have done restart to the SSH service and to the machine.

I saw this post: SSHD Gives error could not open Authorized Keys, although permissions seem correct

The answer given there did not helped me. When I try to run restorecon -FRvv ~/.ssh I get:

root@(none):/home/soinfit/.ssh# restorecon -FRvv ~/.ssh
-bash: restorecon: command not found

EDIT

root@(none):~# grep soinfit /etc/passwd
soinfit:x:1001:1001::/:/bin/sh

You have set the root directory / as home directory for the user soinfit instead of /home/soinfit.

Edit the entry in /etc/passwd for the user soinfit from 

soinfit:x:1001:1001::/:/bin/sh

to 

soinfit:x:1001:1001::/home/soinfit:/bin/sh

  • @BasileStarynkevitch The directory `.ssh` is located in `/home/soinfit` (see code befor 'EDIT' in OP). The original entry in `/etc/passwd` on the other side implyes that the user `soinfit` has `/` as `$HOME`. Therefor my suggested change of this entry in `/etc/passwd` – Sebastian Stigler Feb 02 '15 at 12:53
  • Now I got another error: Feb 2 15:33:59 (none) sshd[4440]: Failed publickey for soinfit from 79.182.124.164 port 49778 ssh2 Feb 2 15:33:59 (none) sshd[4440]: debug3: mm_answer_keyallowed: key 0x7f8d56455f70 is not allowed – dasdasd Feb 02 '15 at 13:39
  • Looks like the public key from the location you call `ssh soinfit@79.182.124.164` is not in the `/home/soinfit/.ssh/authorized_keys` on your server. – Sebastian Stigler Feb 02 '15 at 13:48
  • The file is there. Im sure about it. – dasdasd Feb 02 '15 at 14:01
  • But is the entry of the `id_rsa.pub` file from the location you starts the ssh connection in the file `/home/soinfit/.ssh/authorized_keys` (it should be a line like: `ssh-rsa AAAAB3[.......]== some_comment`) – Sebastian Stigler Feb 02 '15 at 14:18
