Comando ssh de Windows a Mac: permiso denegado

1

Objetivo

Quiero acceder a mi computadora Mac local (versión: High Sierra 10.13.5) desde mi computadora Windows (Windows 10). El propósito es la automatización, eliminar la autenticación de contraseña y agregar acceso de claves SSH. Ambas máquinas están en el mismo Wi-Fi.

Configuración Mac

Aquí está mi archivo sshd_config:

#   $OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
#HostKey /etc/ssh/ssh_host_ed25519_key

# Ciphers and keying
#RekeyLimit default none

# Logging
#SyslogFacility AUTH
#LogLevel INFO

# Authentication:

#LoginGraceTime 2m
#PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

#PubkeyAuthentication no

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile  .ssh/authorized_keys

#AuthorizedPrincipalsFile none

#AuthorizedKeysCommand none
#AuthorizedKeysCommandUser nobody

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
#IgnoreRhosts yes

# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication no
#PermitEmptyPasswords no

# Change to no to disable s/key passwords
ChallengeResponseAuthentication no

# Kerberos options
#KerberosAuthentication no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes
#KerberosGetAFSToken no

# GSSAPI options
#GSSAPIAuthentication no
#GSSAPICleanupCredentials yes

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.

Aquí está mi carpeta .ssh en Mac:

User$ ls -a
.       ..      id_rsa      id_rsa.pub  known_hosts

Configuración de Windows

Aquí está mi carpeta .ssh en mi computadora con Windows:

Répertoire de C:\Users\myName\.ssh

28/06/2018  20:13    <DIR>          .
28/06/2018  20:13    <DIR>          ..
28/06/2018  20:28             1 679 id_rsa
28/06/2018  20:28               397 id_rsa.pub
28/06/2018  21:17             1 608 known_hosts

Llaves

He generado las claves SSH en mis computadoras Windows y Mac para generar las carpetas, luego copié la clave pública ".pub" de Windows a la Mac /.ssh/id_rsa.pub

Pasos Intentados

Ejecuté esto en Windows:

C:\Users\myName>ssh [email protected] -vvv

y esta fue la salida:

Estoy un poco perdido en los pasos que me he perdido.

Como está accediendo a la Mac desde Windows, necesita la clave privada en el sistema Windows y la clave pública en la Mac. La clave pública se coloca en un archivo llamado certified_keys en el host al que se envía (en este caso, la Mac). Estaría ubicado en:

~/.ssh/authorized_keys 

Este archivo contiene las claves públicas para los clientes desde los que se conectará.

Asegúrese de establecer los permisos en el archivo usando chmod go-rwx authorised_keys. Si es legible por otros que no sean el propietario, creo que ssh no procesará el archivo.

La pregunta dice "He generado las claves SSH en mis computadoras Windows y Mac para generar las carpetas, luego copié la clave pública" .pub "de Windows a la Mac". Entonces parece que estás sugiriendo algo que el OP ya ha hecho.
Scott
El detalle proporcionado no estaba claro sobre dónde se colocaron las llaves. Parecía que se crearon dos conjuntos diferentes de claves en las dos computadoras. La clave privada en este caso permanecería en Windows y la parte pública se colocaría en la Mac remota en el archivo indicado.
Hogstrom
@Hogstrom Creo claves en windows y mac para asegurarme de que se crearán carpetas, luego copié la clave pública de (windows) al id_rsa.pub. Pero la clave privada de Windows permanece en las ventanas
M1n1M1n1ng
Lo que falta es copiar la clave pública en la Mac y ponerla en un archivo llamado certified_keys . Este archivo contiene una línea para cada clave pública que procesará
Hogstrom
Hola, sí, fue el paso que faltaba. ahora funciona !! Gracias a todos
