A ver si alguien me ayuda.
Estoy intentando configurar mi ordenador como servidor SSH para poder toquetear cuando no estoy en casa.
Este es mi sshd
# $OpenBSD: sshd_config,v 1.82 2010/09/06 17:10:19 naddy 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 change a
# default value.
Port 200
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
# The default requires explicit activation of protocol 1
Protocol 2
# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
# Lifetime and size of ephemeral version 1 server key
#KeyRegenerationInterval 1h
#ServerKeyBits 1024

# obsoletes QuietMode and FascistLogging
#SyslogFacility AUTH
#LogLevel INFO

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

#RSAAuthentication yes

#AuthorizedKeysFile .ssh/authorized_keys
# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#RhostsRSAAuthentication no
# similar for protocol version 2
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and 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 yes
#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'.

Tengo configurado el puerto 200, asi que en mi router he asociado el puerto 200 del NAT a la IP de mi pc (192.168.1.131) también al puerto 200.
Server Name External Port Start External Port End Protocol Internal Port Start Internal Port End Server IP Address Remove
Secure Shell Server (SSH) 200 200 TCP 200 200 192.168.1.131
Inicio el demonio y hago un
[carlos@carlos-pc ~][ $ ssh 192.168.1.131 -p 200
carlos@192.168.1.131's password:
Last login: Tue Mar 22 19:25:04 2011 from 192.168.1.131
[carlos@carlos-pc ~]$
Funciona pero ahora viene la miga, si hago un
[carlos@carlos-pc ~][ $ ssh XX.XX.XX.XX -p 200
ssh: connect to host XX. XX.XX.XX port 200: Connection refused
(Las XX son mi IP pública de internet) el cabrón no conecta. No hay manera. Ya sea por aquí o por el seudónimo que tengo por dyndns.
Mi hosts.allow es:
#
# /etc/hosts.allow
#
sshd: ALL
# End of file
Y el hosts.deny
#
# /etc/hosts.deny
#
ALL: ALL
# End of file
Por qué rechaza la conexion?
He hecho un
[carlos@carlos-pc ~][ $ sudo netstat -tnlp | grep ssh
tcp 0 0 0.0.0.0:200 0.0.0.0:* LISTEN 6947/sshd
Está todo correcto?
No tengo iptables instalado, digamos que está "por defecto" de la instalación de Arch.
Gracias!
