Bonjour à tous,

petite precision je connais linux depuis moins de 6 mois pardonnez mes erreurs ou mon ignorance.

mon pb est que je n'arrive plus a me connecter en ssh a ma station via putty.

j'ai un poste sous gentoo 2007, je pouvais me connecter via putty en ssh.

j'ai voulu acceder a ma station depuis le web donc j'ai parametré sshd_config pour écouter a la fois sur le port 22 et le port 443 (pour traverser un proxy)
bon ça n'a pas marché, de retour a la maison, j'ai fais des tests en local ça ne marchait pas non plus donc j'ai fais machine arrière.

j'ai remis le fichier tel qu'il etait avant c'est dire comme ça

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

# Disable legacy (protocol version 1) support in the server for new
# installations. In future the default will change to require explicit

# Set this to 'yes' to enable PAM authentication, account processing,
