Mmmm... le contenu a l'air différent, mais l'un des deux ne serait il pas en trop ?
Quoi qu'il en soit, lorsque je lance | Code: | | /etc/init.d/sshd start |
ça marche,
chouette !
mais au bout d'une dizaine de minutes, j'obtiens un timeout...
j'ai modifié certaines options de /etc/ssh/sshd_config :
| Code: |
TCPKeepAlive yes
# [...]
ClientAliveInterval 0
ClientAliveCountMax 99
|
Mais ces valeurs ne semblent pas bonnes et j'aimerais bien savoir quoi mettre...

J'ai laissé en commentaires les 3 paramètres que tu cites.
Je n'ai pour ma part aucun problème de timeout en ssh.
Est-ce que tes timeout ont lieu uniquement en periode d'inactivité sur ta console ssh ou cela a lieu tout le temps ?

seulement en période d'inactivité,
à noter que j'utilise putty sur un poste Windows au travail pour accéder à ma machine linux à la maison.
voilà mon sshd_config en entier :
| Code: |
courgette ssh # cat sshd_config

# 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.

Voila le mien. J'ai noté quelques différences.
J'utilise aussi putty pour accéder à ma gentoo.
Good luck

Je remarque que chez toi le "protocole 2" est commenté.
Donc tu dois utiliser une ancienne version du protocole ssh et moi une nouvelle.
C'est peut-être une différence importante.
Sinon j'ai regardé brièvement le contenu de /etc/sshd2_config
mais j'y ai pas trouvé mon bonheur...
Je suis un peu perdu parmi ces configs ssh, personne d'autres n'aurait déjà roulé sa bosse sur le sujet par hasard ?

C'est pas un paramètre générique lié au terminal de la machine sur laquelle tu te connectes, plutot?
Si t'as la possibilité de vérifier si ça fait pareil en local, ou bien si quelqu'un qui connait le paramètrage en question...

J'avais ca a cause du firewall de mon routeur...
Donc j'ai mis ma gentoo en DMZ et utilisé iptables à la place  |
