Xchat et DCC
Bonjour,
J'ai un petit problème avec Xchat (1.8.9 et 2.0.4): j'arrive à envoyer
des fichiers mais impossible d'en recevoir. Chaque fois j'ai un message
"connection time outé", même lorsque j'accepte le fichier immédiatement
ou que j'active l'acceptation automatique des fichiers.
ip_conntrack_irc est compilé en module et il est chargé au démarrage de
la machine.
Ci-joint les règles iptables de ma machine.
Si une bonne âme pouvait me donner un coup de main, ça serait sympa car
je n'ai rien trouvé sur le net.
Merci à vous.
