Bonjour,je suis un super noob sous linux.
J’ai un server dedie chez 1&1 pour ma team sur ofp.
Le server tourne avec un debian64.
Je me plaint en semoment de beacuoup de lag sur le server,et j’ai chercher un peux sur google et j’ai fait cette commande “netstat vla” pour voir se qui se connecter a mon server.
La réponse est la suivante:

Je pense que les premiers c’est moi connecter et les autres avec autant de port ouvert un petit malin.
Je voudrais savoir deja si je suis bien sur la bonne voi,que c’est bien un ptit **** qui me hack.
Donc en vu de ma deduction je je voudrais couper l’herbe sous le pied a se **** et configurer mon server de tel sorte a ne pas avoir d’autre chose de se genre.
J’ai commencer a suivre se tutos http://forum.debian-fr.org/viewtopic.php?t=1901 , mais arriver a cette ligne de commande /etc/init.d/mon_parefeu clean j’ai pas mal d’error qui se montre

Je suis complement dans le floux la,même super degouter car un ** attaque toujours des personne qui si connaisse le moin.
Je suis pret à réinitialiser le server pour reprendre les bases,mais je sais pas trop.
Si quelqu’un pouvais m’aider se serais vraiment très gentil.
Merci.
