Contrer une attaque DDOS sur un serveur OVH sous linux, sous release 3 OVH ...
1/ Connectez vous en ssh sur votre serveur
ssh -l root adresse_ip_du_serveur
> saisir mot de passe root
> saisir mot de passe root
2/ Désactiver serveur web apache
/etc/init.d/httpd stop
3/ Editez les derniers logs pour voir la classe d'ip qui vous attaque
cd /var/log/httpd
nano access_log
3 bis/ netstat -na peut également afficher la classe d'ip qui vous attaque si apache tourne
4/ Bannir classe d'ip attaquante
Lorsque vous avez localisé la classe d'ip x,y,z,1 to x,y,z,254 il suffit de la bannir
Copiez simplement les commandes suivantes:
