Bonjour,
je me permets d'intervenir sur ce forum car depuis deux jours j'ai de gros ralentissements de connexion depuis mon navigateur lorsque je navigue sur le net, il charge pendant un temps fou et parfois la page ne s'affiche même pas. J'ai ce problème que depuis mon pc. J'ai utilisé la commande netstat -a et j'obtiens :
fzer@fzer:~$ netstat -a
Connexions Internet actives (serveurs et établies)
Proto Recv-Q Send-Q Adresse locale Adresse distante Etat

J'aurais aimé savoir ce que " localhost:tproxy " veut dire , s'il vous plaît ? Je n'ai pas de proxy et j'en utilise pas.
D'autre part en utilisant iptables j'obtiens ceci :
root@frez:/dev# sudo iptables -L -v
