Salut, j'utilise Mandrake Linux 8.2 sur un vieux Pentium 90, que je voudrais utiliser comme firewall pour mon poste Windows lorsque je suis sur internet.
J'ai configur� l'IP-forwarding et le partage de la connexion internet fonctionne. Cependant, je n'arrive pas � maintenir la connexion en vie (alors qu'il n'y a aucun probl�me du genre lorsque je me branche � partir de mon poste Windows sur internet). La connexion la plus longue n'a dur� qu'1 heure et quart! J'ai essay� 2 trucs pour essayer d'y rem�dier: 1) ping -i60 194.154.192.101 (je pinge le serveur DNS de mon FAI toutes les 60 secondes) 2) j'ajoute "lcp-echo-interval 60" dans /etc/ppp/options (demande de reponse du serveur de mon FAI toutes les 60 secondes). Sans succ�s! Voici mes fichiers de configuration: /etc/host.conf order hosts,bind multi on /etc/hosts 127.0.0.1 localhost.localdomain localhost 192.168.0.1 pentium.home.lu pentium 192.168.0.2 athlon-tb.home.lu athlon tb /etc/resolv.conf search home.lu pt.lu nameserver 192.168.0.1 /etc/ppp/options noauth crtscts lock modem defaultroute ipcp-accept-local ipcp-accept-remote usepeerdns /etc/sysconfig/network NETWORKING=yes FORWARD_IPV4=yes HOSTNAME=pentium.home.lu DOMAINNAME=home.lu GATEWAY="192.154.192.100" (l'adresse pour le GATEWAY m'a �t� indiqu�e par mon FAI. J'ai aussi essay� sans indiquer de GATEWAY, mais sans plus de succ�s) Finalement, si �a peut aider, voici un extrait de mon logfile (/var/log/messages): Apr 13 10:16:15 pentium pppd[5130]: pppd 2.4.1 started by alex, uid 501 Apr 13 10:16:16 pentium chat[5131]: abort on (BUSY) Apr 13 10:16:16 pentium chat[5131]: abort on (NO CARRIER) Apr 13 10:16:16 pentium chat[5131]: abort on (VOICE) Apr 13 10:16:16 pentium chat[5131]: abort on (NO DIALTONE) Apr 13 10:16:16 pentium chat[5131]: abort on (NO ANSWER) Apr 13 10:16:16 pentium chat[5131]: send (ATB20^M) Apr 13 10:16:16 pentium chat[5131]: expect (OK) Apr 13 10:16:16 pentium chat[5131]: ^M Apr 13 10:16:16 pentium chat[5131]: OK Apr 13 10:16:16 pentium chat[5131]: -- got it Apr 13 10:16:16 pentium chat[5131]: send (ATDT90070705^M) Apr 13 10:16:16 pentium chat[5131]: expect (CONNECT) Apr 13 10:16:16 pentium chat[5131]: ^M Apr 13 10:16:17 pentium chat[5131]: ^M Apr 13 10:16:17 pentium chat[5131]: CONNECT Apr 13 10:16:17 pentium chat[5131]: -- got it Apr 13 10:16:17 pentium chat[5131]: send (\d) Apr 13 10:16:18 pentium pppd[5130]: Serial connection established.
