Probleme Connexion ADSL - réseaux et sécurité - Linux et OS Alternatifs

hé hé ca ne fonctionne pas :/
 
Bon j'ai deja une connexion adsl qui tourne sur unr RH (P100) depuis + de 1 an.
 
Je veux virer le P100 et me servier d'un P3 450 + debian SID.
Mais ca ne fonctionne pas :'(
 
J'utilise rp-pppoe.
 
mon systéme reconnait mes 2 cartes réseau  
 
 

Code :
  1. donald:/# ifconfig

voici ma table de routage :
 
 

Code :
  1. Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
  2. localnet        *               255.255.255.0   U     0      0        0 eth0
  3. default         donald          0.0.0.0         UG    0      0        0 eth0

 
 
A noter que j'arrive a recuperer une ip, mais apres je rien du tout, meme pas un ping (ip ou nom)
 
Merci de m'aider

# Make the PPPoE connection your default route.  Set to

    DEFAULTROUTE=no
 
faudrait peut etre mettre ca a yes histoire que tu es la bonne route par defaut (soit ppp0 et l'ip associée)

Voila mon fichier
 
shadowland:/etc/ppp/peers# cat dsl-provider
 
# Configuration file for PPP, using PPP over Ethernet  
# to connect to a DSL provider.
#
# See the manual page pppd(8) for information on all the options.
 
##
# Section 1
#
# Stuff to configure...
 
# MUST CHANGE: Uncomment the following line, replacing the user@provider.net
# by the DSL user name given to your by your DSL provider.
# (There should be a matching entry in /etc/ppp/pap-secrets with the password.)
user pwet
 
# Use the pppoe program to send the ppp packets over the Ethernet link
# This line should work fine if this computer is the only one accessing
# the Internet through this DSL connection. This is the right line to use
# for most people.
pty "/usr/sbin/pppoe -I eth1 -T 80 -m 1452"
 
# If the computer connected to the Internet using pppoe is not being used
# by other computers as a gateway to the Internet, you can try the following
# line instead, for a small gain in speed:
#pty "pppoe -I eth1 -T 80"
 
# An even more conservative version of the previous line, if things
# don't work using -m 1452...  
#pty "pppoe -I eth1 -T 80 -m 1412"
 
 
# The following two options should work fine for most DSL users.
 
# Assumes that your IP address is allocated dynamically
# by your DSL provider...
noipdefault
# Comment out if you already have the correct default route installed
defaultroute
 
##
# Section 2
#
# Uncomment if your DSL provider charges by minute connected
# and you want to use demand-dialing.  
#
# Disconnect after 300 seconds (5 minutes) of idle time.
 
#demand
#idle 300
 
##
# Section 3
#
# You shouldn't need to change these options...
 
hide-password
lcp-echo-interval 20
lcp-echo-failure 3
# Override any connect script that may have been set in /etc/ppp/options.
connect /bin/true
noauth
persist
mtu 1492
maxfail 0
 
 
Mais visiblement, on ne doit pas utiliser la meme chose...
 
Tu l'as installé comment rp-pppoe ? Par apt-get install pppoe ?
 
Bonne méthode Debian :
 
apt-get install pppoe pppoeconf
 
lancé pppoconf et voila

je crois me souvenir de devoir ajouter une route mais je ne sais plus laquelle :'(
 
une idée ?

Reply

Marsh Posté le 11-05-2003 à 14:13:53    

j'ai oublié, tu sembles avoir deja une route par defaut et c'est mal car pppd ne sait pas la remplacer. Il faut que tu vires ta route par defaut, elle sera ajoutée automatiquement par pppd a la connexion;

je viens de trouver et ca fonctionne :)
 
 route del default gw `route -n|awk '$1=="0.0.0.0" {print $2}'|head -1`
route add default gw `ifconfig ppp0|grep "P-t-P"|awk '{print $3}'|cut -d ':' -f 2`

je ne vois pas trop pq tu as besoin d'un tel script mais bon, tant mieux si ca marche.
 
Regarde plutot dans /etc/network/interfaces si tu n'as pas une route par defaut de definie, vire la sio necessaire et laisse l'option defaultroute a yes dans ton fichier de pppoe
