Bonjour.
J’ai installé firestarter récemment parce que je n’avais pas de firewall sur mon portable.
Quand je démarre mon ordi je vois passer rapidement dans la procédure de lancement un …firewall… [failed]. J’essaie de le retrouver dans dmesg en utilisant le commande
mais ça ne me sort rien à propos du firewall ou de firestarter.
De ce fait je me demande si firestarter se lance correctement au démarrage. Comment faire pour le savoir ? J’imagine qu’il y a un démon ou un processus qui doit tourner mais :
# ps aux | grep fire
root 163 0.0 0.0 0 0 ? S< 15:31 0:00 [firewire]
root 4722 0.0 0.0 7848 876 pts/0 S+ 15:46 0:00 grep fire
Toutefois, après démarrage de l’ordi et sans rien toucher :
[code]# iptables -L

[/code]
Ceci me laisse penser que le firewall est activé parce que si je stoppe firestarter :
[code]# /etc/init.d/firestarter stop
[ ok ] Stopping the Firestarter firewall…
root@pascal:/home/laguespa# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination[/code]
Bref, ce qui m’intéresserait c’est d’avoir accès à ce message que je n’ai pas le temps de lire au lancement de ma machine et dont je ne trouve aucune trace dans dmesg et de savoir comment je fais pour vérifier que firestarter est actif.
