iro

signatures non valides [resolu]

Bonsoir,

Il y a quelques jours il m’était impossible de faire les mises a jour, que se soit par le gestionnaire ou par synaptic.

En regardant le man de apt-get, j'ai tape plusieurs commandes (du coup ça refonctionne) mais en tapant sudo apt-get update j'ai vu ça:

W: Erreur de GPG : http://ppa.launchpad.net precise Release : Les signatures suivantes ne sont pas valables : BADSIG 6AF0E1940624A220 Launchpad PPA for TualatriX
W: Erreur de GPG : http://archive.canonical.com oneiric Release : Les signatures suivantes ne sont pas valables : BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>

nmap me dit que tous les ports de mon adresse sont bloque.

Quand au localhost: 53/tcp  open  domain        631/tcp open  ipp .(Je pense que ces 2 ports ouvert c'est normal, a confirmer.)

J'ai effectue les tests anti-rootkits qui non rien donnes a parement:

Re : signatures non valides [resolu]

Bonjour,

Pour les problèmes apt, jette un oeil sur cette page : probleme_apt

Pour les ports, le 53 doit être le DNS et le 631 c'est cups.

Quand au rapport rkhunter,

Suspect files: 1

le fichier unhide.rb est un faux positif, c'est un fichier légitime.
Pour ma part, je ne vois rien d'inquétant.

apt-get update me donne la même chose.

Je suspectai une intrusion: -paramètres qui changent sans raison
                                           -plusieurs malwares sur win (j'ai du reinstaller 2 fois en 4 mois mad ce qui m'a decide pour ubuntu)
Je suppose que le lamer a mon ip et mon mac.

Mais si vous pensez qu'il n'y a rien ...

Merci de me rassurer cool

Franchement à moins que tu fasses tourner plein de service du genre ssh, http, samba, lamp, etc sans un minimum de protection, que veux tu qu'il fasse avec ton ip et ton adresse mac??
Bon et j'ai supposé que tu es derriere un routeur dont tous les ports ne sont pas ouvert bien sûr.
Si tu veux plus de sécurité, active le pare-feu :

sudo ufw enable

la politique par defaut de UFW est de bloquer toutes les connexions entrantes, ensuite c'est assez simple à parametrer :
http://doc.ubuntu-fr.org/ufw
Si tu prefere avoir un interface graphique il existe un GUI :

sudo apt-get install gufw

http://doc.ubuntu-fr.org/gufw


Pour en revenir avec ton problème de gpg :

Apparemment tu n'arrive pas à télécharger la clef public des 2 dépôts, essaye :

sudo apt-key adv --recv-keys --keyserver hkp://subkeys.pgp.net 6AF0E1940624A220
sudo apt-key adv --recv-keys --keyserver hkp://subkeys.pgp.net 40976EAF437D05B5

comme indiqué

Si ça ne fonctionne toujours pas fait

sudo rm -r /var/lib/apt/lists
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get update

Comme indiqué

Il faudra peut être relancer les commandes pour télécharger les clefs

Merci,
pour gpg j'ai fait les commandes qui ont fonctionne.

J'avais déjà active le pare feu.
Pour l'ip et@mac avec des bon programmes (sniffer et autre) je pense que l'on peut s'introduire(pour ca il suffit de visiter le forum Backtrack) car je me connecte via wifi public.J'ai téléchargé Bastille pour augmenter la secu

Re : signatures non valides [resolu]

Si tu es un simple poste client, je ne pense pas que ce soit si simple(je connais un peu backtrack...). Si tu fait tourner un ou plusieurs serveurs, tu augmente les portes d'entrée à surveiller...
Maintenant, je ne suis pas un spécialiste en sécurité...

Si ton problème est résolu, n'oublie pas de passer ton poste en résolu

j'ai un nouveau problème avec apt-get.Les mises a jours sont reconnues mais ne peuvent pas être installées

Surement update-manager, reboot et retente, ça devrait passer.
