[Internet] Connexion impossible sur certains sites ; pb DHCPCD 9.0.0-2 [Résolu]

[jako]

Bonjour,
Depuis ma dernière maj je ne peux plus me connecter sur certains sites.
J'ai vu sur le forum anglais que cela serait du à la nouvelle version de DHCPCD 9.0.0-2 qui ne permettrait pas la connexion en IPv4 avec Network Manager.
Il faudrait remettre DHCPCD 8.1.7-1.

https://bbs.archlinux.org/viewtopic.php?id=254857

Je pense être dans la même situation puisque j'ai vérifié que j'ai DHCPCD 9.0.0-2. Mais j'ai un peu de mal à suivre la procédure pour faire un Downgrade .
De plus je fais toujours "pacman -Syu" et donc je ne sais pas comment retrouver la version antérieure.
Merci de votre aide.

Les sites redeviennent accessibles ??

[laurent85]

Bonjour,
dhcpcd n'est pas une dépendance de NetworkManager. NM fonctionne aussi bien sans dhcpcd. Est-ce que le ping des sites en question répond ?

[jako]

Bonjour,
Voici la réponse au ping du système à la mise en route sur 5 sites.

[jjr@archtest ~]$ ping paypal.com
ping: connect: Le réseau n'est pas accessible
[jjr@archtest ~]$ ping master-outillage.com

ping: connect: Le réseau n'est pas accessible
[jjr@archtest ~]$ ping meteofrance.com
ping: connect: Le réseau n'est pas accessible
[jjr@archtest ~]$

Je fais la commande : "sudo dhcpcd"
et voici le résultat des ping après :

Questions : puis je supprimer dhcpcd ? Comment revenir à la version antérieure de dhcpcd ? Quid des maj après?
Merci

[benjarobin]

Peux tu donner la sortie de :

Code : Tout sélectionner

pacman -Q dhcpcd networkmanager linux
uname -a
grep -r . /etc/NetworkManager/conf.d/

Ainsi que la sortie (en ayant le problème) de :

Code : Tout sélectionner

ip a
route -n
cat /etc/resolv.conf

Puis après avoir lancé dhcpcd, les mêmes commandes (sauf pacman...)

[jako]

Voila les sorties des commandes :
1 . au lancement de Arch :

Code : Tout sélectionner

[jjr@archtest ~]$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver fd0f:ee:b0::1
[jjr@archtest ~]$ 

2 . Après avoir lancé dhcpcd

Code : Tout sélectionner

jjr@archtest ~]$ cat /etc/resolv.conf
# Generated by resolvconf
nameserver 192.168.3.254
nameserver fd0f:ee:b0::1
[jjr@archtest ~]$ 

[benjarobin]

Je vais faire une dépression... Je demande la sortie de 6 commandes, et j'ai la sortie que d'une seule ! C'est un concours ? Pourquoi personne ne veux jamais répondre à toutes les questions ?!
Désolé mais comme tu n'es pas le seul à le faire, cela devient agaçant...

C'est comme si tu avais ce bug, https://bugs.archlinux.org/task/66231, mais normalement dhcpcd ne devrait pas être appelé.
Après un redémarrage, peux tu donner la sortie (redirige la sortie vers un fichier et ensuite tu nous donnes le fichier) de :

Code : Tout sélectionner

sudo journalctl -b | grep -iE "network|dhcp"
sudo grep -r . /etc/NetworkManager/ /usr/lib/NetworkManager/ /run/NetworkManager/ /var/lib/NetworkManager/ | grep -i dhc
find /etc/systemd/system
systemctl list-unit-files --state=enabled
systemctl list-units --state=running
ps -AF | grep "[d]hcp"

[jako]

Pour le bug , oui j'avais vu cela c'est pour cela que je demandai si je pouvais désinstaller dhcpcd ou revenir à une version antérieure

Voila le résultat des commandes après redémarrage du système. J'espère que c'est conforme à ta demande.

Supprime cette ligne dans /etc/NetworkManager/NetworkManager.conf, NM utilisera son dhcp interne :

Code : Tout sélectionner

dhcp=dhcpcd

Tu peux aussi désinstaller dhcpcd

C'est bien cette ligne que je cherchais initialement (dhcp=dhcpcd).

Sais tu pourquoi tu l'as ajouté ?

Je te conseille de garder dhcpcd cela dépanne toujours

Bonjour à vous,
Je ne sais plus pourquoi j'ai mis cette ligne lors de l'installation en 2018. J 'ai du lire cela quelque part car je n'ai pas la connaissance pour faire cela.
Je viens de la supprimer et le problème est règlé .
Merci à tous les deux pour votre aide efficace.

Bonjour,
Même problème, merci pour la solution, ça ne bloquait que ma boite mail et c'était évidemment très embêtant.

Même cause que ce que cite jako, l'ajout de cette ligne a été préconisée comme un remède (qui a fonctionné jusqu'ici) à la suite d'un dysfonctionnement de connexion sur certains sites.
Sans doute effectivement en 2018.

Salut à tous.
