Sur Ubuntu 16.04, j'ai déjà suivi quelques tutoriels pour reconstruire le gestionnaire de réseau, également installé via apt-get install network-manager-l2tp network-manager-l2tp-gnome
.
Cela fonctionnait jusqu'à hier, quand un message au hasard disait The VPN connection failed because the VPN service failed to start
. Il n'y a aucune erreur de configuration car les mêmes informations d'identification VPN et le même hôte sont utilisés dans un autre Ubuntu, également 16.04 et Windows 8.1.
En regardant /var/log/syslog
:

J'ai déjà essayé de supprimer network-manager-l2tp
et de -gnome
réinstaller les packages, mais j'ai toujours la même erreur.
Une solution?
sudo ike-scan <address>
et qu'il renvoie quelque chose sur la liaison et le port déjà utilisés, il est possible que celasystemctl stop strongswan
ne soit pas suffisant etcharon
qu'il fonctionne toujours. On peut confirmer que l'exécutionsudo netstat -npl
et la vérification du bloc supérieur où il est montré les processus et les ports utilisés. Je pouvais complètement arrêter Charon de courirsudo service strongswan stop
, je ne sais pas pourquoi le comportement était différentsystemctl
.
