W systemie Ubuntu 16.04 wykonałem już kilka samouczków, aby odbudować menedżera sieci, również zainstalowanego za pośrednictwem apt-get install network-manager-l2tp network-manager-l2tp-gnome
.
Działało do wczoraj, kiedy pojawiła się przypadkowa wiadomość The VPN connection failed because the VPN service failed to start
. Nie ma błędów w konfiguracji, ponieważ te same poświadczenia VPN i host są używane w innym Ubuntu, również 16.04 i Windows 8.1.
Patrząc na /var/log/syslog

Ja już próbowałem usuwania network-manager-l2tp
i -gnome
pakiety i zainstalować je ponownie, ale nadal mam ten sam błąd.
Jakaś poprawka?

sudo ike-scan <address>
i zwróci coś o powiązaniu i porcie już używanym, możliwe, żesystemctl stop strongswan
to za mało icharon
nadal działa. Można potwierdzić, że uruchomionosudo netstat -npl
i sprawdzono górny blok, w którym pokazano procesy i używane porty. Mógłbym całkowicie zatrzymać bieganie charonasudo service strongswan stop
, nie jestem pewien, dlaczego tak sięsystemctl
zachowało.-s
Przełącznikike-scan
ok zaoszczędzić trochę polowanie PID). Może cię nawet uratowaćsudo
:ike-scan -s 60066 <IP>
ike-scan
i powiedział, że port 500 był już w użyciu. za pomocąnetstat -npl
pokazano, żedocker-proxy
go używał. Ponieważ nie jestem zależny od dokera, zatrzymałem gosudo service docker stop
i mogłem pomyślnie połączyć się z L2TP VPN.Ta odpowiedź dotyczy połączenia z kontem Cisco Meraki w sieci VPN L2TP / IP. Rozwiązanie działa na moim systemie Ubuntu 16.04. Wszystkie instrukcje są kopiowane bezpośrednio z odpowiedzi Pigmana w tym wątku na forum Meraki . Czapki z głów przed nim, oszczędził mi godzin frustracji.
sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp
i `sudo apt-get update sudo apt-get install network-manager-l2tpsudo apt-get install network-manager-l2tp-gnome
sudo service xl2tpd stop
sudo systemctl disable xl2tpd
Jeszcze kilka kroków od poprzednich odpowiedzi, żeby być niezawodnym
sudo service strongswan stop
sudo systemctl disable strongswan
