Problema de conexão VPN com vpnc

Question

Eu consegui trabalhar através da VPN usando o network-manager-vpnc sem nenhum problema, mas de repente ele parou de funcionar. Este é um trecho capturado do meu syslog:

Sep  2 10:58:39 chachan-ThinkPad-L420 NetworkManager[1130]: <info> VPN service 'vpnc' disappeared

Eu tentei reiniciar, reiniciar sem fio e reiniciar a rede. Alguma idéia do que mais eu poderia testar ou fazer?

Obrigado antecipadamente!

    

Answer 1

Eu pareço ter o mesmo problema. Consegui obter uma saída de depuração útil executando:

sudo /usr/lib/NetworkManager/nm-vpnc-service --debug

de: link e depois conectando-se à vpn no gerenciador de rede. Infelizmente, isso me deixa corrigir meu problema com o vpnc-connect funcionando um pouco melhor que o network-manager-vpnc usando as instruções em O Cisco VPN não funciona sobre o 1des mas não o faz realmente funcionar, pois não sei o que fazer com a saída de depuração que fala sobre os pacotes do ESP. Talvez isso ajude você.
