Eu tenho em um Fritzbox configurado um acesso VPN. Agora estou tentando configurar um cliente VPN em uma máquina do CentOS 6. Para isso eu instalei o vpnc e o NetworkManager-vpnc e estou seguindo a descrição no link
Mas toda vez que eu tento conectar a VPN (da linha de comando "vpnc") eu recebo o erro
vpnc: vpnc.c:1166: lifetime_ike_process: Assertion '0' failed.
Além disso, se eu tentar com o networkManager com saída de depuração habilitada (nm-vpnc-service --debug) eu recebo:
** Message: <info> vpnc started with pid 13161
vpnc: vpnc.c:1166: lifetime_ike_process: Assertion '0' failed.
** (process:13150): WARNING **: <WARN> vpnc_watch_cb(): vpnc died with signal 6
Em / var / log / message (lado do cliente) eu recebo:

Alguém sabe qual é o problema aqui ou como posso obter uma mensagem de erro melhor?
