Conexão cliente do OpenVPN

[lvrodrigues]

Saudações:

Instalei o OpenVPN, versão 2.0.9 no Ubuntu 9.04+ e estou tendo problemas em estabelecer uma conexão com o servidor. Sei que o problema é local, pois consigo conectar o servidor pela VPN com uma máquina Windows. Quando tento estabelecer a conexão, recebo o seguinte log:

Pesquisei na internet e eles relatam um erro com o módulo TUN, mas está instalado e funcionando normalmente. Uso interfaces TAP para máquinas virtuais. Listando o diretório de dispositivos...

luciano@luciano:~/Documentos/openvpn$ ls /dev/net/tun -al

Alguém pode ajudar-me a resolver o problema?


Grato,

Luciano.
