VPN no Ubuntu 9.04.

[martinelli]

Pessoal

Após um longo período de trevas voltei ao GNU/Linux. Estou usando o Ubuntu 9.04 e estou realmente impressionado com perfeição alcançada.

Contudo, como nem tudo são flores, estou enfrentando alguns problemas que creio, sejam passíveis de soluções simples.

Como trabalho numa empresa que utiliza sistemas proprietários, tenho sempre que acessar a rede usando VPN. Eu consegui configurar sem maiores problemas, mas quando tento conectar, tendo a certeza de que o usuário e senha estão corretos, a VPN informa que a conexão falhou.

Tentei várias configurações diferentes, mas... não adiantou.

Alguém sabe me dizer o que devo fazer??? A criação da VPN no WinXP não exige esforço, é só criar a VPN com o nome do servidor e informar usuário e senha. Assim, acho que no Ubuntu essa conexão também deva ser de simples configuração.

Vale ressaltar que me conecto via Wireless. E, a partir daí, faço a VPN. Mas isso funcionava normalmente com o RuinXP.

Segue abaixo o syslog com a tentativa de conexão.
