ClearOS na Amazon

Imagens do ClearOS já se encontram disponíveis (ainda em beta) em http://www.clearcenter.com/support/documentation/clearos_install_guide/amazon_ec2

Quando instalei, a primeira coisa que fiz foi criar um usuário administrativo para substituir a conta root e para minha surpresa não era possível logar com o usuário recém criado! Após alguma pesquisa encontrei no fórum a resposta http://www.clearfoundation.com/component/option,com_kunena/Itemid,232/catid,38/func,view/id,45744/

Basicamente adicionei as entradas abaixo em /var/clearos/base/access_control/custom/access_control no formato:

Uma vez iniciado o ClearOS é possível fechar uma VPN com minha Amazon VPC, por enquanto estou configurando as rotas manualmente mas vou testar essa configuração de forma automática via DHCP.
