Instalei o CentOS 6.3, o OpenSUSE 12.1 e o Ubuntu 12.04 no VMware Workstation 9. Em todos esses casos, quando uso ping
para verificar a conectividade de rede, recebo uma resposta adequada, mas ao tentar atualizá-los usando yum
, yast
e apt-get
, todos eles retornam mensagens de erro como "não é possível acessar o repositório".
Alterei as configurações de rede nos sistemas operacionais e também no VMware várias vezes, mas nada aconteceu.
Também do CentOS (e provavelmente de outros sistemas operacionais) não posso usar o firefox para acessar a Internet e não posso usar wget para buscar uma página como yahoo.com, ele diz: "Conectando a yahoo.com (yahoo.com) | 98.138. 253.109 |: 80 ... falhou: Conexão recusada.
"
no Ubuntu eu vejo / vejo isso:
