Como já citei antes, trabalho em uma faculdade e há a necessidade de liberar ou bloquear laboratórios conforme o professor. Para isso criei esse script que gera um menu para liberar ou bloquear conforme sua necessidade.

Note que para cada opção será necessário criar um squid.conf com as configurações necessárias.
