Observações: Colocar esse arquivo no diretório /etc/squid com o seguinte comando:mcopy a:\squid.conf /etc/squid/squid.conf.Logo após copiar o arquivo devemos criar dentro um diretório chamado bloqueio dentro de /etc/squid ficando /etc/squid/bloqueio.Para fazer isso segue o comando:mkdir bloqueio. No novo diretório "/etc/squid/bloqueio" serão criado dois novos arquivos: touch /etc/squid/bloqueio/palavras.txt e touch /etc/squid/bloqueio/sites.txt. Para deixar o serviço do squid automático ao iniciar o linux para digitar ntsysv e ativar o Squid.Para deixar as mensagens de erro que aparecem no Browser em Português, basta inserir essa linha no squid.conf ====>error_directory /usr/share/squid/errors/Portuguese. Disponibilizo os arquivos "sites.txt" e "palavras.txt" por e-mail!

Explicações.......
O comando citado acima mcopy é para quem copiar esse conf para o disquete com o nome de squid.conf e queira passar para o diretório /etc/squid sem montar o floppy!
mcopy a:\squid.conf /etc/squid =).

Esse conf tem alguma diferenças como o controle de acesso por Laboratórios determinados por IP e bloqueio do msn!

Neste link tem uma lista de palavras e Sites Bloqueados!!!! =)
