Dificuldade Configuração SQUID



  • Amigos, preciso de ajuda para configurar parâmetros do squid/squidguard. Não tenho experiência com ele, porém foi necessário implantação de última hora do squid devido problemas administrativos. Instalado o Pfsense 2.4.0 + squid + squidguard (não está sendo usado como firewall, apenas funcionalidade proxy). Instalado em uma VM (ambiente vmware + storage IBM v7000) com 64GB RAM, 4 CPU, 80GB de disco (instalação default). O proxy atende a quase 100 localidades diferentes espalhadas pelo Estado, ele tem um link de 1GB para atender mais ou menos 1200 usuários simultâneos conectados a internet. Monitorando, os recursos estão sendo subutilizados: CPU 40%, memo 30%, traffic graph wan (in) + wan (out) = 120Mb. Os usuários estão tendo problemas para acesso a internet: lentidão, timeout, perda de sessão, etc. Já alterei diversas vezes a configuração Local Cache e não cheguei a um consenso, fiz uma alteração também após consulta em foruns na linha "url_rewrite_children 256", alterando o valor default de 16 para 256, isso deu uma melhorada. Alguém teria uma sugestão de configuração? Fiz esta configuração abaixo hoje que vou testar na próxima segunda dia 6/11/17 retornada com o comando squid -k parse. Obrigado desde já.

  • Amigos, preciso de ajuda para configurar parâmetros do squid/squidguard. Não tenho experiência com ele, porém foi necessário implantação de última hora do squid devido problemas administrativos. Instalado o Pfsense 2.4.0 + squid + squidguard (não está sendo usado como firewall, apenas funcionalidade proxy). Instalado em uma VM (ambiente vmware + storage IBM v7000) com 64GB RAM, 4 CPU, 80GB de disco (instalação default). O proxy atende a quase 100 localidades diferentes espalhadas pelo Estado, ele tem um link de 1GB para atender mais ou menos 1200 usuários simultâneos conectados a internet. Monitorando, os recursos estão sendo subutilizados: CPU 40%, memo 30%, traffic graph wan (in) + wan (out) = 120Mb. Os usuários estão tendo problemas para acesso a internet: lentidão, timeout, perda de sessão, etc. Já alterei diversas vezes a configuração Local Cache e não cheguei a um consenso, fiz uma alteração também após consulta em foruns na linha "url_rewrite_children 256", alterando o valor default de 16 para 256, isso deu uma melhorada. Alguém teria uma sugestão de configuração? Fiz esta configuração abaixo hoje que vou testar na próxima segunda dia 6/11/17 retornada com o comando squid -k parse. Obrigado desde já.
