Instalação dos certificados no navegadores
Após configurar o squid3 e gerar os certificados, está na hora de instalar nos navegadores. Essa etapa é uma continuação do item "10) Disponibilizar o certificado para os navegadores" da página anterior.
1) Firefox
Você deve acessar no navegador:
http://SEU-IP/certificado
Clique no certificado mostrado na etapa 1. Após clicar, aparecerá a etapa 2 "Recebendo o certificado". Clique em todas as caixas e depois no botão "OK" da etapa3.
2) Google Chrome
Diferentemente do Firefox, o Chrome é mais complicado. Você precisa baixar o certificado e adicionar ao navegador sempre na aba "Autoridade".
Abaixo vejamos as etapas:
Clique no certificado para realizar o download:
Clique em "Personalizar e Controlar o Google Chrome" etapa 1 e depois em "Configurações" da etapa 2.
Clique agora em "Mostrar Configurações Avançadas".
Em HTTPS/SSL clique no botão "Gerenciar Certificados"
Sempre instale o certificado sempre em "Autoridades" na etapa 1 e depois na etapa 2 no botão "Importar".
Escolha o certificado onde você realizou o download e clique em "Open".
Marque todas as caixas e depois clique em "OK".
Seu certificado deve constar na lista depois dessa etapa. Agora basta clicar no botão "Concluído"

Muito bom artigo! Favoritado. Vou usar como guia essa semana.
Opa, muito bacana! E veio em uma hora muito oportuna pra mim! Obrigado!! Só uma questão didática: essa troca de certificado, é feita com qual objetivo? Enfim, vi que dá o erro de certificado nos navegadores, só não entendi pq isso acontece e a necessidade de "enganá-los" com um certificado intermediário. Isso não pode gerar uma possível brecha na segurança? Um abraço, e novamente, obrigado!

Olá Leonardo,
Como o tráfego https é criptografado, precisamos interceptá-lo para conseguir abrir o conteúdo e tomar as ações de bloqueios e liberações.
Assim precisamos regenerar os certificados para os usuários.
Leia essa referência do artigo
http://wiki.squid-cache.org/Features/DynamicSslCert e sobre o tema.

Leonardo,
Quanto a questão da segurança, o funcionamento é semelhante ao ataque man-in-the-middle onde você acha que está acessando o site diretamente, mas na verdade há uma outra pessoa no caminha vendo tudo que se passa.
O arquivo /etc/squid3/certificado/empresa.pem não deve ser exposto para não comprometer a segurança.
Apenas o arquivo /etc/squid3/certificado/empresa.der deve ser divulgado.
Caso divulgue por engano o arquivo, pode gerar novos certificados para o servidor e desktop.
Um outro detalhe é que o uso do proxy geralmente é interno. Então não está exposto diretamente na internet.
Nunca encontrei nada sobre um exploração nesse sentido.
Um outro fator importante é que todos os pacotes utilizados pertencem a sessão main do Debian, onde há um rígido controle e verificação de segurança.
Na minha visão o que potencializaria essa situação é a exposição do arquivo citado acima.
Até!

Bom dia, me desculpe pela pergunta pois ainda sou um pouco inexperiente quando o assunto é linux mas, quando se usa proxy transparente essa solução funciona ?

Muito bom o artigo parabéns, o unico problema que vejo é que a maioria dos artigos não utiliza autenticação de usuários e acho que não é o que acontece na maioria dos lugares onde será utilizado, é sempre legal tratar artigos relacionados a segurança/servidores com algum tipo de autenticação e controle de usuários.
PS. este artigo poderia se tornar um e-book bem legal se complementar com a configuração do squidguard, criação de grupos de bloqueio e usuários e talvez o sarg.

Felipe,
Essa solução é baseada em proxy transparente como pode observar depois nas configurações do squid.conf:
http_port 3128 transparent
https_port 3129 transparent ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/etc/squid3/certificado/empresa.pem

Willian,
Legal a sugestão, caso tenha interesse em compilar um ebook, podemos conversar melhor.
Esse artigo é baseado em proxy transparente.
A compilação que é realizada aqui já suporta autenticações como pode ver no arquivo /var/cache/apt-build/build/squid3-3.4.8/debian/rules :
--enable-auth-basic="DB,fake,getpwnam,LDAP,MSNT,MSNT-multi-domain,NCSA,NIS,PAM,POP3,RADIUS,SASL,SMB"
Voce pode remover o transparent em http_port e https_port e adicionar o método que você preferir.
Até!

Muito legal o artigo irmão, uma vez fiz isso no Pfsense, gerando o certificado e tudo mais e funcionou tranquilo, embora eu não seja fã de proxy transparente. Geralmente quando uso o squid, prefiro o proxy nos navegadores, assim tenho um controle muito melhor sobre o acesso, mas é apenas uma questão de gosto. Mas o artigo está show...

Obrigado WBaluz !
Sérgio Abrantes, fiz exatamente os passo como no tutorial. Os erros aconteceram na compilação, executando o "apt-get build-dep squid3".
WBaluz, também prefiro o proxy no navegador. Faço a distribuição via WPAD e acho mais interessante o controle... Vou testar esse tutorial sendo não transparente =)
Um abraço, pessoal!

Bom dia leorocco,
A etapa citada "apt-get build-dep squid3" não é a compilação, mas sim baixar as dependências do pacote do squid3.
Segue o comando do meu desktop:
root@abrantes:/etc/network# apt-get build-dep squid3
Lendo listas de pacotes... Pronto
Construindo árvore de dependências
Lendo informação de estado... Pronto
Note, selecting 'libcap-dev' instead of 'libcap2-dev'
Os NOVOS pacotes a seguir serão instalados:
cdbs comerr-dev krb5-multidev libcap-dev libcppunit-1.13-0 libcppunit-dev libdb-dev libdb5.3-dev libecap2 libecap2-dev
libexpat1-dev libgmp-dev libgmpxx4ldbl libgssrpc4 libkadm5clnt-mit9 libkadm5srv-mit9 libkdb5-7 libkrb5-dev libldap2-dev libltdl-dev
libnetfilter-conntrack-dev libnfnetlink-dev libpam0g-dev libsasl2-dev libxml2-dev nettle-dev pkg-config
0 pacotes atualizados, 27 pacotes novos instalados, 0 a serem removidos e 2 não atualizados.
É preciso baixar 5.058 kB de arquivos.
Depois desta operação, 18,3 MB adicionais de espaço em disco serão usados.

Leorocco, tb acho mais interessante fazer assim, pois você tem mais controle sobre tudo que passa por ele, além de matar tanto http quanto https. O WPAD funciona muito bem, principalmente para quem gosta de trabalhar (não só) com o PFsense+proxy transparente, habilitando a tag "intecept" para ele ler as págs https.. Eu gosto de configurar o iptables para fazer o redirecionamento automático, para a porta do squid, caso um experto tente tirar o proxy do navegador kkkkkk.

WBaluz,
Mas esse artigo aborda tanto http como https (esse em especial que não vem habilitado por padrão no pacote pré-compilado). Faço o redirecionamento pelo iptables das portas para o squid tratar.
Assim não há como navegar sem passar pelo proxy. E se quiser também, pode adicionar o proxy manualmente no navegador.
Até!

Pelo,
Exato, isso mesmo q falei, pois caso o squid não seja compilado da maneira do artigo, o redirecionamento só funciona para a porta 80, caso faça pela 443, ele vai apresentar erro de certificado.. No caso do WPAD, ele deixa o Servidor DNS passar as confs automáticas em relação ao proxy, Assim seria uma solução para quem quer usar o proxy transparente + tratamento de paginas https.

Bom dia pessoal, gostaria de parabenizar ao Sergio pelo tutorial que foi o primeiro que vi funcionar , antes so conseguia filtrar https usando o pfsense. Gostaria de saber se alguém resolveu um problema que aconteceu comigo, por ex o aplicativo do banco itau e do Bradesco não funcionam por conta do certificado importado pro navegador, tentei colocar eles tanto ip como dominio numa whitelist do squid e também com o iptables para não passar pelo proxy, porem não deu certo. Alguém passou por isso e resolveu? Obrigado

Boa tarde, excelente artigo, fiz todo o procedimento, funcionou blz, porém, estou com problema na atualização do Windows, no meu caso o 10, quando mando atualizar, me aparece o erro: (0x800946004), se eu tiro a linha de captura da porta 443, funciona normalmente, teria alguma solução pratica no próprio proxy sem ter que mexer nas estações?

Clayton,
Que bom que deu certo.
Erros de certificado o Squid bloqueia com uma tela parecida com a tela de bloqueio de site. Podemos transferir para o usuário a responsabilidade de, por exemplo, adicionar como execeção de segurança.
Para isso, adicione a seguinte linha: "sslproxy_cert_error allow all".
Uma outra alternativa é fazer com que o Squid não faça a regeneração dos certificados para sites ou IPs.
Adicione duas ACLs.
acl ssl-ignore-hosts dstdomain "/etc/squid3/ssl-ignore-hosts"
acl ssl-ignore-ips dst "/etc/squid3/ssl-ignore-ips"
Depois coloque-as antes de "ssl_bump server-first all" como abaixo:
ssl_bump none ssl-ignore-hosts
ssl_bump none ssl-ignore-ips
ssl_bump server-first all
Dentro de "/etc/squid3/ssl-ignore-hosts" coloque microsoft.com por exemplo.
Esses passos devem resolver.
Até!

Boa tarde Sérgio, ótimo artigo, implementei sem problemas. O incrível é que estou com um problema básico, mas está me tirando o sono. Nesta versão nova do Debian (na versão anterior, não tinha o problema), como efetuar o reload (por exemplo squid3 -k reconfigure, service squid3 reload) o comando não funciona, tenho que dar um kill -9 processo do squid, para parar e depois reiniciar o squid. Aguardo, muito obrigado, grande abraço!

Enviei uma mensagem pra você pelo VOL com o meu squip em /etc/init.d/squid3.
Ele está padrão da instalação e está funcionando.
Até!

Excelente artigo e obrigado por compartilhar. Nos computadores e notebooks funcionou muito bem, porém em celulares não consegui acessar sites https, ou até mesmo aplicativos bancários. Vi que nos celulares Android existe uma opção de instalar certificados, porém não lê certificados .der. Sabe qual pode ser a solução? Obrigado

Excelente artigo muito bom mesmo. Mas estou com problemas na hora de rodar o comando:
/usr/lib/squid3/ssl_crtd -c -s /etc/squid3/certificado/ssl_db -M 4MB
ele responde:
bash: /usr/lib/squid3/ssl_crtd: Arquivo ou diretório não encontrado
Alguém pode me ajudar por favor.

Que legal chaplinux!
Me mande via VOL uma mensagem com o teu firewall.
Alguma regra deve estar invalidando a regra pra fazer transparente.

Sérgio, muito bom o artigo, só acredito que nessa versão do Squid, deve ser substítuido o transparent por intercept no squid.conf

Tudo certo itsl3v1s?

Como ficaria a configuração e o que muraria?

Parabéns pelo artigo Sergio Abrantes.
Segui todos os passos do artigo, funcionou quase que perfeitamente, só estou com um problema com o outlook, acessando pelo navegador, tem hora que abre, tem hora que não, fica uma página em branco após fazer o login, e não consegui descobrir onde está o erro, não sei se está no squid.conf ou se está no firewall, quando coloco para passar direto sem ser pelo squid funciona normal.
Gostaria de ter ajuda para conseguir resolver esse problema pois já bati demais a cabeça e não consegui.
Segue o firewall e o squid.conf:

Mensagem
Parabéns pelo artigo Sergio Abrantes.
Segui todos os passos do artigo, funcionou quase que perfeitamente, só estou com um problema com o outlook, acessando pelo navegador, tem hora que abre, tem hora que não, fica uma página em branco após fazer o login, e não consegui descobrir onde está o erro, não sei se está no squid.conf ou se está no firewall, quando coloco para passar direto sem ser pelo squid funciona normal.
Gostaria de ter ajuda para conseguir resolver esse problema pois já bati demais a cabeça e não consegui.
Segue o firewall e o squid.conf:

Parabéns pelo artigo, Sérgio e muito obrigado por compartilhá-lo !! ;)
Em breve o colocarei em prática. Atualmente tenho um cenário similar com o debian 7 squid3 (http) e auxilio do dansguardian ,e, como o servidor está em produção, criarei um nova máquina como Jessie.
Obrigado !!!

Pessoal,
Google Chrome não aceita mais certificados do tipo sha1 como o utilizado nesse artigo. Mozilla em breve também não aceitará.
Fiz uma dica explicando o que precisa mudar pra funcionar.
O link é:

Boa tarde
Meu Firewall e em servidor separado do squid3, ent coloquei a regra no meu firewall,
iptables -t nat -A PREROUTING -i ### -p tcp --dport 80 -j DNAT --to-destination ###.###.###.###:3128
liberei o Mascaramento no servidor squid, mas toda a regra do squid de acesso liberado fala que não tem permissão e os sites bloqueados fala que esta sem conexão com a internet.
