  1. amigo tem como se postar seu script do squid3.. eu tenho aki mas achei i 2x melhor.
    como vc ta fazendo o proxy..
    nat, parent...

  2. pro amigo acima, pra remover geral, apt-get --purge remove squid*



  3. agora minha duvida,,

    server mk+hotspot = gw
    linux ubuntu server 8.04-squid 2.6 - bind9. + hd 80 sata + 3gb ram ddr2 ,eth0 3com..

    galera, tenho rodando aqui um proxy em paralelo com mk 'cliente do mk '

    com o seguinte redirecionamento e mais nada...

    add chain=dstnat src-address=!192.168.2.8 dst-address=!192.168.2.8 protocol=tcp dst-port=80 src-address-list=clientes action=dst-nat to-addresses=192.168.2.8 \
    to-ports=3128 comment="" disabled=no

    192.168.2.8 eh o proxy
    address-list clientes, é pq uso mask /30 um range pra cada cliente..

    varios dias fuçando na net sobre squid, pedacin de um pedacin de outro,,, cheguei a esse squid.conf

  4. pois eh isso,,

    em 2 dias, os 3gb de ram, vai embora apenas sobrando 15mb,,, mais nao para,, deve ser alguma reserva pro sistema nao entrar em swap,,, nao sei,,

    encima dessa confg, estou rodando 50 clientes

    lenbrando, esse squid.conf nao foi eu q fiz, e sim catando pedacinho de um pedacinho de outro,,
