  1. Galera!

    Muita boa tarde, estou com um problema que ainda não sei como resolver.

    Minha conexão virtua cai toda hora, e depois de algumas hora verificando os log, percebi que após algumas tentativas de acesso não autorizados o linnk cai, e tenho que reiniciar o micro.

    segue abaixo parte do syslog
