Ce se mai întîmplă cînd pornesc mașina linux fără firewall și cu o grămadă de servere de test rulînd?Mai nimic,decît niște oameni ( de fapt niște programe automate ) care vor neapărat să intre pe contul de administrator sau să trimită mailuri de pe calculatorul meu sau cine știe ce lucruri dubioase ! :) :)  Poți să fi sigur că și pe calculatorul tău se întîmplă cam la fel-chiar dacă ai windows!
