Zvadaro, muchengeti anoita chimwe chekubatanidza nevhavha pamusoro pechipangara 20 kuitira kuti mafaira chaiwo awedzere kuitika.
Nzvimbo yakashata yekutumira mirairo uye mafaira pamusoro peFTP inogona kuchinjwa, asi muyero uripo kuitira kuti vateresi / mapurogiramu ezvirongwa, ma routers, uye firewalls vose vanobvumirana pamatokari mamwe kuti kugadzirisa zvive nyore nyore.
