# Taarifa Msingi

Kuna huduma ya kielekezi inayofanya kazi kwenye mwenyeji huyu. Huduma ya kielekezi ilikusudiwa kwa ajili ya majaribio na madhumuni ya kupima na inaweza kusikiliza kwenye itifaki za TCP na UDP. Mfumo hutoa nyuma data yoyote inayopokea, bila kuihariri.\
**Inawezekana kusababisha kukataliwa kwa huduma kwa kuunganisha huduma ya kielekezi kwenye huduma ya kielekezi kwenye mashine hiyo hiyo au nyingine**. Kwa sababu ya idadi kubwa sana ya pakiti zinazozalishwa, mashine zilizoathiriwa zinaweza kuondolewa kwa ufanisi kutoka kwenye huduma.\
