# Osnovne informacije
Na ovom hostu radi usluga eha. Usluga eha je namenjena testiranju i merenju i može slušati i TCP i UDP protokole. Server vraća bilo koje podatke koje primi, bez modifikacija.\
**Moguće je izazvati odbijanje usluge povezivanjem usluge eha sa uslugom eha na istom ili drugom računaru**. Zbog prekomernog broja paketa proizvedenih, pogođeni računari mogu biti efikasno isključeni iz upotrebe.\
