# Osnovne informacije
|
|
|
|
Na ovom hostu radi echo servis. Echo servis je namenjen za testiranje i merenje i može slušati na TCP i UDP protokolima. Server vraća sve podatke koje primi, bez modifikacije.\
|
|
**Moguće je izazvati uskraćivanje usluge povezivanjem echo servisa sa echo servisom na istom ili drugom računaru**. Zbog prekomerno velikog broja paketa koji se proizvode, pogođeni računari mogu biti efikasno isključeni iz usluge.\
