Ako ne znate šta se nalazi iza usluge, pokušajte da napravite HTTP GET zahtev.

**UDP skeniranja**\
nc -nv -u -z -w 1 \<IP> 160-16

Prazan UDP paket se šalje na određeni port. Ako je UDP port otvoren, nema odgovora sa ciljne mašine. Ako je UDP port zatvoren, ICMP paket o nedostupnom portu treba da se vrati sa ciljne mašine.\

UDP skeniranje portova je često nepouzdano, jer vatrozidi i ruteri mogu odbaciti ICMP\
pakete. To može dovesti do lažnih pozitivnih rezultata u vašem skeniranju, i redovno ćete videti\
UDP skeniranja portova koja pokazuju sve UDP portove otvorene na skeniranoj mašini.\
Većina skeneri portova ne skeniraju sve dostupne portove, i obično imaju unapred postavljenu listu\
“zanimljivih portova” koji se skeniraju.
