Hello List, i would like to test if i can reach an open TCP and UDP Port. Here is the way i use to test a tcp port (-sT does a full handshake, right?!): /usr/bin/nmap -sT --data-length 10 -n -q -r -e eth0:0 -P0 --open -T Aggressive -p 1234 123.123.123.123 The results seem to make sense here. This is the way how i check a UDP Port: /usr/bin/nmap -sU --data-length 10 -n -q -r -e eth0:0 -P0 --open -T Aggressive -p 1234 123.123.123.123 the weird thing is that it still reports an open port if i unplug the network cable of 123.123.123. Where can i read up how nmap does its udp scan?
