The downside is that SCTP COOKIE ECHO scans cannot differentiate between open and filtered ports, leaving you with the state open|filtered in both cases. -sI zombie host[:probeport] (idle scan) . This advanced scan method allows for a truly blind TCP port scan of the target (meaning no ...
I am able to ping to both the "foreign" IP addresses. The simplest answer is that those devices are not onyournetwork. Your network is 192.168.1.0/24 but you told nmap to scan 192.168.0.0/16 (i.e. the whole 192.168.x.x), meaning that 99% of the addresses it was told to scan w...
SYN(1 bit): Synchronize sequence numbers. Only the first packet sent from each end should have this flag set. Some other flags and fields change meaning based on this flag, and some are only valid when it is set, and others when it is clear. FIN (1 bit): Last packet from sender Wi...

Example 2 – How can Nmap help me to discover FTP servers in my subnet? File transfer protocol (FTP) is known for its weak security. The issue with file transfer protocol is that all the traffic is sent in plain text meaning that all data can be easily intercepted. An Nmap scan can ...
Nmap then labels them as unfiltered, meaning that they are reachable by the ACK packet, but whether they are open or closed is undetermined. Ports that don’t respond, or send certain ICMP error messages back (type 3, code 1, 2, 3, 9, 10, or 13), are labeled filtered. -sW (...
Nmap attempts to automatically detect your active network interface; however, there are some situations where it will fail or perhaps you will need to select a different interface in order to test networking issues. To force Nmap to scan using a different network interface, use the-eargument: ...

Here's me scanning 192.168.1.0/24 and some hosts specified again with names to check reverse DNS functionality, and filtering out only those that respond to ping, meaning they were scanned (also without the -ScanOnPingFail parameter).
