this page was recommended to me by stackoverflow therefore I ask my question again here.
I have performed some nmap scans, yet I have found out, that the scan over a larger area provides more results than over a small area. (Multiple testing)
online Devices: 192.168.178.30 (Android smartphone) 192.168.178.31 Windows PC.
nmap-sS 192.168.178.29-31 (scan 3 IPs) Result: 2 devices online (30,31)
nmap-sS 192.168.178.30-32 (scan 3 IPs) Result: 2 devices online (30,31)
nmap-sS 192.168.178.25-40 (scan over> 3 IPs) Result: 1 device online (31)
nmap-sS 192.168.178.28-31 (scan over> 3 IPs) Result: 1 device online (31)
The same result I get with the other scanning methods (-sT, -sU, ...)
Is there any fix for me at a scan over the entire range to get all devices?
-T2
? This will slow the scan down; you may be sending too many packets for your connection, especially if it is wireless or certain virtual NAT connections.
