Vurraz Posted December 23, 2015 Share Posted December 23, 2015 Hello, I've got one simple question - Is Nmap using up less bandwith from my connection if I set Nmap to work on -T1 speed? Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Vurraz Posted December 23, 2015 Author Share Posted December 23, 2015 Oh, and another question came to mind - Am I going to be less stealthy if I use multiple T1 scans at the same moment? (Like a -T1 sS scan in one terminal, and a -T1 -sU scan on another terminal within the same computer) Quote Link to comment Share on other sites More sharing options...
winter_soldier Posted January 3, 2016 Share Posted January 3, 2016 Depends on what your scanning. T1 is a far less aggressive scan when compared to T5, you might want to look into other speed options sS can be mistaken for syn-flood attacks on some basic firewalls and IDS systems, sometimes sT is quicker across network boundaries sU UDP can be very unreliable, combine it with Application triggers -A (aggressive scan) to more accurately determine open ports, but then increases the chances of detection Also nmap inserts a fixed string into all packets any IDS (example Snort) can easily fingerprint an nmap scan, think of alternative scanning engines When in doubt or unsure man nmap Quote Link to comment Share on other sites More sharing options...
