Hi, I understand that certain parameters within TCP protocol definition are set to different default values by different operating systems and this inturn is used for TCP/IP fingerprinting. But, Is there a TCP/IP fingerprint database that tells the relation between the various TCP protocol fields and the corresponding values that might determine the type of Operating System ?



Which is the best fingerprinting tool and how far is fingerprinting helpful in safeguarding against attacks ?



I searched the internet, i got only fingerprint submission pages, but did not get a database. Any ideas ?



Thx in advans, Karthik Balaguru


nmap with the -O switch does very well, and is likely the most used with the biggest fingerprint database.

But if there aren't many services responding, take the results with a grain of salt.

Thx for the inputs.

Okay !

I came across IceScan, an open source tool (GPL licenced) and a list of tools in the below link also -

But, i think just as you told, nmap seems to be excellent !!
