nmap remote os detection

Hi,

I would like to know if I can use nmap to detect remote OS exclusively
without doing the port scanning. There doesn't seem to be a switch to turn
off the default TCP SYN scan.

Thanks

Keith

No. The OS fingerprinting analyzes data gathered during the scan.

you can try passive os fingerprinting if possible. try ettercap and p0f !
