hi, from /usr/src/sys/i386/conf/LINT # # TCP_DROP_SYNFIN adds support for ignoring TCP packets with SYN+FIN. This # prevents nmap et al. from identifying the TCP/IP stack, but breaks support # for RFC1644 extensions and is not recommended for web servers. # options TCP_DROP_SYNFIN #drop TCP packets with SYN+FIN I hope it is what you need. cya Alvaro On Thu, 28 Mar 2002, Moti Levy wrote: > I want to stop nmap from detecting my os . > > > > > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-security" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
