=head1 OPTIONS

=over 4

=item B<Global:>

=over 8

=item B<-version>

Print B<sinfp3.pl> version.

=item B<-help>

This help message.

=item B<-target> ip|ip6|hostname

Target. This is used to auto-detect some global parameters like B<device> or B<ip>.

=item B<-port> port|portList|top10|top100|top1000|all

Target port. Default for top10 ports for plugins able to handle multiple ports. This format is documented in `perldoc Net::SinFP3::Global' B<expandPorts> method.

=item B<-port-src> port

Source port to use. Not supported by all plugins.

=item B<-6>

Use IPv6 fingerprinting where available. Default to off.

=item B<-jobs> number

Maximum number of jobs in parallel. Default: 10.

=item B<-dns-resolve>

Do DNS resolution for target. Default to yes.

=item B<-dns-reverse>

Do a reverse DNS lookup for targets. Default to no.

=item B<-device> name

Network device to use. Default to auto-detect.

=item B<-thread>

Use threaded worker model (discouraged). Fork is used by default (and in Perl, it is better than ithreads).

=item B<-retry> times

Re-launch probes specified number of time. Default: 3.

=item B<-timeout> seconds

Time in seconds before timing out. Default: 3.

=item B<-pps> number

Number of packet per seconds. Default: 200.

=item B<-ip-src> ip

The source IPv4 address to use. Default to auto-detect.

=item B<-ip6-src> ip6

The source IPv6 address to use. Default to auto-detect.

=item B<-mac-src> mac

The source MAC address to use. Default to auto-detect.

=item B<-subnet-src> subnet

The source IPv4 subnet address to use. Default to auto-detect.

=item B<-subnet6-src> subnet

The source IPv6 subnet address to use. Default to auto-detect.

=item B<-ip-gateway> ip

The gateway IPv4 address to use. Default to auto-detect.
