Version: 1.5.1.1

Status: Done



 

Usage

nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-m retransmits] (-f filename)|(<scan_range>) 

Options:
        -v              verbose output. Print all names received
                        from each host
        -d              dump packets. Print whole packet contents.
        -e              Format output in /etc/hosts format.
        -l              Format output in lmhosts format.
                        Cannot be used with -v, -s or -h options.
        -t timeout      wait timeout milliseconds for response.
                        Default 1000.
        -b builddir     Create a directory for each server name in the
                        folder builddir.
        -r              use local port 137 for scans. Win95 boxes
                        respond to this only.
                        You need to be root to use this option on Unix.
        -q              Suppress banners and error messages.
        -s separator    Script-friendly output. Don't print
                        column and record headers, separate fields
                        with separator.
        -h              Print human-readable names for services.
                        Can only be used with -v option.
        -m retransmits  Number of retransmits. Default 0.
        -f filename     Take IP addresses to scan from file filename.
                        -f - makes nbtscan take IP addresses from stdin.
        <scan_range>    what to scan. Can either be single IP
                        like 192.168.1.1 or
                        range of addresses in one of two forms: 
                        xxx.xxx.xxx.xxx/xx or xxx.xxx.xxx.xxx-xxx.

Examples

        nbtscan -r 192.168.1.0/24
                Scans the whole C-class network.
        nbtscan 192.168.1.25-137
                Scans a range from 192.168.1.25 to 192.168.1.137
        nbtscan -v -s : 192.168.1.0/24
                Scans C-class network. Prints results in script-friendly
                format using colon as field separator.
                Produces output like that:
                192.168.0.1:NT_SERVER:00U
                192.168.0.1:MY_DOMAIN:00G
