Packages and Binaries:
NBTscan is a program for scanning IP networks for NetBIOS name information. It sends NetBIOS status query to each address in supplied range and lists received information in human readable form. For each responded host it lists IP address, NetBIOS computer name, logged-in user name and MAC address (such as Ethernet).
This program is useful for security checks, network discovery and forensics investigations.
How to install:
sudo apt install nbtscan
Scan networks for NetBIOS name information
[email protected]:~# nbtscan --help NBTscan version 1.7.2. This is a free software and it comes with absolutely no warranty. You can use, distribute and modify it under terms of GNU GPL 2+. Usage: nbtscan [-v] [-d] [-e] [-l] [-t timeout] [-b bandwidth] [-r] [-q] [-s separator] [-m retransmits] (-f filename)|(<scan_range>) -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 bandwidth Output throttling. Slow down output so that it uses no more that bandwidth bps. Useful on slow links, so that ougoing queries don't get dropped. -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 192.168.0.1:ADMINISTRATOR:03U 192.168.0.2:OTHER_BOX:00U ... nbtscan -f iplist Scans IP addresses specified in file iplist.
