The specifier 0-255.0-255.13.37 will perform an Internet-wide scan forĪll IP addresses ending in 13.37. Ranges need not be limited to the final octets: My printer/scanner Samsung M2070 is connected through Wi-Fi, and my Ubuntu is 18.04 (Bionic) I have found a tutorial in french: //tutoriel/installerimprimantesamsung The main point is to edit 2 files, so as to add the following: /etc/sane.d/nf Samsung M2070 Series usb 0x04e8 0x3469 tcp 192.168.1.35 (the ip address.

List of numbers or ranges for each octet. Than specify a normal IP address, you can specify a comma-separated Nmap supports this through octet range addressing. First, we will see the command line tools natively available on Ubuntu 20.04 for scanning a network then, we will see a gui program build for this purpose. 255 because they may be used as subnet network and broadcastĪddresses. arp-scan is a command-line tool that uses the ARP protocol to discover and fingerprint IP hosts on the local network.
