    Searching for Network Devices by IP address and Manufacture

    Hi, I'm wondering if there is any suggestions for searching for what devices are connected on a network. I know there is the arp command but it only shows current traffic to the computer where the command was sent. In windows I have used programs like Belarc Advisor or Advanced IP Scanner. I'm wondering what commands or applications Linux has and what IT administrators like to use. Thanks

    Angry IP Scanner sorta kinda looks and acts like Advanced IP Scanner.

    You will need to download and install the *.deb file: https://angryip.org/

    We installed Nagios at a client site. Worked fine for what we needed. Here are other options:

    However, if you just want something fast and quick, nmap is the product for you.

    You can do a ping scan ("-sP") that also collects other information about the connected devices. The "-n" switch tells nmap not to try and resolve IP addresses to hostnames.

    Code:
    $ sudo nmap -sP -n 192.168.100.0/24
    Starting Nmap 7.93 ( https://nmap.org ) at 2023-11-25 14:37 EST
    Nmap scan report for 192.168.100.1
    Host is up (0.0067s latency).
    MAC Address: 50:EB:F6:11:2D:00 (Asustek Computer)
    Nmap scan report for 192.168.100.5
    Host is up (0.0073s latency).
    MAC Address: 30:05:5C:43:BC:B3 (Brother industries)
    Nmap scan report for 192.168.100.27
    Host is up (0.088s latency).
    MAC Address: D0:73:D5:36:96:4C (Lifi Labs Management)
    Nmap scan report for 192.168.100.36
    Host is up (0.017s latency).
    [etc.]
    Trinity uses nmap in The Matrix so you know it must be good!
