I just wanted to ask what if we just ping the broadcast ip instead of pinging all the individual ips, will that miss out any particular device or was the purpose here to show how a script works and how to ping using a bash script? Your scripts are really amazing and I’m enjoying them but I just had this doubt cause we can you know ping only the broadcast ip instead of running a for loop. Clearly I’m missing something, what is it?
The broadcast IP doesn't have any devices connected to it. The DNS server on a network assigns IPs to devices that connect. That's why we scan ALL of the IPs between 1 and 255, or 1 to 254
Thanks for the vid I'm trying to learn but I'm still really confused ......anyway after checking how many devices are connected , How do you check what devices they are etc... ?
Hello Konrad. the simplest way of doing that would be to copy those IP addresses into a text file and run an Nmap scan using that text file as a source. I think this video will help you to achieve what you are looking for. Nmap gives an idea of the manufacturer if that's obvious by the MAC address. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qhCxKrU1AEY.html
Hi Trevor. I'm afraid I don't have time. I'll try to make more videos soon, but I'm busy writing a book at the moment ( not related to this topic). There are a lot of resources out there Trevor.
@@trevorunruh2000 no problem at all. FYI I've just made a couple of videos public, and there may be more to follow, that I recorded a couple of years ago while teaching Linux basics to a friend. They may be of interest - but only if you're at beginner level.
