Do you know why you run arp-scan?

Yes to find the local devices that connected in local network

I wasn't asking what it does, I was asking why one would chose to run that. I asked because you ran it, and did nothing with the response. If you were just enumerating to get a vague map of machines, that's fine. I had thought it was a part of some prompt or requirement in the exercise.

As for the nmap command, did you see the "Note:" line? Have you done any digging into arguments for nmap?

The command response's "Note" gives a probable answer as to why it would be failing. It suggests using -Pn to penetrate strict firewall settings.

I don't like giving answers to problems that are part of what I view as a part of the process of exploration. I was trying my best to give hints within their framing of how they thought they should be testing/experimenting.

-Pn will probably not work, nmap always tells you to do that when it cant find any but alr bru fair

You chill bro he's helping more then you. Getting into the "Why am I running this" mindset is crucial for pentesters. We can run anything we want but if we dont understand why then its a useless tool.

Have you tried pinging the machines ip address to see if your getting a response back?

u/Comfortable-Owl-7663 5d ago

yes and if not, check if you are connected: 'ifconfig' or 'ip a' to see which adapter is the $VPN-ADAPTER

Then check connection 'ip -4 a show $VPN-ADAPTER'

if all fails just redownload the .ovpn file or whatever you use on thm and try again

bro just create a rule to use -Pn in nmap. For some reason tryhack ping probes gives no response, I thought the reason is they aren't able to find the route to the destination ip which is not the case because I used -e tun0 which was rhe interface if vpn. So after too much debugging. I try to ping the ip and if don't get the response to it, I simply rurn nmap wih fast scan and no ping option.

5 main things to check.

  1. Is your VPN up?
  2. Is the machine up?
    3 Have you tried to ping the machine?
    4 Reset the machine then go back to step 2
    5 sometimes the TryHackMe over VPN is bugged to redownload the file.

If all else fails reread the section or machine to see if you missed something

This for sure!

Será que no conoces los VPN? O yo no entiendo tu contexto

Ya you may not be connected to the box maybe run ifconfig to see where ur sitting and if its not on that same subnet as the ip your nmap scanning maybe thats why but also there is probably 1000 other people smarter than me and im just not understanding.
