Nmap scans section 101 - 102

when i type the exact same commands into the pwnbox parot for nmap i do not get the same results. infact for example at the top of page of 102 enumeration it has example window and shows all sorts of thing open. however when i try
sudo nmap 10.129.2.28 --top-ports=10
just like they did and got results here is what i get.
sudo nmap 10.129.2.28 -v --top-ports=10

here is what they got in their example:

..........
why is this and is anyone else getting this result.  the openvpn is already active in the pwnbox so its not that. and nowhere did they say to execute any differentcommands.  am i missing something?  So going on to all the examples and trying them has the same results. The examples show ports to be open but when i execute same commands and IP i get filtered status

Hi Will26254,
I think you need spawn new target. when you spawn the new target, you will have new target IP address. Right under the Question section, you should find Target: Click here to spawn the target system.

no sir this is acadamy. and there is no place on the page to spawn. sections 101-102 before you get down to the target. same thing in section 101 except there is no target . the page before this has no target to spawn

I am on HTB Academy as well. Normally, at the end of a lesson when you have practice questions, there will be option to spawn a target. If you don’t see an option to spawn a target, which mean at that lesson, HTB don’t have practice questions for you just yet.
