Hi,
I’m experiencing some issues with the Challenge 1.3 and I’m stuck at “may take some time” (attached is the screenshot). Can someone navigate me how should I proceed? Thank you!
Hi @zhiyanski !
It looks like you’re creating your own top100.conf instead of using the one we provide in the /home/kali directory. That’s totally fine, but in that case, you’ll need to choose a different --adapter-ip since this Kali machine is on a different network (192.168.0.0/23 - the same one we’re scanning) than the Kali machine in the Guided Exercise (10.0.0.0/24).
In the provided top100.conf we use 192.168.0.75 (an unused IP on the local network), so I’ll suggest you use that. I’ve also added a note to the challenge that suggests the same.
Happy hacking!
Thank you for the help! Will now go through the challenge again.

Edit:
Found the solution!!! Thanks for all the help.
So now I am stuck on Task 3. I think I found the BIND one ( port 445), however I do not know how to go next. I tried the nmap several times now, but where should I add the Hint: The --dns-server option specifies the nameserver Nmap should use for reverse resolution.
Thank you.
Hey @zhiyanski
The <domain-or-ip> is a placeholder for your actual target (the address of the nameserver you discovered). For example, using your first command in that screenshot, if the IP address of the nameserver was 192.168.5.80, the command would be:
nmap -sL -iL ip.lst --dns-server 192.168.5.80
Hope this helps; good luck and have fun!
i have done machine part of 1.2 guided exercise but unable to answer tasks 1 and 2 and what i have to write in clipboard part of machine section
Hey there - could you please elaborate on the issue you’re having?
You should be submitting your answers through the Tasks tab. The Clipboard section of the Machines tab is used for submitting text to the virtual machine.
i am unable to answer tasks
If the fields on the Tasks tab are not accepting your answers, that likely means your answers are incorrect.
If this is unrelated to the NMAP lab, could you please create a new post and provide the exact name of the Course or Lab you’re working on, the exact lesson you’re working on, and a screenshot of the answers you’re trying to submit?
