Hello all,
As new on HTB, I decided to take the starting point exercises to see the set up and not miss any tips. I do have some knowledge about Networking and tried to troubleshoot.
The target machine is not responsive.
Here is what I did:
- I used openvpn to connect with the downloaded config file
- Once connected and both in cli and webpage, I did an “> ip a”
- tun0 interface is up → 10.10.16.217/23
- I ping nexthop for test 10.10.16.1. It was reachable (I supposed it was nexthop)
- I tried to ping target IP (10.129.205.22 in that case). It didn’t work
- I checked IP route 10.129.0.0/16 routed via 10.10.16.1 as excpected and without overlap from other interfaces
- I tried to ping 10.129.0.1. It worked
- I tried nmap with -Pn option on target machine. All ports are filtered
- I tried to nmap -sV on a portion of target vlan and was able to see another machine (smb, netbios up, not telnet) I supposed it was there for someone else.
I tried several time, new openvpn, reset machine… no better results.
Maybe I missed the obvious.
Thanks in advance for your help
