Hi,
My local IP of htb is down
Regards

I think HTB has been having network issues today. Try reconnecting.
If 10.10.14.8 is your IP the ping results might be a bit weird at the best of times though.
It’s been a month same issue 
Ok, I would try some other troubleshooting measures, like I said, pinging your VPN IP isn’t ideal because it’s not immediately obvious what route the traffic will take.
What other problems are you experiencing? It is easier to troubleshoot between you and a remote system.
for now, the only problem is that the local IP is not alive!
I am not sure what you mean by the local IP is not alive?
If you can connect to HTB boxes and do all the normal things, then I don’t get what it is you are trying to solve? What do you want the local IP to do?
When you run traceroute 10.10.14.8 what does it show?
Have you confirmed that is your HTB IP address?
Hi,
I mean that this IP 10.10.14.8 is dead when I ping this IP, its not working, I am not getting any reverse shell because it’s dead, but when I connect to the VPN, machines are working but this IP is dead 10.10.14.8

Hi,
Have you confirmed that is your HTB IP address?
Check out the above pic, you can see the HTB IP (connected to the VPN)
checked with ifconfig too = inet 10.10.14.8 → 10.10.14.8 netmask

Ok - so to double check my understanding:
You are trying to send traffic from a HTB box to your machine but not getting anything? Is that correct?
What are you running on your local machine which you expect to respond to the shell or the pings? The IP address is clearly not dead, it is just that you aren’t getting a response because there may be nothing to respond.
Most OSes will drop ICMP traffic to themselves and if you have any security tooling in place it will block this.
So, rather than try to send ICMP packets from your IP to your IP, it is better to try and look at what is going on.
Open three terminal windows.
In one run nc -nklvp 7811 -e /bin/bash
In the second run tcpdump -nnv port 7811 (or tcpdump -nnv port 7811 -w capture.pcap if you want to store it in a file)
In the third run nc 10.10.14.8 7811
If you get a shell, everything is working as normal. If you don’t, check to see if you get any traffic being logged in the second window.
Hi,
python -m SimpleHTTPServer 1337
when the IP is on listening using Netcat, I tried even with the curl no response on the listening

What does TCPDump show?
Failing anything useful in TCPdump, I’d suggest:
- Disconnect from the VPN and check your IP address
- Run the tests on your non OpenVPN IP
- Connect the VPN and corroborate the IP you get on your machine with the one on the HTB Access page (Login :: Hack The Box :: Penetration Testing Labs)
From there, you really need to be able to send packets from some other machine to your IP to test if it is working. There are lots of weird things if you try to send packets to yourself over a VPN which makes the findings inconclusive - and emphasises the value of checking the raw packet data in Wireshark/TShark.
Hi,
I checked my local machine IP without the VPN, that IP is working perfectly but when I connect to the VPN, HTB box IP is not responding like the local machine IP without the VPN, Same IP 10.10.14.8 is working cool in the PwnBox
Kindly check out the difference
PwnBox (HTB) VS VPN
PwnBox
VPN

Although this is probably quite frustrating, I’d suggest trying to test one thing at a time rather than several and you need tcpdump looking at every connection
-
Are you getting the same IP in pwnbox as you get on Kali over VPN? I’ve never used pwnbox so I don’t know if that is normal.
-
The TCP dump screenshot show traffic is flowing to your listener. If your listener isn’t seeing this is almost certainly down to something like a firewall or other ACL type control. It might be worth double checking that the listener was configured.
If you are on the VPN and you run python -m SimpleHTTPServer 80 or python3 -m http.server 80 then connect to http://localhost/ does it work?

yes IP is the same
This works but issue is that I can’t download anything into the vulr machine in the HTB machines; I tried to download a file into the machine but its not possible with the http://localhost/ so this should be HTTP://10.10.14.8 because I tried the same int he pwnbox which works there

I get that isn’t a solution but you need to eliminate issues on your machine. The chances are high that the cause of this problem is:
- your connection isn’t working and you need to download a new connection pack.
- servers on your machine aren’t working
- security on your machine is blocking the inbound traffic from the VPN
In the unlikely event that you can eliminate all three, then something at HTB has broken - but it is strange that only your IP address is affected. In this case you need to raise a Jira ticket.
Hi,
I tried tryhackme vpn that’s working fine there is no issue with that VPN from the first day I am having issues with the HTB VPN, I downloaded both free and paid VPN non of works fine, I don’t know what’s the problem.

If you have Free account, the VIP VPN wont work. If you have a VIP account, the VIP VPN should work and if you can connect to remote systems it is working.
The VPN is just a tunnel. Its a way of putting your machine into a remote environment. At the risk of over generalising, all it means is that packets go along that path rather than the one from your machine to the internet.
If you cant access services on your machine from the VPN then something is probably wrong on your machine. Rather than trying lots of different things, you need to try some individual tests and work out what the answer means.
For example:
- With no VPN, spin up a webserver, and in a browser visit http://localhost/. Check what it looks like in TCPDump
- Open the HTB VPN, spin up a webserver, and in a browser visit http://localhost/. Check what it looks like in TCPDump
- Try visiting http://YOURHTBIP/ and see if the TCP traffic looks different.
It sounds tedious but troubleshooting requires a fair amount of methodological checking if you want to find out where the problem is.
I’d also suggest downloading a different connection pack or switching servers just to see - At the very least you’d be able to try a different IP address.
Other things to consider:
- Double check that you don’t have an IP conflict with your local network.
- make sure your interfaces are correct (tun0 vs eth0 vs ens33 etc)
- check your firewall status
- check if you have any security tools intercepting traffic
