Long story short I'm testing something and trying to figure out how to view VPN data (the default server/client setup through Windows) using Wireshark. In my test environment I've got Wireshark running on both the server and the client but I only see PPTP traffic.
I've got all credential information for the VPN (obviously) but I haven't found any way to view the decrypted traffic. I found a link that said it couldn't be done on Windows 7 but I'm running XP atm.
I found the answer to this question on the Wireshark Q&A so for anyone who has this problem in the future I solved it by install Netmon on both boxes. After that the VPN interface was available for Wireshark to sniff.

I set up my own VPN by installing OpenVPN on a Ubuntu server, then I download client.ovpn file from Ubuntu server to my Windows laptop. And then, I import that client.ovpn to OpenVPN GUI app on Windows and finally, I connect to my Ubuntu VPN server and everything work fine.
I installed OpenVPN on Ubuntu server using this instruction: https://github.com/angristan/openvpn-install
So i think traffic flow will be like this:
My computer (browser,...) --> Ubuntu OpenVPN server --> Internet.
My question is does OpenVPN GUI encrypt traffic between my computer to Ubuntu OpenVPN server?
And as always, thank you so much.
Yes, the point of OpenVPN is that the traffic is encrypted (unless you disable all security in the server's config file) between the client (your Windows laptop) and the Ubuntu Server. Your traffic to the internet is not encrypted though. You'd best use Tor if you want to hide your IP Address online.
ISPs as of 2020 use deep pack sniffers which although can't read the information can easily log source and destination. They do that to prioritize traffic. If you are able to change your IP on the fly that might buy you a couple of hours but in the end they choose how much and how long you can maintain that connection at the speed you want no matter what is advertised. If you have large files to move and are not happy with the speed your best bet is to experiment with different times of the day. ISP leaves that option open for those who move a lot of data. My window of opportunity is between 4:00 am and noon. That could vary based on geographic location. Streaming services have tasked servers quite a bit in the last decade.
I have vpn connection in my laptop. I am able to ping the vpn ip address successfully. I would like to analyze the network traffic and packets to and from vpn.So, I installed sharkwire But I dont see the listing of either VPN Name or the IP Address of VPN in wireshark. Any help?
Wireshark uses WinPcap on Windows, and some third-party VPN software doesn't work with WinPcap and even some standard VPN software might not work with WinPcap. That might be the problem.
You could try installing Npcap and, if Wireshark uses it, that might fix the problem. As its main page says, report problems on Nmap's GitHub issues page.
I am doing malware analysis of a pdf file in windows vm. This malicious pdf file is going to connect to the internet and I don't want it to. But I want to see the network activity it is going to do.
I watched in a video that I can connect the windows vm to some other vm like remnux and test the packets being sent through wireshark.
If somebody wants to watch the video I am talking about here is the link: -https://www.youtube.com/watch?v=kNlRDNt7Zp0
She talks about the remnux thing in between 15:00 to 16:00 min. I don't understand how she did that.
Can somebody please explain me how those steps are done. I have searching the net all day but I can't find anything. I am really a beginner in all that networking stuff so any topics I did find were just jargon to me.
Thank you for your help.
I am using VMware player version 7.
Edit: I did do a lot of research on this topic but whatever is available on google is far too much for me to understand. Please don't think that I didn't try anything myself.
Malware is likely to generate a DNS request to resolve the ip of the C&C server. Therefore you can set the DNS in the victim (windows) machine to the ip address of the remnux machine and you will get the DNS request generated by the malware. You can then configure remnux to direct the malware to the same remnux machine to monitor traffic generated by malware when it tries to connect to C&C server after DNS resolution.
You may have to write a custom server for responding to the malware request. Modern malware use RSA challenge which will almost render initiating communication impossible.

I have a puzzle I am not able to figure out, I would appreciate any help.
I am connected to a remote desktop using windows default remote desktop utility (Windows 8 locally, Windows 7 remotely).
The remote desktop is not in the same sub-network as my own.
Connection is made through default port 3389. Using Wireshark locally I can confirm the TCP connection being established and the data flow.
Running Wireshark in the remote desktop, I don`t see any flow of data between the two computers.
If I send a ICMP ping from the remote desktop to my computer, it works well and I can see it in Wireshark both remotely as well as locally. But if I send the ICMP ping from my computer to the remote desktop, it fails. I see it leaving my computer through Wireshark, but it never reaches the remote desktop (I don`t see it in Wireshark).
I don't think it is a firewall issue (specially since it can't explain why Wireshark won`t capture the port 3389 RPC flow).
Does anyone have any idea of what might be going on?
I found the main issue.
In Wireshark, turns out it is possible to configure the capture interface with a filter.
To change it, go to: Capture->Interfaces
On the interface being used, stop capturing to enable the Options, there it is possible to configure a capture filter.
I have a real IP. Or so I think, basically how I tested this is under windows in cmd I pinged my IP address and I got packages back, so that must mean it's real. However when I start my xampp and go to my IP address in the browser I get
Unable to connect
Firefox can't establish a connection to the server
I tried looking up other questions but they didn't help cause all answers I found were suggesting LAN connection. Can you please explain to me any extra steps I need to take or link an answer that does that. Thanks!
The only way to access your localhost from other computers is over a Local Area Network (LAN); whether wired or wireless, there has to be a physical connection between the computers.
Once the computers are connected, you can access your localhost from the browser with the name of the computer on other computers:
http ://your-computer/path/to/files/
It also works on the same computer, so you can test it there.
You can find the name of your computer by going to the "Network" section in Windows Explorer.
EDIT:
If you want to access a localhost from a computer that is on another network, you have to create a web server; more or less what you would be paying for from a hosting company. Here is how you would do it:
