It was precisely designed for this purpose, create a network capture from a single process (and its children) without leaking other traffic. Capture from either end of the veth interface and start your process within the network namespace.įor the latter approach, I wrote some scripts to automate it, it can be found at.

On Linux, create an isolated network namespace and use a virtual Ethernet (veth) pair to connect the new network namespace with the main network namespace.

Run a program in a virtual machine (VM) and capture traffic from within the VM, or from the bridge attached to the outside of the VM.

If you know that an application contacts certain IP addresses or ports, you could specify a capture filter such as udp port 53 or host.

For established TCP sockets, this information could potentially be looked up on-the-fly, but there is no way to express a capture filter to limit filtering to a single process. Or skip this step if you only want to sniff traffic from the app to your own computer.

Here are the steps: Connect your Mac to your router using an Ethernet cable (the Wi-Fi card will be busy working as access point).

Capture files from HTTP traffic By using Wireshark we can also easily extract files such as images, documents and audio files from the network traffic. Arbitrary packets are typically not associated with a process. An alternative is using your Mac as a Wi-Fi access point and sniffing the traffic with TCPDump. Sniffing a session cookie from the network has practically the same impact as sniffing credentials.
