Good afternoon.

Guys, I’m developing a java application for capturing packages using JPCAP. I am using a virtual machine, but I am not able to select the network interface for my program to capture the network packets. Is there any way to do this using the virtual machine? I tested the code on the local machine and it is working as desired.

In short, it would be the use of JPCAP in Virtualbox.

Thank you.

In the virtual machine’s network settings, select that it must be connected in bridge mode, so it will have its own ip inside your network.

  • I’ve done it. However I can’t capture any network packets.

  • I was able to solve the problem. The card identifier used by Virtualbox is 0 (zero). Jpcapcaptor captor = Jpcapcaptor.openDevice(interfaces[0], 65535, false, 200);
