Interface Switching Not Working (Only eth0 Captures)

[x9xhack]

Description: When using the f key to switch interfaces, the app only captures packets from eth0. Selecting other interfaces has no effect.

Steps to Reproduce:

Press f to change the network interface. Select a different interface (e.g., tun0). Capture continues on eth0.

Expected Behavior: Packet capture should work on the selected interface.

Actual Behavior: Only eth0 captures packets, other interfaces are ignored.

Hi @Chleba,

Thank you for the fix.

It still doesn't work for me. Am I doing something wrong?

Hi @x9xhack,

Could you give me more details please ? What OS ? Is the packets from eth0 stop when you switch your interface (that should definitely happen). Is the second interface some virtual interface ? Just more details please.

Hi

OS: Kali Rolling 2025-1, running in a VM with VMware. tun0 is the OpenVPN virtual interface.

Hi @x9xhack, Please tell me if packet dump logs will stop from eth0 when you switch interface to tun0. Also is there some traffic from tun0 interface ? Thanks.

Hi @Chleba

1 - Yes, packet dumps stop for eth0 when switching the interface to tun0 2 - Yes , there is traffic for tun0. ( tested with curl , ping , nmap port scan )
