Error message

raw socket handles error:%s

What it means

activateRawSocket collects per-interface SocketHandle errors and, when no interface produced a working raw socket, returns this aggregated error with all the underlying messages — raw capture cannot start.

Solutions

1. Read the aggregated inner errors for the real cause per interface
2. Run as root or with CAP_NET_RAW so AF_PACKET sockets can be opened
3. Verify interface names and Linux kernel support for TPACKET_V2
