Capture MSN chats from others in the same LAN
Briefly, MSN Sniffer can capture MSN chats from the same PC. But it is easy to make it capture MSN chats from other computers in the same LAN. You can use a hub, or configure SPAN or port mirroring for your switch to forward a copy of each packet to your monitoring PC. If your switch can't configure, there are still several alternatives available:
- Execute the sniffer program on your Internet gatesway, router or proxy server if possible. Any Internet traffic will pass through the gatesway, therefore sniffer program could capture them.
- Send some fake ARP packet to your network to cheat your switch. And then switch will forward traffic to other computers to your computer. But it is an inefficient and dangerous way.
- Downgrade your top-level switch to a common hub. If your Internet bandwidth is less than 5M bps, downgrading will not have any negative impact on your Internet access. Please note most Internet bandwidth for home or company are less than 5M bps. Typical bandwidth are Dial-up(0.06M bps), DSL/Cable(0.4M bps), and T1(1.5M bps). Replace top-level switch with a hub as following diagram.
