Many if not all network traffic capture utilities require that the network adapter has the promiscuous mode enabled.
To check if the promiscuous mode is on run:
Kernel Interface table
Iface MTU RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg
eth0 9001 9095 0 0 0 10367 0 0 0 BMRU
Look at the Flg column – if the P flag is missing the mode is not enabled.
To enable it run:
ifconfig eth0 promisc
ip link set eth0 promisc on
Good Post on Debian network configuration with examples:
ifstat – InterFace STATistics Monitoring
ifstat is a tool to report network interfaces bandwith just like vmstat/iostat do for other system counters. It can monitor local interfaces by polling the kernel counters, or remote hosts interfaces using SNMP.
To install run:
apt-get install ifstat
then just issue:
KB/s in KB/s out

..you need to tell Windows 7 that you want to use the machine as a file server and that it should allocate resources accordingly.
Set the following registry key to ‘1′:
HKLMSYSTEMCurrentControlSetControlSession ManagerMemory ManagementLargeSystemCache
and set the following registry key to ‘3′:
After changing the two registry settings, I simply restarted the “Server” service in Windows 7 and now the sharing is working fine.
