[Winpcap-users] Newbie facing problem in setting filter while running pf.exe

[chitra .R]

Hi Winpcap users,
   
    I have installed Winpcap 4.0.2 and trying the examples given. I am facing problem executing pf.exe. I am not able to set filter expression for capturing packet from a specified machine giving the IP address. I would like to capture icmp reply packet from host having IP address 10.4.102.110 what is the filter syntax i should give.
  I tried giving 
  pf.exe -f icmp src net 10.4.102.110 
  but I get icmp reply from other source as well like 10.4.102.139.
   
  Can anyone help me regarding this.
   
   
  Thanks & Regards,
  Chitra
