Sniffer for Windows NT.

["SATEESHB" <SATEESHB @ inf . com>]

     Hi All,
     
       I want to know is there a package that allowes me to set TCP/IP mode 
     to promiscous.Or any package that allowes me to dump the TCP/IP 
     packets that are passing through my machine.It is required as I want 
     to get a hang of TCP/IP traffic.It will be helpful if I can get a 
     source code also.
     
     This is just to know about sniffing.I have no dreams of misusing this.
     (Even if I do, it is of no use.I am inside a firewall and I don't have 
     access to internet except SMTP)
     
     
     The OS I am using is Windows NT and Network card is Intel Ether 
     Express.
     
     Regards,
     Sateesh
