[Winpcap-users] Filtering expression syntax

[Gianluca Varenni]

I would just write "icmp" or "ip and icmp"

  Hi.
   
  I'm using filtering expression syntax. And I was wondering why if a write: ip proto icmp in:
   
  pcap_compile(adhandle, &fcode, "ip proto icmp", 1, netmask) 
   
  is a invalid expression syntax. Which one is the correct form to filter icmp packets?
   
  Thanks in advanced.
