<DIV style="FONT: 10pt arial"><B>Subject:</B> [Winpcap-users] Filtering
expression syntax</DIV>
<DIV><BR></DIV>Hi.<BR> <BR>I'm using filtering expression syntax. And I
was wondering why if a write: <STRONG>ip proto icmp
</STRONG>in:<BR> <BR><STRONG>pcap_compile(adhandle, &fcode, "ip proto
icmp", 1, netmask) </STRONG><BR> <BR>is a invalid expression syntax.
Which one is the correct form to filter icmp packets?<BR> <BR>Thanks in
advanced.<BR><BR>
