I am having trouble setting capture filters, If I attempt to start ethereal capture and use the following string "ip proto sip" or "ether proto sip" or "proto sip" I recieve a etherreal error dialog box indicating "!Unable to parse filter string(unknown ip proto 'sip')" I have read the FAQ statement on "parse errors" and have the 2.3 version of WinPcap ( downloaded from  winpcap.polito.it as is suggested, I believe that I am using the correct syntax and have been able to set filters such as "src host 100.100.100.19" that work correctly, but no luck with filtering with protocols. Am i missing something? Please reply to Paul.meyer_jr@xxxxxxxxxxx
