[Winpcap-users] Filtering on offline PCAP file

[cycl0ne dude]

hi guys, 

im having trouble on how to filter an offline PCAP file.

its like: noob.exe -r input-big.cap -w smtp-only.cap <filter>

where <filter> is a bpf to filter out all SMTP packets from offline
pcap file "input-big.cap", and save all the filtered or output packets to
"smtp-only.cap" file.

any help?

thanks.
