packet capturing from a file

[Junktyz]

Hello,

with pcap I can sniff on a network interface. The interface I want to sniff on I take with

dev = pcap_lookupdev(errbuf);

But now I already have a dump file from tcpdump and so my programm (including pcap.h) should read from this file instead of sniffing on an interface.

Does somebody know how I have to go on?

edit: Oh, I see, there is an extra discussion board for network problems. If it's neccessery, can a mod move this thread.

This is in the pcap manual.

Oh really? I thought I watched this. I have to look into the man tomorrow again.

Thank ya.

Oh I found it .

It's the

pcap_open_offline()

function.

Thank you for the the advise to watch the man pages again ^^.
