Yes - they're in the ANSI C standard, so if you don't have them you're
using a really old crufty platform.

Yes, exactly.

TCPINDEX
Tcpindex captures packets from a LAN and indexes all of the strings from those
packets in an inverted index so they can be efficiently searched using
keywords. Think of it like a simple search engine for packets across the
network.
Tcpindex was developed as an experiment in w

Yeah! You´re right!
Dumping packets via tcpdump to file, I can choose packet and cut out payload
starting from 0x0042
Therefore It could be done via dd utility and some scripting avoiding
libpcap.
Via tcpflow I can dump sessions. That´s more convenient.
Thanks in advance!

No, tcpdump by itself can't. But that's what tcpflow does.

Thank you. I´ll try.
I think, I found what´s going on.
I´ve read manual more accurately and found, that -w key writes WHOLE
packets, NOT payloads.
And now my question is:
can tcpdump extract payloads from packets, or it just extracting headers?

You might want to look at tcpflow:
http://www.circlemud.org/~jelson/software/tcpflow/
By ´raw´ data I mean collected binary data from the payloads.
Wireshark does correctly restore binary stream from payloads.
I don´t know how to do this via tcpdump (if it possible off course)
I did extract HTTP reply as binary stream. Divided it with hexedit to
text data (header) and binary data (
