have tcpdump show the 'conversation' as i would get from wireshark?
2
Is it possible to get the same output i would get from:
tcpdump port 80 -w log.pcap
wireshark log.pcap
in wireshark Analyze > Follow TCP Stream and then in the bottom drop down Entire Conversation
but without using wireshark? ideally using tcpdump or other widely available tool (netcat?) in the console.

Are you opposed to using Wireshark from the console by its self? You could eliminate tcpdump.

my bad if i make this seems like a matter of GUI vs console. The only issue with wireshark is that it's not widely available. i'd love for that to not be the case, but often, when i'm debugging something, the machine rarely has (or i can install) wireshark. This question is to try to add another 'tool' to my tool box. right now i do the slow process of using tcpdump to capture, scp somewhere, open with wireshark. it's too slow. ofcourse, if i could have wireshark in the first box, the problem would be solved.

Newer versions of TShark should support "-z follow" for this:
−z follow,prot,mode,filter[,range]
Displays the contents of a TCP or UDP stream between two nodes.
The data sent by the second node is prefixed with a tab to
differentiate it from the data sent by the first node.
prot specifies the transport protocol. It can be one of:
tcp TCP
udp UDP
ssl SSL
mode specifies the output mode. It can be one of:
ascii ASCII output with dots for non‐printable characters
hex Hexadecimal and ASCII data with offsets
raw Hexadecimal data
Since the output in ascii mode may contain newlines, the length
of each section of output plus a newline precedes each section
of output.
filter specifies the stream to be displayed. UDP streams are
selected with IP address plus port pairs. TCP streams are
selected with either the stream index or IP address plus port
pairs. For example:
ip−addr0:port0,ip−addr1:port1
tcp‐stream‐index
range optionally specifies which "chunks" of the stream should
be displayed.
Example: −z "follow,tcp,hex,1" will display the contents of the
first TCP stream in "hex" format.
===================================================================
Follow: tcp,hex
Filter: tcp.stream eq 1
Node 0: 200.57.7.197:32891
Node 1: 200.57.7.198:2906
00000000 00 00 00 22 00 00 00 07 00 0a 85 02 07 e9 00 02 ...".... ........

00000000 00 01 00 00 ....
00000026 00 02 00 00
Example: −z
"follow,tcp,ascii,200.57.7.197:32891,200.57.7.198:2906" will
display the contents of a TCP stream between 200.57.7.197 port
32891 and 200.57.7.98 port 2906.
===================================================================
Follow: tcp,ascii
Filter: (ommitted for readability)

Node 1: 200.57.7.198:2906
