Re: what does the TCP stream mean in wireshark

Version 1.6.6 should make a distinction between two sessions with the same ip/port combinations. Are you able to post 
the file here (if not to big) or else create a bug-report on bugs.wireshark.org? You can also mail me directly if you 
want to limit the exposure of the file.

Cheers,
Sake

Those sessions should be treated as separate. This has been implemented a few years ago already. Which version of 
Wireshark are you using?

I used a mobile browser in a HTC smartphone to access some websites and I
used wireshark to capture the packets between the mobile browser and the
website servers.

Multiple handshakes wherein the same source & destination ports were re-used?

Were that packets of a cheap embeded device? Sounds like a buggy TCP stack
to me.

Thanks! But previously I saw a tcp stream where there are several TCP
connections (I mean mutiple SYN-SYN/ACK-ACK handshakes)

Nangergong,

A TCP stream is a single connection between two IP addresses, between the
two same ports. If you see the beginning you'll see the SYN-SYN/ACK-ACK
handshake, an will also see the sequence numbers increasing. Some protocols
like HTTP/1.1 can have multiple higher level conversations on the one
connection, so I am not sure that is what you might be seeing?

HI, all:

    In wireshark there is an option "Follow the TCP stream", I'm
wondering what does it mean? it seems that in such a TCP stream there are
multiple TCP connections.
