Re: what does the TCP stream mean in wireshark

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

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?

Re: what does the TCP stream mean in wireshark

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

Re: what does the TCP stream mean in wireshark

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?

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

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

Re: what does the TCP stream mean in wireshark

Hi, I have a lot of pcap files and I encountered this phenomenon several days ago, it will be a bit hard for me to find it now. When I see such a case next time, I will send it to you, thanks!

Re: what does the TCP stream mean in wireshark

If you watch a given stream long enough, there will be connection re-use and you will see a sequence of connections.  Also, some windows boxes use TCP TIME-WAIT Assassination, which rapidly reuses tcp ports.  http://blogs.technet.com/b/networking/archive/2010/08/11/how-tcp-time-wait-assassination-works.aspx

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:
