Wireshark-users: Re: [Wireshark-users] [TCP segment of a reassembled PDU] question...
JV, Abhik
I found the following, hope that helps:
(I used this filter because I assume this is between host and the
appropriate server: ip.addr==10.200.50.111 && ip.addr==208.109.181.58 )
I think the server is not slow, because in packet 7-8-9-10 (use my
filter) the IP IDs are 13908 13909 13910 13911 so I think that means
that the server in not busy, because it is sending you continuous IP
IDs. If the server would have been busy (eg serving other clients at the
same time) IP IDs would have been like 13908-14258-15689-16898...
TCP receive window size is also OK.
Maybe need some Apache fine-tuning ???

Regarding your question on [TCP segment of a reassembled PDU], please
see the following links:

http://wiki.wireshark.org/TCP_Reassembly
Any information in the packet details pane which is enclosed in
brackets ([...]) is usually Wireshark generated information.
Regarding the slow response, perhaps the server was really busy, but
maybe someone is able to provide a better explanation.

ok guys I've been getting lots of [TCP segment of a reassembled PDU]
when trying to access my website, I fired up wireshark when noticed that
it took a long time for my website to load, and after capturing for a
while I noticed that after the 3 way handshake and the initial GET
request issued by the browser the web server took 17 seconds to
responds, as you can see in the attached capture file, and after that
time the server started to respond with [TCP segment of a reassembled
PDU], and this only happened with this particular website, as I tried
other and they loaded just find, anyway what exactly this [TCP segment
of a reassembled PDU] means or when something like this happen?... I
google for this and all I found was users modifying the settings for the
PDU on the registry... in my case I'm using a Linux machine although I
tried from a windows box with the same results.
any comments welcome!
thanks
