Hi all
can any body help me i am looking for TCP rotocol analysis toole such as measuring RTT ...
thanks

You can download the TCP analysis ruby tool from here : www.unleashnetworks.com/articles/tool-tcp-stream-analysis.html

This tool can estimate RTT based on initial handshake and the occasional delayed ACKs. All samples are plotted.

You need to download Ruby and have the capture file available in Unsniff format (*.USNF). You can convert any tcpdump file to Unsniff format by importing the file and saving it.


We will be integrating this tool in our next release. You can look at the \"Limited Beta Page\" menu on this site.

Hi,

Can you check if you have the fxruby gem installed ?

The command is \"gem list\"

Check if the output has fxruby in it.

I also uploaded a newer version with support for IPv6. Try downloading it again from www.unleashnetworks.com/lib/fileRead.php...=scriptlib/anastm.rb

(Make sure you press Ctrl-F5 to reload the script).

Good luck,

i downloaded the FXRUBY 1.16.13 also downloaded the updated file you mentioned

i need more help can you please tell me step by step instruction
