Except I measured an outgoing package.

How do I resend this package manually? (Unsniff)

I captured some packages. (TCP)

Now I want to select one or more packages to REsend them.

Exactly: I am looking for a Tool like \"tcpreplay\" in Unleash Unsniffer Software.

Can u help me?

If Unleash Unsniff does not support this feature.
Can u recomment other software that can do so? (for Windows XP)

Example: I RECEIVED a package from google.de =>
==============TCP-PACKAGE-BEGIN==============
TCP-Package-To: ME
TCP-Package-From: google.de
TCP-DATA: testtest
===============TCP-PACKAGE-END===============

Now I want to REDO this event (receiving the package) AGAIN.

Would be nice if someone can help me. TY

Hi Jens,

There is a windows port of tcpreplay you can try here sourceforge.net/project/showfiles.php?gr...mp;package_id=144474

We have not tried it, it might work.
Now I want to REDO this event (receiving the package) AGAIN.

Are you interested in simply playing back the TCP sessions from a client perspective ? This means just resending the old packets to google.de (in your example) or to some other IP address. You will not be able to establish a valid TCP connection because just playing back connections will not complete a TCP handshake. The SYN/ACK numbers will not be synchronized, the retransmissions, dupacks will also be out of sync.

We are going to support resending data from a client or server perspective in the next release. If you are interested we can send you a link to a private build.

Good Luck,
