Silvi,

I believe you should try the latest version, 4.0.5, available here  
http://tcpreplay.appneta.com/wiki/installation.html This may not be a tcpreplay 
problem. The version of libpcap used may be coming into play.

Fred.

Subject: [Tcpreplay-users] tcp replay cant send file with packets anomalies on 
version 3.4.4 when in the past it could (2.3.5)

Hi
I am testing device that supposed to detect when packet with anomaly is sent to 
it (all kind of anomalies)
I am trying to send packet using TCP replay that has bogus ip length (attaching 
it)
In the past I used tcp replay of version 2.3.5 on mandriva I had no problem 
sending this cap file
But now I am using tcp replay of version 3.4.4 on Ubuntu trying to send (or 
manipulate the file using tcpprep) the same exactly file I get the following 
error:
Fatal Error in tcpreplay.c:replay_file() line 252:
Error opening pcap file: truncated dump file; tried to read 4 file header 
bytes, only got 0

And unable to send or manipulate the file

Is there some workaround I can tell the tcpprep or tcpreplay ignore those 
problems in the capture?

Regards,
Silvi.
