Basically I am trying the same command, but on a layer 2 capture instead of a layer 3 capture. So I tried: tcprewrite --portmap=67:68 --infile=input.pcap --outfile=output.pcap It did not give me any kind of error message, but when I open the new output file in Wireshark, I don't see all udp ports set to 68. ----- Original Message ----- From: "Aaron Turner" <synfina...@gmail.com> To: "Main forum for tcpreplay" <tcpreplay-users@lists.sourceforge.net> Sent: Wednesday, April 01, 2009 4:11 PM Subject: Re: [Tcpreplay-users] How to Re-map layer 2 TCP/UDP Ports On Wed, Apr 1, 2009 at 12:42 PM, Owen K. <owenkor...@comcast.net> wrote: > On a layer 3 trace (Wireshark), I can re-map the UDP ports from 67 to 68 > without a problem using the following command: > > tcprewrite --portmap=67:68 --infile=input.pcap --outfile=output.pcap > > However, I am having difficulty using the same tcprewrite command to > change > a layer 2 capture.
