Re: [Tcpreplay-users] Error message

I am rewriting in two steps. Replace lay two then replace layer 3. I am pretty sure I use --dlt=enet in the first. But I'll verify when I circle back report the exact steps I am using.

It's not that the pcap is invalid, it's that the Linux SLL tcpedit
plugin doesn't support writing.  Ie: you can read Linux SLL pcaps, but
you need to write them in a different format (such as EN10MB aka
Ethernet).  See the --dlt option in tcprewrite for a list of valid
output encapsulations.  Note that you may need to provide other
options in tcprewrite to do the conversion.
