p1p1 is some weird redhat/Dell naming thing. I've seen it before for ethernet devices.
I believe line 555 should be: errx(1, "%s is not a valid Tcpreplay character device", device); That said, any chance you're running tcpreplay from /dev or something? I'm trying to figure out why line 549 is returning 0 (the call to stat()). Try running tcpreplay in another directory so it can't find /dev/p1p1 (or any file called p1p1 in the local directory), because it looks like it's finding a file called 'p1p1' and realizing it's not a khial device, aborting. -- Aaron Turner http://synfin.net/ Twitter: @synfinatic Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. -- Benjamin Franklin On Sat, Mar 8, 2014 at 1:50 PM, Fred Klassen <fklas...@appneta.com> wrote: > Seth, I'm not sure why this message typed out strangely.
