The problem, in a nutshell:
# tcpreplay -t -i p1p1 big.pcap
Fatal Error:
%s is not a valid Tcpreplay character device
Two issues.
(1) This seems to have intended to be routed through a printf function,
but doesn¹t seem to be (see missing args below).
(2) It doesn¹t work, whereas old tcpreplay 3.4.4 works fine.
This problem seems independent of the pcap file specified.
It has been reproduced on a different CentOS 6.5 system, but with 똪o¹,
and with a more recent kernel.
Yes, I am root (uid=0). No, SELinux is not running.
Any thoughts? Details follow ...
Thanks for any help you can offer.
kind regards,
Seth
