Hey, Pekka, We will definitely do some testing on CentOS and try to reproduce these issues. Could you let us know which network driver you are using and whether you are running inside a VM or not?
As per the packaging, we are considering different a couple of different approaches to this and would love to hear feedback from everyone on here! - Should we take it out of tcpreplay into a separate repository and treat it like a separate entity to which tcpreplay can use if users want more speed (similarly to how netmap is done) - Or should we disable the quick_tx functionality by default to prevent issues with distros - Or something else? Okay everyone, let us know what you think the best approach is :) Thanks, Alexey -----Original Message----- From: Fred Klassen [mailto:fklas...@appneta.com] Sent: Wednesday, October 15, 2014 8:57 AM To: tcpreplay-users@lists.sourceforge.net Subject: Re: [Tcpreplay-users] Tcpreplay version 4.1.0 beta 1 released Thanks Pekka. Appreciate digging into this and I will look forward to any bug logs or patches. We generally don't test with CentOS. Primarily we do Ubuntu, but we will try to recreated. In the mean time, I have opened a bug on Ctrl-C. This one we should be able to fix without loading a new OS. https://github.com/appneta/tcpreplay/issues/144 Fred.
