Re: [Tcpreplay-users] Interface become down and RAM issue when run tcpreply

Yes, I agree with Aaron. It is difficult to imagine tcpreplay being the cause of the memory leak when using PF_PACKET. How are you seeing the memory leak? Are you using “top”? If so, can you send me a screen capture that includes the offending process? Also, please have a look at either syslog

Re: [Tcpreplay-users] problem: tcpreplay using netmap

You did what I was just about to suggest. You must see netmap in your “tcpreplay -V”. Are you sure that netmap module is loaded? Do “lsmod” to ensure it is there. If not, install it with insmod. Fred. > On Jul 30, 2015, at 12:41 PM, Pedro Neves wrote: > > I found the problem. > --with-netmap

Re: [Tcpreplay-users] problem: tcpreplay using netmap

Unfortunately, this seems to happen a lot with netmap. Their API has no backward compatibility. I have asked them to be careful with this in the past, but it appears that their new version no longer works with anything older. Therefore, I either have to write a version of tcpreplay for every versio

It sounds as though something is not installed properly on your target machine. Did you build on one machine and run on another? Normally "configure" will detect if a prereq is not installed. Check to ensure that "libpcap", "libpcap-dev", "flex" and "bison" are installed. Fred. > On Feb 29, 201

Re: [Tcpreplay-users] Flow replay

I believe you want to send a pcap file to a server and have the server respond. This can only be done if the sequence numbers are altered from the original pcap file, based on the response from the server. To do that, you need to run 'tcpliveplay'. Fred. > On Apr 26, 2017, at 8:05 AM, Álvaro
