Hi there.
I was busy these days for finding a way for high speed traffic generation
and at the last found that tcpreplay maybe the only choose.
I have a virtual switch (openvswitch to be exact) and some virtual hosts
connected to it by veth pairs.
I have successfully build tcpreplay with netmap and quick-tx support.
output of tcpreplay -V :
tcpreplay version: 4.1.0 (build git:v4.1.0)
Copyright 2013-2014 by Fred Klassen <tcpreplay at appneta dot com> -
AppNeta Inc.
Copyright 2000-2012 by Aaron Turner <aturner at synfin dot net>
The entire Tcpreplay Suite is licensed under the GPLv3
Cache file supported: 04
Compiled against libdnet: 1.12
Compiled against libpcap: 1.6.2
64 bit packet counters: enabled
Verbose printing via tcpdump: enabled
Packet editing: disabled
Fragroute engine: enabled
Default injection method: pcap_inject()
Optional injection method: Quick TX
Optional injection method: netmap
but when trying to send traffic with these modes i get these errors :
./tcpreplay -i "h1-eth0" -K -t --loop 50000 --netmap bigFlows.pcap
Switching network driver for h1 to netmap bypass mode...
Fatal Error: failed to open device h1-eth0: Failure accessing netmap.
Request for netmap version 11 failed.
Compiled netmap driver is version 11.
Error=No such device or address
./tcpreplay -i "h1-eth0" -K -t --loop 50000 --quick-tx bigFlows.pcap
Fatal Error: failed to open device h1-eth0: [quick_tx] error while opening
device
Check that the QuickTX module is loaded and the interface name is correct
Quick-tx and netmap and veth all are loaded and listed by lsmod.
Can anybody help me and tell what's wrong? or suggest me a high speed
solution or option? I really really need this.
