When installed on Windows XP or earlier, it will install the legacy WinPcap driver. http://www.bleepingcomputer.com/forums/t/470852/computer-will-recieve-packets-but-not-send-them/
BleepingComputer is being sued by Enigma Software because of a negative review of SpyHunter. This means it is unable to synchronize Syn/Ack's to create valid TCP sessions. SCSI disks with a good controller should provide the best performance, since they generally require the CPU to do less work. Since tcpreplay is not multi-threaded, SMP or dual-core processors won't help very much.
Since the loopback interface doesn't use an ethernet L2 header, the IP stack of the operating system is unable to parse the packet and deliver it to the listening daemon. If this buffer is full, the kernel is supposed to tell tcpreplay that it didn't copy the packet to this buffer. Q: Does tcpreplay support dual NIC's like Tomahawk? Tcpdump The solution is to configure the bnx2x driver with multi_mode=0.
timeout was 2 seconds. The only way to use IPTables or Traffic Control (tc) with tcpreplay is to run tcpreplay on a different box and send the traffic through the system running iptables/tc.

Hence, your OS kernel implementation of writing to raw sockets is one of the most important aspects since that is where tcpreplay spends most of it's time. http://tcpreplay.synfin.net/wiki/FAQ The solution is to use: ./configure --disable-local-libopts --disable-libopts-install Q: Issues with autogen/libopts The Tcpreplay suite uses the GNU Autogen/libops library. Microsoft Message Analyzer If your computer is busy running a bunch of other processes (running X, downloading mail, etc) then it will impact tcpreplay's performance and ability to time packets correctly. Wireshark Alternatively, you can specify the tcpreplay-edit --mtu-trunc option - packets will be truncated to the MTU size, the checksums will be fixed and then sent.
It's a timely guide that any network administrator will come to rely on. http://sonoportal.net/cannot-send/cannot-send-job-to-mom-state-pre-run.html Im trying to do this when i have downtime. Compiling Tcpreplay Are there binaries available for XXX operating system? Performance will depend on options selected, pcap file and hardware. Tshark
Note: Tcpreplay no longer supports libnet!

Usually this is a problem with the network card, driver or OS kernel which may or may not be fixable.
Note: Tcpreplay no longer supports libnet! Can I use non-pcap capture files? This turns out to be a limitation of the loopback interface on many operating systems. This makes development much easier, but not without some cost.
Can I cite email communication in my thesis/paper? One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS.If you work with Cisco routers, it's likely that you deal with If you choose to participate, the online survey will be presented to you when you leave the Technet Web site.Would you like to participate? navigate here Currently we are not aware of any OS kernels with this bug, but it is possible that it exists.
First, if performance is important to you, then upgrading to tcpreplay 3.x is worthwhile since it is more optimized then the 2.x series. Upgrade to a later release of the Libnet library to solve this problem. Please check the name and try again. Edited by hamluis, 05 October 2012 - 02:12 PM.
If by server you mean a daemon (Unix) or service (Windows) which listens on a port (a web or mail server would be common examples), then try tcpliveplay.
