Hi, I'm Aid, My tesbed: I run tcpreply on a PC1 (ubuntu 12.04 with Dell, i7 CPU, and 32 RAM, 1Gbps NIC) on eth0 which is connected to a Giga switch which forward the traffic (using port mirror) to another PC2 for traffic analysis. Pcap size: 11 GB
First, I run the following command tcpreplay -i eth0 -M 100 data.pcap Then after few seconds suddenly eth0 become down. I need to use ifdown and ifup then it works fine, then again down and so on. 1) What is the cause? and How to solve this issue? Then I run the following command (just add -K) tcpreplay -i eth0 -K -M 100 data.pcap It works and eth0 is not hanging, but RAM (with 32 GB although the pcap size is 11 GB) suddenly filled from 5 MB to 32 GB full and system hang (monitored by htop). 2) What is the cause? and How to solve this issue? I want to replay the pcap once only I hope someone answer the two questions above, thanks
