MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control.

Cannot replay the pcap file in loop mode #296

Closed LibinLiu0189 closed 2 years ago

LibinLiu0189 commented 3 years ago

I use the latest MoonGen version and meet the same problem. It cannot solve the problem using the solution below.

$ sudo ./build/MoonGen ./examples/pcap/replay-pcap.lua 0 trace/caida16.pcap -r 1 -l Like the command above, I run it and only the first time, the trace is played according to the pcap file, in the following, the sending rate is 0 Mbps and not packets are sent.

Could you help check this? Thanks.

Fix that. Change line 65 from "if rateLimiter then" to "if rateLimiter and n > 0 then".

Do I need to set the prev back to 0 while resetting pcap file?
