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.

RFC2544 Compile help #135

Closed jlixfeld closed 8 years ago

jlixfeld commented 8 years ago

/disclaimer: Not a developer, so forgive my dumb questions...

Trying to compile the RFC2544 module, but it was giving me issues with lualib.h not being found. I ran make install in deps/luajit, but still couldn't fine the header. I modified the Makefile to add -I/usr/local/include/luajit-2.1 which got me closer, but seems there are issues still.

Any pointers?

Debian 8.4 MoonGen pulled from git last week.

You need the liblua-dev headers on your system in order to use the SNMP functionality of the RFC 2544 test.

However, you don't need to compile it to use the module - it will automatically select a different config module if the module isn't compiled. Devices that actually support all the necessary features via SNMP are rare anyways.
