For every bug found in the softwre, there is a ugly man behind. For too many days! I’ve been working on that bug! And the software has already ran in a hotel! The only way that me can use to debug is using ssh plus vim. No other way. I cannot use gdb, Because that will let the clients unable to surf online. My program runs on a Linux router. Hang! Hang! There must be dead locks ! Where is it?! Then for many nights, I can’t sleep. Reviewing very code that acquiring locks. There is no mistake. =============================== I have to use gdb. Then re-ran my progrm in gdb. when it stopped response, I interrupt this stupid program. ….. strike! The error happens when doing libnet_init() It must not be libnet’s bug. ……… Finally, I knew what’s wrong. memcpy() param 3 too lengh , in the other file. and other thread.
