Hello. I found wonderful bug in arpd daemon of iproute2 package. Somehow arpd is absolute unworkable if run program with -f flag. On my amd64 server i got "Segmentation fault" regardless -f mac-list.txt file content. The source of misc/arpd.c is not hard and i found that cause of this bug is commit dd50247dba85255538d659551305b4bb75bcae62. I'm not c++ developer, but i suppose segfault occured because argument of dbase->put() has non-initialized dbdat.data argument. Also arpd.c has strange condition "if (do_load || do_list)" that not allows to run program with -f argument. I did pull out the hexstring_a2n function from utils.c of previous commit aeb199d5ce86c6c72decaac333cad5a7d7b38b3a and used it to populate dbdat.data value after which program works fine. I hurriedly make the patch that makes program alive. Please inspect this problem, fix this bug and test program with -f key. PS: sorry for my english =)
