Installing netmap in FreeBSD Try to build kernel module for current kernel: ```bash cd /usr/src/sys/modules/netmap make make install kldload netmap ``` But you could hit this bug: ```bash KLD netmap.ko: depends on kernel - not available or version mismatch linker_load_file: Unsupported file type ``` Enable netmap startup on server load: ```bash echo 'netmap_load="YES"' >> /boot/loader.conf ``` To activate Netmap on your server you have to turn your interface on promiscuous mode: ifconfig promisc And should rebuild kernel manually. Install SVN: ```bash pkg install devel/subversion ``` Download base repository for FreeBSD 10 stable (replace 10 by your FreeBSD version): ```svn checkput https://svn0.ru.freebsd.org/base/stable/10 /usr/src``` Build and install new kernel: ```bash cd /usr/src/sys/amd64/conf cp GENERIC KERNELWITHNETMAP cd /usr/src make buildkernel KERNCONF=KERNELWITHNETMAP make installkernel KERNCONF=KERNELWITHNETMAP ```
