​thank you Michael
as you mentioned on the manual of installing bro on freebsd and on the bro
guide on the bro website i tried to install bro with netmap by
--with-netmap but there is no option for that so i installed bro and after
that i installed netmap plugin for bro from /aux/plugins/netmap​ folder and
after that everything is OK, and i also used Seth manual for configuring
node.cfg for workers,
thank you so much


*Regards,Iraj Norouzi*
