Name
frdev - A high efficient ip black/white list firewall (work as a linux kernel module).
Some details could get from here.
Usage:
make
bash install_frdev.sh
ls -hl /dev/frdev*
gcc fripadm_black_in_exe.c -o fripadm_black_in_exe
gcc fripadm_white_in_exe.c -o fripadm_white_in_exe
ping 192.168.31.100
bash fripadm_black_in.sh insert '192.168.31.100 8.8.8.8 1.100-1.*.1'
bash fripadm_black_in.sh switch
bash fripadm_black_in.sh dump
bash fripadm_white_in.sh insert '192.168.31.100 8.8.8.8 '
bash fripadm_white_in.sh switch
bash fripadm_white_in.sh dump
# # do what you want now :)
bash unstall_frdev.shNotes:
The little patch below will solve the compiling problem in 3.10.0-327.el7.x86_64 (because of the recently kernel updates).
