Linux за българи: Форуми

Здравейте защо като правя arping на заден хост  ми изкарва това
arp -A -I em1 -s 188.254.206.210
arp: illegal option -- A
usage: arp [-n] [-i interface] hostname
       arp [-n] [-i interface] -a
       arp -d hostname [pub]
       arp -d [-i interface] -a
       arp -s hostname ether_addr [temp] [reject | blackhole] [pub [only]]
       arp -S hostname ether_addr [temp] [reject | blackhole] [pub [only]]
       arp -f filename
root@r82-153:~# arping -A -I em0 188.254.206.210
arping.i386: illegal option -- A
Usage: arping [-q] [-Q] [-o timeout] [-c count] -i out_if_name \
   [-s source_mac] -S source_ip -t dest_mac -T dest_ip

-q quiet, prints only statistics
-Q super quiet, prints only alive/dead
-i interface - bpf hook (send/receive)
-s source_mac - mac adress for ether_shost and arp->sha,
      if not specified -i if's mac extracted and used
-S source ip for arp->spa
-t destination mac for ether_dhost and arp->tha
-T destination IP for arp->tpa
-o timeout for ecach packet, in miliseconds (default: 5, min: 1)
      waits atleast timeout for each packet, to detect duplicates,
       it is in mili(10^-6) seconds-c number of packets to send (default: 20, min: 1)
BUGS: currently it does not work with zerocopy bpf (net.bpf.zerocopy_enable) enabled

Във linuX!!!!

A Вие сте на freebsd доколкото мога да прочета.

да с freebsd сам

заради опцията -А

пробвай arping 188.254.206.210 -i em0 или em1 в посоката където е ипто
