Как мога да видя IP.

[Networker]

В примера не, но и със затрит кеш пак става:

arp -ad 10.20.10.5

arping -i eth2 00:0E:16:56:78:AB

ARPING 00:0E:16:56:78:AB

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=0 time=1.261 msec

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=256 time=2.221 msec

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=512 time=6.933 msec

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=768 time=2.861 msec

След arping, запис за 10.20.10.5 продължава да няма:

arp 10.20.10.5

Address HWtype HWaddress Flags Mask Iface

10.20.10.5 (incomplete) eth2

С прост скрипт за затриване на целия кеш отново дава инфо за IP:

for i in `awk -F ' ' '{ if ( $1 ~ /[0-9{1,3}].[0-9{1,3}].[0-9{1,3}].[0-9{1,3}]/ ) print $1 }' /proc/net/arp` ; do arp -d $i ; done

arping -i eth2 00:0E:16:56:78:AB

ARPING 00:0E:16:56:78:AB

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=0 time=1.867 msec

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=256 time=2.441 msec

60 bytes from 10.20.10.5 (00:0e:16:56:78:ab): icmp_seq=512 time=2.213 msec
