大家好,又见面了,我是你们的朋友全栈君。

arping命令使用说明

BusyBox v1.17.3 (2011-07-20 17:01:30 CST) multi-call binary.

Usage: arping [-fqbDUA] [-c CNT] [-w TIMEOUT] [-I IFACE] [-s SRC_IP] DST_IP

Send ARP requests/replies

Options: -f Quit on first ARP reply -q Quiet -b Keep broadcasting, don’t go unicast -D Duplicated address detection mode -U Unsolicited ARP mode, update your neighbors -A ARP answer mode, update your neighbors -c N Stop after sending N ARP requests -w TIMEOUT Time to wait for ARP reply, seconds -I IFACE Interface to use (default eth0) -s SRC_IP Sender IP address DST_IP Target IP address

例如,要将接口ip广播给对端,可以发送免费arp请求,arping -I ethX -s x.x.x.x x.x.x.x,如命令中两个接口ip相同,即为发送免费arp请求;

同样,也可以用接口源ip去请求网关ip,避免对端学不到本端接口ip,命令 arping -I ethX -s x.x.x.x(接口ip) x.x.x.x(对端网关ip)

如要进行自动广播,可以考虑将命令写入到shell脚本中,如下:

#!/bin/sh

arping -I eth0 -c 1 -s 2.2.2.2 2.2.2.1 >/dev/null
