arpd 命令是用来收集免费 arp 信息的一个守护进程，它将收集到的信息保存在磁盘上或者在需要时，提供给内核用户用于避免多余广播。
arpd [ -lkh? ] [ -a N ] [ -b dbase ] [-B number] [ -f file ] [-n time] [-R rate] [ interfaces ]
-l：将arp数据库输出到标准输出设备显示并退出； -f：指定读取和加载arpd数据库的文本文件，文件的格式与“-l”输出信息类似； -b：指定arpd数据库文件，默认的位置为“/var/lib/arpd.db”； -a：指定目标被认为死掉前查询的次数； -k：禁止通过内核发送广播查询； -n：设定缓冲失效时间。
网络接口：指定网络接口。
启动 arpd 进程：
[root@Dev_Test ~]$arpd -b /Data/webapps/test.db
运行一段时间后，查看结果：
[root@Dev_Test ~]$arpd -l #需要指定db位置 db_open: No such file or directory #指定刚才的 db 位置 [root@Dev_Test ~]$arpd -l -b /Data/webapps/test.db #Ifindex IP MAC 3 10.20.32.51 f8:c3:9e:4e:5b:da 3 10.20.32.71 40:31:3c:18:a7:98 3 10.20.32.77 90:2b:d2:70:81:46 3 10.20.32.101 40:31:3c:18:b0:44 3 10.20.32.105 a8:c8:3a:4c:97:12 3 10.20.32.123 78:02:f8:f6:7d:df 3 10.20.32.131 40:31:3c:18:af:d4 3 10.20.32.171 40:31:3c:18:a8:84 3 10.20.32.181 bc:3d:85:65:3b:31 3 10.20.32.205 6c:b7:49:64:f9:be 3 10.20.40.21 38:d5:47:ac:2a:61 3 10.20.40.25 38:d5:47:ac:ea:2a 3 10.20.40.107 fa:16:3e:c6:3a:6f 3 10.20.40.167 52:54:00:e3:0b:51 3 10.20.32.34 50:01:d9:d6:71:7d 3 10.20.32.102 40:31:3c:18:b2:14 3 10.20.32.152 7c:11:cb:37:e1:47 3 10.20.32.180 40:31:3c:18:b0:38 3 10.20.32.196 10:6f:3f:29:46:89 3 10.20.32.202 FAILED: 44sec ago 3 10.20.32.204 54:25:ea:74:46:40 3 10.20.32.236 40:31:3c:18:b0:70 3 10.20.32.246 50:01:d9:dc:cb:a7 3 10.20.32.254 00:e0:8d:03:fc:4e 3 10.20.40.20 38:d5:47:ac:e9:ee 3 10.20.40.24 38:d5:47:ab:4d:32 3 10.20.40.106 fa:16:3e:13:df:36 3 10.20.40.114 FAILED: 44sec ago 3 10.20.40.116 FAILED: 44sec ago 3 10.20.40.166 52:54:00:19:8e:30 3 10.20.40.168 FAILED: 44sec ago
