Mac OS X中的DHCP设置

Question

Mac OS X中的DHCP设置是否有任何命令行界面？我发现在System Profiler中,Network选项卡提供了很多有用的信息,但我没有找到任何有关任何命令行等效的文档.

Answer 1

你可以用

networksetup -listallnetworkservices
networksetup -getinfo <networkservice>
networksetup -setdhcp <networkservice> [clientid]

networkservice就像以太网(第一个命令列出的所有可用)

Answer 2

您还可以使用:

ipconfig getpacket `interface`

接口将在哪里en0, en1等

即:

ipconfig getpacket en1
op = BOOTREPLY
htype = 1
flags = 0
hlen = 6
hops = 0
xid = 215448168
secs = 3
ciaddr = 0.0.0.0
yiaddr = 192.168.15.121
siaddr = 0.0.0.0
giaddr = 0.0.0.0
chaddr = 0:19:e3:6:70:95
sname = 
file = 
options:
Options count is 8
dhcp_message_type (uint8): ACK 0x5
server_identifier (ip): 192.168.15.1
lease_time (uint32): 0xa8c0
subnet_mask (ip): 255.255.255.0
router (ip_mult): {192.168.15.1}
domain_name_server (ip_mult): {192.168.15.249, 192.168.15.240}
domain_name (string): domain.com
end (none): 

你也可以这样做:

ipconfig getoption en0 optionname

即: ipconfig getoption en1 router

192.168.15.1
