我必须在基于Linux的电路板和主机（它可以是WinXP/Win7/Ubuntu等）之间建立一个RNDIS连接。基于Linux的USB小工具设备的静态主机RNDIS IP
当我使用RNDIS电缆连接主板时，所有主机都能识别并开始解析IP地址。在主板方面我给一个静态IP通过启动
ifconfig usb0 169.254.1.1 netmask 255.255.0.0 up
执行命令，但主机需要很长的时间来谈判RNDIS IP每一次出现一些不可预知的IP，如169.254.abc.xyz。
我想为连接到此Linux板的任何主机分配一个静态RNDIS IP（例如169.254.1.2）。有人能帮我确定我能做到吗？在主机端，我不使用任何特殊的RNDIS驱动程序。默认的USB-Ethernet驱动程序被下载。 Linux版本是2.3.62。
好的..我得到了答案....其实我们必须通过接口usb0启动一个DHCP服务器。因此，无论何时USB主机将尝试寻找DHCP IP，在设备上运行的DHCP服务器以及在USB接口上列出的DHCP服务器都将应答呼叫并分配一个IP。要解决一个IP只是IP池assing OLY一个IP（可以在udhcpd.conf文件中完成）
启动服务器udhcpd为：
busybox udhcpd /etc/udhcpd.conf
下面的dhcpd.conf其中的样品我使用：
# Sample udhcpd configuration file (/etc/udhcpd.conf)
# Values shown are defaults
# The start and end of the IP lease block
start 169.254.10.102
end 169.254.10.102
# The interface that udhcpd will use
interface usb0
# The maximum number of leases (includes addresses reserved
# by OFFER's, DECLINE's, and ARP conflicts). Will be corrected
# if it's bigger than IP lease block, but it ok to make it
# smaller than lease block.
#max_leases 254
# The amount of time that an IP will be reserved (leased to nobody)
# if a DHCP decline message is received (seconds)
#decline_time 3600
# The amount of time that an IP will be reserved
# if an ARP conflict occurs (seconds)
#conflict_time 3600
# How long an offered address is reserved (seconds)
#offer_time 60
# If client asks for lease below this value, it will be rounded up
# to this value (seconds)
#min_lease 60
# The location of the pid file
#pidfile /var/run/udhcpd.pid
# The location of the leases file
#lease_file /var/lib/misc/udhcpd.leases
# The time period at which udhcpd will write out leases file.
# If this is 0, udhcpd will never automatically write leases file.
# Specified in seconds.
#auto_time 7200
# Every time udhcpd writes a leases file, the below script will be called
#notify_file # default: no script
#notify_file dumpleases # useful for debugging
# The following are bootp specific options
# next server to use in bootstrap
#siaddr 192.168.0.22 # default: 0.0.0.0 (none)
# tftp server name

# The remainder of options are DHCP options and can be specified with the
# keyword 'opt' or 'option'. If an option can take multiple items, such
# as the dns option, they can be listed on the same line, or multiple

而测试一些时间udhcpd服务器抛出错误。所以我没有做任何改变。首先创建/var/lib/misc/udhcpd.lease文件ADN我修改conf文件为：
# Sample udhcpd configuration file (/etc/udhcpd.conf)
# Values shown are defaults
# The start and end of the IP lease block
start 169.254.10.102
end 169.254.10.103
# The interface that udhcpd will use
interface usb0
# The maximum number of leases (includes addresses reserved
# by OFFER's, DECLINE's, and ARP conflicts). Will be corrected
# if it's bigger than IP lease block, but it ok to make it
# smaller than lease block.

其实我是想给与static_lease叫一切连接给它相同的固定IP，但不能得逞IP 。
