核心系統是linux(非uclinux)
2410有一個網卡eth0(外網)
我另裝上一個usb有線網卡作為eth1來當dhcp伺服器
# Sample udhcpd configuration file (/etc/udhcpd.conf)

# If remaining is true (default), udhcpd will store the time
# remaining for each lease in the udhcpd leases file. This is

# If you set remaining to no, the absolute time that the lease
# expires at will be stored in the dhcpd.leases file.
#remaining yes #default: yes
# The time period at which udhcpd will write out a dhcpd.leases
# file. If this is 0, udhcpd will never automatically write a
# lease file. (specified in seconds)
#auto_time 7200 #default: 7200 (2 hours)

# Everytime udhcpd writes a leases file, the below script will be called.
# Useful for writing the lease file to flash every few hours.
#notify_file #default: (no script)

第一次啟動dhcp，eth1的網卡ip是設定成192.168.2.1(在/etc/rc.d/rc.inet1.conf改)確定動起來後，dhcp設定檔如上
我的dhcp啟動指令是/usr/sbin/udhcpd -fS /usr/local/etc/udhcpd.eth1.conf
ok~~dhcp功能可以正常配給WINXP電腦網卡(IP和DNS都設定自動取得)得到192.168.2.2
目前很正常
問題來了
我現在把eth1網卡ip是設定成192.168.3.1(在/etc/rc.d/rc.inet1.conf改)，/etc/rc.d/rc.inet1 restart確定動起來後，dhcp設定檔把192.168.2.....都改成了192.168.3.....
我先關掉dhcp指令是killall udhcpd，/etc/rc.d/rc.inet1 restart確定動起來後，然後一樣啟動dhcp指令是/usr/sbin/udhcpd -fS /usr/local/etc/udhcpd.eth1.conf
但在winxp電腦網卡(IP和DNS都設定自動取得)按右鍵選"修復"卻不能得到192.168.3.2~192.168.3.254的IP，而是出現Windows無法完成修復這個問題， : 因為無法完成下列動作：更新您的IP位址
而我試過一些ip分享器產品或adsl數據機開dhcp功能可以修復成功得到ip說，所以覺得是不是哪裡有問題?
而且發現如果真要得到ip，要把開發版手動撥開關重開機(不能reboot)，或是在winxp電腦網卡按右鍵停用=>啟用，以上兩種方法可以取得ip
