請教udhcpd(DHCP伺服)在2410開發版
本帖最后由 kalowt 于 2009-11-25 20:05 编辑核心系統是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)
# The start and end of the IP lease block
start 192.168.2.2 #default: 192.168.0.20
end 192.168.2.254 #default: 192.168.0.254
# The interface that udhcpd will use
interface eth1#default: eth0
# The maximim number of leases (includes addressesd reserved
# by OFFER's, DECLINE's, and ARP conficts
#max_leases 101 #default: 254
# If remaining is true (default), udhcpd will store the time
# remaining for each lease in the udhcpd leases file. This is
# for embedded systems that cannot keep time between reboots.
# 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)
# The amount of time that an IP will be reserved (leased) for if a
# DHCP decline message is received (seconds).
#decline_time 3600 #default: 3600 (1 hour)
# The amount of time that an IP will be reserved (leased) for if an
# ARP conflct occurs. (seconds
#conflict_time 3600 #default: 3600 (1 hour)
# How long an offered address is reserved (leased) in seconds
#offer_time 60 #default: 60 (1 minute)
# If a lease to be given is below this value, the full lease time is
# instead used (seconds).
#min_lease 60 #defult: 60
# The location of the leases file
lease_file /usr/local/etc/udhcpd.leases #defualt: /var/lib/misc/udhcpd.leases
# The location of the pid file
#pidfile /var/run/udhcpd.pid #default: /var/run/udhcpd.pid
# 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)
#notify_file dumpleases # <--- usefull for debugging
# The following are bootp specific options, setable by udhcpd.
#siaddr 192.168.0.22 #default: 0.0.0.0
#sname zorak #default: (none)
#boot_file /var/nfs_root #default: (none)
# The remainer of options are DHCP options and can be specifed 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
# lines. The only option with a default is 'lease'.
#Examles
opt dns 192.168.2.1
option subnet 255.255.255.0
opt router 192.168.2.1
#opt wins 192.168.2.1
#option dns 192.168.2.1 168.95.1.1 168.95.192.1 # appened to above DNS servers for a total of 3
#option domain local
#option lease 864000 # 10 days of seconds
###static_lease 08:08:08:08:27:12 192.168.104.104
# Currently supported options, for more info, see options.c
#opt subnet
#opt timezone
#opt router
#opt timesvr
#opt namesvr
#opt dns
#opt logsvr
#opt cookiesvr
#opt lprsvr
#opt bootsize
#opt domain
#opt swapsvr
#opt rootpath
#opt ipttl
#opt mtu
#opt broadcast
#opt wins
#opt lease
#opt ntpsrv
#opt tftp
#opt bootfile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 果然是高手
档我想看看合适参考发 绝对的高手 我自己研究下
