debian 4.0下的dhcpd租约记录的差异问题

kevin.tan

在Debian 4.0平台，运行dhcpd server，如下:

1. 
   
2. debian:/var/lib/dhcp# ps aux|grep 'dhcpd'|grep -v 'grep'
   
3. root      2293  0.0  0.2   1756   584 ?        Ss   Oct04   0:00 /usr/sbin/dhcpd -q eth1
   
4. 
   

复制代码

有如下租约记录：

1. 
   
2. debian:/var/lib/dhcp# cat /var/lib/dhcp/dhcpd.leases
   
3. # All times in this file are in UTC (GMT), not your local timezone.   This is
   
4. # not a bug, so please don't ask about it.   There is no portable way to
   
5. # store leases in the local timezone, so please don't request this as a
   
6. # feature.   If this is inconvenient or confusing to you, we sincerely
   
7. # apologize.   Seriously, though - don't ask.
   
8. # The format of this file is documented in the dhcpd.leases(5) manual page.
   
9. 
   
10. lease 192.168.2.19 {
    
11.         starts 5 2007/10/05 09:14:28;
    
12.         ends 5 2007/10/05 09:24:28;
    
13.         hardware ethernet 00:e0:06:09:12:67;
    
14.         uid 01:00:e0:06:09:12:67;
    
15.         client-hostname "liang";
    
16. }
    
17. lease 192.168.2.13 {
    
18.         starts 5 2007/10/05 09:12:31;
    
19.         ends 5 2007/10/05 09:22:31;
    
20.         hardware ethernet 00:17:31:0d:4c:42;
    
21.         uid 01:00:17:31:0d:4c:42;
    
22.         client-hostname "Admin";
    
23. }
    
24. lease 192.168.2.23 {
    
25.         starts 5 2007/10/05 09:11:16;
    
26.         ends 5 2007/10/05 09:21:16;
    
27.         hardware ethernet 00:0b:6a:88:7c:cb;
    
28.         uid 01:00:0b:6a:88:7c:cb;
    
29.         client-hostname "hmjt-ad43d8e3bb";
    
30. }
    
31. 
    
32. ~
    
33.

问题是，在RH发行版下，租约记录为如下格式：

1. 
   
2. [root@Routed-Server ~]# less /var/lib/dhcp/dhcpd.leases
   
3. # All times in this file are in UTC (GMT), not your local timezone.   This is
   
4. # not a bug, so please don't ask about it.   There is no portable way to
   
5. # store leases in the local timezone, so please don't request this as a
   
6. # feature.   If this is inconvenient or confusing to you, we sincerely
   
7. # apologize.   Seriously, though - don't ask.
   
8. # The format of this file is documented in the dhcpd.leases(5) manual page.
   
9. # This lease file was written by isc-dhcp-V3.0.1
   
10. 
    
11. lease 192.168.2.125 {
    
12.   starts 2 2007/06/26 07:02:29;

# 如上图中红色所示，有什么在Debian的发行版下没有这些字段呢？另，在Debain下man dhcpd.leases ,man dhcpd.conf与RH发行版下也有差异，在RH下能用的一些参数在Debian下不能用了,比喻ddns-update-style
