May 26 03:34:01 DHCP lease IP 192.168.0.103 to xue-370bc67673f 00-26-18-12-90-6e

这个要从下往上看,先看最下面一句
May 26 03:34:01 DHCP lease IP 192.168.0.103 to xue-370bc67673f 00-26-18-12-90-6e
这一句显然不是系统启动时的东西,因为系统已经能够正常工作并且可以分配DHCP客户地址.这一句的意思是5月26日26 03:34:01,DHCP服务为物理地址是00-26-18-12-90-6e,机器名是xue-370bc67673f 的设备分配了192.168.0.103 这个地址.这一句以后还要多次出现,再遇到就不解释了.而且,每一句前面都是日期和时间,也都不再说了.
往上看
May 26 03:34:03 WAN Dialup Try to establish PPPoE line
是外网口通过拔号尝试建立PPPOE连接.
May 26 03:34:09 PPPoE line connected
连接建立很快,6秒时间,两条日志之间的时间差是6秒,本句说PPPOE已经连接上了.
May 26 03:34:12 VPN (IPsec) Pass-Through enabled.
May 26 03:34:12 VPN (PPTP) Pass-Through enabled.
May 26 03:34:12 VPN (L2TP) Pass-Through enabled.
这三句是说,三种VPN方式被允许了：VPN (IPsec) 、VPN (PPTP)、VPN (L2TP).
May 26 03:34:12 RTSP ALG enabled.
实时流传输协议RTSP被允许通过,这个协议是对流媒体传送的.这个协议不熟,因此不知道ALG什么意思.
May 26 03:34:12 URL Blocking disabled.
这句应该是说禁止URL访问这个功能被禁止了,也就是说允许URL访问
May 26 03:34:12 Block WAN PING enabled.
禁止外网口的PING功能,也就是你PING它的广域网地址,是没有回应的.
May 26 03:34:12 Anti-spoofing disabled.
应该是反IP欺诈功能关闭了.
May 26 03:34:12 Remote management is disabled.
远程管理功能关闭
May 26 04:01:50 PPPoE Idle Timeout!Disconnect PPPoE line
PPPOE一直没有数据,超时了,PPPOE连接中断了.
May 26 04:02:49 WAN Dialup Try to establish PPPoE line
又尝试建立PPPOE连接
May 26 04:02:55 PPPoE line connected
又建立起来了.

这些前面都解释过了,不再多说了,再次注意,从下往上看.
May 26 06:06:19 DHCP lease IP 192.168.0.102 to WWW-0CE872D39A3 00-1d-60-51-59-8a
May 26 04:08:27 DHCP lease IP 192.168.0.100 to PC-201108210817 00-50-ba-26-2b-fc
分配了两个地址
May 26 06:29:33 Authentication Success 20-7c-8f-6a-6e-59
May 26 06:29:33 Authenticating.20-7c-8f-6a-6e-59
对20-7c-8f-6a-6e-59地址认证,认证成功,下面就要分配地址了.
May 26 06:29:37 DHCP lease IP 192.168.0.101 to MICROSOF-D984E2 20-7c-8f-6a-6e-59
分配成了
May 26 06:29:50 DHCP lease IP 192.168.0.101 to MICROSOF-D984E2 20-7c-8f-6a-6e-59
May 26 06:29:48 DHCP lease IP 192.168.0.101 to MICROSOF-D984E2 20-7c-8f-6a-6e-59
May 26 06:29:41 DHCP lease IP 192.168.0.101 to MICROSOF-D984E2 20-7c-8f-6a-6e-59
不知道是客户端的问题还是服务端的问题,这台机器不停的获取地址,时间间隔有7秒的,也有2秒的,也许是客户在操作什么.
