周末小记

周末和老婆去三里屯看了《非诚勿扰》，台词的彩头较多，剧情较差，140分钟有些太长了。有个笑场的地方是，葛尤说了一句：”孽缘啊！”，本不可乐，但是影院里有个小孩重复了这句话，一个童音版的话外音引得大家暴乐。从影院出来就去了Apple Store，老婆看上了MacBook Air和iPod Touch，我依然对MacBook Pro心往神怡，新的unibody做工真是不可同日而语。质感！质感！无奈手中拮据，不能立时拍下这三样，日后一一置办吧！

在FreeBSD和Linux路由表里标记的差异

对比一下FreeBSD和Linux的关于路由表Flags的定义
相同的有

U   Up: The route is active.
H   Host: The route destination is a single host.
G   Gateway: Send anything for this destination on to this remote system, which will figure out from there where to send it.

FreeBSD独有的:

S   Static: This route was configured manually, not automatically generated by the system.
C   Clone: Generates a new route based upon this route for machines we connect to. This type of route is normally used for local networks.
W   WasCloned: Indicated a route that was auto-configured based upon a local area network (Clone) route.
L   Link: Route involves references to Ethernet hardware.

Linux独有的：

R (reinstate route for dynamic routing)
D (dynamically installed by daemon or redirect)
M (modified from routing daemon or redirect)
A (installed by addrconf)
C (cache entry)
!  (reject route)

FreeBSD里常看到的是UC, UHLW, UGS, UGHS这几种。UC根据本地网络配置自动生成的，UHLW是由UC根据连接情况自动生成的，UGS是手工配置的段网关路由，UGHS是手工配置的主机网关路由。

Linux里常看到的是U, UG, UGH这几种。U和BSD的UC是一样的，UG和UGS一样，UGH和UGHS一样，没有UHLW。

BSD明确区别了手工添加和自动生成，Linux则没有。还是BSD强大呀，XD
