好方便啊，呵呵：）

到官方下载最新flash play:

搞定。

    在程序中使用配置文件来灵活的配置一些参数是一件很常见的事情，配置文件的解析并不复杂，在python里更是如此，在官方发布的库中就包含有做这件事情的库，那就是ConfigParser，这里简单的做一些介绍。
    ConfigParser解析的配置文件的格式比较象ini的配置文件格式，就是文件中由多个section构成，每个section下又有多个配置项，比如：

    假设上面的配置文件的名字为test.conf。里面包含两个section,一个是db, 另一个是concurrent, db里面还包含有4项，concurrent里面有两项。这里来做做解析：
#-*- encoding: gb2312 -*- import ConfigParser import string, os, sys cf = ConfigParser.ConfigParser() cf.read("test.conf") # 返回所有的section s = cf.sections() print 'section:', s o = cf.options("db") print 'options:', o v = cf.items("db") print 'db:', v print '-'*60 #可以按照类型读取出来 db_host = cf.get("db", "db_host") db_port = cf.getint("db", "db_port") db_user = cf.get("db", "db_user") db_pass = cf.get("db", "db_pass") # 返回的是整型的 threads = cf.getint("concurrent", "thread") processors = cf.getint("concurrent", "processor") print "db_host:", db_host print "db_port:", db_port print "db_user:", db_user print "db_pass:", db_pass print "thread:", threads print "processor:", processors #修改一个值，再写回去 cf.set("db", "db_pass", "zhaowei") cf.write(open("test.conf", "w"))

Hyperlinks
AppSnap displays the website of an application amongst other details. It would be ideal to open the link in the default browser when clicked. Luckily for us, wxPython has a widget just for this.

Let’s create a hyperlink:

# Create hyperlink on an existing panel widget
link = wx.lib.hyperlink.HyperLinkCtrl(parent=panel, pos=(225, 60))

For starters, let’s initialize the link.

# Initialize the hyperlink
link.SetURL(URL=”)
link.SetLabel(label=”)
link.SetToolTipString(tip=”)

* BridgeModule -- Allows for simple network bridge management
-------------------------------------------------------------
功能：操作网桥
方法：
list() Returns a dictionary containing the bridges and their connected interfaces.
add_bridge(brname) Creates a new bridge named brname.
add_interface(brname, ifname) Adds interface ifname to bridge brname.
delete_bridge(brname) Deletes bridge brname.
delete_interface(brname, ifname) Removes interface ifname from bridge brname.
add_promisc_bridge(brname, ifname) Creates a new bridge brname, attaches interface ifname to it and sets the MAC address of the connected interface to FE:FF:FF:FF:FF:FF, so traffic can flow freely through the bridge. This is required for use with Xen.
up_bridge(brname) Marks bridge brname and all it's connected interfaces as up.
down_bridge(brname) Marks bridge brname and all it's connected interfaces as down
-------------------------------------------------------------

一、故障现象
1、在客户端安装好func及certmaster，配好certmaster参数。
2、service funcd start，端口及进程都起来了。
3、在certmaster server 运行certmaster-ca --list死活看不到客户端的主机名。
排查过程
1、将certmaster的主机名换成IP，无效。
2、更新客户端的func及certmaster版本，无效。
3、运行/usr/bin/certmaster-request，提示：socket.error: (111, 'Connection refused')，将certmaster修改成localhost就正常了。原因可以就在这里，因为certmaster是双向的，发现在/etc/hosts中有主机名指向127.0.0.1，此时连接不上certmaster server了。将/etc/hosts中的主机名删除，再用/usr/bin/certmaster-request来测试连接，成功！！在certmaster也能看到主机了，大功告成。

二、故障现象
#/usr/local/bin/certmaster-request 被控端证书请求
certificate does not match key (run certmaster-ca --clean first?)

排查过程
1、删除/etc/pki/certmaster/证书文件再试，无效
2、分别重启certmaster、funcd服务，无效
3、删除服务器证书文件.cert后再请求正常。
原因为主机名称发生变更时服务器端certmaster-ca -c "servername"没有成功删除.cert文件导致。

二、后续问题
1、ImportError: No module named dbm (NetSeek提供)
解决：
yum -y install gdbm gdbm-devel
