1. 关于python写的代码

主要用于提取网页XML里内容，不是很完善，暂时能满足客户需求，需要改进的地方有出错处理和结构设计，函数应该都封装。

http://docs.python.org/2/library/index.html python还是有必要好好学一下，不能只为应付工作。

PYTHON库下载完tar包后解压完，进入目录执行python setup.py install.

2. 双控有10-G网卡，初始化时defaultIP读写错误

/home/walter/code/rasilient/base/RASOS/diskarray/local/etc/init.d/cfgsys（rc.da rc.sysinit） 

系统启动时根据niconf-0/niconf-1去写defaultip，这两个文件已经修改，但是测试发现没有写上去。在最新的KDI测试后发现能写上，所以把BUG给fix了。

纠结了好久的BUG7177

3. 关于ftp

1、检测是否安装了FTP:[root@localhost ~]# rpm -q vsftpd 

如果安装了会显示版本信息:

[root@localhost ~]# vsftpd-2.0.5-16.el5_5.1 

　　否则显示:[root@localhost ~]# package vsftpd is not installed 

　　2、如果没安装FTP，运行yum install vsftpd命令 

　　具体的细节如下：(如果无法更新，你先配置能访问互联网，我有文档叫 CentOS 在 VMware下，如何联网到Internet的解决办法 可以解决无法上网的问题) 

　　[root@localhost ~]# yum install vsftpd 

target上新建虚拟机上连不了外网阿。有待解决。

暂时就这样，以后每周小结一下。
