Change Ubuntu Window Manager from Metacity to Enlightment (E)

All the information about this transition are here:
http://packages.enlightenment.org/

Problem may be met:
1. Network manager
In Gnome, default network manager's package is "nm-applet". But under E, it is not be started by default.
So you can start it in terminal by hand, or you can change to a E network manager called "emodual-exalt" (short for "exalt").
Just "apt-get install" it.

Enjoy E.

Set DNS server in Ubuntu

DNS server IP is set in "/etc/resolv.conf", but if DHCP is used, the DNS server IP recieved from DHCP server will cover the config in "/etc/resolv.conf".

Caution: Dont define DNS server IP in "/etc/network/interfaces" like this:
===============
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
dns-search 192.168.1.1
===============
This will make you cant connect to the website using domain name, but only using IP address will connect to the website.

开始翻墙生活

就像某个blog说的，将来，访问访问互联网也是一种投资，你不但得为每月支付上网费用，还得为每天翻墙支付一定费用。

帮助软件通过ISA验证 - NTLMAPS

在配置文件里面设置好ISA的用户名和密码，

本地运行NTLMAPS服务在后台，使用默认端口5865，

最后浏览器代理设置为127.0.0.1：5865

httptunnel配置成功

server：运行svn server，使用8080端口，防火墙只开放80端口。IP为1.2.3.4。
Client：通过浏览器访问不了server的8080端口。

解决：

下载http://www.nocrew.org/software/httptunnel.html

把压缩包里面"cvs20040323"目录下的：
cygwin1.dll
hts.exe
htc.exe

都放到server/client的"C:\windows"下面。

Server：cmd运行"hts -F 127.0.0.1:8080 80"
Client：cmd运行"htc -F 8888 1.2.3.4:80"

这个时候用浏览器访问：http://127.0.0.1:8888就相当于访问1.2.3.4没有开放的8080端口了，也就是svn服务了。

如果你是内网用户如何轻松获取自己公网IP

如果你是内网用户（通过NAT或者Route连接因特网），那么最快获得公网IP的方式就是：

$ GET http://www.whatismyip.org/

如果你用浏览器登录www.whatismyip.org的时候，你也会发现，其实整个网站的作用就是获取你的公网IP，首页除了IP没有任何其他内容了。
