Optimize iptables reject rules

We always use this rule to notice a interloper that the service was prohibited.
-A INPUT -j REJECT --reject-with icmp-host-prohibited
But, I think it's better to disguise the rejection as no service, rather than notice a interloper there was a service you cannot reache.
-A INPUT -p tcp -j REJECT --reject-with tcp-reset
-A INPUT -p udp -j REJECT --reject-with icmp-port-unreachable
-A INPUT -j REJECT --reject-with icmp-host-prohibited

[Quoted] VNC from boot on Ubuntu 12.04 without logging in, using LightDM and x11vnc

Quoted: http://seb.so/vnc-from-boot-without-logging-in-ubuntu-lubuntu-xubuntu-and-mint-lmde/

Instructions

LightDM apparently supports a VNC server out of the box; however, it’s designed to work with tightvncserver (or similar) which create separate X sessions (the 2nd lot of VNC servers I mentioned above) so not quite what we’re after1.
Ubuntu derivatives use Upstart (upstart.ubuntu.com) to manage startup processes - LightDM (and GDM!) creates a login-session-start event when the display manager is up (i.e. when X is all loaded, but before you’ve logged in) so we’ll create an upstart job that listens for that, and starts a VNC server on the existing X session, allowing connections before login.

Get exFat support for Ubuntu 10.04 LTS.

Get fuse-exfat
$ sudo add-apt-reprository ppa:relan/exfat
$ sudo apt-get update
$ sudo apt-get install fuse-exfat

Create mount point.
$ sudo mkdir /media/Data

Manually mount:
$ sudo mount -t exfat-fuse /dev/sda6 /media/Data
umount:
$ sudo umount /media/Data

Automatically mount (by edit fstab):
$ sudo gedit /etc/fstab
add new line
/dev/sda6 /media/Data exfat-fuse defaults 0 0
save and restart.

*1 '/dev/sda6' is Device ID, could be '/dev/sdXX', such as '/dev/sdb1', please check in Disk Utility.
*2 Someone says, update util-linux-ng 2.17 to 2.18, ubuntu will identify exfat automatically, but still need fuse-exfat. (actually not test)

大陆视频网站土豆（tudou.com）、优酷（youku.com）、迅雷看看（kankan.xunlei.com）对部分视频做了IP限制。

下面使用Firefox的FoxyProxy插件欺骗IP检测。
优点是：只用代理欺骗IP检测页，不会因为免费代理速度过慢影响网页浏览及视频播放。
