Ubuntu Usage Record

使用Ubuntu有一段时间了，也重装了好一次，server也用的是Ubuntu，也重新部署过几次，记录下一些需要的东西，以后可以按照流程走下来，不至于用到什么再去搜索安装。

Update source

首先安装好系统后要更新源，使用国内的一些源，下载源文件，或者自己搜索添加一些国内的源，更新源文件，然后update/upgrade即可。可以从这里直接下载源文件：https://gitee.com/youdias/UseUbuntu/blob/master/sources.list

Desktop view real-time speed

对于桌面版，可以通过安装indicator-sysmonitor实时监控网速：

···
sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
sudo apt-get update

sudo apt-get install Indicator-sysmonitor
Indicator-sysmonitor &
···
Can be activated at the start of network monitoring, while also monitoring the use of Cpu/mem, by right-click to set the boot, by adding net:{net} to see the speed of real-time

Server Edition speed limit

对于server，流量是很宝贵的，为了防止有些人扫描代理等窃用，可以通过软件对网速进行限制，当自己在使用时取消网速限制，当不用时开启限制，即使连上来了也不至于造成太大的损失，对于云服务器如AWS来说，甚至可以更激进一点，设置一个禁止任何链接的安全组，当不用时候网络采用该安全组，进一步保护server流量。首先需要安装软件wondershaper：

···
sudo apt-get install Wondershaper
···
Easy to use, open limit:
···
$ sudo wondershaper eth0 100 20//Set download speed 100kb/s, upload speed 20kb/s
···
Cancellation Restrictions:
···
$ sudo wondershaper clear em1
···
The interface name can be obtained using Ubuntu AutoComplete, such as input tcpdump-i e +tab, which automatically complements the full interface name, or is viewed through ifconfig.
More convenient, you can write the opening/cancellation limit of two SH script, only need to run, you can download directly here in Https://gitee.com/youdias/UseUbuntu/tree/master/NetControll, Put it in the right place in the server
Add execute permissions, and then you can set the speed by scripting.
