ubuntu 14.04/ubuntu 17.10做主机双网卡共享上网(NAT)

需求是电脑通过无线上网，然后把有线共享给其他设备，其他设备通过电脑代理上网。

电脑上有两张网卡，一张有线网卡，名字为eth0,一张无线网卡，名字为wlan0。

电脑的有线网卡配置的静态IP地址为：192.168.0.1。

对于Ubuntu 16.10/17.10系统，请参考 Ubuntu 16.10/17.10无法通过/etc/rc.local开机启动应用激活系统对于/etc/rc.local功能的支持。

电脑上执行如下命令：

$ echo "1" | sudo tee /proc/sys/net/ipv4/ip_forward

$ sudo iptables -F

$ sudo iptables -P INPUT ACCEPT

$ sudo iptables -P FORWARD ACCEPT

#打开NAT,无线网卡这里大eth0改wlan0
$ sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE 

#保存设置信息，下次开机自动开启代理
$ sudo sed -i '$a\net.ipv4.ip_forward = 1' /etc/sysctl.conf

$ sudo sed -i '$a\iptables -F' /etc/rc.local

$ sudo sed -i '$a\iptables -P INPUT ACCEPT' /etc/rc.local

$ sudo sed -i '$a\iptables -P FORWARD ACCEPT' /etc/rc.local

$ sudo sed -i '$a\iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE' /etc/rc.local

$ echo "1" | sudo tee /proc/sys/net/ipv4/ip_forward

$ sudo iptables -F

$ sudo iptables -P INPUT ACCEPT

$ sudo iptables -P FORWARD ACCEPT

#打开NAT,无线网卡这里大eth0改wlan0

$ sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

#保存设置信息，下次开机自动开启代理

$ sudo sed -i '$a\net.ipv4.ip_forward = 1' /etc/sysctl.conf

$ sudo sed -i '$a\iptables -F' /etc/rc.local

$ sudo sed -i '$a\iptables -P INPUT ACCEPT' /etc/rc.local

$ sudo sed -i '$a\iptables -P FORWARD ACCEPT' /etc/rc.local

$ sudo sed -i '$a\iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE' /etc/rc.local

此时，由于我们没有开启DHCP功能，因此只能设置静态IP地址。客户机设置如下：
eth0:192.168.0.10 掩码：255.255.255.0 网关：192.168.0.1

ubuntu 17.04/Debian 10无法运行gparted，错误信息“Gtk-WARNING **: cannot open display: :0.0”,具体信息如下：

具体的解释以及解决方法如下：

If running Ubuntu 17.10/Debian 10 or newer, this issue can arise when an application has not been updated with full support for Wayland. As a workaround until the application is updated, you can run

$ xhost +SI:localuser:root

1	$ xhost +SI:localuser:root

which will allow the root user to display applications on your desktop.

为了保证每次启动脚本都可以自动执行，可以把上面的命令加入到.bashrc:

$ sed -i '$a\xhost +SI:localuser:root' ~/.bashrc

1	$ sed -i '$a\xhost +SI:localuser:root' ~/.bashrc

Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)

参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)编译出来的Busybox是只有3MB大小的样子，这样编译出来的东西非常基础，功能有限。如果想要增加其他软件的时候，最少改动的情况下，一般都依赖GLIBC,而GLIBC完整编译出来的库接近50MB，而我们修复系统，是一个纯内存文件系统。直接采用GLIBC会非常浪费不多的内存空间。

因此在低内存的系统上采用uClibc，变成一个不错的选择。下面我们讲一下如何通过crosstool-ng-1.23.0构建一个我们需要的编译系统出来。

首先编译crosstool-ng-1.23.0源代码

$ sudo apt-get update
$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf
$ sudo apt-get -y install gperf
$ sudo apt-get -y install bison
$ sudo apt-get -y install flex
$ sudo apt-get -y install texinfo
$ sudo apt-get -y install help2man
$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf

$ sudo apt-get -y install gperf

$ sudo apt-get -y install bison

$ sudo apt-get -y install flex

$ sudo apt-get -y install texinfo

$ sudo apt-get -y install help2man

$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

如果下载crosstool-ng源代码存在问题，可以从本站下载一份代码拷贝。点击此处下载。

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

最终的.config文件，可以参考下面的配置信息，或者简单的拷贝这个文件到编译目录即可

NVIDIA TX2 (Ubuntu 16.04)上安装CUDA 8.0

使用如下方式安装：

$ cd ~ 

$ wget http://developer.download.nvidia.com/devzone/devcenter/mobile/jetpack_l4t/013/linux-x64/cuda-repo-l4t-8-0-local_8.0.84-1_arm64.deb

$ sudo dpkg -i cuda-repo-l4t-8-0-local_8.0.84-1_arm64.deb

$ sudo apt-get update

$ sudo apt-get install cuda-toolkit-8-0

$ cd ~

$ wget http://developer.download.nvidia.com/devzone/devcenter/mobile/jetpack_l4t/013/linux-x64/cuda-repo-l4t-8-0-local_8.0.84-1_arm64.deb

$ sudo dpkg -i cuda-repo-l4t-8-0-local_8.0.84-1_arm64.deb

$ sudo apt-get update

$ sudo apt-get install cuda-toolkit-8-0

至于如何获取最新的NVIDIA TX2上使用的CUDA 8.0版本的下载地址，请访问Jetson Download Center，下载目前最新的JetPack 3.1。执行之后在存储目录下的repository.json中找到最新的下载链接即可。当然也可以让JetPack 3.1自动下载完成最新的CUDA 8.0版本到指定目录。
