1. The first step is to find a new computer or an old computer with a low-level hard disk format, and install the Linux operating system Ubuntu when the network is disconnected (the following figure is an example of installing Ubuntu with a U disk):
the second step is to install the electrum bitcoin wallet< After installing the Ubuntu Linux operating system, install the electrum bitcoin wallet offline (I prefer electrum,
you can also use other light wallets such as multibit)
the third step is to generate a new cold wallet address
after installing, open electrum and create a new wallet, Follow the steps in Figure 4 to figure 8 to generate a new cold wallet address. By default, electrum creates five new addresses at a time,
note figure 8, and type "listaddress() & quot; The system will list the newly created five bitcoin addresses, and then use the getpubkeys command, or get the public key from the menu master public
key (public key and address are not the same concept). Please the public key and save it in a text file. Figure 9 shows the private keys of these five new addresses,
here is just for you to explain. For comparison with Figure 12, the five private keys are in the wallet of the never touch Linux operating system,
you should not do figure 9 in actual operation. And don't tell anyone else about your private key.

if you want to install a wallet, don't you read the readme file, which is provided by general software to explain what the software is used for, how to install it, and what operating environment it needs
if there is no readme file and there is only one binary file, treat it as an executable file and give permission first:
root@somepalce# > Chmod + X ABC
then execute: SH ABC
you just type & gt; The last string will do. The first one just reminds you to use the root permission.

1.下载安装包：ethtool-3.15.tar.gz，将其放入自己的路径下，解压：tarzxvfethtool-3.15.tar.gz
2.编译安装：
cdethtool-3.15
sudo./configure
sudomake
sudomakeinstall
3.ethtool-sethX[speed10|100|1000]//设置网口速率10/100/1000M

5. The minimum requirements of Windows 7 hard disk are as follows:
16GB for 32-bit system; The 64 bit system is 20GB
specific configuration requirements, Description:
1. CPU: 1 GHz 32-bit or 64 bit processor
2. Memory: 1 GB (based on 32 bits) or 2 GB (based on 64 bits)
3. Hard disk: 16 GB of available hard disk space (based on 32 bits) or 20 GB of available hard disk space (based on 64 bits)
4. Display: DirectX 9 graphics device with WDDM 1.0 or higher driver

6. sudo ./configure
sudo make
sudo make install

sudo make install
7. Double click the downloaded EXE file to install. In the second step, select the installation address, and also select a directory other than disk C, such as D: &# 92; Program Files\ Litecoin\ Then click Next until the installation is finished, a shortcut will be automatically created on the desktop, as shown in the figure below
right click the desktop litecoin shortcut and select properties. You can see that the target is: & quot; D:\ Program Files\ Litecoin\ litecoin-qt.exe", Add a space after exe, and then - dataDir = g: \ Litecoin
I am & quot; D:\ Program Files\ Litecoin\ litecoin-qt.exe" - datadir=G:\ Litecoin
where G: &# 92; Litecoin can be assigned to the corresponding place according to the situation of its own hard disk, - dataDir must be separated by a space in front of it, and the system with a space in the front path will automatically add double quotation marks, - dataDir should be behind the double quotation marks.

8. There is a space in the middle: ifconfig-a network card name is not necessarily eth0, it may be other name. If you don't see the network card, it means that the system doesn't recognize it, and you need to install another driver
9. You want a network card device, right
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP
use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
