Ethereum basic command

1. Eth interface refers to the interface, is the most widely used LAN communication mode, but also a protocol. Ethernet interface is the port of network data connection
each version of Ethernet has a maximum cable length limit (that is, the length without amplification). Signals within this range can propagate normally, and signals beyond this range cannot propagate
in order to allow the construction of a larger network, repeaters can be used to connect multiple cables. Repeater is a physical layer device, which can receive, amplify and retransmit signals in two directions
extended data
several common Ethernet interface types
1. SC optical fiber interface
SC optical fiber interface has been applied in the era of 100base TX Ethernet, so it was called 100base FX at that time (F is the abbreviation of optical fiber). However, at that time, because the performance was not more prominent than twisted pair, but the cost was higher, so it was not popularized. Now the instry vigorously promotes gigabit network, and SC optical fiber interface is re valued
2. RJ-45 interface
this kind of interface is the most common network equipment interface, commonly known as "crystal head", and the professional term is RJ-45 connector, which belongs to the type of twisted pair Ethernet interface. RJ-45 plug can only be inserted along the fixed direction, and a plastic spring piece is set to be stuck with RJ-45 slot to prevent it from falling off
3. FDDI interface
FDDI has the highest transmission rate among the mature LAN technologies. It has the characteristics of timed token protocol, supports a variety of topologies, and its transmission medium is optical fiber. Fiber distributed data interface (FDDI) is a set of protocols developed by American National Organization for Standardization (ANSI) to transmit digital signals on optical cables

How to use the Linux system mining, to use the service of the HA Yu miner, only need two steps, you can mine on the Linux system

1. open the website, input the mobile phone number, select how many CPUs you want to use for mining, the default is to use 50% of the CPU for mining, click to generate your exclusive command and



in two steps, you can mine on Linux system, the money you dig only needs to go to the website of hayu miner, enter your mobile phone number to withdraw< br />

3. Use the direction key to move the cursor to the position you need to edit, and then input the characters directly, just like editing the txt file on your computer. Remember to call up: WQ!, Save and exit.

4. It should be Linux that adds routing paths< The routing path added by route add - net 10.26.96.0/28
GW 10.62.26.113 must pass through the network card selected by this gateway
dev eth2

5. No, based on eth.

7. Batch processing set IP address
I wonder if my friends have such experience. When I bring my notebook to work, because the work needs to be equipped with a fixed IP address, and my home automatically obtains the IP address, I have to set this IP address every day. Is there a simple and convenient way? In fact, we can do a batch process. Each time we want to set the IP address, we just need to run the batch process
first, set the IP address batch processing, save the following code in Notepad as a. Bat file, such as: static. Bat, double-click to run<
@ echo off
echo modify local IP address tool
echo is setting your IP address as a static address, please wait...
Netsh interface IP set address name = & quot; Local connection & quot; source=static addr=192.168.1.102 mask=255.255.255.0
netsh interface ip set address name=" Local connection & quot; source=static gateway=192.168.1.1 gwmetric=0
netsh interface ip set dns name=" Local connection & quot; source=static addr=41.211.224.7 register=primary
netsh interface ip add dns name=" Local connection & quot; addr=41.211.224.3
netsh interface ip set wins name=" Local connection & quot; Source = static addr = none
the related parameters in the above code are described as follows, It can be modified according to your actual situation:
addr = 192.168.1.102 -- IP address
mask = 255.255.255.0 -- subnet mask
gateway = 192.168.1.1 -- gateway
addr = 41.211.224.7 -- preferred DNS
addr = 41.211.224.3 -- standby DNS (if there is no standby DNS, please delete the whole line of code)
2 Set to automatically obtain the IP address, save the following code in Notepad as. Bat file, such as: DHCP. Bat, double-click to run
@ echo off
echo modify local IP address tool
echo is setting to automatically obtain IP address, please wait...
Netsh interface IP set address name = & quot; Local connection & quot; source=dhcp
netsh interface ip set dns name=" Local connection & quot; Source = DHCP
note: the "local link" in the above code is the system default name of the network link in your computer. If you have installed multiple network cards or changed the name of the local link, please change the corresponding local link name in the code to your current name.

8. ifconfig eth0:0 192.168.1.230 netmask 255.255.255.0

9. It has nothing to do with Jinshan drug bully. It should be that you, the computer manager, have bound the installation program of Jinshan drug bully
you can try to uninstall the computer manager and restart it.
