Linux and Ethereum always fail to connect

1.

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 />

2. Just set IP to get it automatically
VI / etc / sysconfig / network scripts / ifcfg-eth0
change bootproto = static to bootproto = DHCP

3. Select network
or some versions of setup and use netconfig to set
or VI / etc / sysconfig / network script / ifcfg-eth0
to
device = eth0
onboot = yes
bootproto = DHCP

Restart network service


generally, if it is set to DHCP, use dhclient eth0

4. Let me tell you the steps. First of all, make sure your hardware connection is OK
1. Make sure the eth0 status is up, sudo ifconfig eth0 up
2. Configure IP, sudo ifconfig eth0 x.x.x
3. Add default gw x.x.x (your route)
4. Set DNS, edit / etc / resolv.conf file, and change the content to nameserver x.x.x.x
5 Restart the network instead of restarting the machine. Sudo / etc / init.d/networking restart

if you are in FC environment, you may be prompted that ifconfig cannot be found, just change to / SBIN / ifconfig

5. /Etc / sysconfig / network scripts / ifcfg-eth0

modify this file
to
device = eth0 device name
bootproto = none do not use DHCP to write none or static
hwaddr = 00:1e: 67:6e: e7:33 MAC address is OK (do not each network) Card MAC address is different)
onboot = yes boot
netmask = 255.255.255.0 subnet mask
IPADDR = 1.1.1.1 IP address
gateway = 1.1.1.1 gateway
type = Ethernet type can be written without writing

6. What do you want to ask? Your CentOS is your virtual machine installed on windows. What do you want to ask when you post these two pictures?

7. Link detected: no means your network cable is not connected well!

8. What ssh server does XP run
you can run the netstat - an command to see if port 22 is monitored
if you can see the monitoring of port 22, it means that the SSH service is started, then check whether there are firewall settings and account restrictions

9. Change eth0 to manual setting, and then
set your virtual machine connection mode to bridge mode, and then try again
if not, see if your network card driver is not loaded

10. Click the "start" button in the lower left corner of the screen and select "printer and fax" from the pop-up menu list

in the "printers and faxes" window, click the "Add Printer" command on the left

the Add Printer Wizard dialog box will pop up and click next to continue< In general, we choose the first option, and we also choose more network printers.

linux is a set of UNIX like operating system that is free to use and spread freely. It is a multi-user, multi task, multi thread and multi CPU operating system based on POSIX and UNIX. It can run the main UNIX tools, applications and network protocols

it supports 32-bit and 64 bit hardware. Linux is a stable multi-user network operating system, which inherits the design idea of UNIX with network as the core

the Linux operating system was born on October 5, 1991 (the first time it was officially released). There are many different versions of Linux, but they all use the Linux kernel

linux can be installed in a variety of computer hardware devices, such as mobile phones, tablets, routers, video game console, desktop computers, mainframes and supercomputers

strictly speaking, the word Linux only refers to the Linux kernel, but in fact, people are used to using Linux to describe the whole Linux kernel, and use GNU engineering tools and database operating system.
