Ethereum public IP

1. Set up the DHCP server and distribute it from eht1

2. How many account addresses can an Ethereum node have at most
A: generally, there is only one account address, otherwise there will be an error! blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!

3. Where are you going? Wallet or exchange
transfer eth, as long as there is an address, you can transfer it out
mnemonic words are things that you can help to find when you forget your key, not related to money collection.

4. Compared with bitcoin and Ethereum, IPFs miner needs to contribute "hard disk" and "bandwidth". It doesn't need to invest a lot of money in the initial stage to buy expensive hardware to provide computing power, and it doesn't need to spend a large amount of electricity. Filecoin (IPFs) also provides 70% incentive as mining return, which is very sincere in proportion. The hummingbird H1 miner that focuses on interstellar bit is recommended.

5. 检查修改 /etc/sysconfig/network-scripts/ifcfg-eth0
添加：
IPADDR=X.X.X.X
NETMASK=255.255.255.0
GETEWAY=X.X.X.1
试一试，应该是网络没有设置

6. There is an eth0 under Linux, which is only the IP address of the first physical network card

7. First, create a VLAN in the system view, such as VLAN 10
then, enter the ETH trunk interface you have established, change the interface mode to trunk, and allow vlan10 to pass:
port link type trunk,
port trunk allow pass vlan10,
finally, configure vlan10 with the interface IP you want:
interface vlanif10,
IP address 192.168.1.124
this IP is the interface IP of eth trunk.

8. First, ifconfig to see if there is eth0. If not, what is the error prompt? If ifconfig is set, it will automatically up. You don't need to be in ifup. If ifup doesn't work, you can try ifconfig
eth0
up. I don't know how to ask
