Go Ethereum

1. The next morning, Linda got u

2. Eth1 seems to be a naming method under Linux, which is not defined in Mac OS. The front row of children's shoes said, first check whether there is eth1 equipment.

3.

Hello, many examples are that eth. Getcompilers() returns solidity or configures Solc

and then reports error: the method eth_ Getcompilers does not exist / is not available error

because this method has been removed after 1.6, and it is not advisable to use lower version geth

solution:

< UL >

start an Ethereum node (such as geth private chain or testrpc)

compile smart contracts with Solc

the compiled contract is deployed to the network

the JavaScript API provided by eb3.js is used to call the contract Depending on the type of call, it may consume Ethernet currency.)

< / UL >

hope to help you

5. Do you use the network card managed by network manager? Look at this error report. I guess it has something to do with network manager.

6. Solution: 1. Right click "my computer" in the system and select "properties"
in the system properties window, select the Advanced tab and press the environment variable button; Step 2: add the SecureCRT. V5.5.2 installation path to the path value of the system variable in the environment variable setting window, such as "directory"; C:\ Program Files\ S

7. I got it! do like this:
mininet> py h1.setIP('10.0.0.3/24')
mininet> py h2.setIP('10.0.0.4/24')
mininet> h1 ping h2

Hi everyone,

When I change host's IP, other hosts cannot ping through it, but it can ping other host.
And I find that, when typing in mp command, it shows that the IP is not changed.
That's why? How can I really change the ip of virtual host?
