got以太坊
① GNS3不能關聯GNS3VM出現如圖錯誤
解決方法: 1、在系統中「我的電腦」上點滑鼠右鍵選擇「屬性」。
在系統屬性窗口選擇「高級」標簽並按「環境變數」按鈕;第二步:將環境變數設置窗口中的系統變數里的Path值中在原有的值後面添加SecureCRT.v5.5.2安裝路徑,比如下目錄「;C:\Program Files\S。
② the method eth.getcompilers does not exist怎麼辦
你好,很多例子是eth.getCompilers()返回solidity 或者配置solc
然後會報Error: The method eth_getCompilers does not exist/is not available的錯誤
因為1.6以後已經移除了這個方法 使用低版本的geth也不可取
解決方法:
啟動一個以太坊節點 (例如geth私有鏈之類的或者testrpc)。
用solc編譯智能合約。
編譯好的合約部署到網路。
eb3.js提供的JavaScript API來調用合約。(根據調用的類型有可能會消耗以太幣。)
希望對你有幫助
③ python 環境下 socket.socket的get_ip_address("eth1")執行報錯,代碼如下:
eth1似乎是Linux下的命名方法,Mac OS不是這么定義的。前排童鞋說的,先查一下有沒有eth1這個設備。
④ 如何在Mininet中修改host的IP地址
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
PING 10.0.0.4(10.0.0.4)56(84) bytes of data.
64 bytes from10.0.0.4: icmp_req=1 ttl=64 time=2.38 ms

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?
