1核心 2g 1M 带宽 华为云 跑iperf

1核心 2g 1M 带宽 华为云

• 华为云最近特价
• 购买了一台最低配的一年79

控制台

• 我的ecs列表
• 18.04.3
• 密码可以控制台重置
• 可以远程web登录
• 只有40g内存

弹性公网ip

• 可以用这个ip，用户名root + 自己密码登录
• 我的在华南

可用空间35G

-能干点啥呢？

跑个iperf试试

• 2019最新的
• 安装

sudo apt remove iperf3 libiperf0
sudo apt install libsctp1
wget https://iperf.fr/download/ubuntu/libiperf0_3.7-3_amd64.deb
wget https://iperf.fr/download/ubuntu/iperf3_3.7-3_amd64.deb
sudo dpkg -i libiperf0_3.7-3_amd64.deb iperf3_3.7-3_amd64.deb
rm libiperf0_3.7-3_amd64.deb iperf3_3.7-3_amd64.deb

安全组

• 没看懂，安全组规则
• 默认规则改为full acess 就可以随便用了
• 默认规则

iperf

• hwy 服务端打印的

:/usr/local# iperf3 -s -i 1 -p 12345
-----------------------------------------------------------

看起来这个是我家电信的出口ip  和 实际通信的出口端口50888
Accepted connection from 58.248.229.888 port 50888
本地ip 监听12345 端口，然后链接到了我mac机器的64231端口？？？？

jitter开始很大，后来越来越小，只有8毫秒，带宽能达到6 Mb/s ，我的hwy机器是买的1Mb/s啊？？？
