篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了记一次 Vultr配置相关的知识，希望对你有一定的参考价值。

这里不想排版，因为心情复杂。

第一次搞这个VPS，真的是很气人，由于中英文的关系我一开始就误操作了，让VPS一直挂载着Ubuntu18.10,所以系统一直是在光盘的引导界面，这个问题知道我注册后的四个小时才知道！

 

还有，就是它有一个活动，充十块充五十块，这个下面有一个大大的Remove,千万别去点到，不然你就没有了，郁闷。

 

去掉光盘挂载以后，就能进系统并且SSH登陆配置了。

//SSH登陆 (这里使用Xshell6) 百度即可
//安装宝塔：
//SSH终端输入一句话就行了，复制下面然后粘贴回车。
yum install –y wget && wget -O install.sh http://download.bt.cn/install/install.sh && sh install.sh

 

问题解析： 为什么下载了SSH登陆客户端却显示网络中断？

这个问题对我来说没什么卵用，因为我根本不是出的这个错误，不过还是分享一下。

I‘m trying to connect to a distant server from a Mac device. When I type the ssh command:

ssh [email protected]

I receive this error:

Connection closed by xx.xxx.xxx.xx port 22

I was told to restart ssh this way : service sshd restart but when I execute it, I‘m told that service is not found.

I‘m a newbie and I know that I‘m missing something. Your help would so welcome.

Regards!

    this may be better for unix SE or super user SE - that aside. I get this sometimes when the server you‘re connecting to is on a different port from 22. Also that restart command should be run on the server - not your machine – treyBake Nov 1 ‘18 at 12:19

    @ThisGuyHasTwoThumbs How can I run it on the server while I can‘t connect to it? – zakaria mouqcit Nov 1 ‘18 at 13:28

    is it an external server you have no control over? – treyBake Nov 1 ‘18 at 13:29

    Yes it‘s an external server that I can only access to it via terminal or filezilla. While I can‘t connect I can do nothing. – zakaria mouqcit Nov 1 ‘18 at 13:30

    is it a hosting company-controlled server? – treyBake Nov 1 ‘18 at 13:35

  1. Check the server computer is opened 20 port

Windows - [run -> cmd -> type this string]

       netstat -an

Linux - [in terminal]

      netstat -nap

type this string in your server computer what you have you can check what port is opened




  1. let server computer allow access port 22

Windows

goto Firewall -> advanced settings -> Inbound rules -> new rules -> add port tcp/22

Linux

iptables -I INPUT 1 -p tcp --dport 22-j ACCEPT 

iptables -I OUTPUT 1 -p tcp --dport 22-j ACCEPT

you have to do by root
