问题遇到的现象和发生背景
我使用vagrant启动了若干个virtualbox的虚拟机,有centos也有ubuntu,均有独立内网ip地址
问题相关代码,请勿粘贴截图

运行结果及报错内容
今天使用vagrant halt关闭了所有虚拟机并重启物理机后再次vagrant up打开各个虚拟机,结果就出问题了
centos能够正常ssh,ubuntu无法ssh
powershell
PS C:\Users\Administrator> ssh root@192.168.1.102
ssh: connect to host 192.168.1.102 port 22: Connection timed out
xshell
Host 'ubuntu.kamputer.online' resolved to 192.168.1.102.
Connecting to 192.168.1.102:22...
Could not connect to 'ubuntu.kamputer.online' (port 22): Connection failed.
Type `help' to learn how to use Xshell prompt.
但是从centos上能够ssh上ubuntu
试了多台服务器均是如此
我的解答思路和尝试过的方法
我试了xshell和powershell均无法连接
我想要达到的结果
通过xshell能够正常ssh登录ubuntu
