在家时,我可以使用 ssh 连接到另一台计算机
ssh [email protected] -p 2222
如果外出并尝试连接到家里的电脑
me@alpha:~$ ssh [email protected] -p 2222
ssh: Could not resolve hostname assistant.remote: Name or service not known
me@alpha:~$ ssh assistant@beta -p 2222
ssh: Could not resolve hostname assistant: Temporary failure in name resolution
如何完成?
