Ubuntu 无法复制rsa密钥

当我尝试运行

ssh copy id

时，会出现以下错误：

abcd@hostOnDigitalOcean:~/.ssh$ ssh-copy-id xyz@targetHostIP
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/abcd/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/usr/bin/ssh-copy-id: ERROR: ssh: connect to host targetHostIP port 22: Connection timed out

我尝试了

ssh复制id-Ixyz@targetHostIP

---

同样的错误。

您可以手动复制它

cat ~/.ssh/id_rsa.pub

ssh

to

targetHostIP

---

粘贴在

~/.ssh/authorized_keys

的末尾。您可以手动复制它

cat ~/.ssh/id_rsa.pub

ssh

to

targetHostIP

---

粘贴在

~/.ssh/authorized_keys的末尾
