無法通過ubuntu中的配置文件將ssh連接到ec2。 權限被拒絕（公鑰，gssapi-keyex，gssapi-with-mic）

Question

無法通過Ubuntu連接到SSH。 但它在MAC上工作正常。

我的配置文件

Host testserver
User ubuntu
IdentityFile '/home/kavin/.ssh/AnotherKey.pem' 
HostName ec2-54-201-xxx-xxx.us-west-2.compute.amazonaws.com

通過SSH連接

$ ssh testserver

這與我為Mac和Ubuntu所做的一樣。 它可以在Mac上完美運行，但是在Ubuntu中會引發錯誤， Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

現在我嘗試了另一種方式ssh -i '/home/kavin/.ssh/AnotherKey.pem' ec2-user@54.201.xxx.xxx

在Mac和Ubuntu上都可以正常工作。

你能告訴我我哪里出問題了嗎

這些是$ ssh testserver -v的日志

Answer 1

正如你所說，

ssh -i '/home/kavin/.ssh/AnotherKey.pem' ec2-user@54.201.xxx.xxx

來自ubuntu m / c的工作原理和ssh testserver失敗。 我建議從配置文件中注釋其他行，然后繼續

IdentityFile /home/kavin/.ssh/AnotherKey.pem 

確保刪除引號，並且路徑應直接可用於鍵。

Answer 2

轉到終端：

1. gksu nautilus（輸入您的root密碼）
2. 瀏覽到/ etc / ssh /
3. 將您的“密鑰”復制到/ etc / ssh /
4. 打開ssh_config

5. 復制粘貼：

   主機測試服務器

   主機名ec2-54-201-xxx-xxx.us-west-2.compute.amazonaws.com

   用戶ubuntu

   IdentityFile /etc/ssh/AnotherKey.pem

6. 保存-退出

7. 打開新終端

8. 須藤-i

9. 輸入密碼

10. cd / etc / ssh

11. chmod 400'您的鑰匙'

12. SSH測試服務器

-確保您的22端口是開放的
