无法通过ubuntu中的配置文件将ssh连接到ec2。拒绝许可(公开密钥，gssapi-keyex，gssapi-with-mic)

Question

无法通过Ubuntu连接到SSH。但在MAC上效果很好。

我的Config文件

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

通过SSH连接

$ ssh testserver

这和我对Mac和Ubuntu做的一样。它在Mac中运行得很好，但是在Ubuntu中抛出了一个错误Permission denied (publickey,gssapi-keyex,gssapi-with-mic).。

现在我尝试了另一种方法-- ssh -i '/home/kavin/.ssh/AnotherKey.pem' ec2-user@54.201.xxx.xxx

这在Mac和Ubuntu中都很好。

你能告诉我哪里出了问题吗？

这些是$ -v的日志

Answer 1

就像你说的

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

从ubuntu /c工作到ssh testserver失败。我建议对配置文件中的其他行进行注释，只需保留

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

确保，您删除引号和路径应该直接可用的键。

Answer 2

Goto终点站：

1. gksu nautilus (输入您的根密码)
2. 浏览至/etc/ssh/
3. 在/etc/ssh/复制您的“密钥”
4. 开放ssh_config
5. 复制粘贴： 主机测试服务器 HostName ec2-54-201-xxx-xxx.us-west-2.compute.amazonaws.com 用户ubuntu IdentityFile /etc/ssh/AnotherKey.pem
6. 储蓄-出口
7. 开放新终端
8. 数独-i
9. 输入密码
10. cd /etc/ssh
11. chmod 400“你的钥匙”
12. ssh测试服务器
