SSH key authentication not working in Tera Term
问题
我正在创建一个CDK部署，以自动化服务器的部署。到目前为止，这是我的代码：
// 创建SSH密钥对
let keyPair = new ec2.CfnKeyPair(this, "PublicEC2Key", {
keyName: "public-ec2-key",
tags: [new cdk.Tag("Name", `public-ec2-key`)],
});
// 创建安全组
const publicEC2SG = new ec2.SecurityGroup(this, `publicEC2SG`, {
vpc: vpc,
allowAllOutbound: true,
description: `Public CLC instance Security Group`,
securityGroupName: `clc-public-ec2-sg`,
});
publicEC2SG.addIngressRule(
ec2.Peer.anyIpv4(),
ec2.Port.tcp(22),
"SSH from anywhere"
);
// 在公共子网中启动EC2实例（以便通过SSH访问）
let ec2_public = new ec2.Instance(this, "PublicEC2", {
vpc: vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PUBLIC,
},
instanceType: ec2.InstanceType.of(
ec2.InstanceClass.T2,
ec2.InstanceSize.MICRO
),
role: roleEC2,
machineImage: ec2.MachineImage.latestAmazonLinux2023(),
instanceName: `clc-public-ec2`,
keyName: keyPair.keyName,
securityGroup: publicEC2SG,
});
在正确部署VPC和实例后，我可以在控制台上看到实例和密钥对。然后我转到Parameter store，从那里复制密钥并创建一个名为public-ec2-key.pem的新文件，在其中粘贴证书代码（从-----BEGIN RSA PRIVATE KEY-----到-----END RSA PRIVATE KEY-----包括在内）。
我更改文件的权限为：
chmod 400 public-ec2-key.pem
最后，我尝试使用Tera Term连接到EC2实例，并使用创建的.pem文件，但它返回身份验证错误。
我可以通过SSH访问实例，但无法正确验证。我是否漏掉了一步？
谢谢，祝一切顺利！
更新：当我尝试直接使用Linux终端的ssh命令连接时，它可以正常工作：
ssh -i "public-ec2-key.pem" ec2-user@ec2-ip-address.compute-1.amazonaws.com
我需要在我的TeraTerm中配置什么吗？
英文:
I'm creating a CDK deployment to automate the deployment of a server. This is my code so far:
let keyPair = new ec2.CfnKeyPair(this, "PublicEC2Key", {
keyName: "public-ec2-key",
tags: [new cdk.Tag("Name", `public-ec2-key`)],
});
// Create security group
const publicEC2SG = new ec2.SecurityGroup(this, `publicEC2SG`, {
vpc: vpc,
allowAllOutbound: true,
description: `Public CLC instance Security Group`,
securityGroupName: `clc-public-ec2-sg`,
});
publicEC2SG.addIngressRule(
ec2.Peer.anyIpv4(),
ec2.Port.tcp(22),
"SSH from anywhere"
);
// Launch EC2 instance in the public subnet (to be able to access it via SSH)
let ec2_public = new ec2.Instance(this, "PublicEC2", {
vpc: vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PUBLIC,
},
instanceType: ec2.InstanceType.of(
ec2.InstanceClass.T2,
ec2.InstanceSize.MICRO
),
role: roleEC2,
machineImage: ec2.MachineImage.latestAmazonLinux2023(),
instanceName: `clc-public-ec2`,
keyName: keyPair.keyName,
securityGroup: publicEC2SG,
});
After correctly deploying the VPC and the instance I can see both the instance in the console as well as the key pair. I then go to the
Parameter store from where I copy the key and create a new file named public-ec2-key.pem where I paste the certificate code (from -----BEGIN RSA PRIVATE KEY----- to -----END RSA PRIVATE KEY----- included).
I change the permissions of the file to:
chmod 400 public-ec2-key.pem
Finally I try to connect to the EC2 instance using Tera Term and the .pem file created but it returns an authentication error.
The instance is accesible via SSH, but I cannot authenticate correctly. I'm I missing a step?
Thank you and best regards!
UPDATE: When I try connecting through ssh command using the linux terminal directly it works:
ssh -i "public-ec2-key.pem" ec2-user@ec2-ip-address.compute-1.amazonaws.com
It's there anything I need to configure in my TeraTerm?

我怀疑你正在尝试使用 rsa-sha2-256 或 rsa-sha2-512。这不受当前版本的 Tera Term 支持。请尝试 Tera Term 5 RC 5.0 beta1，它支持这些功能。

I suspect you are trying to use rsa-sha2-256 or rsa-sha2-512. This isn't supported by the current version of Tera Term. Try Tera Term 5 RC 5.0 beta1, which does.
