Terminal in Linux on remote laptop keeps hanging while I am sshed into EC2 Instance

Hello.

Does the same phenomenon occur with connection methods other than SSH?
For example, will it become impossible to operate even if I connect with Systems Manager Session Manager?

By the way, when using VSCode's RemoteSSH, a phenomenon may occur that consumes a large amount of memory.

Hi

There can be a few reasons why your terminal hangs while SSH into your EC2 instance.

Check the SSH Connection:

Verbose Logging: Use the ssh -vv flag to get more detailed information about the connection process. This might reveal errors during the initial handshake or key exchange.

Security Group Rules: Verify that your security group allows SSH access on port 22 from your local machine's IP address. You can check and modify security groups in the AWS Management Console.

AWS Documentation: The AWS documentation has detailed information on troubleshooting SSH connections to EC2 instances https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html.

Stack Overflow: Stack Overflow is a great resource for troubleshooting Linux and AWS related issues. Search for "SSH hangs EC2" to find solutions from other users https://stackoverflow.com/questions/50925384/ssh-hangs-when-attempting-to-connect-to-amazon-aws-ec2-instance.
