How to retreive code in an instance?

Question

We have an instance on EC2, nd we would like to retreive the code in this instance for adjustments. And we want to download the code in this instance to our laptop. 1) Could you tell me how I can managet to get this done? 2) Also, I have encountered 'Error establishing SSH connection to your instance'. How can I solve this?

Hello

By following these steps, you should be able to retrieve your code from the EC2 instance and resolve any SSH connection issues you encounter.

**Solve SSH Connection Issues**
If you encounter "Error establishing SSH connection to your instance", follow these troubleshooting steps:

**Verify Key Pair Permissions**:

> Ensure the private key file has the correct permissions:

sh
Copy code
chmod 400 /path/to/your-key.pem

**Check Security Group Rules:**
Confirm that the security group associated with your instance allows SSH access from your IP.

**Public IP or DNS**:
Make sure you're using the correct public IP address or public DNS name of your instance.

**Network ACLs:**
Verify that the Network ACLs associated with your VPC allow inbound SSH traffic.

**Retrieve and Download Code**
Once connected via SSH, you can use scp (secure copy) to transfer files from your EC2 instance to your local machine.

**On Your Local Machine:**
Open a terminal and use the scp command to copy files from the EC2 instance to your laptop:

> scp -i /path/to/your-key.pem ec2-user@:/path/to/remote/file /local/destination/path

**For example, to copy a directory (use the -r option for recursive copy):**

> scp -i /path/to/your-key.pem -r ec2-user@:/path/to/remote/directory /local/destination/directory
