Part 1 - Prerequisites for Connecting to EC2 Using Filezilla

We need to make sure we have some things ready to connect to our Amazon EC2 instance using Filezilla and SFTP. Here is what we need:

AWS Account: We must have an active AWS account to create and manage EC2 instances.
EC2 Instance: We should launch an EC2 instance on AWS. We can pick an Amazon Linux, Ubuntu, or another supported AMI.
Key Pair: We need to create a key pair when we launch the instance. We should download the private key (like my-key.pem) and keep it safe.
Filezilla Client: We have to download and install Filezilla on our computer. We should check that it is the latest version.
Public IP Address: We must get the public IP address or public DNS of our EC2 instance from the AWS Management Console.
SFTP Access: We need to make sure port 22 is open in our EC2 instance’s security group settings. This allows SFTP connections. We can check Configuring Security Groups for SFTP Access to set this up right.
File Permissions: We need to change the permissions of our private key file to be read-only. We can do this with the command:
```
chmod 400 my-key.pem
```

After we finish these steps, we will be ready to set up Filezilla to connect to our EC2 instance using SFTP.

Part 2 - Configuring Security Groups for SFTP Access

To connect to our Amazon EC2 instance using FileZilla and SFTP, we need to set up the security groups for our EC2 instance. This helps to make sure the right ports are open for SFTP access.

Log in to the AWS Management Console.
Go to EC2 Dashboard:
- In the navigation pane, click on Instances.
- Select the instance we want to change.
Change the Security Group:
- In the Description tab, find the Security Groups section.
- Click on the security group link for our instance.
Add Inbound Rule for SFTP:
- Click on the Inbound rules tab and then click Edit inbound rules.
- Click on Add rule.
- Set up the rule like this:
  - Type: Custom TCP
  - Protocol: TCP
  - Port Range: 22 (this is default for SFTP)
  - Source: Choose My IP to allow only our IP, or Anywhere for more access (not good for production).
- Click Save rules.
Check Security Group Settings:
- Make sure the rule we added is listed and set up correctly. We should see something like:
```
Type      Protocol    Port Range    Source
Custom TCP  TCP       22            Our IP or 0.0.0.0/0
```

By doing these steps, we will have set up the security group for SFTP access to our Amazon EC2 instance. This setup is very important to make sure that our FileZilla client can connect safely to the EC2 file directory.

Part 4 - Setting Up Your EC2 Instance for SFTP

We will set up your Amazon EC2 instance for SFTP. Let’s follow these steps:

Launch EC2 Instance:
- First, go to the AWS Management Console.
- We select EC2 and click on “Launch Instance”.
- Choose an Amazon Machine Image (AMI) and the instance type. Make sure to pick an instance type that is right for you like t2.micro for free tier.
- We need to configure instance settings and add storage if needed.
Create and Configure Key Pair:
- We can create a new key pair or use one we already have.
- Download the .pem file to your local machine. This file is very important to connect via SSH and SFTP.
Configure Security Group:
- In the “Configure Security Group” step, we create a new security group or pick an existing one.
- We add an inbound rule:
  - Type: Custom TCP
  - Protocol: TCP
  - Port Range: 22 (for SFTP)
  - Source: Your IP (use 0.0.0.0/0 for public access, but this is not good for security).
Connect to EC2 Instance via SSH:
- We use this command to connect to our instance:
```
ssh -i /path/to/your-key.pem ec2-user@your-ec2-public-dns
```
- Replace /path/to/your-key.pem with the path to your key file and your-ec2-public-dns with your instance’s public DNS.
Install and Configure SFTP:
- After we connect, we check that openssh-server is installed. It is usually already there.
- We create a new user for SFTP access:
```
sudo adduser sftpuser
sudo passwd sftpuser
```
- Then, we add the user to the sftp group:
```
sudo usermod -aG sftp sftpuser
```

Configure SSH for SFTP:

We edit the SSH configuration file:
```
sudo nano /etc/ssh/sshd_config
```

We add these lines at the end of the file:

Match User sftpuser
    ChrootDirectory /home/sftpuser
    ForceCommand internal-sftp
    AllowTcpForwarding no

Set Permissions:

We set the directory permissions:

sudo chown root:root /home/sftpuser
sudo chmod 755 /home/sftpuser
mkdir /home/sftpuser/files
sudo chown sftpuser:sftpuser /home/sftpuser/files

Restart SSH Service:
- We restart the SSH service to apply the changes:
```
sudo systemctl restart sshd
```

Now, your EC2 instance is ready for SFTP. You can connect using FileZilla by giving the EC2 public DNS, the SFTP username, and the key file. If you have problems, you can check this link for common SFTP connection issues.

Part 5 - Connecting to EC2 Instance with Filezilla

To connect to your Amazon EC2 instance using FileZilla and SFTP, we can follow these steps:

Open FileZilla:
We start by launching the FileZilla application on our computer.

Frequently Asked Questions

1. How do I fix the “Permission Denied” error when connecting to my EC2 instance using Filezilla?

If we see a “Permission Denied” error when we try to connect to our Amazon EC2 instance with Filezilla, it usually means there is a problem with our private key permissions or the SSH settings of our EC2 instance. We need to check that our private key file has the right permissions. It should be read-only for the owner. Also, we must use the correct username for our instance type. For more help, we can check our guide on how to fix permission denied.

2. What are the security group settings required for SFTP access to EC2?

To let SFTP access our Amazon EC2 instance, we have to set up our security group to allow incoming traffic on port 22 for SSH. This will let Filezilla connect in a secure way using the SFTP protocol. We should also limit access to specific IP addresses for better security. For more details on setting up security groups, we can read our article on how to open port 80 on EC2.

3. Can I use other SFTP clients besides Filezilla to connect to my EC2 instance?

Yes, we can use other SFTP clients like WinSCP, Cyberduck, and Transmit to connect to our EC2 instance. Filezilla is popular but not the only option. Each client has its own setup steps, but the basic needs are the same. We should have our EC2 instance’s public IP, username, and private key file ready for connecting.

4. How do I change the key pair for my EC2 instance if I lost access?

If we want to change the key pair for our Amazon EC2 instance but lost access, we can create a new key pair and attach it to the instance. This usually means stopping the instance, detaching the root volume, attaching it to another instance, changing the ~/.ssh/authorized_keys file, and then reattaching the volume. For more details, we can read about how to change the key pair for EC2.

5. What should I do if my SFTP connection to EC2 times out?

If our SFTP connection to the Amazon EC2 instance times out, there might be a problem with security group settings, network issues, or the instance could be stopped. First, we should check that our security group lets incoming traffic on port 22. We also need to see if our instance is running on the AWS Management Console. If the problem does not go away, we can try to fix our local network settings or use another network. For more tips on troubleshooting, we can see our article on how to fix AWS Lambda API issues.
