SFTP Configuration Guide

This guide will walk you through the process of setting up SFTP on your server. SFTP (Secure File Transfer Protocol) is a secure way to transfer files over a network.

Prerequisites

A server with SSH access
SFTP server software installed (e.g., OpenSSH, vsftpd)

Steps

Install SFTP Server Software

Depending on your operating system, the installation process will vary. Here's an example for installing OpenSSH on Ubuntu:
```
sudo apt update
sudo apt install openssh-server
```
Configure SSH

Edit the SSH configuration file to allow SFTP connections:
```
sudo nano /etc/ssh/sshd_config
```
Look for the following lines and ensure they are uncommented and set to yes:
```
PermitRootLogin no
PermitSFTPLogin yes
```
Save and close the file.
Create a User

Create a new user for SFTP access:
```
sudo adduser sftpuser
```
Set a password for the user.
Set Permissions

Set the appropriate permissions for the user's home directory:
```
sudo chown -R sftpuser:sftpuser /home/sftpuser
```
Start the SFTP Service

Restart the SSH service to apply the changes:
```
sudo systemctl restart ssh
```
Connect to SFTP

Use an SFTP client (e.g., FileZilla, WinSCP) to connect to your server. Enter the server's IP address, username, and password.

Troubleshooting

If you encounter any issues, check the following:

Ensure the SFTP server software is running.
Verify the SSH configuration file settings.
Check the user's permissions and home directory.
