=> Practical Guide to Secure File Transfers

Access Credentials: Prepare the server's address, 
SSH port (in this example, we're using port 5031), and a user account with 
required permissions.


Part 1: Server-to-Local File Transfer
Step 1: Connect to the Server
Initiate an SSH connection to your remote server:

ssh -p 5031 student@xxxx.eastus.cloudapp.azure.com
Step 2: Create a Test File on the Server
Once connected, create a sample file to use for the transfer:

echo "Hello from the cloud!" > message.txt
To verify the file's content, use:

cat message.txt
Disconnect from the server after this step.

Step 3: Securely Transfer the File to the Local Machine
On your local machine, run:

scp -P 5031 student@xxxx.eastus.cloudapp.azure.com:message.txt /local/directory/path
Note: The -P flag specifies the port number used for the connection, 
essential when the remote server uses a port other than the default SSH port. 
The colon (:) is required to denote the path to the file or directory on the remote server.

Part 2: Local-to-Server File Transfer

Step 1: Update the File Locally
Edit the received file to include additional text:
echo "Acknowledged from the local machine." >> /local/directory/path/message.txt


Step 2: Transfer the Updated File Back to the Server

Use SCP to send the modified file back to the remote server:
scp -P 5031 /local/directory/path/message.txt student@xxxx.eastus.cloudapp.azure.com:/remote/directory/path


Part 3: Verification
Step 1: SSH into the Remote Server
Reconnect to the server using SSH:

ssh -p 5031 student@xxxx.eastus.cloudapp.azure.com


Step 2: Verify the File Content
Check the content of the transferred file:

cat /remote/directory/path/message.txt
You should see the updated text in the file, confirming a successful transfer.
