# How to Access and Control a Linux Virtual Machine Using PuTTY
In this step-by-step tutorial, you’ll learn how to access and fully control a Linux virtual machine using **PuTTY** from Windows 11. PuTTY is a popular SSH client that allows you to securely connect to Linux systems running in VirtualBox, VMware, or cloud environments and manage them using the command line.
This guide is perfect for beginners learning Linux, system administrators managing servers, DevOps engineers working with remote systems, and students practicing Linux commands in a virtual environment.
---
## What You Will Learn
By the end of this tutorial, you will be able to:
* Connect to a Linux VM using PuTTY
* Run Linux commands remotely from Windows 11
* Manage files, users, and services on your VM
* Control your Linux system using SSH securely
---
## Step 1: Install PuTTY on Windows 11
1. Download PuTTY from the official website
2. Install the Windows 64-bit version
3. Open PuTTY after installation
PuTTY is a lightweight SSH client used to connect to Linux systems securely over a network.
---
## Step 2: Find Your Linux VM IP Address
On your Linux virtual machine, open the terminal and run:
```bash id="x8v9k1"
ip a
```
Look for an IP like:
* `192.168.x.x`
* `10.0.x.x`
This is the address you will use in PuTTY.
---
## Step 3: Enable SSH on Linux VM
Install and start the SSH service:
For Ubuntu/Debian:
```bash id="sshsetup1"
sudo apt update
sudo apt install openssh-server -y
sudo systemctl enable ssh
sudo systemctl start ssh
```
Check status:
```bash id="sshstatus1"
sudo systemctl status ssh
```
---
## Step 4: Configure VirtualBox / VMware Network
To allow PuTTY access:
* **Bridged Adapter (Best Option):** VM gets same network as host
* **NAT + Port Forwarding:** Forward port 22 to VM
* **Host-Only:** Works only between host and VM
👉 For beginners, Bridged Adapter is the easiest and most reliable.
---
## Step 5: Connect Using PuTTY
1. Open PuTTY
2. Enter Linux VM IP in **Host Name**
3. Set Port: `22`
4. Select **SSH**
5. Click **Open**
---
## Step 6: Login to Your Linux VM
A terminal window will appear:
* Enter your Linux username
* Enter password (hidden while typing)
If correct, you are now connected to your Linux VM.
---
## Step 7: Control Your Linux VM Using PuTTY
Once connected, you can fully manage your Linux system:
### System Control Commands
```bash id="syscmd1"
sudo reboot
sudo shutdown now
```
### File Management
```bash id="filecmd1"
ls
cd /home
mkdir test
nano file.txt
```
### System Updates
```bash id="update1"
sudo apt update && sudo apt upgrade -y
```
### Process Management
```bash id="proc1"
top
ps aux
```
---
## Step 8: Improve Security with SSH Keys (Optional)
Instead of passwords, you can use SSH keys:
* Generate key using PuTTYgen
* Add public key to `~/.ssh/authorized_keys`
* Login without password
This is widely used in production servers.
---
## Common Problems & Fixes
**Connection timed out**
* Check VM IP address
* Ensure SSH service is running
* Use Bridged networking
**Permission denied**
* Wrong username/password
* SSH key mismatch
**Port 22 not working**
```bash id="firewall1"
sudo ufw allow ssh
```
---
## Final Thoughts
Using PuTTY to access and control a Linux virtual machine gives you real-world experience in system administration and server management. Once connected, your VM behaves like a remote Linux server that you can fully control from Windows 11.
