How to configure remote access on Linux

How to configure remote access on Linux

Overview:
In a Linux system, we can access and control the Linux host from other computers or devices by configuring remote access. This can greatly facilitate our remote operation and management. This article explains how to configure remote access on Linux and provides corresponding code examples.

1. SSH remote access
   SSH (Secure Shell) is a commonly used protocol to ensure communication security. We can remotely log in to the Linux host through SSH. The following are the steps to configure SSH remote access:
2. Install the OpenSSH server software:

sudo apt-get install openssh-server

2. Start the SSH service:

sudo service ssh start

3. Check the SSH service status:

sudo service ssh status

4. Remote login using SSH:

ssh username@remote_host_ip

2. VNC Remote Desktop Access
   VNC (Virtual Network Computing) Yes A protocol that enables remote access and control of computers through a graphical interface. Here are the steps to configure VNC remote desktop access:
3. Install the VNC server software:

sudo apt-get install tightvncserver

2. Start the VNC server:

tightvncserver :1

3. Set VNC password:

tightvncserver -passwd

4. Allow VNC connection in Linux firewall:

sudo ufw allow 5901/tcp

5. Connect using VNC client:

vncviewer remote_host_ip:1

3. RDP Remote Desktop Access
   RDP (Remote Desktop Protocol) is a protocol developed by Microsoft for remote access to Windows systems. However, we can achieve RDP remote desktop access on Linux by installing and configuring the xrdp package. Here are the steps to configure RDP remote desktop access:
4. Install the xrdp package:

sudo apt-get install xrdp

2. Start the xrdp service:

sudo service xrdp start

3. View xrdp service status:

sudo service xrdp status

4. Allow RDP connection in Linux firewall:

sudo ufw allow 3389/tcp

5. Connect using RDP client:

rdesktop remote_host_ip

Summary:
By configuring protocols such as SSH, VNC and RDP, we can achieve remote access on the Linux host. Using these remote access methods, we can easily operate and manage Linux hosts remotely. Hopefully the instructions and code examples provided in this article will help you successfully configure remote access.
