Enable SSH on Raspberry Pi and Access It Remotely Anywhere Using cpolar

How to Connect to Raspberry Pi via SSH

This article shows how to enable SSH on a Raspberry Pi, locate its IP address, and connect from another computer. It then introduces cpolar, an inner‑network tunneling tool, to expose the Pi’s SSH port to the public internet so you can access it from anywhere.

Step 1 – Enable SSH on the Raspberry Pi

SSH is disabled by default. Open the Raspberry Pi Configuration window from the menu, go to the Interfaces tab, enable SSH, and reboot the Pi.

You can also enable SSH from the terminal with sudo raspi-config and selecting the advanced option.

Step 2 – Find the Pi’s IP address

Use a command such as ifconfig (or ip address) to display the network adapters. The IP will look like 192.168.x.x (Ethernet) or 10.x.x.x (Wi‑Fi). You can also check your router’s device list.

Step 3 – SSH into the Pi

From another computer open a terminal (or PuTTY on Windows) and run: ssh [email protected] The default credentials are username: pi and password: raspberry. Change the password if you have modified it.

Step 4 – Access the Pi from Anywhere with cpolar

Install cpolar (a reverse‑proxy/ tunneling tool) using one of the following commands:

curl -L https://www.cpolar.com/static/downloads/install-release-cpolar.sh | sudo bash

or for overseas users: curl -sL https://git.io/cpolar | sudo bash Authenticate with your cpolar token: cpolar authtoken YOUR_TOKEN Enable the service to start on boot and launch it:

sudo systemctl enable cpolar
sudo systemctl start cpolar

Check the status: sudo systemctl status cpolar cpolar creates two sample tunnels – a web tunnel on port 8080 and an SSH tunnel on port 22. View the public SSH address in the cpolar dashboard (e.g., 1.tcp.vip.cpolar.cn with a generated port).

Connect remotely with: ssh [email protected] -p PORT_NUMBER After a successful login you can run commands on the Pi from any network (home, office, mobile 4G, etc.).

Optional – Change the Default Password

Run passwd on the Pi, enter the current password ( raspberry) and then the new password.

You may also configure SSH keys for password‑less login, which is beyond the scope of this guide.
