How to Fix: SSH -L connection successful, but localhost port forwarding not working "channel 3: open failed: connect failed: Connection refused"
📋 Table of Contents
To resolve the issue of SSH -L connection successful, but localhost port forwarding not working due to a 'channel 3: open failed: connect failed: Connection refused' error, you need to understand that this is often caused by a conflict between the SSH server's configuration and your local router's firewall settings.
🔍 Why This Happens
- When you initially connected to the server from your cousin's house, it was likely that the VPN setup allowed the SSH connection to bypass the router's firewall.
🔧 Proven Troubleshooting Steps
Method 1: Configure SSH Port Forwarding on the Server
- Step 1: On your Mac, open the Terminal app and run the command `ssh -L
: :localhost:8080` (replace ` ` with your server username and ` ` with the desired port number). This sets up a port forwarding from the local machine to the remote server.
Method 2: Configure Your Router's Firewall
- Step 1: Open your router's configuration page and navigate to the 'Advanced' or 'Security' section. Look for a setting related to 'SSH Port Forwarding' or 'Remote Access'. Enable this feature, if available.
✨ Wrapping Up
By following these steps, you should be able to resolve the issue of SSH -L connection successful, but localhost port forwarding not working. If the problem persists, it may be worth consulting with your network administrator or IT department for further assistance.
