SSH Tunnel Setup for Linux
Complete guide to configuring SSH tunneling on Linux using Terminal
📋 Before You Begin
Ensure you have your username and SSH password ready. You'll need your SSH server hostname (provided via email when you requested SSH access), username, and password to connect to our secure SSH proxy servers.
Important: All SSH proxy servers are under the cotse.net domain. The codamail.com domain is exclusively for email services. SSH access must be requested separately from your email account.
📦 Step 1: SSH Client Installation
Most Linux distributions include SSH by default. If not installed, use your distribution's package manager:

🚀 Step 3: Establish SSH Connection
First Connection:
ECDSA key fingerprint is SHA256:example_fingerprint_here.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
Connection Success: Once connected, you'll see a shell prompt or the connection will appear to "hang" - this is normal and means your tunnel is active.
