How do I test SSH forwarding?

Testing SSH agent forwarding

Is SSH tunnel same as VPN?

VPNs and SSH systems both create secure “tunnels” for your data to travel through. These tunnels ensure that nobody other than the intended recipient can view or alter your data. However, while an SSH connection only works on an application level, a VPN connection encrypts and protects all your data.

Can Wireshark see SSH traffic?

Wireshark can be forced to decode any traffic as SSH by selecting Analyze → Decode As and setting the appropriate port type, port number and protocol.

How does SSH tunneling work?

SSH tunneling, or SSH port forwarding, is a method of transporting arbitrary data over an encrypted SSH connection. SSH tunnels allow connections made to a local port (that is, to a port on your own desktop) to be forwarded to a remote machine via a secure channel.
