Security tips blog, security-hacks, has published an simple guide to share files securely in heterogeneous networks.
“Suppose you’re at a open wireless hotspot and wish to connect the Samba server from your Windows laptop, but you don’t want to send data (documents, authentication hashes etc.) over the air in plain text. Using SSH tunnels, you can encrypt all your network traffic and redirect it through a trusted computer when you’re connected to an untrusted network. The goal of this hack is to enable Windows users securely access shared files on any Samba server,” from security-hacks.com.
