A tunneling protocol is a Network Protocol which Encapsulates one protocol or session inside another. Protocol A is encapsulated within protocol B, such that A treats B as though it were a Data Link Layer . Tunneling may be used to transport a network protocol through a network which would not otherwise support it. Tunnelling may also be used to provide various types of VPN functionality such as private addressing. Examples include: Datagram -based:
Stream -based: SSH TUNNELING SSH is frequently used to tunnel insecure traffic over the Internet in a secure way. For example, Windows machines can share files using the Samba (SMB) protocol, which is not encrypted. If you were to mount a Windows filesystem remotely through the Internet, someone snooping on the connection could see your files. So to mount a SMB file system securely, one can establish an SSH tunnel that routes all SMB traffic to the fileserver inside an SSH-encrypted connection. Even though the SMB traffic itself is insecure, because it travels within an encrypted connection it becomes secure. SEE ALSO REFERENCES |
