| pascal@19628 | 1 `sslh` accepts connections on specified ports, and forwards |
| pascal@19628 | 2 them further based on tests performed on the first data |
| pascal@19628 | 3 packet sent by the remote client. |
| pascal@19628 | 4 |
| pascal@19628 | 5 Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are |
| pascal@19628 | 6 implemented, and any other protocol that can be tested using |
| pascal@19628 | 7 a regular expression, can be recognised. A typical use case |
| pascal@19628 | 8 is to allow serving several services on port 443 (e.g. to |
| pascal@19628 | 9 connect to SSH from inside a corporate firewall, which |
| pascal@19628 | 10 almost never block port 443) while still serving HTTPS on |
| pascal@19628 | 11 that port. |
| pascal@19628 | 12 |
| pascal@19628 | 13 Hence `sslh` acts as a protocol demultiplexer, or a |
| pascal@19628 | 14 switchboard. Its name comes from its original function to |
| pascal@19628 | 15 serve SSH and HTTPS on the same port. |
