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