[tor-relays] tor relay + sslh

[Casper]

Hello,

I recently discovered an SSL multiplexer called "sslh":

"""
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 recognized. 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 multiplexer, or a switchboard. Its name
comes from its original function to serve SSH and HTTPS on the same port.
"""

Since many of my network services claims to listen on 433 (to bypass
mobile network limitations), I'm thinking to configure and deploy
sslh on large scale.

If tor handshake can be handled by sslh, could the process (of the tor
relay) be listening on 127.0.0.1:12345 and publish good relay
descriptor as well ?

Currently, in my relay config, I have the following:

"""
ORPort 26719
ORPort [{{ ansible_default_ipv6.address }}]:26719
DirPort 26720

and

Address <my_public_ipv4_here>
"""

Tor will accept to be listening on the localhost interface only?

"""
ORPort 127.0.0.1:26719
Address <my_public_ipv4_here>
"""

Best regards,
