.Sh DESCRIPTION
The
.Nm
daemon processes messages from other federated servers.
This is the admin manual.
For user operation, see
.Xr honk 1 .
.Ss SETUP
.Pp
Set up a TLS reverse proxy.
.Nm
can listen on TCP or unix sockets, but will not terminate TLS.
https is a required component for federation.
.Pp
Make sure to pass the Host header, if necessary (as for nginx).
.Bd -literal -offset indent
proxy_set_header Host $http_host;
.Ed
.Ss BUILD
Building
.Nm
requires a go compiler and libsqlite.
On
.Ox
this is the go and sqlite3 packages.
Other platforms may require additional development libraries or headers
to be installed.
Run make.
Please be patient.
Even on fast machines, building from source can take several seconds.
.Ss INIT
Run the
.Ic init
command.
.Dl ./honk init
This will create the database and ask four questions, as well as creating
the initial user.
.Bd -literal -offset indent
username: (desired username)
password: (desired password)
listenaddr: (tcp or unix: localhost:31337, /var/www/honk.sock, etc.)
servername: (public DNS name: honk.example.com)
.Ed
.Ss OPERATION
Run honk.
.Dl date; ./honk >> log 2>&1
