.Sh NAME
.Nm tpd
.Nd tesseras-paste daemon
.Sh SYNOPSIS
.Nm
.Op Fl g
.Op Fl n
.Op Fl p Ar port
.Op Fl d Ar dir
.Op Fl s Ar sock
.Op Fl w Ar http_port
.Op Fl b Ar host:port
.Sh DESCRIPTION
.Nm
is the tesseras-paste daemon.
It participates in the tesseras-dht distributed hash table network
to store and serve encrypted pastes.
It listens on a Unix domain socket for commands from
.Xr tp 1
and optionally serves an HTTP interface.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl b Ar host:port
Bootstrap peer address.
This option can be specified multiple times to connect to
several peers at startup.
When specified, automatic SRV discovery is skipped.
.It Fl d Ar dir
Data directory for paste storage and identity key.
The default is
.Pa /var/tesseras-paste .
.It Fl g
Enable global NAT mode for public servers.
.It Fl n
Disable automatic bootstrap via DNS SRV discovery.
By default, when no
.Fl b
peers are given,
.Nm
queries the SRV record at
.Em _tesseras._udp.tesseras.net
to discover bootstrap peers.
This flag disables that behavior, useful for running an isolated node.
.It Fl p Ar port
UDP port for the DHT protocol.
A value of 0 selects a random port.
The default is 0.
.It Fl s Ar sock
Path to the Unix domain socket.
The default is
.Pa daemon.sock
inside the data directory.
.It Fl w Ar http_port
Enable the HTTP server on the specified port.
.El
.Sh BOOTSTRAP DISCOVERY
When no
.Fl b
peers are specified and
.Fl n
is not set,
.Nm
automatically discovers bootstrap peers by querying the DNS SRV record
.Em _tesseras._udp.tesseras.net .
.Sh FILES
.Bl -tag -width "/var/tesseras-paste/identity.key" -compact
.It Pa /var/tesseras-paste/
Default data directory.
.It Pa /var/tesseras-paste/daemon.sock
Default Unix domain socket.
.It Pa /var/tesseras-paste/identity.key
Persistent Ed25519 identity key.
Generated automatically on first run.
.El
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
Start the daemon with default settings:
.Pp
.Dl # tpd
.Pp
Start with a bootstrap peer and HTTP interface:
.Pp
.Dl # tpd -b 198.51.100.1:6881 -w 8080
.Pp
Start as a public server on port 6881:
.Pp
.Dl # tpd -g -p 6881
.Pp
Start an isolated node without automatic bootstrap:
.Pp
.Dl # tpd -n
