This option may not work on all platforms.
-.It Va BlockingTCP Li = yes | no Po no Pc Bq experimental
-This options selects whether TCP connections, when established, should use blocking writes.
-When turned off, tinc will never block when a TCP connection becomes congested, but will have to terminate that connection instead.
-If turned on, tinc will not terminate connections but will block, thereby unable to process data to/from other connections.
-Turn this option on if you also use
-.Va TCPOnly
-and tinc terminates connections frequently.
.It Va ConnectTo Li = Ar name
Specifies which other tinc daemon to connect to on startup.
Multiple
.Va Device .
The info pages of the tinc package contain more information
about configuring the virtual network device.
+.It Va GraphDumpFile Li = Ar filename Bq experimental
+If this option is present,
+.Nm tinc
+will dump the current network graph to the file
+.Ar filename
+every minute, unless there were no changes to the graph.
+The file is in a format that can be read by graphviz tools.
+If
+.Ar filename
+starts with a pipe symbol |,
+then the rest of the filename is interpreted as a shell command
+that is executed, the graph is then sent to stdin.
.It Va Hostnames Li = yes | no Pq no
This option selects whether IP addresses (both real and on the VPN) should
be resolved. Since DNS lookups are blocking, it might affect tinc's
.It Va Name Li = Ar name Bq required
This is the name which identifies this tinc daemon.
It must be unique for the virtual private network this daemon will connect to.
-.It Va PingTimeout Li = Ar seconds Pq 60
+.It Va PingInterval Li = Ar seconds Pq 60
The number of seconds of inactivity that
.Nm tinc
will wait before sending a probe to the other end.
-If that other end doesn't answer within that same amount of time,
+.It Va PingTimeout Li = Ar seconds Pq 5
+The number of seconds to wait for a response to pings or to allow meta
+connections to block. If the other end doesn't respond within this time,
the connection is terminated,
and the others will be notified of this.
.It Va PriorityInheritance Li = yes | no Po no Pc Bq experimental
.Bl -tag -width indent
.It Va Address Li = Ar address Bq recommended
The IP address or hostname of this tinc daemon on the real network.

becomes unreachable.
+.It Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /host-up
+This script is started when any host becomes reachable.
+.It Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /host-down
+This script is started when any host becomes unreachable.
+.It Pa @sysconfdir@/tinc/ Ns Ar NETNAME Ns Pa /subnet-up
+This script is started when a Subnet becomes reachable.
+The Subnet and the node it belongs to are passed in environment variables.

+This script is started when a Subnet becomes unreachable.

The scripts are started without command line arguments, but can make use of certain environment variables.
.Pa ifconfig .
.It Ev NODE
When a host becomes (un)reachable, this is set to its name.
+If a subnet becomes (un)reachable, this is set to the owner of that subnet.
.It Ev REMOTEADDRESS
When a host becomes (un)reachable, this is set to its real address.
.It Ev REMOTEPORT
When a host becomes (un)reachable, this is set to the port number it uses for communication with other tinc daemons.
+.It Ev SUBNET
+When a subnet becomes (un)reachable, this is set to the subnet.
