.Op Fl -config Ns = Ns Ar DIR
.Op Fl -no-detach
.Op Fl -debug Ns Op = Ns Ar LEVEL
-.Op Fl -kill Ns Op = Ns Ar SIGNAL
.Op Fl -net Ns = Ns Ar NETNAME
-.Op Fl -generate-keys Ns Op = Ns Ar BITS
+.Op Fl -option Ns = Ns Ar [HOST.]KEY=VALUE
.Op Fl -mlock
.Op Fl -logfile Ns Op = Ns Ar FILE
-.Op Fl -pidfile Ns = Ns Ar FILE
+.Op Fl -syslog
.Op Fl -bypass-security
.Op Fl -chroot
.Op Fl -user Ns = Ns Ar USER
Increase debug level or set it to
.Ar LEVEL
(see below).
-.It Fl k, -kill Ns Op = Ns Ar SIGNAL
-Attempt to kill a running
-.Nm
-(optionally with the specified
-.Ar SIGNAL
-instead of SIGTERM) and exit.
-Under Windows (not Cygwin) the optional argument is ignored,
-the service will always be stopped and removed.
.It Fl n, -net Ns = Ns Ar NETNAME
Connect to net
.Ar NETNAME .
.Ar NETNAME
is the same as not specifying any
.Ar NETNAME .
-.It Fl K, -generate-keys Ns Op = Ns Ar BITS
-Generate public/private RSA keypair and exit.
-If
-.Ar BITS
-is omitted, the default length will be 2048 bits.
-When saving keys to existing files, tinc will not delete the old keys,
-you have to remove them manually.
+.It Fl o, -option Ns = Ns Ar [HOST.]KEY=VALUE
+Without specifying a
+.Ar HOST ,
+this will set server configuration variable
+.Ar KEY
+to
+.Ar VALUE .
+If specified as
+.Ar HOST.KEY=VALUE ,
+this will set the host configuration variable
+.Ar KEY
+of the host named
+.Ar HOST
+to
+.Ar VALUE .
+This option can be used more than once to specify multiple configuration variables.
.It Fl L, -mlock
Lock tinc into main memory.
This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.
+This option is not supported on all platforms.
.It Fl -logfile Ns Op = Ns Ar FILE
Write log entries to a file instead of to the system logging facility.
If
.Ar FILE
is omitted, the default is
.Pa @localstatedir@/log/tinc. Ns Ar NETNAME Ns Pa .log.
-.It Fl -pidfile Ns = Ns Ar FILE
-Write PID to
+.It Fl s, -syslog
+When this option is is set, tinc uses syslog instead of stderr in --no-detach mode.
+.It Fl -pidfile Ns = Ns Ar FILENAME
+Store a cookie in
+.Ar FILENAME
+which allows
+.Xr tinc 8
+to authenticate.
+If
.Ar FILE
-instead of
+is omitted, the default is
.Pa @localstatedir@/run/tinc. Ns Ar NETNAME Ns Pa .pid.
-Under Windows this option will be ignored.
.It Fl -bypass-security
Disables encryption and authentication of the meta protocol.
Only useful for debugging.
With this option tinc chroots into the directory where network
config is located (@sysconfdir@/tinc/NETNAME if -n option is used,
or to the directory specified with -c option) after initialization.
+This option is not supported on all platforms.
.It Fl U, -user Ns = Ns Ar USER
setuid to the specified
.Ar USER
after initialization.
+This option is not supported on all platforms.
.It Fl -help
Display short list of options.
.It Fl -version
New outgoing connections specified in
.Pa tinc.conf
will be made.
-.It INT
-Temporarily increases debug level to 5.
-Send this signal again to revert to the original level.
-.It USR1
-Dumps the connection list to syslog.
-.It USR2
-Dumps virtual network device statistics, all known nodes, edges and subnets to syslog.
-.It WINCH
-Purges all information remembered about unreachable nodes.
+If the
+.Fl -logfile
+option is used, this will also close and reopen the log file,
+useful when log rotation is used.
