.SH "DESCRIPTION"
.sp
\fBanytun\-controld\fR configures the multi\-connection support for \fBAnytun\fR\&. It reads a connection/routing table and outputs it via a tcp socket to all connected \fBAnytun\fR servers\&. When the control daemon is restarted with a new connection/routing table all \fBAnytun\fR servers automatically load the new configuration\&. Please make sure to protect that information as it contains the connection keys\&.
.SH "OPTIONS"
.PP
\fB\-D, \-\-nodaemonize\fR
.RS 4
This option instructs
\fBanytun\-controld\fR
to run in foreground instead of becoming a daemon which is the default\&.
.RE
.PP
\fB\-u, \-\-username \fR\fB\fI<username>\fR\fR
.RS 4
run as this user\&. If no group is specified (\fB\-g\fR) the default group of the user is used\&. The default is to not drop privileges\&.
.RE
.PP
\fB\-g, \-\-groupname \fR\fB\fI<groupname>\fR\fR
.RS 4
run as this group\&. If no username is specified (\fB\-u\fR) this gets ignored\&. The default is to not drop privileges\&.
.RE
.PP
\fB\-C, \-\-chroot \fR\fB\fI<path>\fR\fR
.RS 4
Instruct
\fBanytun\-controld\fR
to run in a chroot jail\&. The default is to not run in chroot\&.
.RE
.PP
\fB\-P, \-\-write\-pid \fR\fB\fI<filename>\fR\fR
.RS 4
Instruct
\fBanytun\-controld\fR
to write it\(cqs pid to this file\&. The default is to not create a pid file\&.
.RE
.PP
\fB\-L, \-\-log \fR\fB\fI<target>:<level>[,<param1>[,<param2>[\&.\&.]]]\fR\fR
.RS 4
add log target to logging system\&. This can be invoked several times in order to log to different targets at the same time\&. Every target hast its own log level which is a number between 0 and 5\&. Where 0 means disabling log and 5 means debug messages are enabled\&.

The file target can be used more the once with different levels\&. If no target is provided at the command line a single target with the config
\fIsyslog:3,anytun\-controld,daemon\fR
is added\&.

The following targets are supported:
.PP
\fIsyslog\fR
.RS 4
log to syslog daemon, parameters <level>[,<logname>[,<facility>]]
.RE
.PP
\fIfile\fR
.RS 4
log to file, parameters <level>[,<path>]
.RE
.PP
\fIstdout\fR
.RS 4
log to standard output, parameters <level>
.RE
.PP
\fIstderr\fR
.RS 4
log to standard error, parameters <level>
.RE
.RE
.PP
\fB\-U, \-\-debug\fR
.RS 4
This option instructs
\fBAnytun\fR
to run in debug mode\&. It implicits
\fB\-D\fR
(don\(cqt daemonize) and adds a log target with the configuration
\fIstdout:5\fR
(logging with maximum level)\&. In future releases there might be additional output when this option is supplied\&.
.RE
.PP
\fB\-f, \-\-file \fR\fB\fI<path>\fR\fR
.RS 4
The path to the file which holds the sync information\&.
.RE
.PP
\fB\-X, \-\-control\-host \fR\fB\fI<hostname|ip>[:<port>]\fR\fR
.RS 4
fetch the config from this host\&. The default is not to use a control host and therefore this is empty\&. Mind that the port can be omitted in which case port 2323 is used\&. If you want to specify an ipv6 address and a port you have to use [ and ] to separate the address from the port, eg\&.: [::1]:1234\&. If you want to use the default port [ and ] can be omitted\&.
.RE
.SH "BUGS"
.sp
Most likely there are some bugs in \fBAnytun\fR\&. If you find a bug, please let the developers know at satp@anytun\&.org\&. Of course, patches are preferred\&.
