|TINCD(8)||System Manager's Manual||TINCD(8)|
tincdwill read it's configuration file to determine what virtual subnets it has to serve and to what other tinc daemons it should connect. It will connect to the ethertap or tun/tap device and set up a socket for incoming connections. Optionally a script will be executed to further configure the virtual device. If that succeeds, it will detach from the controlling terminal and continue in the background, accepting and setting up connections to other tinc daemons that are part of the virtual private network. Under Windows (not Cygwin) tinc will install itself as a service, which will be restarted automatically after reboots.
- Read configuration files from DIR instead of /etc/tinc/.
- Don't fork and detach. This will also disable the automatic restart mechanism for fatal errors. If not mentioned otherwise, this will show log messages on the standard error output.
- Increase debug level or set it to LEVEL (see below).
- Attempt to kill a running
tincd(optionally with the specified SIGNAL instead of SIGTERM) and exit. Under Windows (not Cygwin) the optional argument is ignored, the service will always be stopped and removed.
- Connect to net NETNAME. This will let tinc read all configuration files from /etc/tinc/ NETNAME. Specifying . for NETNAME is the same as not specifying any NETNAME.
- Generate public/private RSA keypair and exit. If 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.
- Without specifying a HOST, this will set server configuration variable KEY to VALUE. If specified as HOST.KEY=VALUE, this will set the host configuration variable KEY of the host named HOST to VALUE. This option can be used more than once to specify multiple configuration variables.
- Lock tinc into main memory. This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.
- Write log entries to a file instead of to the system logging facility. If FILE is omitted, the default is /var/log/tinc.NETNAME.log.
- Write PID to FILE instead of /var/run/tinc.NETNAME.pid. Under Windows this option will be ignored.
- 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 (/etc/tinc/NETNAME if -n option is used, or to the directory specified with -c option) after initialization.
- setuid to the specified USER after initialization.
- Display short list of options.
- Output version information and exit.
tincdto try to connect to all uplinks immediately. Usually
tincdattempts to do this itself, but increases the time it waits between the attempts each time it failed, and if
tincddidn't succeed to connect to an uplink the first time after it started, it defaults to the maximum time of 15 minutes.
- Partially rereads configuration files. Connections to hosts whose host
config file are removed are closed. New outgoing connections specified in
tinc.conf will be made. If the
--logfileoption is used, this will also close and reopen the log file, useful when log rotation is used.
- Temporarily increases debug level to 5. Send this signal again to revert to the original level.
- Dumps the connection list to syslog.
- Dumps virtual network device statistics, all known nodes, edges and subnets to syslog.
- Purges all information remembered about unreachable nodes.
- This will log a message indicating
tincdhas started along with a version number. It will also log any serious error.
- This will log all connections that are made with other tinc daemons.
- This will log status and error messages from scripts and other tinc daemons.
- This will log all requests that are exchanged with other tinc daemons. These include authentication, key exchange and connection list updates.
- This will log a copy of everything received on the meta socket.
- This will log all network traffic over the virtual private network.
- Directory containing the configuration files tinc uses. For more information, see tinc.conf(5).
- The PID of the currently running
tincdis stored in this file.
