NAME tincd -- tinc VPN daemon SYNOPSIS tincd [-cdDKnsoLRU] [--config=DIR] [--no-detach] [--debug[=LEVEL]] [--net=NETNAME] [--option=[HOST.]KEY=VALUE] [--mlock] [--logfile[=FILE]] [--syslog] [--bypass-security] [--chroot] [--user=USER] [--help] [--version] DESCRIPTION This is the daemon of tinc, a secure virtual private network (VPN) project. When started, tincd will 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 tinc will install itself as a service, which will be restarted automatically after reboots. OPTIONS -c, --config=DIR Read configuration files from DIR instead of /usr/local/etc/tinc/. -D, --no-detach 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. -d, --debug[=LEVEL] Increase debug level or set it to LEVEL (see below). -n, --net=NETNAME Connect to net NETNAME. This will let tinc read all configuration files from /usr/local/etc/tinc/ NETNAME. Specifying . for NETNAME is the same as not specifying any NETNAME. -o, --option=[HOST.]KEY=VALUE Without specifying a HOST, this will set server configuration vari- able 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. -L, --mlock Lock tinc into main memory. This will prevent sensitive data like shared private keys to be written to the system swap files/parti- tions. This option is not supported on all platforms. --logfile[=FILE] Write log entries to a file instead of to the system logging facil- ity. If FILE is omitted, the default is /var/log/tinc.NETNAME.log. -s, --syslog When this option is is set, tinc uses syslog instead of stderr in --no-detach mode. --pidfile=FILENAME Store a cookie in FILENAME which allows tinc(8) to authenticate. If FILE is omitted, the default is /var/run/tinc.NETNAME.pid. --bypass-security Disables encryption and authentication of the meta protocol. Only useful for debugging. -R, --chroot With this option tinc chroots into the directory where network con- fig is located (/usr/local/etc/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. -U, --user=USER setuid to the specified USER after initialization. This option is not supported on all platforms. --help Display short list of options. --version Output version information and exit. SIGNALS ALRM Forces tincd to try to connect to all uplinks immediately. Usually tincd attempts to do this itself, but increases the time it waits between the attempts each time it failed, and if tincd didn't suc- ceed to connect to an uplink the first time after it started, it defaults to the maximum time of 15 minutes. HUP 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 --logfile option is used, this will also close and reopen the log file, useful when log rotation is used. DEBUG LEVELS The tinc daemon can send a lot of messages to the syslog. The higher the debug level, the more messages it will log. Each level inherits all mes- sages of the previous level: 0 This will log a message indicating tincd has started along with a version number. It will also log any serious error. 1 This will log all connections that are made with other tinc dae- mons. 2 This will log status and error messages from scripts and other tinc daemons. 3 This will log all requests that are exchanged with other tinc dae- mons. These include authentication, key exchange and connection list updates. 4 This will log a copy of everything received on the meta socket. 5 This will log all network traffic over the virtual private network. FILES /usr/local/etc/tinc/ Directory containing the configuration files tinc uses. For more information, see tinc.conf(5). /var/run/tinc.NETNAME.pid The PID of the currently running tincd is stored in this file. BUGS The BindToInterface option may not work correctly. The cryptography in tinc is not well tested yet. Use it at your own risk! If you find any bugs, report them to tinc@tinc-vpn.org. TODO A lot, especially security auditing.
