# Teleport Signals

You can send the following signals to a `teleport` process to trigger different functionality.

To send a signal, execute the following command on the host where `teleport` is running, replacing `SIG` with the name of the signal.

```
$ kill -SIG
```

| Signal        | Teleport Daemon Behavior                                                                                                                                      |
| ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `USR1`        | Dumps diagnostics/debugging information into syslog.                                                                                                          |
| `QUIT`        | Graceful shutdown. The daemon will stop accepting new connections and it will wait (for up to 30 hours) until existing connections are closed before exiting. |
| `TERM`, `INT` | Immediate non-graceful shutdown. All existing connections will be closed after a very short delay.                                                            |
| `USR2`        | Forks a new Teleport daemon to serve new connections.                                                                                                         |
| `HUP`         | Forks a new Teleport daemon to serve new connections **and** initiates the graceful shutdown of the existing process, same as `SIGQUIT`.                      |
