## Test tones {#tones}
|
||
|
||
If you need to test your computer's soundcard, you can use `speaker-test`, a tone generator for ALSA.
|
||
This does not come installed with LibreTime but can be installed with `sudo apt install speaker-test`.
|
||
|
||
```
|
||
speaker-test [-D] [-f]
|
||
|
||
Where:
|
||
-D device name
|
||
-f frequency of test tone
|
||
```
|
||
|
||
The **airtime-test-stream** command enables you to send a test tone to a local or remote streaming media server. Press **Ctrl+C** on your keyboard to stop the tone being streamed.
|
||
```
|
||
airtime-test-stream [-v]
|
||
[-o icecast | shoutcast ] [-H hostname] [-P port]
|
||
[-u username] [-p password] [-m mount]
|
||
[-h]
|
||
Where:
|
||
-v verbose mode
|
||
-o stream server type (default: icecast)
|
||
-H hostname (default: localhost)
|
||
-P port (default: 8000)
|
||
-u user (default: source)
|
||
-p password (default: hackme)
|
||
-m mount (default: test)
|
||
-h show help menu
|
||
```

## RabbitMQ hostname changes
|
||
|
||
If the Airtime logs indicate failures to connect to the RabbitMQ server, such as:
|
||
```
|
||
2013-10-31 08:21:11,255 ERROR - [pypomessagehandler.py : main() : line
|
||
99] - Error connecting to RabbitMQ Server. Trying again in few seconds
|
||
|
||
2013-10-31 08:21:11,255 ERROR - \[pypomessagehandler.py : main() : line 99\] - Error connecting to RabbitMQ Server. Trying again in few seconds - See more at: http://forum.sourcefabric.org/discussion/16050/\#sthash.W8OJrNFm.dpuf
|
||
```
|
||
but the RabbitMQ server is running normally, this error might be due to a change in the server's hostname since Libretime installation. Directory names under */var/lib/rabbitmq/mnesia/* indicate that RabbitMQ's database files are organised according to the hostname of the server (ex. `rabbit@airtime`) where the hostname is *airtime.example.com*. If the hostname has changed, it may be necessary to reconfigure RabbitMQ manually, as follows:
|
||
|
||
1. Delete the files in */var/lib/rabbitmq/mnesia/*
|
||
|
||
```
|
||
sudo rm -r /var/lib/rabbitmq/mnesia/*
|
||
```
|
||
|
||
2. Restart RabbitMQ:
|
||
|
||
```
|
||
sudo systemctl restart rabbitmq-server
|
||
```
|
||
|
||
3. Enter the following commands to set up authentication and grant permissions. The *rabbitmqctl add\_user* command requires the RabbitMQ password from the /etc/airtime/airtime.conf file as an argument. The *rabbitmqctl set\_permissions* command should be entered on one line, with the list of Airtime services repeated three times:
|
||
|
||
```
|
||
rabbitmqctl add_vhost /airtime
|
||
rabbitmqctl add_user airtime XXXXXXXXXXXXXXXXXXXX
|
||
rabbitmqctl set_permissions -p /airtime airtime
|
||
"airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
|
||
"airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
|
||
"airtime-pypo|pypo-fetch|airtime-analyzer|media-monitor"
|
||
``` |
