Liquidsoap errors

    Hi All,

    We've installed airtime using the 'full-installation' script and despite that all going OK, we're having problems getting liquidsoap running.
    airtime-check-system shows that liquidsoap is not running despite all the other services checking out OK;

    <code>sudo airtime-check-system
    AIRTIME_STATUS_URL             = http://localhost:8442/api/status/format/json/api_key/%%api_key%%

    When we try re/starting liquidsoap manually, there's an odd error about the '-f' switch not being recognised. I've looked through the configs and can't find where the '-f' is being passed to liquidsoap.

    <code> sudo invoke-rc.d airtime-liquidsoap start-with-monit
    Starting Liquidsoap Playout Engine: no more csLADSPA plugins
    /usr/bin/airtime-liquidsoap: unknown option `-f'.
    Usage : liquidsoap [OPTION, SCRIPT or EXPR]...
     - SCRIPT for evaluating a liquidsoap script file;
     - EXPR for evaluating a scripting expression;
     - OPTION is one of the options listed below:</code>

    ...it then lists the config options for liquidsoap and natually '-f' is not listed amongst them. Anyone have an idea why we're getting this error ?

    Thanks in advance !

    I found where the -f switch was coming from..
    nano /usr/lib/airtime/pypo/bin/airtime-liquidsoap

    Removing it didn't help though :)

    sudo invoke-rc.d airtime-liquidsoap start-with-monit
    Starting Liquidsoap Playout Engine: no more csLADSPA plugins
    File "library/pervasives.liq", line 1, char 21 before "\"utils.liq\"": Unknown error.
    Fatal error: exception Sys_error("utils.liq: No such file or directory")

    Done.

    *Bump*

    I removed and reinstalled airtime from scratch and I'm still not able to restart/start airtime-liquidsoap.. Although just to add, restarting the service causes a different error;

    sudo service airtime-liquidsoap restart
    Restarting Liquidsoap Playout Engine: ('Error loading config file: %s', error(111, 'Connection refused'))

    none of the searches of this error have revealed a workable fix though.

    Cheers

    "Connection refused"?

    Could it be that your Icecast daemon isn't running?

    Thanks for the suggestion. You're right that icecast isn't running, but I'm using shoutcast instead of icecast. I have successfully a) connected to the shoutcast instance using the DSP plugin for winamp with the same credentials and b) successfully used the same configuration in a VM instance. The problem arises when I try to use the same setup on our production server...

    In the airtime > system > streams tab, all I get is "Getting information from the server..." despite being able to connect to the same from a source other than airtime.

    Why is your AIRTIME_STATUS_URL at port 8442?

    Hi Roger, that was because I was initially trying to use a non-standard port and as such changed the config files to suit (as I had successfully done with the install on the VM). When I removed and reinstalled airtime I used the default ports and have the same errors. Here's the check system run again showing port 80;

    # sudo airtime-check-system
    AIRTIME_STATUS_URL             = http://localhost:80/api/status/format/json/api_key/%%api_key%%

    Same error when restarting liquidsoap

    # sudo invoke-rc.d airtime-liquidsoap restart
    Restarting Liquidsoap Playout Engine: ('Error loading config file: %s', error(111, 'Connection refused'))
    no more csLADSPA plugins
    /usr/bin/airtime-liquidsoap: unknown option `-f'.
    Usage : liquidsoap [OPTION, SCRIPT or EXPR]...

    and the streams config still shows 'Getting information from the server...' which it isn't.

    Ok, I finally worked out what was causing the problem. Posting this in the hope it might help someone else. I found a long forgotten version of liquidsoap compiled from source on the server in;

    /usr/local/bin/liquidsoap

    that was overriding the version installed from the repositories. Now it's been removed, the version from the repo is reported correctly by which;

    # which liquidsoap
    /usr/bin/liquidsoap

    and liquidsoap is connecting to the shoutcast streams as it should (cue slow hand-clap).
