Hi Wayne,
Thanks for taking the time to write out the instructions.
I cannot find the mysql folder under /etc/
Since I am using the Beta version of the broadcast appliance, I have 
read that it uses a different database, Maria - or something.
Also, I used the apt-get install nfs command and this did not work 
(command not found).
Is it possible the Beta appliance is a different setup?
Thanks,
Hugh

Re: [RDD] Where to get Audacity (autio file editor) that will happily co-exist on Rivendell Broadcast Appliance

[Richard Gorbutt]

I was never ever able to get Audacity to co-exist on the appliance version
(CentOS6), even attempting to compiling it, failing miserably as it wanted
some dependencies that Rivendell would not be happy with. Rather than let
it become a huge Science project I migrated to Linux Mint 17 and have been
happy ever since.,

Now that was a year or so ago, so things may have changed. Good luck.

[RDD] Where to get Audacity (autio file editor) that will happily co-exist on Rivendell Broadcast Appliance

[Rick Thomas]

I have installed the Rivendell "Broadcast Appliance" DVD.  I'd like to be able 
to edit audio files on the same machine using Audacity.

Does anyone here know if there is a rpm or CentOS-6 compatible repository from 
which I can install Audacity?

Thanks!

Hi Don,

This is one of those "unusual" instances in which a command cares about
spacing with respect to command line parameters.

The mysql "password" option requires *no* space after the "-p" (so, just
as you entered it below). Most command options with arguments accept
spacing or not, and many accept an '=' between the option and its
argument (with no spaces surrounding the '='). Manual pages are your
friend when you don't have the source.

Hope this helps!

I tried that . At mysql -h "ip" -u rduser -pletmein Rivendell I get Host
'onair.router' is not allowed to connect to this MySQL server. I have
deleted all MySQL components off the onair machine. On the server MySQL I
have a  rduser@localhost user. I really appreciate your help! It's a

Re: [RDD] AirPlay and Production Link

[Wayne Merricks]

Hi,

Lets assume: On Air Machine IP = 10.0.0.2 and the Server IP is 10.0.0.1 
(replace with whatever IP addresses you have)


On the on air machine:

$ mysql -h 10.0.0.1 -u rduser -pletmein Rivendell

That should let you log into mysql on the Rivendell database.  If it 
doesn't then the only explanation is that you either changed the default 
letmein password or your on air machine is using a local database and 
not the server.


$ mysql -u rduser -pletmein Rivendell

If that connects it is definitely using a local database (otherwise 
your on air machine wouldn't be playing out).


Just in case, rduser is the user name Rivendell uses for the database, 
this is nothing to do with your Linux user (which in your case might be 
onair judging by your error message?).


Regards,

Wayne

All you need to do is share the database and the /var/snd directory
between the two machines.  Then add your new machine to rdadmin.

First  the easier bit of the two.

On the production machine

Check that you can talk to the on air mysql database:

$ mysql -h ip_or_hostname_of_on_air_machine -u rduser -pletmein

If it lets you connect great.  If not check that mysql is set to
listen to the network:

On the on air machine (only if you cant connect)

$ sudo nano /etc/mysql/my.cnf

Find the line bind-address = 127.0.0.1 and change it to 0.0.0.0

Then restart the mysql service (this may disrupt Rivendell if it
does any DB work while you do this, in theory if youre in the middle
of a song playing you should be fine).

On the production machine (skip to here if you can connect)

Assuming you can now access mysql from here, change rd.conf to look
at the remote MySQL:

$ nano /etc/rd.conf

Find this bit:

[mySQL]
Hostname=localhost

And change it to the address of your on air machine.

On the on air machine

With that out of the way, you need to share the /var/snd
directory.  The easiest thing to use is NFS (similar to windows
network shares but it works more reliably). 

You might have to install nfs (sudo apt-get install
nfs-kernel-server), assuming that is already there:

$ sudo nano /etc/exports

Add the line (amend this for your network mine is 10.43.X.X, so I
do this):

/var/snd 10.43.0.0/255.255.0.0(rw,sync,all_squash,subtree_check)
[1]

Then "export" the share:

$ sudo exportfs -r -v

And it should say exported /var/snd.

On the production machine

Now all you need to do is mount the remote /var/snd to the local
/var/snd.  Make sure youve installed the NFS client (sudo apt-get
install nfs-common).  Then test mount it:

$ sudo mount -t nfs ip_or_name_of_on_air_machine:/var/snd /var/snd

if that works youll see all your on air audio inside /var/snd.

To permanently mount /var/snd (so that it sticks between reboots):

$ sudo nano /etc/fstab

Add the line:

ip_or_name_of_on_air_machine:/var/snd /var/snd nfs
rsize=32768,wsize=32768,timeo=14,intr

Finally, load up rdadmin on either machine and add a new host. 
Make sure it is the same name as your production machine and set it
up how you want it to work.  You may get a message about missing
audio assignments.  Thats OK, as soon as the Rivendell daemons are
restarted it will add itself to the database.

That is all you have to do to share amongst machines.
