I tested Java 6, 7, and 8 from the archives from
http://www.oracle.com/technetwork/java/archive-139210.html. If you use
the 32bit versions, they all work with MusicIP on Fedora 26, at least as
far as loading the GUI. There are several errors in loading which are
cosmetic only, and don't seem to affect the operation of MusicIP. I
haven't tried analysis yet, but I'll update this thread when I do.

Good news ! Yes, only the JRE works from my experience.
If you ever discover how to use the gui with a newer version of java,
that would interest me, because I'm trying to use on RPI and JRE1.5
doesn't exist on ARM.

Antoniop, you're a prince! SELinux is definitely the problem, only
changing it to "permissive" mode (as you outlined) , which lowers
security to non-enforced warnings, allows MusipIP to be run as a systemd
service before LMS at startup, works. I did this on two different
computers, and on one of them, changing SELinux to the wrong mode
"broke" it so that the computer would not boot. A lot of research and
time was required to find the solution, going to Grub and adding an
entry  selinux=0 allowed me to reboot and get MusicIP working. To anyone
doing this, I highly recommend that you have a complete image backup to
reinstall if you're going to try this. Installing LMS 7.91 on Fedora 26
with MusicIP is possible, but there are quite a few steps involved. I'm
going to try to summarize the process Antoniop was so kind to create to
make it easy to follow for anyone wanting to do so in the next few
days.

Now as far as the MusicMagicMixer GUI, I tried it out, but it didn't
work. No error message on the command line, but journal -xe showed:
tracker-store[3506]: Could not create FTS delete statement: no such

Yes it's a 32-bit app, but running on a 64bit system has never been a
problem, as far as I know.

The problem is with SELinux, which is a kind of enhanced security
system. It can find security problems almost everywhere ! (ironic).
su is usually used to log as root when you're not root, but in our case
we try to run a script not as root, when we are, because it's started at
boot.
It's a bit beyond my knowledge, because I never used SELinux, it's not
enabled on Mageia by default. I'll do some google search.
In the meantime,
Please check that the script in /etc/init.d/mmserver is owned by root :
$ ll /etc/init.d |grep mmser
-rwxr-xr-x 1 root root   918 Sep  2 00:01 mmserver
Most likely, the indications given with the error messages are not
enough to fix this.

I believe it's just a problem of file rights. Maybe you already checked
all this and sorry if I'll mention things that you already know.
The script must be run by a regular user, so the files rights should be
set accordingly. I noticed that vortex box uses root as the user to run
the script, but it's to be avoided. In case of a problem, a program run
by a standard user can't damage too much your system nor can be used as
a security breach.
You can notice that LMS owner is not root, but squeezeboxserver.
I noticed in your mmserver file you have the line
USER=m
I suppose m is not the right name of the user, but it has to be the real
user that will run the program. If not, you should correct it.
You should also leave the line :
su - $USER -c $MUSICHOME"MusicMagicServer start  & > /dev/null"
as it is, because it's fine.
It means that the executable MusicMagicServer will be run with user
$USER.
It's a bit strange that you can run it from a terminal but it fails at
startup.
You have to check that all files in  /opt/MusicMagicMixer/ either are
owned by $USER or this user has read and execute permissions on these
files.
Log in a terminal with the user login and check all files :

Code:

cd /opt/MusicMagicMixer/
  ls -la

gives you files owners and rights. The first field is file rights. the
first letter is file type, then you have rights for owner 3 letters
(Read, Write, eXecute), group and world. Then you have user owner and
group owner. So if owner is $USER, then you should have -rwx.. in
rights for scripts and executables, -rw-... for other files, if not you
should have rwx (rwx at the end, for world). But I recommend to have
user owner and group owner is $USER for all files and directories.
To do this, open a terminal, log as root and type (replacing  by
the actual user):

Code:

cd /opt
  chown -R  MusicMagicMixer/
  chgrp -R  MusicMagicMixer/



Hope this could help.

Re: [SlimDevices: Plugins] MusicIP Headless not running in Fedora 26 Linux - script/systemd issues

2017-09-02 Thread Antoniop

Your mmserver script looks ok.

But mmserver.service looks wrong.
Try the following, I don't have fedora, I'm with mageia, which is also
rpm-based, I think it should work.
Make sure that your script mmserver is located in dir /etc/init.d
And I would also remove all links to mmserver script first.
You can use this to find them :

Code:

$ find /etc/ -name "*mmserver" 2>/dev/null


Here is my mmserver.service :
/etc/systemd/system/mmserver.service :

Code:

[Unit]
  Description=MusicMagicServer
  After=squeezeboxserver.service
  Requires=squeezeboxserver.service 
  
  [Service]
  Type=oneshot
  RemainAfterExit=no
  ExecStart=/etc/init.d/mmserver start
  ExecStop=/etc/init.d/mmserver stop 
  
  [Install]
  WantedBy=multi-user.target



To enable it at boot , type as root user :

Code:

systemctl enable mmserver.service


status :


Code:

 systemctl status mmserver.service


start mmserver:

Code:

systemctl start mmserver.service 



If you can start mmserver as root with the systemctl command, that
should be ok.

To enable the java gui, download the 32 bits version of java jre 1-5 at
:
http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase5-419410.html
Its the Linux self-extracting file jre-1_5_0-linux-i586.bin
copy it in your MusicIp home, /opt/MusicMagicMixer/

and extract it by running the .bin 
in a terminal :

Code:

cd /opt/MusicMagicMixer/
  chmod u+x jre-1_5_0-linux-i586.bin
  ./jre-1_5_0-linux-i586.bin


it should create a jre1.5.0/ sub-directory
To run the java gui,
You'll have to type :

Code:

export JAVA_HOME=jre1.5.0/
  ./MusicMagicMixer



I made this very simple bash to run it easily :
(don't forget to make it runnable)
run_musicipgui.bsh

Code:

#!/bin/bash
  cd /opt/MusicMagicMixer/
  export JAVA_HOME=jre1.5.0/
  ./MusicMagicMixer


I hope that it will work. Sorry if my english is not very good.

Re: [SlimDevices: Plugins] MusicIP Headless not running in Fedora 26 Linux - script/systemd issues

2017-09-01 Thread matrixed99

Antoniop,

Thanks for the Java information. I've been running the MusicMagicMixer
GUI on a Windows laptop for years, writing the analysis to the files,
and running LMS and MusicIP on Fedora Linux. I'm going to try using Java
1.5 to run the GUI on Linux, as you have recommended.

The current status of my MusicIP install on Fedora 26 is that I can run
it manually successfully after startup, but it starts and then
immediately stops without error during startup. There are no errors, at
least that I have been able to find, viewing the logs with systemctl and
journalctl. Running the service after startup asks for a password, and
then loads MusicIP headless successfully. Here are the scripts and
logs:

Re: [SlimDevices: Plugins] MusicIP Headless not running in Fedora 26 Linux - script/systemd issues

2017-09-01 Thread Antoniop

Java is not necessary to run MusicIp headless. 
It's only needed if you want to run the gui "MusicMagicMixer" that is
located in the MusicIp directory and shows a quite similar to windows
gui.
It can run with java runtime 1.5 (jre 1.5) under linux, but I couldn't
get it to work with newer versions of java.

I think I tried to run it with wine but without success. Anyway, it's
not really necessary. Headless MusicIp is enough to create mixes and if
you want a gui to create moods and so an, you can use the java gui, I
would post the instructions then to have it running, it's quite simple.

Could you post the mmserver script, so I could have a look at it ?

Re: [SlimDevices: Plugins] MusicIP Headless not running in Fedora 26 Linux - script/systemd issues

2017-08-28 Thread matrixed99

Wirrunna,

So kind of you to send the script and links. The good news is, the
scripts worked! I previously was only able to load MusicIP by changing
to the /MusicMagicMixer directory and inputting ./MusicMagicServer start
in the terminal. With the script, I can run the script itself without
changing directories and am able to  start|stop MusicIP, but a password
is requested and required. It will not  to run at startup successfully.
I've tried a few approaches to correct this, but none have been
successful so far. 

1 - The stock init.d script doesn't run successfully after a reboot, or
login/logout

2 - Tried the following to convert original script to system.d
sysv.init.script.to.systemd.unit.file.md

Copy the file to /etc/init.d/mmserver.
Enable the SysV service: chkconfig --add mmserver.
Enable the SysV service: chkconfig mmserver on.
Start the service: service mmserver start .


This is also unsuccessful. The script runs and exits immediately each
time it is run, on the command line or after booting.

3. The creation of a new mmserver.service unit

I've tried many approaches new systemd scripts, none successfully. I've
tried different types (simple, forked, oneshot). All of them seem to
fail because the start process exits immediately after running. Even
when journalctl shows no errors, this is the case.

I use the MusicIP gui in Windows, and write the analysis to the flac
files before moving them the Linux server running LMS, so I only need
the headless MusicIP. I'm going to study systemd more carefully (sadly),
but some questions for anyone who might know:

Can MusicIP be run on Wine on the same machine as LMS and work with it?

Is Java used in the headless install of MusicIP?

If all else fails, manually running MusicIP and LMS would work, but
after having it run at startup for ten years, not a first choice.

matrixed99, have you got any further with this ?

The only help I can offer is Spicefly -

and the script that Vortexbox 2.4 supplied for Fedora 23.

[SlimDevices: Plugins] MusicIP Headless not running in Fedora 26 Linux - script/systemd issues

2017-08-21 Thread matrixed99

Has anyone had any success running MusicIP headless in Fedora 26? After
doing a clean install of Fedora, I'm unable to get the scripts to run. I
have tried running the scripts from /etc/init.d as is, attempted to
modify them to work, tried to convert the scripts to pure systemd
scripts that don't call the original scripts, and converting them to
systemd scripts, but without success. 

I am by no means an expert in Linux, but  have had a functioning LMS
server on Fedora 4 through 14 with MusicIP for 12 years. Most of the
errors have been "file not found" in referencing the original scrip in
many locations in many variations, but I've been able to get through
these. Much tougher has been the problem where the unit loads and
deactivated it self right away. I have tried service types of simple,
forking and one shot. The only way I can get it to run is on the command
line, changing to the /MusicMagicMixer directory, and running
./MusicMagicServer start/stop. 

When working with systemd to run the scripts in /etc/init.d, my
process looks something like this:

sudo systemctl disable /etc/systemd/system/mmserver.service
sudo nano /etc/init.d/mmserver
sudo systemctl enable /etc/systemd/system/mmserver.service
sudo systemctl daemon-reload

At this point, either:
reboot
Or:
sudo systemctl start mmserver.service

I use a similar approach when the systemd script calls the init.d
script

After many days of working with this, I'm at an impass. Anyone had any
success with this, or have any suggestions? 
Thanks!
