Hi Adolf. We have looked at your work. First of all, thank you very much. Your scripts seems to work fine. I will start tomorrow to test them in whole. However we have made a few changes. In particular, we have adapted the code to the existing code in IPFire. Please take look at Michaels wsdd branch. https://git.ipfire.org/?p=people/ms/ipfire-2.x.git;a=shortlog;h=refs/heads/w... https://git.ipfire.org/?p=people/ms/ipfire-2.x.git;a=shortlog;h=refs/heads/wsdd
That looks very good. I clearly still have a bit to learn about how to code in a more tidy manner.
It worked… I was just in the swing of it :)
I also see that Michael fixed the pid fault in the loadproc/statusproc/killproc while I just created a workaround solution for the wsdd initscript alone.
loadproc/statusproc/killproc are really difficult to handle. They are supposed to be LSB-conformant functions, but I believe that it never really happened that they because universally used and compatible between distributions. Now with systemd, there is no more need…
And it is also because of systemd that daemons behave differently now - actually not even like daemons whatsoever any more. They used to fork themselves into the background which made all the PID processing necessary, because the init script could not know the PID of the process forked in the background. Now, they don’t do this any more because without the fork, things are easier for systemd to manage.
The new -b switch that was added some while ago is already helping us to launch such new processes into the background, but we don’t have PID files any more. And since scripts don’t work with statusproc/killproc, I thought it might be a good idea to add this to loadproc as I am expecting us to need this more often in the future.
And while I was thinking about the problem, I figured it would be easier to send a patch for those few lines instead of explaining it in words - which probably would have been a little bit longer.
The only noteworthy thing is that there was a potential security issue in passing around the shell arguments as strings because the workgroup variable could have been almost anything. I am not sure what validation samba would do, but I thought it would be best not to rely on that. A two words (with a space) workgroup would have caused wsdd not to start, because it would have seen a command line like “—-workgroup ABC DEF” with ABC being interpreted as the workgroup and DEF being some garbage that wsdd would not understand. The trick with the array is that it would pass the arguments like this “—-workgroup ‘ABC DEF’” which prevents that “DEF” would be interpreted as an extra parameter.
So, everything is fine :) Especially after I added the “restart” command :)
I did have a look at the code in the functions file but struggled to understand it enough to be able to figure out what was giving the problem I was experiencing.
Which functions?
The /src/initscripts/system/functions file from the git repo that has the loadproc, statusproc and killproc functions in it.
Regards,
Adolf.
I am glad that has been sorted and the initscript tidied up in line with IPFire coding style.
That is why we are all working together...
Will try and remember that in future.
If not, we are here to help :)

Regards, Adolf.

As wsdd is a python3 script, when it is run as a daemon the pidof command does not find any pid for wsdd. So a directory/file for a pid file was created. This is then passed to the loadproc and killproc commands. After the loadproc command has been created the pid is extracted from the ps aux command and put into the pid file. This then works when running the killproc command for it to know what to go and stop. The statusproc command does not have the ability to feed in the pid from a pid file and so it fails to find a running wsdd as it uses the pidof command. Code was added to the status section of the initscript to check if the pid file exists and if so to print the same command as used with the statusproc command, and also the same wording if the pid file does not exist because wsdd is not running. - info from the ethernet/settings file is used to identify if only green0 is available or if blue0 is also used and based on this the appropriate interface commands are added to the wsdd command. - wsdd is also set up to run in a chroot - Has been tested on my vm testbed, initially by editing the files on the vm clone. After everything confiremd to be working, the build was successfully carried out and the .ipfire package was copied to a new vm clone installed and shown to perform as expected. This test only confirms that wsdd is correctly installed and started. Shutsdown and restarts on reboot successfully. Confirmed from the ps aux info that wsdd has been started with the correct options. Thge testing can not evaluate if wsdd enables windows systems newer than version 7 top be able to detect the samba shares as I have no windows systems.
