1) Welcome to the Party!
2) As you are obviously new here, I have some suggestions to help us all help you:
When you post, please post your entire configuration including (but not limited to) your installation method and vicidial version with build.
This IS a requirement for posting along with reading the stickies (at the top of each forum) and the manager's manual (available on EFLO.net, both free and paid versions)
You should also post: Asterisk version, telephony hardware (model number is helpful here), cluster information if you have one, and whether any other software is installed in the box. If your installation method is "from scratch" you must post your operating system and should also post the .iso version from which you installed your original operating system. If your installation is "Hosted" list the site name of the host.
If this is a "Cloud" or "Virtual" server, please note the technology involved along with the version of that techology (ie: VMware Server Version 2.0.2). If it is not, merely stating the Motherboard model # and CPU would be helpful.
Similar to This:
Vicibox X.X from .iso | Vicidial X.X.X-XXX Build XXXXXX-XXXX | Asterisk X.X.X | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation | Intel DG35EC | Core2Quad Q6600
3) Is the ssh service running? You did not disclose the error ... no response on port 22? Bad password? Have you considered firewall issues if there is no response?
4) After running those commands one time, there should not have been a need to run them again. Certainly not every minute forever. If new files were being generated in the MP3 folder with the wrong permissions, setting those new files to proper permissions is not related to setting the folders above them. Nothing should be changing those folders permissions.
5) Consider activating audio FTP scripts. This would push your audio files to an FTP server, which should be a whole new server. Properly configured that other server should also have HTTP available so the new locations of the files can be used to serve them instead of the Vicidial server. Then you have accomplished several things: If the Vicidial HD dies, you do not lose client audio. If the Vicidial system ever needs restoration, you do not need to "put those back" (which can grow to multiple terabytes, and take a freakin' long time and delay your restoration). When anyone plays an audio file, they do not add load to the Vicidial server. And for security purposes, you can allow access to recordings without allowing access to Vicidial.
