Permissions help

Hello:

I am trying to finish migrating to a new SSD server, I also upgraded from Ubuntu 13.10 to 14.04, but I don't think that has anything to do with my issue.

I have some Perl scripts in folders under the /home/myusername

These scripts create images using imagemagick for weather, run via crontab as the user.

They write to folders under /var/www

I am having issues with some of of the folders, images are not being written. I am in the process of updating the scripts so they give me better feedback as to issues like this, but I am not quite there yet.

Everything is running fine on the old server, but I think in the process of setting the old server up, I changed the way I did permissions. I've tried to set file permissions the same for all the different folders, but still have an issue.

I do not log in as root.

On the new server I created a "webmasters" group, and my username is part of that group. I updated all the files in /var/www to reflect me as the owner and webmasters as the group.

I am at a loss, as I have been banging my head on this fore several days now.

I am not sure where else to check, as everything seems to have the same permissions from old server to new.

Maybe I am going about the permissions the wrong way, or maybe there is a better way?

If anyone has any suggestions, it would be greatly appreciated.

Thanks!

John
