Linux – Permissions on $HOME/.dmrc file

configurationlinux

I am learning Linux and recently encountered an error upon reboot saying "User's $HOME/.dmrc file is being ignored.." The message went on to say this was preventing the default session from being saved and that the file needed to have 644 permissions. I started some reading on permissions and config files and reinstalled Linux fresh on my VM. I also read various forums that advised users facing similar problems to chmod permissions for this file to 644. However, in the fresh install I see that the default permission for home/.dmrc is 600 (-rw——-). Why is this the case? If it needs to be 644, why would it be set to this on the default install.

0644 is world readable. Which means that any other user could potentially read your settings.

0600 is only readable by your user. There's no valid reason why a programm run by your user needs privileges more open than 0600 to function correctly.

Are you sure you aren't mixing the permissions up and it actually complains about being 644 rather than 600?

It sounds from your description that the cron job just needs to read the files, which it should be able to do. Is the issue that you're trying to uncompress the files in place? Can you uncompress them to a temporary folder instead?

check your apache configurations, usually in /etc/apache2/ or /etc/httpd/ or /etc/apache, and look through the configuration for the directive User, if User is numeric 2016, that's just how it is set up.

do you know if the server is running with SELinux or any 'non-standard' configurations going on on it?

you can also do ps aux | grep apache (or grep httpd, mileage may vary), to see the user/userid that the service is running as. for example:

www-data 14549  0.0  1.0  23340  9864 ?        S    May17   0:00 /usr/sbin/apache2 -k start

shows me www-data is the user running apache2 on my site.

let us know what you find out.
