Permissions changing from 755 to 750

[rebouy]

Hi we are having a related issue in a couple servers.

In one server a subdomain's root folder is changing permissions from 755 to 750 apparently on its own.
In another server (different client) an addon domain's root folder is doing the same.

This causes the sites to appear offline.

Any idea what could be causing this or in what way can i track it?

Hello,

Is there any cron set ? That's a possibility if no human interventions are being done!

Hi cPtechie,

Thanks for the reply.

There is no cronjob running. not at user level or server level (at least not ours) that would do chmod

If the machine is a dedicated not VPS, you could try installing auditd and using auditctl to track when the file is modified and by what:

Linux audit files to see who made changes to a file

This is a good guide on using auditctl to perform that task. It will not install on VPS systems many times, so the machine(s) must be non-VPS to add auditd to run auditctl checks on set files or folders.

Unless the VPS is run on a real HW virtualization platform like Vmware. Then you should be able to run this fine.

You can check /var/log/messages and /usr/local/cpanel/logs/access_logs if the change of permission was happened through ftpclient or file manger through cPanel.

From where are you changing the permissions? File Manager?

It could be possible that the folders are owned by a different account and hence in the file manager although it is showing you that the permissions have been changed, when you refresh, it is resetting the original permissions.
