How can I figure out which process is changing the permissions of a file?
on a Debian server, I have the problem that something is changing the permissions on
/dev/null every day at 6:20 (since 3 weeks). When I set the correct permissions, they are set back between a few minutes. Then I set it again and after that permissions stay correct until next day 6:20. It doesn't matter at which time I set the permissions.
