crond: (*system*) BAD FILE MODE Error and Solution

Posted on in Categories , last updated March 15, 2010

I‘m getting this message in my /var/log/cron

Mar 12 09:20:01 server2 crond[1267]: (*system*) BAD FILE MODE (/etc/cron.d/vnstat)

How do I fix this problem under Fedora / CentO / RHEL or any Linux distro?

Run an ls -l on /etc/cron.d/vnstat file and find out the permissions. cron do not like files with world writable file and it is pretty picky about it. All you have to do it set 0644 (rw-r–r) permission i.e. remove world writable file permissions. Type the following command as root user:
# ls -l /etc/cron.d/vnstat
# chmod 0644 /etc/cron.d/vnstat
# ls -l /etc/cron.d/vnstat

This should fix the problem.

  1. This is not the fix.
    it doesnot help if your vnstat cron file is being generated every minutes and your umask setting is not 022 .
    What if i have umask as 002 and by vnstat file is being written every min by some other process.
