Autosys Event_Demon log file permission issue

[Anon Anon]

We are running Autosys 4.5 instance on Linux machine

We see that event_demon log has been created with incorrect permissions.

 

No read permission for the other(s)/group.

 

-rw-------

The above read/write is only for the persons logging as autosys ID

 

On normal cases, it should be:

 

-rw-r--r--

 

We are seeing this issue from recent times.

 

Kindly help.

I suspect this would be related to the umask setting for the user starting the event_demon.

 

For example, perhaps when you start as root you get 0600 but when you start using autosys (or some other) user you get 0644. Or vice versa.

Mark,

 

Thanks for your reply.

But our Autosys id is having 0002 as the umask value.

Also not for all instances we get this issue and we recently started seeing this in couple of instances.

Always the Autosys instance will be started under "Autosys" id only.

 

Do you know how can be prevent this?

 

Thanks in advance.

I assume you mean 0022 for your autosys id. Since this recently started, it suggests that something changed. Has the mount point changed at all? What does 'mount' reflect for the log location?

Hi Mark,

 

Thanks for your response.

umask value for Autosys ID is 0002 and not 0022 for the issue server.

We don't know if mount point has been changed. The file system is mounted on "Root" currently.

Another instance resolved on it own when it created a new file after 00:00 AM after a couple of days.

But still this is been a problem

[Mark_Hanson]

I did see some reports of similar behavior in some old 4.5.x cases. In a couple cases it occurred following an OS update.

In each case the problem resolved itself after a midnight rollover (as you described for one instance) or it was resolved following a restart at the next maintenance.

As a precaution, check your eventor script to make sure it has not been modified.

You should find the following lines within:

 

touch $outfile

chmod 644 $outfile

 

At the next EP restart ensure that the out directory and log files are at the expected permissions prior to restart.

Correct as needed.

Vignesh, did Mark's suggestion help you? Can you come back and let us know? Thanks!

Hi Lenn,

 

Just explained more about this with the umask value for our "Autosys" id

Also requested help on how can we prevent the issue and what's the solution

Hi Vignesh

A few more explanantions about umask setting

Default umask value for any Unix/Linux file is 666

I would suggest to set umask 022 in /etc/auto.profile which is normally executed by the autosys userid

By setting umask 022, permissions of the newly created files will be 644

 

0110 0110 0110

0000 0010 0010

---------------------

0110 0100 0100

6        4      4

 

Otherwise you can also trace the event_demon process with an strace command like: strace -f -o /tmp/event_demon.trace -p <PID of event_demon process>
