file /tmp/last_uuid with perm 666 created

[Simon Jespersen]

Hi
I keep getting this file created with world writable permissions.

Search on itrc doesnt give me anything, when i google i can se that it is referes to the aserver, which should a daemon that keeps track on audio devices etc.. This deamon is not alive on my server.
Can anyone tell me what generates that file and how to prevent it being generased.
im running 11.11i on superdome npar partition.
best regdards Simon

Hi Simon:

I wouldn't be concerned, although I don't know the origin of the file, either. The '/tmp' directory is designed for holding temporary files for operating system processes. Correspondingly, '/var/tmp' is (or should be) used for temporary application files.

That said, you could try using 'fuser -c' or 'lsof' to determine what process may have the file in question open.

Regards!

Simon,
a starting point could be to look at the ownership of the file and when it is created/modified ?(ll)

Do you have a cronjobs at about that time ?
What is the file contents ?

Or you can change the ownership of the file and the permissions, so that the unknown application will fail next time it tries to use the file, giving (hopefully) some log entries !

Well, i have tried fuser -c, lsof, have have chekked that audio (Aserver) not running and not starting on boot. It is created by root:sys
-rw-rw-rw- 1 root sys 16 Nov 22 07:21 last_uuid

there is nothing in crontab, that explain it.
If i delete this file it will appear again. Im just wondering what it is and why it is there.
