UNIX for Dummies Questions & Answers

This is my first posting. I am not a very sophisticated UNIX user.

I am trying to have an existing control string trigger another process at 4:00 p.m. My command looks like this on System V.4 UNIX.

at -f /scriptname 16:00

I have added the users to /etc/cron.d/at.allow and at.deny is empty. The message that appears is "cannot create a job for you". If I log on as super user this works, but it gives another message about "WARNING: This job may not be executed at the proper time".

I'm assuming my users are not authorized to create such jobs, but I don't know where to go to enable them to do this.

Thank you for any help you can provide.

Do a ls -l on /usr/bin/at

It should be suid to root. I'll bet that it's not. Put a user in at.deny...do you still get the same error for that user?

Also (as a test) remove the at.allow file - according to the man page for at

If only at.deny exists and is empty, global usage is permitted.

I did the ls -l it is rwxrwxrwx and the owner is root (group is sys). I also removed the at.allow and it still came back with the same message "cannot create a job for you". I will keep looking. Thanks for the input.

Someone did a
chmod 777 /usr/bin/at
and broke your at command. Repair it with:
chmod 4755 /usr/bin/at

Thank you! I think the chmod 4755 may have been the key.
