Where do I find the /usr/bin/crontab permissions so I can change them to the 4755 that it wants? Also will I have to change these permissions in order for the cron to carry out my script?
We do not have access to that folder and cannot change permissions on it. The staff would have to do this for you, but I doubt they will. Having read access to system folders is a security risk. You may have to modify the script or find another way to do what you are trying to do.
