Cron problem

[binumvk]

In my cpanel linux server everytime a user is trying to set a cron file.I try to block that
particular user to setting any cron job through cron.deny file,but cron.deny is not there (/etc/cron.deny)how can i block this particular user.

Just create the file yourself and put the users you want to deny one per line.

any cronjobs in crontab.If i delete that file all r going fine
