Hi,

In a Unix Server when i 'su' to my name and type in crontab it says " You are not authorised......".

Pls suggest what to do? How do i give myself permission so that I can schedule a cron.

UNIX account with your name may not have permission to set crontab entries.

Following is transcript from manual pages of crontab. you could check /etc/cron.d/cron.allow or /etc/cron.d/cron.deny files

Users: Access to crontab is allowed:

o if the user's name appears in /etc/cron.d/cron.allow.

o if /etc/cron.d/cron.allow does not exist and the user's
name is not in /etc/cron.d/cron.deny.

Users: Access to crontab is denied:

o if /etc/cron.d/cron.allow exists and the user's name is
not in it.

o if /etc/cron.d/cron.allow does not exist and user's
name is in /etc/cron.d/cron.deny.

o if neither file exists, only a user with the
solaris.jobs.user authorization is allowed to submit a
job.

o if BSM audit is enabled, the user's shell is not
audited and the user is not the crontab owner. This can
occur if the user logs in by way of a program, such as
some versions of SSH, which does not set audit parame-
ters.

The rules for allow and deny apply to root only if the
allow/deny files exist.

Once you have "s-bit" (4755) for crontab command, then users will be able to make their own crontab simply with "crontab -e"
This will create file name "username" in /var/spool/cron directory
