Cron.php giving errors

I have setup OsTicket using fantastico on my webhost

I have setup a cron process but cron.php fails on

public_html/CRM/api/cron.php: line 1: ?php: No such file or directory

public_html/CRM/api/cron.php: line 2: /aquota.user: Permission denied

public_html/CRM/api/cron.php: line 3: cron.php: command not found

public_html/CRM/api/cron.php: line 5: syntax error near unexpected token `('

public_html/CRM/api/cron.php: line 5: ` File to handle cron job calls (local and

remote).'

Did i miss any configuration
