Are there any other scheduling apps I can try out for CentOS 5.2? as cron seems to be very picky about what it runs, and I cant see any reason why my script is having problems.

Ive even told the /sbin/ausearch the full path to the audit file incase it cant find it, using cron.
strace/truss the command and see if it's successfully opening your audit.log file.

Code:
strace -o /myLog.strace /sbin/ausearch -ua 500 -ts `date +%Y-%m-%d` -k tc-tocs -i

You should find something like:

Code:
open("/var/log/audit/audit.log", O_RDONLY) = 4
access("/var/log/audit/audit.log", R_OK) = 0

Also, try upgrading your audit and audit libs to the latest version to ensure that your ausearch is not under the effects of RH bug 436301.


From the ausearch manpage:

Code:
--input-logs
              Use the log file location from auditd.conf as input for searching. This is needed if you are using ausearch from a cron job.

NAME
autrace - a program similar to strace SYNOPSIS
autrace program [-r] [program-args]... DESCRIPTION
autrace is a program that will add the audit rules to trace a process similar to strace. It will then execute the program passing arguments to it. The resulting audit information will be in the audit logs if the audit daemon is running or syslog. This command deletes all audit rules prior to executing the target program and after executing it. As a safety precaution, it will not run unless all rules are deleted with auditctl prior to use. OPTIONS
-r Limit syscalls collected to ones needed for analyzing resource usage. This could help people doing threat modeling. This saves space in logs. EXAMPLES
The following illustrates a typical session: autrace /bin/ls /tmp ausearch --start recent -p 2442 -i and for resource usage mode: autrace -r /bin/ls ausearch --start recent -p 2450 --raw | aureport --file --summary ausearch --start recent -p 2450 --raw | aureport --host --summary SEE ALSO
