utmp files

Hi All,
if someone know where I can set dimension of utmp log files like
wtmp
failedlogin
sulog in an AIX system.
These are called security logs and they can reach a max amount in day or MB, where can I steady their size ?

thanks in advance.

you can limit the size of these files to a fixed number of lines with a shell script if thats an option for you

Code:
LINECOUNT=whatever you want

tail - "$LINECOUNT" /var/adm/wtmp > /tmp/wtmp.tmp
/tmp/wtmp.tmp > /var/adm/wtmp
rm /tmp/wtmp.tmp

(test before use, haven't done so yet, but should work ^^)

put this in a file and run in crontab every hour or whenever
