Missing Cron?

[PeterT]

Every night at 5:30 CronD emails me with the following:

"/bin/sh: line 1: root: command not found
Null message body; hope that's ok"

Subject:

root /usr/local/bin/rkhunter --checkall --nocolors --cronjob --report-mode --createlogfile --skip-keypress > rklog.txt | grep -v "[OK]" rklog.txt > rk-clean.txt | grep -v "Clean" rk-clean.txt | mail -s "RKHunter check" email@domain.com

The best part of this is that I can't find the responsible cronjob nor can I remember ever setting it

I've checked:

/var/spool/cron.*
/var/log/cron.*
/etc/crontab
/etc/cron.*

but can't find anything...
crontab -l doesn't show anything either
Anyone have an idea?
The box is running FC2

It looks like you have Rootkit Hunter installed. This does not come with Fedora, so you must have installed it.

You checked all the /etc/cron.* directories, including cron.d? I would assume it would add some script like rkhunter.

crontab -e - it may have installed a cronjob in root's private crontab file

Indeed, but didn't install the cronjob...
Checked those directories - nothing.

and crackers, same story there

I'd guess it's time to dig into the installation itself and see where the thing may have come from...
