List good morning,
I do regret asking such a basic question about cron, but I cannot seem
to get rid of what I think is a mis-configured entry, somewhere.
We have a server running Lenny (still), its role is solely to provide
a network file system. Every 17 mins past the hour, root is sending
an email with this title:
Cron <root@server4> root cd / && run-parts --report /etc/cron.hourly
and content:
/bin/sh: root: command not found
In /etc/cron.d there are only files for anacron and mdadm; neither of
these have entries for every 17 mins past the hour.
In /etc/cron.hourly there is only an empty .placeholder file.
I've tried commenting out relevant entries in /etc/crontab, but
without effect. /etc/crontab contains:
# was executing 'root' so commented out; still error messages
# 17 * * * * cd / && run-parts --report /etc/cron.hourly
and, as a last resort a couple of days ago:
# disabled because of multiple error messages in email but no effect
# 17 * * * * root cd / && run-parts --report /etc/cron.hourly
Hourly email messages still occur. I would guess this second crontab
entry was - in practice - ok, and perhaps I should re-enable it for
system purposes, anyway.
I checked /etc/anacrontab in case it could be involved, it seems not
to contain any cron.hourly entries, nor entries at the relevant time:
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# These replace cron's entries
1 5 cron.daily nice run-parts --report /etc/cron.daily
7 10 cron.weekly nice run-parts --report /etc/cron.weekly
@monthly 15 cron.monthly nice run-parts --report
/etc/cron.monthly
I'm missing some aspect of cron configuration, or perhaps some other
cron file somewhere. root doesn't have a /home directory, so there
isn't a crontab in it, and the only user existing on the system
doesn't have a crontab in its home directory, either.
I enjoy mysteries. This one is beginning to frustrate, though. I've
misunderstood something about cron, but what is it?
regards, Ron
