    Hi all,

    I created a non-providledged user called sysinfo and put this in his
    crontab:

    34 * * * 1 /home/sysinfo/src/sysinfo/bin/sysinfo -class all | grep -v
    "sie\:" > /home/sysinfo/logs/sysinfo.`hostname`.`domainname`.`date
    +%d.%m.%y.%H\:%M\:%S` 2>&1

    The grep -v sie is to remove the error messages like these, which is fine
    since I don't need to run sysinfo as root:

    sie: WARNING: This program should be run as `root' (uid=0) to obtain all
    supported information. Please either make setuid to
    root (chown root sysinfo;chmod u+s sysinfo) or invoke as a uid=0 user such
    as `root'.
    sie: cannot open /dev/kmem

    The problem is that the cron fails. If I run this from the cli then the
    output is fine. Its only when I run this from cron if fails. The sysinfo
    accounts Email from cron reads:

    >From sysinfo Mon Jul 26 04:35:56 2004
    Date: Mon, 26 Jul 2004 04:35:56 -0400 (CLT)
    From: Sysinfo <sysinfo>
    To: sysinfo
    Subject: Output from "cron" command

    Your "cron" job on aguila
    /home/sysinfo/src/sysinfo/bin/sysinfo -class all | grep -v "sie\:" >
    /home/sysinfo/logs/sysinfo.`hostname`.`domainname`.`date +

    produced the following output:

    sie: WARNING: This program should be run as `root' (uid=0) to obtain
            all supported information. Please either make setuid to
            root (chown root sysinfo;chmod u+s sysinfo) or invoke as a
            uid=0 user such as `root'.
    sie: cannot open /dev/kmem
    sie: cannot open /dev/kmem
    sie: cannot open /dev/kmem
    sie: WARNING: This program should be run as `root' (uid=0) to obtain
            all supported information. Please either make setuid to
            root (chown root sysinfo;chmod u+s sysinfo) or invoke as a
            uid=0 user such as `root'.

    As a result nothing is sent to the log file via cron, but the log file is
    created when run from the CLI.

    Does anyone know why this job fails?

    Rdgs/Atentamente,
    Simon.
