I have a problem with the /usr/libexec/save-entropy script executed by crontab in /etc/crontab :
> # Save some entropy so that /dev/random can re-seed on boot. > */11 * * * * operator /usr/libexec/save-entropy When I let the /etc/crontab script execute normally I have a mail generated automatically complaining about "--: not found" > & 1 > Message 1: > From [EMAIL PROTECTED] Sun Nov 2 23:11:00 2003 > Date: Sun, 2 Nov 2003 23:11:00 +0100 (CET) > From: [EMAIL PROTECTED] (Cron Daemon) > To: [EMAIL PROTECTED] > Subject: Cron <[EMAIL PROTECTED]> /usr/libexec/save-entropy > X-Cron-Env: <SHELL=/bin/sh> > X-Cron-Env: <PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin> > X-Cron-Env: <HOME=/> > X-Cron-Env: <LOGNAME=operator> > X-Cron-Env: <USER=operator> > X-Spam-Status: No, hits=0.8 required=5.0 > tests=CRON_ENV,FROM_AND_TO_SAME_5,SPAM_PHRASE_00_01 > version=2.43 > X-Spam-Level: > > --: not found I had to comment the line in /etc/crontab so that It stopped generating error every 11 minutes, could this be a potential problem ? I don't exactly see what seems to go wrong with the script !?
