Mystery messages from cron
Okay, on one of my machines I've the following cron job:
* * * * * root /pressure/pressureget > /dev/null 2>&1
(as an aside, it's a program that queries a pressure transducer on
a serial port and dumps it's info to a file, but that's not important here)
Every once and a while we get some net flakiness, and when this
happens, I get email from cron on that machine:
From: root@me.umn.edu (Cron Daemon)
To: root@me.umn.edu
Subject: Cron <root@webster> /pressure/pressureget > /dev/null 2>&1
Date: Thu, 20 May 1999 00:00:02 -0500
do_ypcall: clnt_call: RPC: Unable to receive; errno = Connection refused
The problem is, where is this coming from? The both stdout and stderr
from /pressure/pressureget are thrown away, so where is this message
coming from?
