Hello,
I have found that arp produces no output if arp is in a script called
by a file in cron.d in Red Hat Linux 7.2 using /bin/bash.
1) arp from the command line produces the expected output
2) in a script
V1=`arp`; echo $V1 > out
produces the expected output in the file named "out"
3) the same script called by cron by placing a file in /etc/cron.d
produces no output in the file named "out"
4) if I substitute
cat /proc/net/arp
for arp then I get output from a script called from cron
My question is "Why does arp behave differently when in a script called
by cron?"
Thanks very much,
Jerry
