arpalert: [./capture.c 232] pcap_open_live error: eth0: That device is not up

[Fernando]

Binary package hint: arpalert

I have this error in arpalert:
arpalert: [./capture.c 232] pcap_open_live error: eth0: That device is not up

Well, it seems that arpalert starts BEFORE the eth0 is completely up, so i decided to add the following in /etc/network/if-up.d:
-rw-r--r-- 1 root root 29 2009-09-03 15:08 resetear-arpalert

$cat resetear-arpalert
#! /bin/sh
/etc/init.d/arpalert restart
exit 0

And it works OK!

I've also renamed the arpalert init script to: /etc/rc2.d/S99arpalert (S99)

But in /var/log/daemon.log i still have:
