Description Gleb Smirnoff 2003-07-17 12:30:19 UTC 
	  arpwatch.sh is not part of arpwatch 2.1.a11, but a part of its
	FreeBSD port. arpwatch.sh is installed into /usr/local/etc/rc.d
	and starts arpwatch at boot time.
	  It runs as many arpwatches as specified by variable
	${arpwatch_interfaces} in rc.conf. 
	  The problem is that all this arpwatch processes try to use 
	the same /usr/local/arpwatch/arp.dat. At shutdown time there 
	exists a race condition between them: each arpwatch process dumps
	his data into arp.dat, and there remains table of the last
	exited one.

Fix: Let each arpwatch use his own arp.${iface}.dat:
How-To-Repeat: 	Set ${arpwatch_interfaces} to a list of interfaces, more than 1.
	Run arpwatch, look at your mail, write down 'new stations'. 
	killall arpwatches, start arpwatch.sh again. Look at your mail.
	Some 'new stations' will appear again.
