Description Pekka Savola 2000-10-12 21:00:40 UTC
If  /var/arpwatch/arp.dat is missing, arpwatch will die with a 
success error code (init.d/arpwatch starts shows OK).

Either arp.dat should be created in the RPM, arpwatch made to create it if necessary
or die in a more graceful manner.  E.g.:

Oct 12 23:58:27 haukka arpwatch: fopen(arp.dat): No such file or directory
Oct 12 23:58:27 haukka kernel: eth0: Promiscuous mode enabled.
Oct 12 23:58:27 haukka kernel: device eth0 entered promiscuous mode
Oct 12 23:58:27 haukka kernel: device eth0 left promiscuous mode

Comment 1 Jeff Johnson 2000-10-15 23:47:25 UTC
Here's what's in the tcpdump spec file (for the arpwatch sub-package)
	%config %{_vararpwatch}/arp.dat
and here's what's in the arpwatch package itself
	-rw-r--r--    1 root    root                0 Oct 12 10:04

Dunno what else needs to be done.

sometimes, arp.dat get deleted.
You need to touch it and change the user to pcap, in RH9, do this:
  # touch /var/arpwatch/arp.dat
  # chown pcap.pcap /var/arpwatch/arp.dat
the file arp.dat is included in the arpwatch rpm
