Debian not updating arp cache

[Lindqvist Per <per.lindqvist@btj.se>]

Hi all,

I'm testing a cluster (non-debian) with IP address take-over. The cluster
machines send gratuitous arps when fail-over occur. I have tried different
OS on the LAN including Windows Server, Solaris, AIX, Cisco IOS, Extremeware
and they act correctly to the gratuitous arps; updating there arp table.

However, when I use debian woody (fresh install from CD) I have problem. It
won't update its arp table.

How can I get my debian to "listen" to gratuitous arps?

TIA,
Per Lindqvist
