Description:

The ARP daemon moves the management of the ARP (Address Resolution
Protocol) table from kernel to user space. It is useful for sites with
LARGE network segments (256+ systems per segment), because the kernel
hash tables are not optimized to handle this situation. To use the ARP
daemon your kernel needs to have ARPD and NETLINK support enabled. The
standard kernels of PLD lack this support. It shouldn't be run without
that! This version can alocate 4096 entries.
