>Description:
SunOS 5.x "rusers" client(supported rusers protocol 2-3) can communicate with SunOS 4.x(supported 1-2) and OpenBSD(supported 1-3).
But can't communicate with FreeBSD, Linux and other platforms(supported 1-2).

>How-To-Repeat:

>Fix:
I think Sun RPC rusers protocol 2 implementation is different others implementation in detail.
But, I don't know which is bad implementaion.

To Fix this problem, replace OpenBSD 2.0's RPC.
But it's dangerous to merge source-tree, I made rusersd replacement package from OpenBSD 2.0.
