	This is V1.82 for 2.10.1BSD, the only difference was one
	long vs. int change in rcp.c.

>Subject: V1.82 (Rcp/rdist security patch)
>Approved: ucb-fixes@okeeffe.berkeley.edu
>
>Subject: Rcp/rdist security patch
>Index: bin/rcp.c 4.3BSD
>Index: ucb/rdist/server.c 4.3BSD
>
>Description:
>	There's a security problem associated with rcp and rdist
>	in the 4.3BSD, 4.3BSD-tahoe, and first BSD networking
>	distributions.
>Fix:
>	Replace your current bin/rcp.c with the attached rcp.c.
>	Patch the server.c module in your current rdist with the
>	attached patched.  Recompile and re-install.
