rcp across two networks

[Joe L Gangemi]

I am looking for help in trying to use rcp across two different networks
connected by a router.

For Example:

VAX--------network 1---------Sun 4/330----------network 2------Sun 4/330
                             Sys. A                            Sys. B

1)  Sys. A has two ethernet controllers used to brdige the networks.
2)  The VAX host file contains Sys. A and Sys. B
3)  Sys A. host file contains the VAX and Sys. B
4)  Sys B. host file contains the VAX and Sys. A
5)  Network 1 is not running yellow pages but network 2 is.
6)  Both networks are an ethernet link.

I can use rcp to copy a file from the VAX to Sys B, and vice versa,
without any problem.  However, I can not use rcp to copy a file from the
VAX to Sys. B or from Sys B to the VAX.

I have tried "rcp fn SysA!SysB:d1"
             "rcp fn SysA at SysB:d1"
             "rcp fn SysA.SysB:d1"

I would greatly appreciate any help on the subject.

Thanks
