Coping filies from Linux Server to HP-UX Server

I intend to copy file from a linux server (named zambezi) to a hp-ux (named mocuba).
When I execute the command #rcp -rp zambezi:/etc/hosts /u2 /
I receive the following message
rcmd: connect: zambezi: Connection refused
when I execute the command in the linux to copy from the HP-UX I obtain the following message
remshd: Login incorrect.
I ask for help

Regards

You will get this if the service isn't allowed.

The account you used - wrong password or possible that root account wasn't allowed to login that way (but that may not get this error but another)

You must have both hosts in the other box's ~/.rhosts file for root or for the user that you have on both boxes.

zambezi root # in mocuba's .rhosts file
mocuba root # in zambezi .rhosts file

Use the full domain path if they are on different domains.

You must have user equivalency on both boxes to use rcp...
