rcp problem

I have two hosts -A & B
host A can rcp file to host B by root a/c
rcp abc.txt root@hostB:/tmp --> it is Ok

but can't rcp file to host B by other user

rcp abc.txt user@hostB:/tmp ,
Permission denied.

I have updated the hostB ~user/.rhosts

#vi ~user/.rhosts
+ +
hostB user

but still not work , could suggest what is the problem ?

but very strange , the user can rlogin from hostA to hostB , but can't
rcp , could suggest what is wrong ? thx
