Problems with rcp command

I have two servers A and B; A has redhat 5 and B has Suse10. Both of them has rhost file configuration. When i try to copy file from A to B that is OK but when try to copy from B to A i have an error: connection refused.
I installed rsh and rsh-server on server A and stop iptables service.
I need to use rcp only.
Please send me some help

NAME

       rcp - remote file copy

SYNOPSIS

       rcp [-p] [-x] [-k realm ] [-c ccachefile] [-C configfile] [-D port] [-N] [-PN | -PO] file1 file2

       rcp [-p] [-x] [-k realm] [-r] [-D port] [-N] [-PN | -PO] file ... directory

       rcp [-f | -t] ...

DESCRIPTION

       Rcp  copies  files  between  machines.  Each file or directory argument is either a remote file name of the form ``rhost:path'', or a local
       file name (containing no `:' characters, or a `/' before any `:'s).

       By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file modified by the umask(2)
       on the destination host is used.

       If path is not a full path name, it is interpreted relative to your login directory on rhost.  A path on a remote host may be quoted (using
       , ", or ') so that the metacharacters are interpreted remotely.

       Rcp does not prompt for passwords; it uses Kerberos authentication when connecting to rhost.  Each user may have  a  private  authorization
       list  in  a  file  .k5login  in	his  login directory.  Each line in this file should contain a Kerberos principal name of the form princi-
       pal/instance@realm.  If there is a ~/.k5login file, then access is granted to the account if and only if the originater user  is  authenti-
       cated  to one of the principals named in the ~/.k5login file.  Otherwise, the originating user will be granted access to the account if and
       only if the authenticated principal name of the user can be mapped to the local account name using the aname -> lname  mapping  rules  (see
       krb5_anadd(8) for more details).

OPTIONS

       -p     attempt to preserve (duplicate) the modification times and modes of the source files in the copies, ignoring the umask.

       -x     encrypt all information transferring between hosts.

       -k realm
	      obtain tickets for the remote host in realm instead of the remote host's realm as determined by krb_realmofhost(3).

       -c ccachefile
	      change the default credentials cache file to ccachefile

       -r     if any of the source files are directories, copy each subtree rooted at that name; in this case the destination must be a directory.

       -PN

       -PO    Explicitly  request  new	or old version of the Kerberos ``rcmd'' protocol.  The new protocol avoids many security problems found in
	      the old one, but is not interoperable with older servers.  (An "input/output error" and a  closed  connection  is  the  most  likely
	      result of attempting this combination.)  If neither option is specified, some simple heuristics are used to guess which to try.

       -D port
	      connect to port port on the remote machine.

       -N     use a network connection, even when copying files on the local machine (used for testing purposes).

       -f -t  These  options are for internal use only.  They tell the remotely-running rcp process (started via the Kerberos remote shell daemon)
	      which direction files are being sent.  These options should not be used by the user.  In particular,  -f	does  not  mean  that  the
	      user's Kerberos ticket should be forwarded!

       Rcp  handles  third  party  copies,  where  neither  source  nor target files are on the current machine.  Hostnames may also take the form
       ``rname@rhost'' to use rname rather than the current user name on the remote host.

FILES

       ~/.k5login  (on remote host) - file containing Kerberos principals that are allowed access.

SEE ALSO

       cp(1), ftp(1), rsh(1), rlogin(1), kerberos(3), krb_getrealm(3), kshd(8), rcp(1) [UCB version]

BUGS

       Rcp doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal.

       Rcp is confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host.

       Kerberos is only used for the first connection of a third-party copy; the second connection uses the standard Berkeley rcp protocol.
