problem with rcp and rsh !
 

I use ssh to login a remote machine and then use su to get it's root permission .
then . I want to try these order: rcp and rsh
I have read man before use them.

[root@localhost etc]# rcp vnc-3.3.3r2-28.2.i386.rpm 192.100.100.2:/tmp/vnc-3.3.3r2-28.2.i386.rpm
Permission denied

192.100.100.2 is the remote computer

I don't know if I using it right .

and the reply of rsh is the same .
[root@localhost etc]# rsh 192.100.100.2 ls /home/down
Permission denied

who can tell me where the problem occured ??
thanks in advance!

why arnt you using scp? I mean you take the trouble to log in securely *then* use a COMPLETELY unsecure copy method? Tell you what: use SCP and if you still have probs with that, then come back.
