[Q] create account which can only transfer file use SSH????

[mcclnx mcc]

We have Redhat AS 2.1 nad 3.0 installed on servers. 
Due to security reason, we disable FTP and TELNET. 
Server onlly support SSH.  

We plan to create a account which can ONLY login and
transfer data use scp or winscp on PC site (similiar
to FTP function).

Any one know how to set it up on Redhat?

Thanks.
