tcp_wrapper and ftp server

[dawei @ hls . com (Dawei Yang)]

Hi, 

  I'm planning to set up a ftp server outside firewall by using
  tcp_wrapper.  This is to allow only internal user telnet or rsh
  to it but only ftp for outside users.  Is tcp_wrapper a good
  way of implementing this?

  Any suggestion, experience, and pointer are very much appreciated.

 
  Thanks,
  David
