How to setup rsh (even though you should be using ssh)

Let me start out by saying, I do not advocate rsh as it is insecure, however; I will post this nonetheless to help those in dire straights.

Also, I don't guarantee this will work for you but it did for me. If this breaks your setup, I will not be held responsible. Look before you leap :)

1. Install these packages (either yum, apt-get, or rpm):
   

   xinetd
   rsh
   rsh-server



2. Now run this:
   

   echo "rsh" >> /etc/securetty
   echo "rlogin" >> /etc/securetty



3. In /etc/xinetd.d/rsh and /etc/xinetd.d/rlogin, change:
   

   disable = yes

   to
   

   disable = no



4. Add promiscuous to line in /etc/pam.d/rsh and /etc/pam.d/rlogin like so:
   

   auth       required     pam_rhosts_auth.so promiscuous



5. Start the daemon:
   

   /etc/init.d/xinetd.d start



6. For a passwordless login setup, add the target hosts name in the following file on the source host:
   

   /root/.rhosts
