Go to www.google.com.  Type rsh linux in the search box.  Click search. 
 Some relevant results:

I think that rsh and rlogin may use the telnet daemon on the remote host 
(though I'm not sure).  This is insecure.  You should use ssh instead.

Ping only tells you if the machine is up and returning ICMP requests. 
It's got nothing to do with whether the remote machine is running the 
daemon that you need.
