problems with rsh

Hello Everybody,

I have a set of four machines. When i try to rsh between them i get errors like 'no route to host' and 'conection refused'. What do i need to do to rectify this problem..... i can ssh between the nodes ok but only if i supply a password.

Here is the output from my screen:

hp64linux20:/home/RKapur>rsh hp64linux21
hp64linux21: Connection refused
hp64linux20:/home/RKapur>rsh hp64linux22
hp64linux22: No route to host
hp64linux20:/home/RKapur>rsh hp64linux23
hp64linux23: No route to host
hp64linux20:/home/RKapur>ssh hp64linux21
Warning: No xauth data; .
hp64linux21:/home/RKapur>rsh hp64linux20
hp64linux20: Connection refused
hp64linux21:/home/RKapur>rsh hp64linux21
hp64linux21: Connection refused
hp64linux21:/home/RKapur>rsh hp64linux22
hp64linux22: No route to host
hp64linux21:/home/RKapur>rsh hp64linux23
hp64linux23: No route to host
hp64linux21:/home/RKapur>


Your help would be appreciated.

Many thanks

Rkap

First off, you need to test in a more logical way (which you may have done but it isn't posted as such).

From hp64linux20 - rsh to hp4linux21 - then ssh to 21. Show the results.
Do the same for each system.

Second, it doesn't make sense that you can ssh but not rsh and you get a "No route to host" - the route would have to be there if ssh worked.

Third, "Connection refused" means rsh isn't allowed - turned off due to security reasons - stick with ssh.
