[mvapich-discuss] Re: rsh problem (fwd)

Hi Tai,

 | Hi,
 |    I have a problem when running mvapich-0.9.9, I built mvapich using the TCP interface. When compiling using mpif90 I have no problem but when I try to run it with 4 processors I encounter an error message.

 |     Trying krb4 rsh...
 |     krb_sendauth failed: You have no tickets cached
 |     trying normal rsh (/usr/bin/rsh)
 |     localhost.localdomain: Connection refused

This looks like a problem with rsh setup. Can you check if password-less
rsh works? 

If it doesn't, you might want to try the steps mentioned at
