[Beowulf] persistant kerberos rsh

[Pete]

Hi all,

I wonder if anyone can help me. I have just installed mpich-1.2.7 and all
seems to be working fine. I do have one small problem when I launch it with
more than one node it always tries to connect to other nodes using kerberos
rsh first, and fails, then successfully connects using plain rsh. Two
questions, 1) will this impact on performance and can it be live with and 2)
if it is a problem how can I persuade mpich to use the plain version of rsh
first time. I have removed the krb5.sh file from /etc/profile.d directory so
there is no kerberos path in my bash env when compiling and running, but
kerberos is very persistent. 
kerberos
thanks,


Pete
