Hi,

I am trying to run Configuration File and get following Error.

It runs 5 processes on 4 nodes.
Host key verification failed.
Host key verification failed.
Host key verification failed.
##W IIS-DSEE-TFPM-00152 20:17:56(000) <main_program> Accept timed out retries = 16
##E IIS-DSEE-TFPM-00153 20:17:56(001) <main_program> The section leader on CNDABMCSDBDT03 died
##E IIS-DSEE-TFPM-00356 20:17:56(002) <main_program>

and Following is My Configuration File -

{
node "node1"
{
fastname "CNDAMBCSDBDT04"
pools ""
resource disk "/datafs6/Datasets" {pools ""}
resource scratchdisk "/datafs6/Scratch" {pools ""}
}
node "db2node1"
{
fastname "CNDABMCSDBDT03"
pools "db2"
resource disk "/datafs6/temp" {pools ""}
resource scratchdisk "/datafs6/temp" {pools ""}
}
node "db2node2"
{
fastname "CNDABMCSDBDT03"
pools "db2"
resource disk "/datafs6/temp" {pools ""}
resource scratchdisk "/datafs6/temp" {pools ""}

node "db2node3"
{
fastname "CNDABMCSDBDT03"
pools "db2"

See:

"Host key verification failed.
Host key verification failed.
Host key verification failed."

It's an issue of permissions across from the node you are running from, in connecting to the node defined which it is showing in error.

I have checked node file and got permisstions are correct.

Not permission on the node file, but permissions to the nodes referenced by the file (the fastnames).

I have checked permission of node file. all that things are ok.

Have you checked that the keys for rsh have properly been emplaced?

That's not what Arnd, Ray and I have been pointing out. It's permissions between the nodes, which means it is an issue of "one server (not) being able to access another", in plain English. It seems to me you would be best speaking to your unix administrator.

Read the man page for rsh and learn about the different ways that the remote host will allow access. One of these authentication things must be done in order for rsh to work (and therefore for multi-machine parallel jobs, which rely upon rsh, to work).
