Allowing users to run the remote shell program (rsh) without a password (AIX® Linux®)
If you do not want to use a secure shell connection, you can choose instead to use rsh for each parallel engine connection. As with ssh, the connections must be able to be established without a password prompt.
About this task
You achieve rsh connections differently according to your
type of system. For example, you can edit the /etc/hosts.equiv
file
or create a .rhosts file for each user. In both
cases, add the host name of each parallel processing node to the /etc/hosts.equiv file
or the .rhosts file, specifying one host name
per line.
The host name that is included in this file must correspond to the setting of the node fastname parameter in the parallel configuration file, which is located in the /opt/IBM/InformationServer/Server/PXEngine directory by default.
