Passwords on UNIX Managed Nodes
The ITO default operator opc_op cannot login into the system via login,
telnet, etc. due to a * entry in the /etc/passwd file. Furthermore,
.rhosts entries are not provided. If you want to provide a virtual
terminal or application startup (requiring a Window (Input/Output)
for the ITO default operator, set the password or provide .rhosts or
/etc/hosts.equiv functionality. Note that the opc_op's password
should be consistent for all managed nodes.
For example, the $HOME/.rhosts entry, where $HOME is the home
directory on the managed node, of the executing user:
<management_server> opc_op
