IMHO, I think you need to restrict root access more. But that's just me. Smilie

Also, typically you don't need to use su - root. You can just type su - and this will fault to root, at least on HPUX. You only need to specify su - username for any other user besides root. Again this is my experience on HPUX. Smilie

Your answer is to alias su to su -, which you probably already figured out. You can overwrite a command by aliasing it. When you remove the alias the original command takes over again.

alias su=`su -`#syntax depends on OS version #those are backtics

NAME
cellalias - A dcecp task object that manages cell name aliases SYNOPSIS
cellalias catalog cellalias create cellalias_name [-force] cellalias help [operation | -verbose] cellalias operations ARGUMENTS
A single fully qualified alias name for the cell in the form: /.../cellalias_name The name of the cellalias operation for which to display help information. DESCRIPTION
The cellalias task object allows you to create and display alternative names for cells, known as cell aliases. You can create multiple aliases for a single cell, but only one per cellalias command. When you create an alias, cellalias does the following: Creates a new principal to represent the cell alias in the registry. Performs a registry verify operation to ensure that all security replicas in the cell are up to date. Creates the specified alias name in CDS using a cdsalias create operation. Performs a directory synchronize operation to ensure that all the CDS replicas are up to date. Performs some hostdata operations on each host in the cell for which you are creating the alias. Updates all dced objects and the dcelocal/dce_cf.db and dcelocal/etc/security/pe_site files to reflect the new alias name. (This action can take a long time to complete in a cell with many hosts.) OPERATIONS
cellalias catalog Returns a list of all cell alias names for the local cell. The syntax is as follows: cellalias catalog In the list of cell alias names, the cell's primary name (the name assigned when the cell principal was created) is listed first. The alias names are listed after the primary name. Privilege Required Requires r (read) permission on the root directory of the cell. Examples dcecp> cellalias catalog /.../gumby /.../pokey-alias dcecp> cellalias create Creates a new alias for the local cell. The syntax is as follows: cellalias create cellalias_name [-force] Options Ignores errors encountered during execution. The required cellalias_name is a single fully qualified name. You must start dced in remote-update mode with the -r option before you use cellalias create. This operation returns an empty string on success. Privilege Required Requires a (auth_info) permission on the root directory of the cell. Examples dcecp> cellalias create /.../green.cell.rainbow.com dcecp> cellalias help Returns help information about the cellalias task object and its operations. The syntax is as follows: cellalias help [operation | -ver- bose] Options Displays information about the cellalias task object. Used without an argument or option, the cellalias help command returns brief information about each cellalias operation. The optional operation argument is the name of an operation about which you want detailed information. Alternatively, you can use the -verbose option to display detailed information about the cellalias task object itself. Privilege Required No special privileges are needed to use the cellalias help command. Examples dcecp> cellalias help catalog Returns the cell alias names currently in use. create Creates a new alias name for the local cell. help Prints a summary of command-line options. operations Returns a list of the valid operations for this command. dcecp> cellalias operations Returns a list of the operations supported by the cellalias task object. The syntax is as follows: cellalias operations The list of available operations is in alphabetical order except for help and operations, which are listed last. Privileges Required No special privileges are needed to use the cellalias operations command. Examples dcecp> cellalias operations catalog create help operations dcecp> RELATED INFORMATION
Commands: dcecp(1m), dcecp_account(1m), dcecp_cdsalias(1m), dcecp_directory(1m), dcecp_hostdata(1m), dcecp_registry(1m). cellalias(1m)
