Non-Dce Client Api Configuration; Configuration Files - IBM Hub/Switch Installation Manual

The HPSS_REGISTRY_SITE_NAME environment variable is used to specify the name of the
security registry used when inserting security information into connection binding handles. This is
only needed when the client must support DFS in a cross-cell environment. The default registry is
"/.../dce.clearlake.ibm.com".
The HPSS_DMAP_WRITE_UPDATES environment variable is used control the frequency of
cache invalidates that are issued to the DMAPI file system while writing to a file that is mirror in
HPSS. The default value is 20.
The HPSS_GKTOTAL_DELAY environment variable is used to control the total number of
seconds to continue retrying a Gatekeeper request before the request times out. A value of zero
indicates that there is not time limit. The default value is 600.
The HPSS_LIMITED_RETRIES environment variable is used to control the number of retry
attempts before a limited retry error operation fails. The default value is 1.
The HPSS_DISABLE_CROSS_CELL environment variable is used to control cross-cell traversal.
When cross-cell traversal is disabled, a client will not be allowed to access directories which are
located in another DCE cell. The default value is zero (cross-cell enabled).
The HPSS_DISABLE_JUNCTIONS environment variable is used to control junction traversal.
When junction traversal is disabled, a client will not be allowed to access directories which require
traversal to the directory via a junction. The default value is zero (junction traversal enabled).
7.2 Non-DCE Client API Configuration
7.2.1 Configuration Files
The following files are required by the Non-DCE Client API to perform the authentication functions
correctly under the specified circumstances.
ndcl.keyconfig: This file is required on the client machine in order to use the DCE authentication
mode. It contains the encryption key used to encrypt the DCE principal and the password (which
are then shipped across to the Non DCE Gateway). By default this file is in the /var/hpss/etc
directory
The keyfile must contain the same key as the Non DCE Gateway Server Specific Configuration
screen in SSM. You must perform the following steps to set up the keyfile.
• Login on the client machine (the one running the Non DCE Client API) as user hpss.
• cd /var/hpss/etc
• Open the Non-DCE Gateway Server Specific Configuration screen in SSM.
• Use vi or your text editor of choice to create and open ndcl.keyconfig
• Copy the key from the NDCG SSM screen to the keyfile in the following format:
"0x[first 8 digits] 0x[next 8 digits]"
