VUE actions defined to run on a remote host use the "SPC"
remote execution system to start remote processes. During
authentication, SPC creates a temporary file in a directory to verify
the user's identity on both systems.
In order for authentication to succeed, the authentication directory
must exist, and must be accessible with read/write access by all users
on both machines involved in any remote execution requests. The client
host must mount the authentication directory. This may be a hard mount,
or the mount may occur automatically through the -hosts automounter map.
The SPC authentication directory is configurable and by default, the
following directory on the remote execution host is used:
- HP-UX 9.0
/tmp
- HP-UX 10.0
/var/tmp
However, because HP-UX 10.0 diskless clients cannot export a file system
to use for SPC authentication, a file system on another host must be
used. To specify the alternative directory, SPC supports the use of a
sharedtmpdir file that contains the authentication directory to be
used. Although any directory on the network may be used, the
recommended directory is /var/tmp on the diskless client's server.
Once the directory is selected, the directory path should be placed in
the following file:
- HP-UX 9.0
/usr/softbench/config/sharedtmpdir
- HP-UX 10.0
/etc/bms/config/sharedtmpdir
For example, if directory /var/tmp on host dserver is selected and
/net is the NFS mount point, the sharedtmpdir file on the diskless
client would contain the following line:
Keep the following in mind when establishing network links on diskless
clients:
The host on which the authentication directory resides must export the authentication directory to all hosts using the SPC service on the diskless client host. In the previous example, this meant that dserver had to export the /var/tmp file.
All VUE and SoftBench client hosts must mount the authentication directory to use the SPC service on the diskless client host. In the previous example, this meant each client must mount dserver's /var/tmp.
On HP-UX 10.0, if the Softbench
/etc/opt/softbench/config/sharedtmpdir file is installed, the directory contained in this file will take precedence over the directory in /etc/bms/config/sharedtmpdir.
Operation of sharedtmpdir is unreliable if it is mounted through an automounter map other than -hosts.
