SPC Security

Authentication for the subprocess control service is based on file system authentication. The dtspcd must have access to an authentication directory that is also mounted by all SPC client systems.

By default the dtspcd authentication directory is the user's home directory. However, you can configure the dtspcd to use a different location by setting the -auth_dir option in the /etc/inetd.conf directory. See the dtspcd(1M) man page for more information.

Because SPC authentication is based on file system authentication, the SPC service is only as secure as your distributed file system. If you are using the desktop in a network where you do not trust the distributed file system, you may wish to disable the dtspcd. To disable the dtspcd, comment out the dtspc entry in /etc/services.
