Make sure of the following:
You have standard NFS or direct access to the PKGs from the system dependency server machine. The CD is in the CD-ROM of the SDS machine; or the SDS has direct access to Solaris files. This procedure does not support FTP or HTTP.
Directories and files to be uploaded are readable by the nobody user.
If the software is in PKG format, expand the PKGs. Each creates a directory (and possible sub-directories) and places there the files of the package.
