NLMs, UNIX system permissions and NetWare rights

Without NUC and NFS NLMs, SCO Gateway for NetWare filesystems have DOS filename restrictions, as well as Novell permission semantics. Almost no information is provided to SCO Gateway for NetWare for incorporation into the UNIX system permission information. See ``Troubleshooting SCO Gateway for NetWare filesystems without NUC and NFS NLMs''.

With NLMs, SCO Gateway for NetWare filesystems have UNIX system filename capabilities. As well, Novell permission semantics are translated into UNIX system permission semantics. Note that NetWare has more file and directory permissions than does the UNIX system. Many NetWare permissions do not map directly to the UNIX system permissions. The major permission relationships are:

Table 3-1 UNIX and NetWare file permission relationships

 ----------------------------------------------------
 UNIX      NetWare
 ----------------------------------------------------
 read      read and file scan
 write     write, create, modify, erase and file scan
 execute   read, file scan

Table 3-2 UNIX and NetWare directory permission relationships

 ---------------------------------------------------
 UNIX      NetWare
 ---------------------------------------------------
 read      read and file scan
 write     write, create, erase and modify
 execute   file scan

Also note:

• To use the UNIX system chmod(C) command on a file in the SCO Gateway for NetWare filesystem, the owner of a file must have the NetWare Access Control right. Although this is the default condition for the SCO Gateway for NetWare filesystem, NetWare file rights can be altered by the NetWare administrator.

• To view NetWare file and directory access rights, use the filer command on a DOS client.
