Permissions
Server for NFS uses discretionary access control lists (DACLs) to simulate typical
UNIX and NFS permissions. The default permissions are read/write for all users.
To set permissions, perform the following steps in Windows Explorer:
1. Click Properties for the folder you are sharing.
2. Click NFS Sharing.
3. Click Permissions.
4. Set the permissions.
NOTE: UNIX and Windows 2000 security models have inherently different permission
sets. Any attempt to align them is only an approximation. For example, the “Take
Ownership” permission does not exist in UNIX, but in UNIX the superuser can change
the ownership of any file to any user.
UNIX Utilities
UNIX utilities provided with SFU are listed in below.
Telnet Server
The telnet server works optimally for most installations. It will accept logins from a
variety of clients, including the telnet clients shipped with Windows 2000,
Windows NT, Windows 95, and Windows 98, as well as a variety of character mode
terminal clients from virtually any operating system. In addition, it can be configured
to meet specific site requirements such as improving security, simplifying logins, and
supporting stream or console mode.
