Telnet port.
Console or Stream for mode of operation.
Default Domain Name is the domain name that is automatically added to the login username. The default is
".", which disables this feature.
Idle Session Timeout is the time until an idle session is forcibly disconnected.
Terminate all programs when disconnecting or Continue to run programs started with the command
bgjob.
Sessions allows you to see data about the currently active sessions (such as user, domain, system, and logon
date/time) and to either send a message to the session or terminate it.
Services for UNIX MMC Console
SFU includes a single MMC for managing all of SFU. The MMC provides a cohesive management interface that allows you to
administer all systems on the network from any console. Further, since SFU supports the WMI, management can be scripted
from the command line.
You can access the MMC Console by selecting Computer Management under System Management on the Advanced
Administration Menu. See " Using the PowerVault Advanced Administration Menu " in "NAS Manager."
ActiveState ActivePerl 5.6
SFU includes ActiveState's ActivePerl 5.6, a full-featured port of Perl 5.6 and Perl Script to Windows Powered operating
systems. Among other improvements, ActivePerl 5.6 includes support for fork() emulation at the interpreter level, improving
the portability of scripts and modules. ActivePerl also provides full support for the Windows Script Host, making ActivePerl an
excellent tool for system administration tasks.
User Name Mapping
User Name Mapping provides mapping of names between the UNIX and Windows environments. You can configure User Name
Mapping from the SFU MMC Console or by using the NAS Manager to configure properties for the NFS Sharing Protocol. With
User Name Mapping, you can create simple maps between Windows Powered user accounts and corresponding UNIX
accounts. You can also use the Advanced Map feature to map accounts with dissimilar names. Because UNIX user names are
case-sensitive, and Windows Powered operating system names are not, the use of User Name Mapping can greatly simplify
maintaining and managing accounts in the two environments. User Name Mapping uses Network Information Service (NIS) or
local Personal Computer Network File System (PCNFS) user and group files to authenticate users. Also, User Name Mapping
supports bidirectional one-to-many mapping, allowing you to map a single UNIX or Windows Powered operating system
account to multiple accounts in the other environment. For example, you can map more than one administrative account in a
Windows Powered operating system to the UNIX root account.
Special Mappings
By default, the root user for the UNIX client is mapped to an unmapped user. This setting is commonly known as "root
squashing." When an NFS authentication request is made for a user name mapped to an unmapped user, the result is an
anonymous UID and GID (typically -2 and -1, respectively). Any files created by such a user will show file ownership as an
anonymous Windows user.
NOTE: To prevent SFU from performing root squashing for specific NFS shares, the UNIX root user and group must be
mapped to the Windows administrator user and group. The "access type" for the NFS share's permissions must also be
set to root for each applicable client or client group.
To create user and group name maps, perform the following steps:
1. Log in to the NAS Manager.
