Default exported and shared directories

Default directories created

When setup finishes, two default directories are made available for access by clients. The default directories are

Permissions for the default directories

The following table shows the permissions that are assigned to the default directories when setup finishes.

This directory... From this client... Has these permissions...
The root directory NFS
  • full permissions for the root user on the administration host
  • no permissions for any other user or host
  • no permissions
CIFS
  • read and write permissions to all files for the Administrator user when logged in to the filer using the root password
  • no permissions for other users
The /home directory NFS permissions associated with individual users and with groups through UNIX security database
CIFS permissions assigned by the filer administrator for the HOME$ share

Accessing the directories

The following table shows how to access the default directories. Replace filer with the host name of your filer.

To access... From this client... Do this...
The root directory NFS Mount /filer/vol/vol0.
CIFS Map a drive to \\filer\C$.
The /home directory NFS Mount /filer/vol/vol0/home.
CIFS Map a drive to \\filer\HOME$. Or Use the Network Neighborhood icon to locate the filer and locate the HOME$ share.

Contents of the etc directory

The root directory contains an etc directory in which the filer configuration files are stored. You can modify the configuration files from the administration host.

The following table describes the files in the etc directory. Note that some of the configuration files might not exist on your filer if you use the filer for CIFS or NFS only.

File name Contents File-sharing protocol
.cifs.cat Domain information (only if the filer is a member of a domain) CIFS only
cifsconfig.txt CIFS commands that the filer used for configuration The filer maintains this file automatically whenever you enter a cifs command, which can cause changes you make manually to be lost. To edit this file, terminate CIFS service by using the cifs terminate command, edit and save the file, then reboot the filer. CIFS only
exports NFS export points NFS only
hosts Known hosts and their IP addresses All
hosts.equiv Trusted hosts and users for rsh All
group CIFS group names, GIDs (group identification numbers), and members' names Not used if you use NIS to authenticate groups. CIFS only
netgroup Network groups NFS only
nsswitch.conf The order in which the filer contacts name services All
passwd Users' names, UIDs (user identification numbers), and primary GIDs Not used if you use NIS to authenticate users. CIFS and (PC)NFS
rc Script of commands to be executed when the filer is initializing All
serialnum Filer serial number and license codes, which help Network Appliance Technical Support process automatic email sent by the autosupport daemon All
shadow Encrypted password strings and password aging information Not used if you use NIS to authenticate users. CIFS and (PC)NFS

How the /home directory is used

How the /home directory is used depends on the file-sharing protocol used by the client. The following table describes how NFS and CIFS clients use the directory.

For NFS clients For CIFS clients
The /home directory is exported with read and write permissions to all NFS clients, and with root access to the administration host. Clients can mount directories after the filer host name is added to the filer /etc/hosts file or to the client's name server. The svtx bit (also known as the sticky bit) is set on the /home directory to prevent users from deleting each other's files. This is a safe configuration for networks that use UNIX permissions to provide security for network-accessible files. You can clear the sticky bit with the chmod command. The /home directory can be shared by CIFS users as the home share immediately after setup finishes. Before users can read and write files in the home share, you must follow the procedures in "Creating a home share for each user." By default, CIFS users can write and delete their own files in /home.
