cifs-utils-7.0

Introduction to cifs-utils

The cifs-utils package provides a means for mounting SMB/CIFS shares on a Linux system.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

cifs-utils Dependencies

Recommended

Optional

docutils-0.20.1 (to create the man pages), keyutils-1.6.3 (required to build PAM module), Linux-PAM-1.6.0, Samba-4.19.5, and libcap-2.69 with PAM or libcap-ng

Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel if necessary:

File systems --->
  [*] Network File Systems --->                            [NETWORK_FILESYSTEMS]
    <*/M> SMB3 and CIFS support (advanced network filesystem)             [CIFS]

Depending on your server configuration, additional kernel options may be required.

Installation of cifs-utils

Install cifs-utils by running the following commands:

./configure --prefix=/usr \
            --disable-pam \
            --disable-systemd &&
make

This package does not come with a test suite.

Now, as the root user:

make install

Command Explanations

--disable-pam: Do not build PAM support. Remove it and use --with-pamdir (see below), if Linux-PAM-1.6.0 is installed and you wish PAM support.

--disable-systemd: Disable systemd specific behavior for mount.cifs.

--with-pamdir=/usr/lib/security: Install the PAM module in /usr/lib/security.

Short Descriptions

cifs.idmap

is a userspace helper program for the linux CIFS client filesystem. There are a number of activities that the kernel cannot easily do itself. This program is a callout program that does these things for the kernel and then returns the result. It is not intended to be run from the command-line

cifs.upcall

is a userspace helper program for the linux CIFS client filesystem. It is intended to be run when the kernel calls request-key for a particular key type. It is not intended to be run from the command-line

cifscreds

is a tool for managing credentials (username and password) for the purpose of establishing sessions in multiuser mounts

getcifsacl

is a userspace helper to display an ACL in a security descriptor for Common Internet File System (CIFS)

mount.cifs

mounts a Linux CIFS filesystem. It is usually invoked indirectly by the mount(8) command when using the -t cifs option

mount.smb3

mounts a SMB3-based filesystem. It is usually invoked indirectly by the mount(8) command when using the -t smb3 option

setcifsacl

is intended to alter an ACL of a security descriptor for a file system object

smb3-quota

displays quota information for a SMB filesystem

smbinfo

displays SMB-specific file information, such as security descriptors and quotas
