cifs-utils-7.0

Introduction to cifs-utils

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

This package is known to build and work properly using an LFS 11.3 platform.

Package Information

cifs-utils Dependencies

Recommended

Optional

docutils-0.19 (to create the man pages), keyutils-1.6.1 (required to build PAM module), Linux-PAM-1.5.2, Samba-4.17.5, and libcap-2.67 with PAM or libcap-ng

User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/cifsutils

Kernel Configuration

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

File systems  --->
  [*] Network File Systems  --->                              [CONFIG_NETWORK_FILESYSTEMS]
    <*/M> SMB3 and CIFS support (advanced network filesystem) [CONFIG_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-1.5.2 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
