The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
dmfilemapd — device-mapper filemap monitoring daemon Synopsis dmfilemapd [file_descriptor] [group_id] [abs_path] [mode] [foreground[verbose]] Description The dmfilemapd daemon monitors groups of dmstats regions that correspond to the extents of a file, adding and removing regions to reflect the changing state of the file on-disk.

dlm_stonith – a proxy for fencing via stonith/pacemaker Synopsis dlm_stonith Description dlm_controld can use dlm_stonith as a proxy fence agent when the stonith/pacemaker system performs actual fencing. dlm_stonith is run by dlm_controld, and is not meant to be run manually. dlm_controld provides the options on stdin as key=val; command line options are for testing. If…
dlm_selinux – Security Enhanced Linux Policy for the dlm processes Description Security-Enhanced Linux secures the dlm processes via flexible mandatory access control.

dlm_controld – dlm cluster control daemon Synopsis dlm_controld [OPTIONS] Description The kernel dlm requires a user daemon to manage lockspace membership. dlm_controld manages lockspace membership using corosync cpg groups, and translates membership changes into dlm kernel recovery events. dlm_controld also manages posix locks for cluster file systems using the dlm. Options Command line options override…
dkms – Dynamic Kernel Module Support Synopsis dkms [ action ] [options ] [module/module-version ] [/path/to/source-tree ] [/path/to/tarball.tar ] [/path/to/driver.rpm ] Description dkms is a framework which allows kernel modules to be dynamically built for each kernel on your system in a simplified and organized fashion. Actions add [ module/module-version ] [/path/to/source-tree ] [/path/to/tarball.tar ] Adds a module/module-version combination to the tree for builds…

The dkim_milter processes execute with the dkim_milter_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep…
distcache – Distributed session caching Description The distcache architecture provides a protocol and set of accompanying tools to allow applications, and indeed machines, to share session state between them by way of a network service. The primary use of distcache right now is SSL/TLS session caching. This allows SSL/TLS servers (eg. a secure Apache web…
