The configurable ncurses interface displays all the classic resource usage

It can also list the processes responsible in a @command{top}-like table.

A less common nmon feature is its ability to create highly detailed log files
in @acronym{CSV, comma-separated values} format.  These can be imported into
spreadsheets or fed straight into an @acronym{RRD, round-robin database} using
@command{rrdtool} for further analyisis, or to create colourful graphs.")

subsystems as operating system kernel interfaces.  It can stress the CPU, cache,
disk, memory, socket and pipe I/O, scheduling, and much more, in various
selectable ways.  This can trip hardware issues such as thermal overruns as well
as operating system bugs that occur only when a system is being thrashed hard.

You can also measure test throughput rates, which can be useful to observe
performance changes across different operating system releases or types of
hardware.  However, stress-ng is not a benchmark.  Use it with caution: some of
the tests can make poorly designed hardware run dangerously hot or make the
whole system lock up.

Compared to its inspiration, @command{stress}, @command{stress-ng} offers many
additional options such as the number of bogo operations to run, execution
metrics, verification of memory and computational operations, and considerably
more stress mechanisms.")

The roles are written with a high customization in mind, which can be done
using Ansible inventory.  This way the role and playbook code can be shared
between multiple environments, with different configuration in to each one.

Services can be managed on a single host, or spread between multiple hosts.
DebOps provides support for different SQL and NoSQL databases, web servers,
programming languages and specialized applications useful in a data center

virtualization environments using KVM/libvirt, Docker or LXC technologies to

    (description
     "Pam-krb5 is a Kerberos PAM module for either MIT Kerberos or Heimdal.
It supports ticket refreshing by screen savers, configurable
authorization handling, authentication of non-local accounts for network
services, password changing, and password expiration, as well as all the
standard expected PAM features.  It works correctly with OpenSSH, even
with @code{ChallengeResponseAuthentication} and @code{PrivilegeSeparation}
enabled, and supports extensive configuration either by PAM options or in
krb5.conf or both.  PKINIT is supported with recent versions of both MIT
Kerberos and Heimdal and FAST is supported with recent MIT Kerberos.")

In indent mode, your script is reformatted with standard spacing.

In tokenize mode, you can see the elements of every command you use.

It supports mounting local filesystems of any kind the normal mount utility
supports.  It can also mount encrypted LUKS volumes using the password
supplied by the user when logging in.

This package inherits pam-mount in the way that it is compiled specifically
for use with greetd daemon. It uses different configuration location and
name space for storing data in PAM.

greetd-pam-mount is used in configuration of greetd to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR in the way that it will not
interfere with default pam-mount configuration.")))

    (description
     "Fail2Ban scans log files like @file{/var/log/auth.log} and bans IP
addresses conducting too many failed login attempts.  It does this by updating
system firewall rules to reject new connections from those IP addresses, for a
configurable amount of time.  Fail2Ban comes out-of-the-box ready to read many
standard log files, such as those for sshd and Apache, and is easily
configured to read any log file of your choosing, for any error you wish.

Though Fail2Ban is able to reduce the rate of incorrect authentication
attempts, it cannot eliminate the risk presented by weak authentication.  Set
up services to use only two factor, or public/private authentication
mechanisms if you really want to protect services.")
