# DESCRIPTION
1620

17-
**lddd** scans the system for packages with broken shared library links. It identifies binaries that depend on libraries that have been removed or updated, indicating packages that may need to be rebuilt.
21+
**lddd** scans every directory in **$PATH**, plus **/lib**, **/usr/lib**, **/usr/local/lib** and the directories listed in **/etc/ld.so.conf.d/**, for ELF files. Each ELF file is run through **ldd**, and any file with a "not found" dependency is recorded.
22+
23+
The affected files are then mapped to their owning packages with **pacman -Qo**, giving a list of packages that probably need to be rebuilt, typically after a soname bump of a library. It takes no options or arguments.
24+
25+
All results are written to a temporary directory created with **mktemp** (for example **/tmp/lddd-script.XXXX**):
26+
27+
**raw.txt**
28+
> Every affected file followed by the missing libraries.
29+
30+
**affected-files.txt**
31+
> Paths of the affected files only.

This tool is specifically designed for Arch Linux systems and helps maintain system health after library updates.

Only available on Arch Linux. May take considerable time on systems with many packages. Requires root privileges for complete system scanning.
41+
Arch Linux specific; part of the **devtools** package. The scan runs **file** and **ldd** on every candidate file and can take a long time. Run it as a user that can read all scanned files, otherwise some may be skipped. Files not owned by any package (e.g. in /usr/local) show up in raw.txt but not in the package list.

# DESCRIPTION

**limits.conf** is a PAM configuration file that sets resource limits for users and groups. Limits are enforced when users log in through PAM-enabled services.
123+
**limits.conf** is the configuration file for the **pam_limits** module, which applies ulimit limits, nice priority and login-count limits to user sessions opened through PAM. Files in **/etc/security/limits.d/** with a **.conf** suffix are read as well.
56124

57-
The format is: domain type item value. Domain can be username, @groupname, or * for all users.
125+
Each line has the format: domain type item value. Values **-1**, **unlimited** or **infinity** mean no limit (except for priority, nice and nonewprivs). Individual user entries take priority over group entries. Lines starting with **#** are comments.

Requires the pam_limits module in the relevant PAM service stack. Changes apply at the next login, not to running sessions. Limits are per session, not global (except maxlogins). The **\*** wildcard does not apply to root, which needs explicit entries. Systemd services ignore this file; use **LimitNOFILE=** and similar directives in unit files, or **DefaultLimitNOFILE=** in systemd's system.conf.

**linode-cli nodebalancers** manages Linode NodeBalancers. NodeBalancers distribute traffic across instances.
140+
**linode-cli nodebalancers** manages Linode (Akamai Cloud) NodeBalancers, managed load balancers that distribute incoming traffic across backend Linodes.
67141

68-
The tool configures load balancing, health checks, and SSL termination for high availability.
142+
Each NodeBalancer has one or more **configs**, one per listening port, which define the protocol, algorithm, session stickiness, TLS termination and health checks. Each config has its own set of backend **nodes**. Run **linode-cli nodebalancers** _action_ **--help** to see every argument for an action.

Requires authentication. Billed hourly. Needs backend nodes configured.
146+
Requires a configured API token (**linode-cli configure** or **LINODE_CLI_TOKEN**). NodeBalancers are billed hourly up to a monthly cap. Backend nodes should use private IPs in the same region. Available flags are generated from the Linode API specification and change with CLI updates.
