Cacti automatically uses the Net-SNMP binaries where php-snmp cannot be
used (SNMPv3 with advanced ciphers, IPv6, bulkwalk, hex output), so users
no longer need to uninstall php-snmp. Reword the SNMP Version 3 note in
Devices.md, soften the optional snmp module note in Requirements.md, and
drop the php-snmp caveat from the SNMP Timeout field in
How-to-Graph-Your-Network.md.

* docs: comprehensive audit, Spine poller overhaul, and technical refactor
- Overhaul Spine documentation (Spine.md) with complete end-to-end guide: architecture, prerequisites for modern distros (EL8/9 CRB, Ubuntu 22/24, Debian 11/12, FreeBSD), SUID root permissions, secure spine.conf setup (0640), Web UI configuration (Paths, Poller type, Data Collectors tuning), MySQL max_connections sizing, and troubleshooting.
- Fix broken links and anchors (Hardening, SNMP data queries, Hook API references).
- Fix broken image reference in Sites.md (add-site.JPG -> add-site.png).
- Fix syntax errors in documentation PHP code blocks, including invalid parenthesization, missing SQL execute quotes, and malformed comments in FAQ.
- Fix DevOps installation commands: use config.php.dist, correct systemctl service names for MySQL/MariaDB/PHP-FPM, remove nonexistent php-json, add missing composer install, and correct Debian/Ubuntu systemd environment path.
- Correct grammatical errors, repeated words, and typos across all markdown documents.
- Remove obsolete unreferenced duplicate installation guides.

* docs: correct guidance that disagrees with the Cacti source
Verified each claim against include/global_arrays.php, lib/auth.php,
lib/functions.php, host_templates.php and the Spine config parser. The
notable ones: api_plugin_safe_exec() does not exist on either branch,
Spine reads DB_Pass rather than DB_Password, and the CDEF special data
source table was missing five entries and renamed four others.

LAMP fixes:
- Title updated to reflect RHEL/Rocky Linux/AlmaLinux coverage
- Fix step numbering: "2.Install" / "3.Enable" missing space after number
- Spine build deps: restructure for EL7/EL8/EL9+ separately; EL8 was
missing package install after repo enable; EL9+ uses 'crb' not 'powertools'
- SELinux URL: fix quadruple-slash typo; switch to English wiki URL
LEMP fixes:
- Title: "CentOS 7" → "Enterprise Linux (RHEL / Rocky Linux / AlmaLinux)"

set ssl_protocols TLSv1.2 TLSv1.3
- Ciphers: remove DH+3DES (Sweet32 / CVE-2016-2183)
- HTTP redirect: uncomment return 301 (comment claiming nginx lacks support
for 'return' has been wrong since nginx 0.8 / 2009)
- PHP location block: fix 'alias' → 'root' (alias breaks $document_root in
fastcgi_param SCRIPT_FILENAME); add missing semicolon after index directive
- Cron: poller path was /var/www/html/cacti but install target throughout
this guide is /usr/share/nginx/html/cacti — align them

on GRANT removed in MySQL 8.0 / MariaDB 10.5.2)

Installing-Under-Windows.md:
- Replace php_mysql.dll with php_pdo_mysql.dll (php_mysql removed in PHP 7.0)
- Remove IIS ISAPI steps referencing php8isapi.dll (ISAPI dropped in PHP 8.0);
replace with FastCGI instructions via php-cgi.exe
- Remove NO_AUTO_CREATE_USER from sql_mode (removed MySQL 8.0, breaks startup)
- sort_buffer_size = 200M → 32M with caveat (per-session; 200M causes OOM under load)
- Fix step numbering gaps: main list 5→8, IIS 3→5, Finishing 5→8
- "you will have to user 8.3 notation" → "use"
- "c:cygwin" → "c:\cygwin" (missing backslash)

- mysqldump: remove contradictory -l / --lock-tables=false flags;
replace with --single-transaction (correct for InnoDB, no locking)
How-To-SSH-Tunnels.md:
- Add prominent note: SSH -L is TCP-only; standard SNMP uses UDP; this
guide requires TCP transport configured on snmpd and does not work for
most network devices
- Fix unclosed code fence after ssh-keygen output block
- Replace rc.local persistence with systemd unit (rc.local is deprecated
and disabled by default on systemd distros: Ubuntu 16.04+, Debian 9+)
- ssh-keygen: recommend ed25519 over RSA
* docs: correct PHP 8.1 EOL date, Net-SNMP link, and grammar
PHP 8.1 security support ended 31 December 2025, not November 2024. Point the
snmpd.conf link at www.net-snmp.org (the sourceforge.io mirror is bot-blocked).
Fix 'There a two ways extending' to 'There are two ways to extend'.

* ci: fix spelling workflow trigger to target develop, not main
The repo's default branch is develop; main hasn't moved since 2023.
The workflow's push/pull_request filters targeted main, so it never
ran on any PR opened against develop.
