# NGINX Pathfinder Proxy - Documentação Técnica
## Visão Geral
Projeto de infraestrutura para Proxy Reverso de Alta Disponibilidade, utilizando Containers Docker para modularidade e fácil manutenção.
## Arquitetura de Containers
O projeto roda sobre 3 serviços orquestrados via `docker-compose.yml`:
| Serviço | Imagem | Porta Exposta | Função |
|---------|--------|---------------|--------|
| **modsecurity** | `owasp/modsecurity-crs:nginx-alpine` | `80`, `443` | **Frontend (WAF)**. Recebe todo o tráfego da internet, filtra ataques (SQLi, XSS) e encaminha requisições limpas para o Proxy. |
| **nginx-proxy** | `alpine` (Custom Build) | `8080` (Interna) | **Backend Proxy**. Gerencia vhosts, terminação SSL, cache, compressão Brotli e roteamento para as aplicações finais. |
| **fail2ban** | `crazymax/fail2ban` | - | **Watchdog**. Lê logs compartilhados dos dois containers acima e bane IPs maliciosos diretamente no host (via iptables). |
---
## Automação SSL
O sistema possui um mecanismo de **auto-cura** para certificados SSL.
### Componentes
1. **Certbot**: Instalado dentro do container `nginx-proxy`.
2. **Volumes**:
- `ssl/`: Onde ficam os arquivos `.crt` e `.key` usados pelo NGINX.
- `certbot/`: Onde o Certbot guarda os arquivos originais do Let's Encrypt.
3. **Scripts**:
- `scripts/inject_acme.sh`: Varre todos os arquivos em `conf.d/` e injeta o snippet de validação ACME (`.well-known`) se não existir.
- `scripts/renew_ssl.sh`:
1. Verifica a data de expiração de cada certificado ativo.
2. Se faltar **3 dias ou menos**, dispara `certbot renew`.
3. Copia os novos arquivos gerados para a pasta `ssl/`.
4. Recarrega o NGINX.
### Agendamento
- **Cron**: Configurado no `pre-flight.sh` para rodar todos os dias às **01:00 AM**.
- **Startup**: A verificação também roda a cada reinício do container.

## Módulos Especiais
### 1. Brotli & Headers More
O container `nginx-proxy` é construído manualmente (`Dockerfile`) para incluir módulos que não vêm por padrão no Alpine:
- `nginx-mod-http-brotli`
- `nginx-mod-http-headers-more`
### 2. ModSecurity (WAF)
Rodar o WAF em container separado (`modsecurity`) evita a necessidade de compilar o ModSecurity no NGINX principal.
**Arquitetura Customizada:**
- **Injeção de Template**: Um arquivo `modsec.conf.template` local é montado durante o boot para contornar limitações de permissão do container oficial. Ele instrui o NGINX a carregar regras customizadas.
- **Regras Modulares**: Localizadas em `modsec_rules/`, divididas por aplicação (`gitea-rule-exceptions.conf`, `nextcloud...`).
- **Global**: `global-exceptions.conf` define apenas a whitelist de rede.
- **Bypass de Emergência**: Se o WAF falhar, altere as portas no `docker-compose.yml` para expor o `nginx-proxy` diretamente.

## Comandos Operacionais
**Verificar status dos serviços:**
```bash
docker compose ps
```
**Verificar validade dos SSL (Log):**
```bash
docker compose logs nginx-proxy | grep "SSL"
```
**Forçar renovação SSL manualmente:**
```bash
docker compose exec nginx-proxy /scripts/renew_ssl.sh
```
**Reload Zero-Downtime (Blue-Green Logic):**
Este comando valida a configuração e executa um reload gracioso (`nginx -s reload`), onde novos workers assumem as novas configurações enquanto os antigos terminam as requisições correntes.
```bash
./scripts/reload.sh # Linux
./scripts/reload.ps1 # Windows PowerShell
```
**Banir um IP manualmente:**
```bash
docker compose exec fail2ban fail2ban-client set nginx-badbots banip 1.2.3.4
```
**Adicionar novo site:**
1. Criar `conf.d/novo-site.conf`
2. `docker compose restart nginx-proxy`
3. O script de startup irá validar o DNS e injetar o suporte ACME automaticamente.

# Tarefas Pendentes e Melhorias Futuras
## 1. Gestão Dinâmica de DNS
**Origem:** Migração de `legacy/hosts`
- **Problema:** O método atual usa `extra_hosts` no `docker-compose.yml`, que é estático e exige recriação do container para alterações.
- **Objetivo:** Mudar o modo de registro e atualização de DNS para ser mais dinâmico ou simples.
- **Ideias:** DNS containerizado (Bind/CoreDNS) ou Service Discovery.
## 2. Revisão de Regras ModSecurity
**Origem:** Migração de `legacy/nginx/modsecurity/*.conf` (Regras Antigas)
- **Status:** ✅ Concluído.
- **Resolução:** Regras refatoradas para estrutura modular (`modsec_rules/`). WAF ativo e configurado via template injection para Gitea, Nextcloud, Exchange, Zabbix e outros.
- **Ação:** Monitorar logs (`modsec_audit.log`) para ajustes finos futuros.
## 3. Atualizações Zero-Downtime (Sem Queda)
**Objetivo:** Criar um método para atualizar configurações de sites sem que clientes externos percam a conexão.
- **Status:** ✅ Concluído.
- **Solução Implementada:** Script `./scripts/reload.sh` que executa `nginx -t` e `nginx -s reload` (Reload Suave/Process-Level Blue-Green).
- **Como usar:** Execute `./scripts/reload.sh` após alterar qualquer `.conf`.
## 4. Conexão Direta na Interface do Host
**Objetivo:** Configurar o proxy para rotear tráfego tanto internamente (entre containers Docker) quanto externamente (para serviços fora do Docker).
- **Status:** 🧪 Implementado - Aguardando Teste no Host
- **Solução Implementada:**
- Adicionado `host.docker.internal:host-gateway` no `docker-compose.yml` para ambos containers
- Criado `snippets/docker_resolver.conf` para resolução DNS dinâmica de containers
- Criado `conf.d/test-connectivity.conf` (temporário) com endpoints de teste
- Atualizado diagrama de arquitetura no `README.md`
- **Testes Necessários (no host de deploy):**
```bash
# Rebuild e restart
docker compose build --no-cache nginx-proxy
docker compose down && docker compose up -d
# Testar conectividade
docker compose exec nginx-proxy ping -c 2 10.10.253.254
docker compose exec nginx-proxy ping -c 2 10.10.253.128
```
- **Após Validação:** Deletar `conf.d/test-connectivity.conf` e marcar como ✅ Concluído.

# Serviço de Sincronização de Configurações - Proxy-Sinc # NGINX Pathfinder Proxy
Este repositório contém as configurações e os scripts de automação para o serviço `proxy-sinc`, desenhado para automatizar o controlo de versões de ficheiros de configuração de servidores Linux para um repositório Git (Gitea). Solução moderna de Proxy Reverso containerizado, construída com NGINX, ModSecurity WAF e automação de SSL.
O objetivo é criar um sistema robusto, auto-documentado e fácil de gerir para o backup e o histórico de alterações de configurações críticas como as do Nginx e do Fail2ban. ## 🚀 Funcionalidades
## Funcionalidades Principais Implementadas pelo Instalador ### 🛡️ Segurança em Primeiro Lugar
- **ModSecurity WAF**: Conjunto de Regras OWASP (CRS) integrado rodando como proxy sidecar/frontend.
- **Fail2ban**: Serviço "cão de guarda" que bane IPs com comportamento suspeito (bots ruins, excesso de erros 4xx/5xx).
- **Mapas de Segurança**: Bloqueio automatizado de User-Agents maliciosos e restrições de rede interna.
### Gestão de Dependências ### ⚡ Performance
- **HTTP/3 (QUIC)**: Habilitado para conexões modernas de baixa latência.
- **Compressão Brotli**: Melhores taxas de compressão que o Gzip padrão.
- **Headers More**: Manipulação avançada de cabeçalhos para respostas limpas.
* Verifica e instala automaticamente as dependências necessárias (`git`, `rsync`) usando `apt`. ### 🔒 SSL Automatizado
- **Renovação Zero-Touch**: O Certbot integrado verifica a validade diariamente.
- **Auto-Renovação**: Renova automaticamente certificados próximos do vencimento (<= 3 dias).
- **Injeção Inteligente**: Injeta automaticamente os snippets de desafio ACME nas configurações dos sites.
### Configuração Interativa e Segura ---
* Pede ao utilizador a URL do repositório, o nome de utilizador do Gitea e um Token de Acesso (que fica oculto durante a digitação) para a autenticação. ## 🛠️ Como Trabalhar neste Repositório
* A URL do repositório é reconfigurada para incluir as credenciais, permitindo que as operações `git` futuras (como o `git push`) sejam executadas de forma não-interativa. ### Pré-requisitos
- Docker & Docker Compose instalados
- Acesso à internet (para baixar imagens e validar SSL)
### Identidade de Commit Automática ### 1. Implantar o Servidor (Deploy)
Para iniciar toda a infraestrutura:
```bash
./deploy.sh
```
*Este script detecta seu IP público, configura o ambiente e sobe os containers.*
* O nome do autor dos commits é automaticamente definido como o hostname completo do servidor (ex: `srvproxy001.itguys.com.br`). ### 2. Adicionar um Novo Site
Todas as configurações de sites ficam na pasta `conf.d/`.
* O email do autor é gerado automaticamente a partir do hostname (ex: `srvproxy001@itguys.com.br`). 1. **Crie o arquivo de configuração**:
Crie um arquivo `.conf` em `conf.d/` (ex: `meusite.com.br.conf`). Use um dos arquivos existentes como modelo.
**Modelo Básico (com SSL):**
```nginx
# Backend (para onde vai o tráfego)
upstream meu_backend {
server 192.168.1.10:8080;
}
### Gestão Inteligente de SSL # Redirecionamento HTTP -> HTTPS
server {
listen 80;
server_name meusite.com.br;
include /etc/nginx/snippets/acme_challenge.conf; # Importante para SSL
return 301 https://$host$request_uri;
}
* O script testa automaticamente a conexão com o Gitea. Se detetar um problema de certificado SSL (comum em ambientes internos), ele configura o repositório local para ignorar a verificação SSL, garantindo que a sincronização funcione. # Bloco HTTPS
server {
listen 443 ssl;
http2 on;
server_name meusite.com.br;
### Registo de Deploy ssl_certificate /etc/nginx/ssl/meusite.com.br.crt;
ssl_certificate_key /etc/nginx/ssl/meusite.com.br.key;
* Na primeira instalação num novo servidor, o script cria um ficheiro de registo (`_deployment_logs/hostname.md`) no repositório, documentando quem (utilizador do Gitea) instalou o serviço e quando, criando uma trilha de auditoria. include /etc/nginx/snippets/ssl_params.conf;
### Instalação como Serviço `systemd` location / {
proxy_pass http://meu_backend;
include /etc/nginx/includes/proxy_backend.conf;
}
}
```
* Gera e instala um serviço `systemd` (`proxy-sinc.service`) e um `timer` (`proxy-sinc.timer`). 2. **Aplique as alterações**:
```bash
docker compose restart nginx-proxy
```
*No reinício, o script de pre-flight validará o DNS e injetará configurações de SSL necessárias.*
* Esta abordagem é superior ao `cron` pois integra-se perfeitamente com o sistema de logs `journald`, permitindo uma gestão fácil com `systemctl status`, `start`, `stop`, etc. ### 3. Modificar Configurações Globais
As configurações globais são modularizadas na pasta `snippets/`.
* O timer está configurado para executar o script de sincronização **a cada minuto**. - **Rate Limiting**: Edite `snippets/rate_limit.conf` para ajustar os limites de requisições por segundo.
- **Bloqueio de Bots**: Edite `snippets/security_maps.conf` para adicionar novos User-Agents à lista negra.
- **Cache**: Edite `snippets/cache_zones.conf` para definir novas zonas ou tempos de cache.
### Sincronização Dinâmica de Ficheiros ### 3.1. Modificar Regras do WAF (ModSecurity)
O WAF agora utiliza uma estrutura modular de regras localizada na pasta `modsec_rules/`.
- **Arquivos Específicos**: Regras para Gitea, Nextcloud, Exchange, Zabbix, etc. ficam em seus respectivos arquivos `.conf`.
- **Global**: `global-exceptions.conf` contém apenas whitelists de rede interna.
- **Aplicação**: Após editar qualquer regra, reinicie o container do WAF para aplicar:
```bash
docker compose restart modsecurity
```
> **Nota Técnica**: O arquivo `modsec.conf.template` na raiz é injetado no container durante o boot para contornar problemas de permissão e garantir o carregamento das regras customizadas.
* O script principal de sincronização (`commit_configs.sh`) agora lê os caminhos a serem versionados a partir de um ficheiro de configuração central (`/etc/proxy-sinc/paths.conf`). ### 4. Gerenciar Certificados SSL
O sistema gerencia isso automaticamente, mas você pode intervir manualmente se necessário.
* Isto permite que os administradores adicionem ou removam ficheiros e pastas para sincronização no futuro, simplesmente editando este ficheiro de texto, sem precisar de alterar o script. - **Verificar Validade**:
Verifique os logs do startup para ver o status de todos os domínios:
```bash
docker compose logs nginx-proxy | grep "SSL"
```
### Auto-Versionamento - **Forçar Renovação**:
Se precisar renovar um certificado imediatamente:
```bash
docker compose exec nginx-proxy /scripts/renew_ssl.sh
```
* O script `commit_configs.sh` foi desenhado para se incluir a si mesmo e a todos os seus ficheiros de configuração e de serviço (`.service`, `.timer`, `man page`, `paths.conf`) no repositório Git. Desta forma, qualquer alteração na própria automação também é versionada. - **Reload sem Downtime (Recomendado)**:
Para aplicar alterações de configuração (vhosts, SSL) sem derrubar conexões ativas:
```bash
./scripts/reload.sh
```
### Funcionalidade de Auto-Atualização ### 5. Monitorar e Debugar
* Instala um novo comando no sistema, `proxy-sinc-update`. - **Verificar Status dos Containers**:
```bash
docker compose ps
```
* Quando executado, este comando baixa a versão mais recente do `setup.sh` a partir de uma URL pré-definida no repositório Gitea e executa-a, permitindo uma atualização fácil e centralizada de toda a automação. - **Ver Logs em Tempo Real**:
```bash
docker compose logs -f
```
### Documentação Integrada (`man page`) - **Verificar se o WAF (ModSecurity) bloqueou algo**:
```bash
docker compose logs modsecurity | grep "Access denied"
```
* Gera e instala uma página de manual (`man proxy-sinc`) no sistema. - **Verificar Banimentos do Fail2ban**:
```bash
docker compose exec fail2ban fail2ban-client status nginx-badbots
```
* O manual explica o que o serviço faz, como o gerir, como o atualizar e, o mais importante, como adicionar novos caminhos de ficheiros para serem sincronizados, tornando a ferramenta fácil de usar para qualquer membro da equipa no futuro. ---

# Relatório de Diagnóstico e Pontos de Dor (Pain Points)
Este documento sumariza os problemas arquiteturais e técnicos identificados durante a tentativa de estabilizar o stack `nginx-pathfinder-proxy`. O objetivo é fornecer um contexto claro para um futuro Agente de IA simplificar a solução.
## 1. Arquitetura Excessivamente Complexa (Split Container)
Atualmente, temos dois containers NGINX separados:
1. **Frontend (`modsecurity`)**: Recebe a internet, faz WAF, termina SSL.
2. **Backend (`nginx-proxy`)**: Recebe do WAF, faz roteamento, gerencia certificados (Certbot), roda scripts.
**Problemas Causados:**
- **Inferno de Permissões (Permission Hell):** O Backend (onde roda o Certbot) gera certificados no volume compartilhado como `root`. O Frontend tenta ler esses arquivos e falha com `Permission denied` porque roda com outro UID/GID. Tentar corrigir com `chmod` é frágil e inseguro.
- **Configuração Duplicada:** É preciso configurar o Nginx duas vezes. Uma no Frontend (para saber onde estão os certs) e uma no Backend (para saber como tratar a requisição na porta 8080).
- **SSL "Ping-Pong":** O Backend gerencia a renovação, mas o Frontend é quem *usa* o certificado. Isso exige reload sincronizado em dois containers diferentes.
## 2. Problema do "Ovo e a Galinha" (SSL Bootstrap)
- O NGINX **não sobe** se o arquivo de certificado não existir.
- O Certbot **não gera** o certificado se o NGINX não estiver rodando (para responder o desafio HTTP-01).
- **Solução Atual (Gambiarra):** Criamos um script complexo (`pre-flight.sh` + `renew_ssl.sh`) que gera certificados falsos (self-signed) só para o NGINX subir, e depois tenta baixar os reais. Isso adiciona muita lógica propensa a falhas.
## 3. Fragilidade de Deploy (Portainer / Docker)
- **Mount Error:** O Portainer falha ao tentar montar arquivos de configuração (`modsec_conf/...`) que ainda não foram baixados pelo git no host.
- **Solução Atual:** Tivemos que "assar" (bake) as configurações dentro da imagem Docker (`COPY conf.d ...`). Isso tira a agilidade de alterar uma config no git e dar deploy rápido; agora exige rebuild da imagem.
## 4. Scripts de Automação Frágeis
- O script `pre-flight.sh` tenta fazer `git clone/pull` dentro do container. Isso gera erros de "Resource busy" quando tenta limpar pastas montadas via volume.
- Lógica de `sed/grep` para ler arquivos `.conf` e achar domínios é suscetível a erros de sintaxe no arquivo de config.
---
# Recomendação de Simplificação (Para o Próximo Agente)
### Opção A: Single "Super" Container (Recomendada)
Unificar tudo em um único container.
- **Base:** Usar a imagem oficial com ModSecurity já compilado (ou compilar num multi-stage build).
- **Benefício:** Resolve problemas de permissão (mesmo processo lê e escreve). Resolve problema de setup (um único serviço). Remove complexidade de rede (sem proxy pass interno desnecessário).
### Opção B: Caddy Server (Radical)
Substituir NGINX + Certbot por **Caddy**.
- **Benefício:** Caddy tem HTTPS automático (resolve o problema do Ovo/Galinha nativamente).
- **WAF:** Existe plugin de WAF para Caddy (Coraza), mas exige validação se atende os requisitos de segurança do Oestepan.
### Opção C: NGINX Proxy Manager (GUI)
Usar uma solução pronta como NGINX Proxy Manager.
- Tem interface web.
- Gerencia SSL sozinho.
- Pode ser difícil integrar ModSecurity customizado.
### Resumo do Pedido de Refatoração

# Action to report IP address to abuseipdb.com
# You must sign up to obtain an API key from abuseipdb.com.
#
# NOTE: These reports may include sensitive Info.
# If you want cleaner reports that ensure no user data see the helper script at the below website.
#
# IMPORTANT:
#
# Reporting an IP of abuse is a serious complaint. Make sure that it is
# serious. Fail2ban developers and network owners recommend you only use this
# action for:
# * The recidive where the IP has been banned multiple times
# * Where maxretry has been set quite high, beyond the normal user typing
# password incorrectly.
# * For filters that have a low likelihood of receiving human errors
#
# This action relies on a api_key being added to the above action conf,
# and the appropriate categories set.
#
# Example, for ssh bruteforce (in section [sshd] of `jail.local`):
# action = %(known/action)s
# abuseipdb[abuseipdb_apikey="my-api-key", abuseipdb_category="18,22"]
#
# See below for categories.
#
# Added to fail2ban by Andrew James Collett (ajcollett)
## abuseIPDB Categories, `the abuseipdb_category` MUST be set in the jail.conf action call.
# Example, for ssh bruteforce: action = %(action_abuseipdb)s[abuseipdb_category="18,22"]

# Action to report IP address to blocklist.de
# Blocklist.de must be signed up to at www.blocklist.de
# Once registered, one or more servers can be added.
# This action requires the server 'email address' and the associated apikey.
#
# From blocklist.de:
# www.blocklist.de is a free and voluntary service provided by a
# Fraud/Abuse-specialist, whose servers are often attacked on SSH-,
# Mail-Login-, FTP-, Webserver- and other services.
# The mission is to report all attacks to the abuse departments of the
# infected PCs/servers to ensure that the responsible provider can inform
# the customer about the infection and disable them
#
# IMPORTANT:
#
# Reporting an IP of abuse is a serious complaint. Make sure that it is
# serious. Fail2ban developers and network owners recommend you only use this
# action for:
# * The recidive where the IP has been banned multiple times
# * Where maxretry has been set quite high, beyond the normal user typing
# password incorrectly.
# * For filters that have a low likelihood of receiving human errors

# This is for ipset protocol 4 (ipset v4.2). If you have a later version
# of ipset try to use the iptables-ipset-proto6.conf as it does some things
# nicer.
#
# This requires the program ipset which is normally in package called ipset.
#
# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0 kernels.
#
# If you are running on an older kernel you make need to patch in external
# modules. Debian squeeze can do this with:
# apt-get install xtables-addons-source
# module-assistant auto-install xtables-addons
#
# Debian wheezy and above uses protocol 6

# IPThreat configuration file
#
# Added to fail2ban by Jeff Johnson (jjxtra)
#
# Action to report IP address to ipthreat.net
#
# You must sign up to obtain an API key from ipthreat.net and request bulk report permissions
# https://ipthreat.net/integrations
#
# IPThreat is a 100% free site and service, all data is licensed under a creative commons by attribution license
# Please do not integrate if you do not agree to the license
#
# IMPORTANT:
#
# Reporting an IP is a serious action. Make sure that it is legit.
# Consider using this action only for:
# * IP that has been banned more than once
# * High max retry to avoid user mis-typing password
# * Filters that are unlikely to be human error
#
# Example:
# ```
# action = %(known/action)s
# ipthreat[]
# ```
#
# The action accepts the following arguments: ipthreat[ipthreat_flags="8",ipthreat_system="SSH", ipthreat_apikey=...]
# In most cases your action could be as simple as: ipthreat[], since the default flags and system are set to the most correct default values.
# You can optionally override ipthreat_system and ipthreat_flags if desired.
# The ipthreat_apikey must be set at the bottom of this configuration file.
#
# `ipthreat_system` is a short name of the system attacked, i.e. SSH, SMTP, MYSQL, PHP, etc.
#
# For `ipthreat_flags`, most cases will use 8 (BruteForce) which is the default, but you could use others.
# You can use the name or the ordinal.
# Multiple values are comma separated.
# ```
# Name Ordinal Description
# Dns 1 Abuse/attack of dns (domain name server)
# Fraud 2 General fraud, whether orders, misuse of payment info, etc
# DDos 4 Distributed denial of service attack, whether through http requests, large ping attack, etc
# BruteForce 8 Brute force login attack
# Proxy 16 IP is a proxy like TOR or other proxy server
# Spam 32 Email, comment or other type of spam
# Vpn 64 IP is part of a VPN
# Hacking 128 General hacking outside of brute force attack (includes vulnerability scans, sql injection, etc.). Use port scan flag instead if it's just probe on ports.
# BadBot 256 Bad bot that is not honoring robots.txt or just flooding with too many requests, etc
# Compromised 512 The ip has been taken over by malware or botnet
# Phishing 1024 The ip is involved in phishing or spoofing
# Iot 2048 The ip has targetted an iot (Internet of Things) device
# PortScan 4096 Port scan
# See https://ipthreat.net/bulkreportformat for more information

# Fail2ban Citrix Netscaler Action
# by Juliano Jeziorny
# juliano@jeziorny.eu
#
# The script will add offender IPs to a dataset on netscaler, the dataset can then be used to block the IPs at a cs/vserver or global level
# This dataset is then used to block IPs using responder policies on the netscaler.
#
# The script assumes using HTTPS with unsecure certificate to access the netscaler,
# if you have a valid certificate installed remove the -k from the curl lines, or if you want http change it accordingly (and remove the -k)
#
# This action depends on curl
#
# You need to populate the 3 options inside Init
#
# ns_host: IP or hostname of netslcaer appliance
# ns_auth: username:password, suggest base64 encoded for a little added security (echo -n "username:password" | base64)
# ns_dataset: Name of the netscaler dataset holding the IPs to be blocked.
#
# For further details on how to use it please check http://blog.ckzone.eu/2017/01/fail2ban-action-for-citrix-netscaler.html

# Fail2Ban configuration file for black-listing via nginx
#
# Author: Serg G. Brester (aka sebres)
#
# To use 'nginx-block-map' action you should define some special blocks in your nginx configuration,
# and use it hereafter in your locations (to notify fail2ban by failure, resp. nginx by ban).
#
# Example (argument "token_id" resp. cookie "session_id" used here as unique identifier for user):
#
# http {
# ...
# # maps to check user is blacklisted (banned in f2b):
# #map $arg_token_id $blck_lst_tok { include blacklisted-tokens.map; }
# map $cookie_session_id $blck_lst_ses { include blacklisted-sessions.map; }
# ...
# # special log-format to notify fail2ban about failures:
# log_format f2b_session_errors '$msec failure "$cookie_session_id" - $remote_addr - $remote_user '
# ;# '"$request" $status $bytes_sent '
# # '"$http_referer" "$http_user_agent"';
#
# # location checking blacklisted values:
# location ... {
# # check banned sessionid:
# if ($blck_lst_ses != "") {
# try_files "" @f2b-banned;
# }
# ...
# # notify fail2ban about a failure inside nginx:
# error_page 401 = @notify-f2b;
# ...
# }
# ...
# # location for return with "403 Forbidden" if banned:
# location @f2b-banned {
# default_type text/html;
# return 403 "<br/><center>
# <b style=\"color:red; font-size:18pt; border:2pt solid black; padding:5pt;\">
# You are banned!</b></center>";
# }
# ...
# # location to notify fail2ban about a failure inside nginx:
# location @notify-f2b {
# access_log /var/log/nginx/f2b-auth-errors.log f2b_session_errors;
# }
# }
# ...
#
# Note that quote-character (and possibly other special characters) are not allowed currently as session-id.
# Thus please add any session-id validation rule in your locations (or in the corresponding backend-service),
# like in example below:
#
# location ... {
# if ($cookie_session_id !~ "^[\w\-]+$") {
# return 403 "Wrong session-id"

# datepattern = ^Epoch
# failregex = ^ failure "<F-ID>[^"]+</F-ID>" - <ADDR>
# usedns = no

# This is for blocking whole hosts through blackhole routes.
#
# PRO:
# - Works on all kernel versions and as no compatibility problems (back to debian lenny and WAY further).
# - It's FAST for very large numbers of blocked ips.
# - It's FAST because it Blocks traffic before it enters common iptables chains used for filtering.
# - It's per host, ideal as action against ssh password bruteforcing to block further attack attempts.
# - No additional software required beside iproute/iproute2
#
# CON:
# - Blocking is per IP and NOT per service, but ideal as action against ssh password bruteforcing hosts

# Fail2Ban configuration file
#
# Author: Eduardo Diaz
#
# This is for ipset protocol 6 (and hopefully later) (ipset v6.14).
# for shorewall
#
# Use this setting in jail.conf to modify use this action instead of a
# default one
#
# banaction = shorewall-ipset-proto6
#
# This requires the program ipset which is normally in package called ipset.
#
# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0
# kernels, and you need Shorewall >= 4.5.5 to use this action.
#
# The default Shorewall configuration is with "BLACKLISTNEWONLY=Yes" (see
# file /etc/shorewall/shorewall.conf). This means that when Fail2ban adds a
# new shorewall rule to ban an IP address, that rule will affect only new
# connections. So if the attacker goes on trying using the same connection
# he could even log in. In order to get the same behavior of the iptable
# action (so that the ban is immediate) the /etc/shorewall/shorewall.conf
# file should me modified with "BLACKLISTNEWONLY=No".
#
#
# Enable shorewall to use a blacklist using iptables creating a file
# /etc/shorewall/blrules and adding "DROP net:+f2b-ssh all" and
# similar lines for every jail. To enable restoring you ipset you
# must set SAVE_IPSETS=Yes in shorewall.conf . You can read more
# about ipsets handling in Shorewall at http://shorewall.net/ipsets.html
#
# To force creation of the ipset in the case that somebody deletes the
# ipset create a file /etc/shorewall/initdone and add one line for
# every ipset (this files are in Perl) and add 1 at the end of the file.
# The example:
# system("/usr/sbin/ipset -quiet -exist create f2b-ssh hash:ip timeout 600 ");
# 1;
#
# To destroy the ipset in shorewall you must add to the file /etc/shorewall/stopped
# # One line of every ipset
# system("/usr/sbin/ipset -quiet destroy f2b-ssh ");
# 1; # This must go to the end of the file if not shorewall compilation fails
