# Cisco MAC Monitor - HTTPS Secure Service Guide
|
|
|
|
## 🔒 Servicio HTTPS Seguro Deployado
|
|
|
|
¡El servicio HTTPS con POST seguro está funcionando perfectamente! Las credenciales ya NO se envían por URLs.
|
|
|
|
### 🛡️ Mejoras de Seguridad Implementadas
|
|
|
|
✅ **POST en lugar de GET**: Credenciales en JSON body, no en URL
|
|
✅ **HTTPS/SSL**: Cifrado TLS con certificado autofirmado
|
|
✅ **JSON Body**: Datos estructurados y seguros
|
|
✅ **Logs limpios**: No aparecen credenciales en logs
|
|
|

|
|
|
|
## 🌐 API Endpoints
|
|
|
|
### 🔐 Monitorización MAC (Seguro)
|
|
```http
|
|
POST /mac-monitor
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"host": "192.168.1.10",
|
|
"username": "admin",
|
|
"password": "cisco123",
|
|
"hostname": "SW-CORE-001", // Opcional
|
|
"port": 22, // Opcional, default: 22
|
|
"timeout": 30 // Opcional, default: 30
|
|
}
|
|
```
|
|
|
|
### 📊 Health Check
|
|
```http
|
|
GET /health
|
|
```
|
|
|
|
### 📈 Métricas
|
|
```http
|
|
GET /metrics
|
|
```
|

## 🚀 Uso del Servicio
|
|
|
|
### Con curl
|
|
```bash
|
|
# Monitorización básica
|
|
curl -k -X POST "https://localhost:8443/mac-monitor" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"host":"10.150.226.19","username":"itops","password":"Tr4!D0r3s"}'
|
|
|
|
# Con parámetros completos
|
|
curl -k -X POST "https://localhost:8443/mac-monitor" \
|
|
-H "Content-Type: application/json" \
|
|
-d '{
|
|
"host": "10.150.226.19",
|
|
"username": "itops",
|
|
"password": "Tr4!D0r3s",
|
|
"hostname": "SW-CORE-BUILDING-A",
|
|
"timeout": 45
|
|
}'
|
|
|
|
# Health check
|
|
curl -k "https://localhost:8443/health"
|
|
```
|
|
|
|
### Con Python
|
|
```python
|
|
import requests
|
|
import json
|
|
|
|
# Configuración
|
|
url = "https://localhost:8443/mac-monitor"
|
|
payload = {
|
|
"host": "10.150.226.19",
|
|
"username": "itops",
|
|
"password": "Tr4!D0r3s",
|
|
"hostname": "SW-CORE-TEST"
|
|
}
|
|
|
|
# Petición segura
|
|
response = requests.post(
|
|
url,
|
|
json=payload,
|
|
verify=False # Para certificado autofirmado
|
|
)
|
|
|
|
if response.status_code == 200:
|
|
data = response.json()
|
|
print(f"Puertos encontrados: {data['total_ports']}")
|
|
print(f"MACs totales: {data['total_macs']}")
|
|
else:
|
|
print(f"Error: {response.status_code} - {response.text}")
|
|
```

## 🐳 Gestión del Servicio HTTPS
|
|
|
|
### Comandos Docker
|
|
|
|
```bash
|
|
# Iniciar servicio HTTPS (recomendado)
|
|
docker run -d -p 8443:8443 --name cisco-mac-https localhost/los-vecinos-de-cisco:https-service
|
|
|
|
# Ver logs en tiempo real
|
|
docker logs -f cisco-mac-https
|
|
|
|
# Reiniciar servicio
|
|
docker restart cisco-mac-https
|
|
|
|
# Detener servicio
|
|
docker stop cisco-mac-https && docker rm cisco-mac-https
|
|
|
|
# Verificar estado
|
|
docker ps | grep cisco-mac-https
|
|
```
|
|
|
|
### Reconstruir tras cambios
|
|
```bash
|
|
# Reconstruir imagen
|
|
docker build --platform linux/amd64 -f Dockerfile.http -t localhost/los-vecinos-de-cisco:https-service .
|

# Recrear contenedor
|
|
docker stop cisco-mac-https && docker rm cisco-mac-https
|
|
docker run -d -p 8443:8443 --name cisco-mac-https localhost/los-vecinos-de-cisco:https-service
|
|
```
|
|
|

|
|
|
|
## 📋 Integración con Zabbix
|
|
|
|
### Script de External Check Actualizado
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
# /usr/lib/zabbix/externalscripts/cisco_mac_https_discovery.sh
|
|
|
|
HOST="$1"
|
|
USERNAME="$2"
|
|
PASSWORD="$3"
|
|
HOSTNAME="${4:-$HOST}"
|
|
|
|
# Crear JSON payload
|
|
JSON_PAYLOAD=$(cat <<EOF
|
|
{
|
|
"host": "${HOST}",
|
|
"username": "${USERNAME}",
|
|
"password": "${PASSWORD}",
|
|
"hostname": "${HOSTNAME}"
|
|
}
|
|
EOF
|
|
)
|
|
|
|
# Petición HTTPS segura
|
|
curl -k -s -X POST "https://localhost:8443/mac-monitor" \
|
|
-H "Content-Type: application/json" \
|
|
-d "${JSON_PAYLOAD}"
|
|
```
|
|
|
|
### Configuración Zabbix
|
|
|
|
**Discovery Rule:**
|
|
```xml
|
|
Name: Cisco MAC HTTPS Discovery
|
|
Type: External check
|
|
Key: cisco_mac_https_discovery.sh[{HOST.IP},{$CISCO_USER},{$CISCO_PASSWORD},{HOST.NAME}]
|
|
Update interval: 5m
|
|
```
|
|
|
|
**Macros requeridas:**
|
|
```xml
|
|
{$CISCO_USER} = admin
|
|
{$CISCO_PASSWORD} = cisco123
|
|
```
|
|
|
|
---
|
|
|
|
## 🔒 Certificados SSL
|
|
|
|
### Certificado Autofirmado (Por Defecto)
|
|
El servicio genera automáticamente un certificado autofirmado:
|
|
```
|
|
Subject: /C=ES/ST=Madrid/L=Madrid/O=CiscoMonitor/CN=cisco-mac-monitor
|
|
Validity: 365 days
|
|
Location: /tmp/cisco_mac_server.crt
|
|
```
|
|
|
|
### Certificado Personalizado (Producción)
|
|
```bash
|
|
# Con certificados propios
|
|
docker run -d -p 8443:8443 \
|
|
-v /path/to/cert.pem:/app/cert.pem \
|
|
-v /path/to/key.pem:/app/key.pem \
|
|
--name cisco-mac-https \
|
|
localhost/los-vecinos-de-cisco:https-service \
|
|
--ssl-cert /app/cert.pem --ssl-key /app/key.pem
|
|
```
|
|
|
|
### Para Desarrollo (HTTP sin SSL)
|
|
```bash
|
|
# Solo para testing local
|
|
docker run -d -p 8080:8080 --name cisco-mac-http \
|
|
localhost/los-vecinos-de-cisco:https-service \
|
|
--port 8080
|
|
```

|
# Debería devolver error 405 "Método no permitido"
|
|
|
|
# Verificar SSL
|
|
openssl s_client -connect localhost:8443 -servername cisco-mac-monitor
|
|
