| + | **ANTECEDENTES** | ||
| + | |||
| + | Tenemos una tarjeta de red, y queremos saber si soporta velocidades de 10000mbps (' | ||
| + | |||
| + | **SOLUCIÓN** | ||
| + | |||
| + | (Como root) | ||
| + | |||
| + | 1. Suponiendo que la tarjeta de red sea ' | ||
| + | |||
| + | dmesg | grep eth0 | ||
| + | [ 1.990066] e1000: eth0: e1000_probe: | ||
| + | [ 536.704969] e1000: eth0: e1000_watchdog: | ||
| + | [ 758.407797] eth0: no IPv6 routers present | ||
| + | |||
| + | En este caso va a 10mbps = mojón | ||
| + | |||
| + | Mejor instalar ethtool que te dice todo lo que soporta y a cuanto está ahora: | ||
| + | apt-get install ethtool | ||
| + | |||
| + | ethtool eth0 | ||
| + | | ||
| + | Settings for eth0: | ||

| + | **NOTAS** | ||
| + | |||
| + | Muy interesante la aportación de < | ||
| + | |||
| + | < | ||
| + | 1. Probar wget en lugar de scp | ||
| + | 2. El disco duro es el cuello de botella. Para no serlo debería ir a 15000 rpm | ||
| + | 3. Solo tarjetas de red integradas o pinchadas a PCI express dan esa velocidad | ||
