En una entrada de la semana pasada vimos como el nuevo Oracle Linux 7 y RedHat 7 han decidido cambiar los servicios y las notaciones a un nuevo m\u00e9todo con mejoras a mi entender altamente cuestionables.<\/p>\n

Hoy vamos a ver como podemos cambiar los interfaces de red de esa notaci\u00f3n a la notaci\u00f3n cl\u00e1sica de linux ethX<\/b>.<\/p>\n

La instalacion por defecto de Oracle Linux 7 nos dejar\u00e1 unos interfaces de red tal que as\u00ed<\/p>\n

\"Captura<\/a><\/p>\n

Para volver a tener nuestros interfaces de red con nuestros nombres habituales deberemos de hacer:<\/p>\n

\r\n[root@alone ~]# vi \/etc\/default\/grub\r\nGRUB_TIMEOUT=5\r\nGRUB_DISTRIBUTOR=\"$(sed 's, release .*$,,g' \/etc\/system-release)\"\r\nGRUB_DEFAULT=saved\r\nGRUB_DISABLE_SUBMENU=true\r\nGRUB_TERMINAL_OUTPUT=\"console\"\r\nGRUB_CMDLINE_LINUX=\"vconsole.keymap=es \r\ncrashkernel=auto vconsole.font=latarcyrheb-sun16 rhgb quiet \"\r\nGRUB_DISABLE_RECOVERY=\"true\"\r\n<\/pre>\n
Y modificaremos la l\u00ednea<\/p>\n
\r\nGRUB_CMDLINE_LINUX=\"vconsole.keymap=es crashkernel=auto \r\n vconsole.font=latarcyrheb-sun16 rhgb quiet \u201d<\/pre>\n
a\u00f1adi\u00e9ndole net.ifnames=0 biosdevname=0<\/b> para que quede:<\/p>\n
\r\n[root@alone ~]# vi \/etc\/default\/grub\r\nGRUB_TIMEOUT=5\r\nGRUB_DISTRIBUTOR=\"$(sed 's, release .*$,,g' \/etc\/system-release)\"\r\nGRUB_DEFAULT=saved\r\nGRUB_DISABLE_SUBMENU=true\r\nGRUB_TERMINAL_OUTPUT=\"console\"\r\nGRUB_CMDLINE_LINUX=\"vconsole.keymap=es \r\ncrashkernel=auto vconsole.font=latarcyrheb-sun16 rhgb quiet net.ifnames=0 biosdevname=0\"\r\nGRUB_DISABLE_RECOVERY=\"true\"\r\n<\/pre>\n
Tras esto ejecutamos la utilidad grub2-mkconfig -o \/boot\/grub2\/grub.cfg<\/strong><\/p>\n

tras esto solo nos queda editar los ficheros ethX de toda la vida y ponerle los par\u00e1metros que queramos (entre ellos el par\u00e1metro <\/b>\u00abNAME\u00bb<\/b>) y ya tendremos los dispositivos renombrados con los nombres cl\u00e1sicos de Linux\/Unix<\/p>\n","protected":false},"excerpt":{"rendered":"
