Que tal gente para actualizar el firmware del juniper debido a algun brick o otro motivo por tftp hay que hacer lo siguiente.
Primero antes que nada tienen que tener instalado un servidor tftp (que no les voy a decir como se hace), y tienen que tener el firmware (en este caso un ex200).
bue… a comenzar
al iniciar el equipo te da la opcion de precionar espacio para poder entrar en el loader, una vez que estemos en el loader configuramos la ip del switch y del tftp-server

set ipaddr=192.168.100.2
set netmask=255.255.255.0
set serverip=192.168.100.1

despues conectamos un cable de red entre el puerto de management y nuestro servidor tftp, y comenzamos a instalar

install tftp://192.168.100.1/jinstall-ex-2200-10.4R5.5-domestic-signed.tgz

listo… dejar que suceda lo que tiene que suceder he’i y listo, ya les va a actualizar

despues de hacer esto ya les deberia funcionar.
(no les explico como ponerle la ip por que supuestamente si no pueden conectar es por que anteriormente ya le pusieron jajajaja)

Hay varias formas de conectarse al puerto de consola desde el linux…
yo utilizo un convertidor serial a usb para conectarme…
desde el linux podemos por supuesto utilizar el putty… (en el linux no me gusta el putty)…
o…
Podemos usar el minicom, este es el programa que mas se utiliza… en post anteriores y venideros voy a continuar colocando como utilizar…
Tambien, ultimamente estoy utilizando un programa que se llama picocom, este me gusta mas que el minicom
y el ultimo programa y el que mas estoy utilizando es el “screen”, si… este comando es espectacular… la forma de utilizar screen para conectarte al switch o router es… 

screen /dev/ttyUSB0 9600

esto es para las consolas de 9600 baud, en el caso que la velocidad sea mas rapida se le coloca la velocidad al final
entonces screen, dispositivo que queremos conectarnos y la velocidad..

happy linux

De las primeras cosas que hago en los juniper cuando voy a configurar es setear los valores a la interfaz de administracion (management Ethernet).
La interfaz de administracion es un punto de red que normalmente esta en la parte de atraz de los switch que es independiente a los demas puertos de la red, la forma de configurar es la siguiente:

set interfaces me0 unit 0 family inet address 192.168.1.1/24
set system services ssh
set system services telnet
set system services web-management http
commit

con eso y una maquina que esta en la misma red ya vamos a poder acceder a la interfaz web, telnet, ssh o cualquiera que le habilitemos.

bueno…
debido a que esto es el blog de mi6uel y no el blog de linux jejejeje voy a tener que moverme un chiqui e irme hacia otra parte que me gusta… el networking
laburo nuevo hardarware y software nuevo (por suerte lo que mas tocamos es juniper y esta basado por lo menos en freebsd jajaja)…
Hoy comienzo con un cambio de firmware de un switch juniper ex2200, este cambio creo que aplica a cualquier juniper que tengamos, debemos conseguir el firmware que querramos instalar, no les voy a decir como conseguir jejeje.
en inet hay muchos, bueno… yo bajo el firmware de la pagina juniper.net en este caso baje el firware jinstall-ex-2200-10.4R4.5-domestic-signed.tgz
Para actualizar primero debemos (no les voy a explicar tampoco como “todavia”) tener todo configurado nuestro switch (o sea tiene que tener ip) para poder copiar con scp (desde un linux).

scp jinstall-ex-2200-10.4R4.5-domestic-signed.tgz user@ip:/tmp/

el user@ip es el usuario y la ip de la maquina ehhhhh por ejemplo: scp jinstall-ex-2200-10.4R4.5-domestic-signed.tgz 192.168.1.1:/tmp/

con ese comando ya tenes copiado el firmware dentro de la carpeta /tmp de nuestro juniper

bue… una ves que tenemos copiado el archivo le damos el comando para comenzar a actualizar
