Los routers Juniper disponen de una GUI para la gestión de dispositivos. Instalaremos esta función en un router JunOS en un laboratorio GNS3 para poder probar esta interfaz web.

Lo instalaré en un router que ejecute JunOS 12.1R1.9. Una vez que tengamos el paquete, recuerde que un router Junos tiene un sistema operativo BSD subyacente, por lo que el paquete será .tgz

Primero tenemos que configurar nuestro servidor TFTP en un ordenador accesible al router. No explicaré como conectar una red GNS3 con nuestra red física ya que es algo que hice anteriormente.

Vamos a conectarnos a nuestro servidor TFTP, recuerda hacerlo fuera de la CLI:

root@JUNOS5% tftp 192.168.66.100

Descargar el paquete JWeb:

tftp> binary  
tftp> status  
Connected to 192.168.66.100.  
Mode: octet Verbose: off Tracing: off  
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds  
tftp> get jweb-12.1R1.9-signed.tgz /var/tmp/jweb-12.1R1.9-signed.tgz  
Received 7770670 bytes in 28.6 seconds  
tftp> quit

Se le pedirá que reinicie la CLI, ya que se ha actualizado, no se preocupe con eso. Ahora vamos a habilitar la gestión web:

 It will ask to restart the CLI as it has been upgraded, no worries with
that. Now we will enable the web management:
