Juniper routers have a GUI for device management. We will install this feature to a JunOS router in a GNS3 lab so we can test this web interface.

I’ll install it in a router running JunOS 12.1R1.9. Once we have the package, remember that a Junos router has an underlying BSD OS, so the packet will be .tgz

First we have to configure out TFTP server in a computer accessible to the router. I’ll not explain how to connect a GNS3 network with our physical network as it’s something I did before.

Let’s connect to our TFTP server, remember to do this out of the CLI:

root@JUNOS5% tftp 192.168.66.100

Download the JWeb package:

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

Install downloaded package:

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

Now we can access the router using our browser:

Juniper WDM

From now on, you have to go on your own!
