Routers

Juniper – Web interface is not responding

Juniper web interface is far from being great. It has it's faults but one of the most weird faults is that it stops responding after a while. Both http and https web access stop responding and only Telnet or SSH is available. While common fix to reboot the router is nice (as it can be done from SSH or simply by unplugging power) it's far from being quick usually taking 5 minutes to boot up. Fortunately there's a way.

Solution

If your JunOS interface isn't responding and you can access the SSH, telnet or console you can simply type 3 magic commands:

Enter CLI (Command Line Interface)

Enable editing of configuration

Restart Web Interface of JunOS

root@JuniperSRX2202% cli
root@JuniperSRX2202> edit
Entering configuration mode
root@JuniperSRX2202# run restart web-management
Web management gatekeeper process started, pid 2742

Simple, yet necessary to bring back web interface.

Notes

This router flaw is available in JUNOS Software Release [12.3X48-D30.7] and earlier.
Tested and confirmed on: Juniper SRX220H2
