ASA 5520 ASDM Launcher problem

olatunjitoheeb — Tue, 12 Jan 2021 16:19:56 GMT

I'm trying to login into my ASA 5520 ASDM IDM luncher, but when I put the ip address of the ASA, the username and the password into the ASDM launcher I'm getting "unable to launch device manager from 192.168.x.x.

can anyone help. I have read through the community solutions and everything being suggested did not work for me.

Please see the attached image of the message.

We need more information, what version of ASDM in the ASA , show version give information.

1. what java version available on your PC

2. have you setup http. ( change the IP as per the environment)

(config)# http server enable
(config)# http 10.10.10.0 255.255.255.0 INSIDE
(config)# username bandi password password privilege 15

https://10.10.10.10 << ASA IP to test working

You need to specify the ASDM image in your configuration. Use this command in config mode: "asdm image disk0:/asdm-752-153.bin" (based on the directory output you provided).

Also, once you fix that, please confirm that you are accessing ASDM from a host on the 192.168.2.0 subnet.

Your ASA is set to allow only access from there as a result of this configuration line: "http 192.168.2.0 255.255.255.0 local-lan".

When i tried to access the ASDM from java web start application i get the following also;

"Java Web Start is required to run ASDM, but it is not installed on this computer."

Though i already have java installed on the pc.

thanks for any useful idea.
