SDM stops on startup "Discovering router hardware attributes"

Hi, there I'm preparing for my CCNA Security and want to practice on SDM but unfortunately I can't open it.

My lab is Windows 7 Gns 3.7.4 Java 1.6.0_03 (it was told me that's the compatible one) IOS:  c3640-jk9s-mz.124-16.bin and SDM 2.5

My config is:

int fa0/0

ip address

no shut


ip domain-name router.com

username test privilege 15 password test

ip http server

ip http secure-server

ip http authentication local

line vty 0 4

login local

transport input telnet ssh

privilege level 15

line cons 0

login local

transport output telnet ssh

privilege level 15


crypto key generate rsa gen mod 1024


1. using http won't pop up anything can't run on http

2. using HTTPS passes the popup windows but stops at:

"Please wait while sdm is loading the current configuration from your router.  Discovering router hardware attributes."

As the picture shows:sdm.png

And then nothing happens.

I'm playing around with it for a few days, hands up have no more ideas what to do...if you have any ideas please share it - really wanna check the SDM before exam.

Can you try this command:

ip http timeout-policy idle 600 life 86400 requests 10000
