ASA5505 ASDM WON'T LAUNCH

Brett Erickson
Level 1
Level 1

I am at my witts end with this one and can't seem to find anything that matches my situtation. So I have an ASA5505 that I am trying to get the ASDM running on. I have done this before on other firewalls with no issue. Everytime I go to the url https://192.168.1.1 I get the prompt to accept the certificate which I do, then it just goes blank and the page freezes. If I try to launch it straight from the ASDM launcher it also just freezes. I have double checked my ssl encryption and made sure it has rc4-sha1 aes128-sha1 aes256-sha1 3des-sha1. I am using asdm-714.bin image and have tried getting it run on the asa 8.2.5, 8.4.7 and 9.1.3 code and get the same results with each version of code I put on this device. I have also tried multiple computers, and both computer connect to my other firewalls just fine via url to lauch asdm or asdm launcher so I know it isn't a java issue with them. Is there something I am missing?? I have tried accessing the url using Safari, Firefox, Chrome and IE, all with the same results, accept the cert and it just hangs there and never displays the asdm launch page. Please Help!

From customer:

Also I have tried power cycling the ASA, using a diffrent asdm image file, the image file "asdm-714.bin"

So it's a bug. I mean we clearly see the problem with the SSL Crypto Hardware Accelerator

Also I have tried power cycling the ASA, using a diffrent asdm image file, the image file "asdm-714.bin" I got straight from the cisco web site and I have put that image file on another ASA and it worked fine. I am so lost on this one, the debug isn't showing anything when I try to connect, it just keeps giving the;

HTTP: Periodic admin session check  (idle-timeout = 1200, session-timeout = 0)

Any ASA Ninja's out there have any idea what I should try next?

huh, there is some acl rule dropping it if i am reading this right, but i don't even have any ACL's configured on this ASA. I did a "wr erease" have have really only done the config to the point so I can't access the asdm.

Check my ARP, Connectivity post and provide results

Hello Brett,

Can you ping the Client PC from the ASA?

Do you see an ARP entry??

It seems like the packets are not even reaching the ASA bud.

Can you try from a different machine
