ASDM not working on ASA

Unanswered Question
May 14th, 2008

I have ASA 5550 VPN Premium license. But i am having strange problem with it. I am not able to do the ASDM from outside interface. I have no access-list no specific policy, from outside interface I am only able to do the SSH, even telent is not working.

There is no connectivity issue, Please help me out how to solve this problem.

i dont think this will fix your problem but you also seem to be missing the following config line:

aaa authentication http console LOCAL

the recent posted should have resolved your issue. Also make sure that you do a show disk0: and make sure that version 523.bin is actually in your flash as this is the version you are booting with

asdm image disk0:/asdm-523.bin

Try the line:

http EDNUplink

Also, I think that telnet is only allowed on the outside interface if it comes through a vpn tunnel. It requires encryption to be used on the outside interface and should show up in the logs as such with debugging logging on.

I have the same issue running 8.0(3) on an ASA5520, oddly enough, it works following a device reload, for a limited amount of time, and I also have oher ASAs with the exact same OS/management configuration, which I can access via ASDM fine.

Based upon this I am thinking it must be a hardware fault, or intermittent OS fault. I will let you know what I am able to find out. Please advise also, if you find a fix.

I too have the same problem, in the debugg appear:

HTTP: processing GET URL '/' from host

HTTP: redirecting to: /admin/public/index.html

HTTP: processing GET URL '/admin/public/index.html' from host

HTTP: authentication not required

HTTP: file not found: public/index.html}

Luis, what debug did you run, if I run a debug http, I dont get any output relating to this connection attempt...?

Also, FYI, I have downgraded back to ver8.0(2) as I never noticed this problem when using that code, I am currently running 8.0(3), but now I ge the problem running 8.0(2) also.
