Hiii Varun,

it's working perfectly, but why i can't connect via SSH or ASDM? i'm using my laptop and connect directly to interface 0/1 and SSH enable and i'm able to ping this interface. (also from ASA i can ping my laptop) but unable to access it via ASDM or even CLI "SSH"

can i know where else i need to check to access the device via ASDM? note that currently ASA software ver 8.4(3),  ASDM image: 6.4(7)

i still can access my ASA via console

please Advise

Hi Fadi,

Difficult for me to tell, but yes a few pointers that I can give:

Check "show run asdm", it should have the new ASDM image set asdm-647.bin...

Check "show run http", it shud have the correct settings.

For SSH:

Try "show run ssh", right configujration should be there.

Try generating the crypto keys again.

For ASDM, open the browser and type the url https://a.b.c.d    and then check.

Hope that helps.

Yes you can do that... no issues.

I suggest you can do it thru CLI as well using tftp client... that will be easier.....
