Hi!


I'm trying to connect to my ASA but i always get this error:


"ASDM is unable to read the configuration from the ASA. Please check the configuration and your connection and then try again by clicking the Refresh icon."


This only appears after I do the login in Java application.


This is from my "show running-config":


asdm image disk0:/asdm-507.bin

http server enable

ssh my.ip.from.outside 255.255.255.255 outside

http my.ip.from.outside 255.255.255.255 outside


I really need some help...


Thanks and Bests Regards.

Hugo,


We've experienced the same error on computers updated to the latest JAVA patch:

JAVA 6 Update 10.


The problem does not occur on JAVA 6 Update 7, which we had installed previously.


Could be worth testing on a computer with the older release installed.

Hi!


show flash:

Initializing disk0: cache, please wait....Done.

243679232 bytes available (11747328 bytes used)


I already tried with:

asdm image disk0:/asdm-507.bin

and

asdm image flash:/asdm-507.bin


But I don't think that the problem is there, because I can get the Java application in my Browser. The error appears when I log on and when I hit the refresh button.


Thank you!

Hugo Serrano.

Hi Roger!


Thanks a lot! That was the problem.


I tried with Java build 1.5.0_16-b02 and worked!


Thanks again. Best regards,

Hugo Serrano.
