SSH behavior Weird

[hanwucisco]

ASA (outside)========ACS also, my PC.

Our ACS and my PC are both outside the ASA.

I can HTTP into the ASA with ASDM and ACS shows the records that I logged successfully.

But I can’t SSH through Putty from the same computer where I logged in with ASDM. I get error message from Putty " server unexpectedly closed network connection". The TCP connection torn down quickly as shown in ASDM Log. There is no any records for the failed attempt in ACS. And ACS has had nothing changed.

Any idea?

Thanks,

Han

On ASA, did you use "ssh" command to permit SSH access from your pc?

[hanwucisco]

The subnet where my PC is in is allowed, as shown in "show ssh"

[Yudong Wu]

can you run "debug ssh 255"?

Hi Han,

Could you please paste the output of:

sh run | in ssh

sh run | in aaa
