RE: Access to ASA via SSH and ASDM

Ways I have fixed this in the past:

ASDM:

1. Confirm image and reupload.
2. Confirm http server enable and port. If doing webvpn you may have a port
conflict.
3. make sure you permit your subnet / interface.
4. A new one I found - newer ASA code adds in a line "ssl encryption des" -
you want to change it to "ssl encryption 3des"

SSH:
1. Confirm you have permitted your subnet / interface.
2. confirm ssh version
3. You may have to zeroize and regen your rsa key
4. There is a known bug with 8.4.1 (CSCtn75060). Fix is to reload, disable /
remove all SSH commands and re-add.

Hope that helps,
Travis

Subject: OT: Access to ASA via SSH and ASDM

Team,

We have a whole bunch of Cisco ASA 5500 firewalls being used at head end and
at branches and at times, I have noticed that I am unable to connect to one
of the remote devices via SSH and/or ASDM (it can't connect).
Apparently, rebooting the device does not help either. I was wondering if
anyone else has experienced this issue and if so, what is the best way to
resolve it? BTW, I don't have any remote console solutions for these
devices and have to get someone to console in to fix it but wondering if
there is a better way for me to take care of issue remotely or avoid all
together? Please let me know if possible. TIA.

Tony
