I'm unable to ssh into our fwsm today - there's nothing in the logs and all ssh commmands are still present - we've had this before and I have to re-generate the rsa key, and I'm fairly certain that's what I need to do now but the old ca commands that I used have been depreciated (fwsm 3.1) so I just wanted to check that I'm doing the right thing! Here's what I'm planning on:
crypto key zeroize rsa
WARNING: All RSA keys will be removed.
WARNING: All device certs issued using these keys will also be removed.
Do you really want to remove these keys? [yes/no]: yes
crypto key generate rsa general-keys modulus 1024
Does this look right?
Hmmmm, it can be a bug. I did some research and I found the following:
Maybe you can try to upgrade, or you can open a TAC case in order to further investigate.
