I have several times lost SSH access to ONTAP 8.1 and 8.1.1 simulators. Things can work fine for several days but suddenly I am unable to login over SSH. I have the usual login prompt in PuTTY but the windows closes as soon as I enter the password. It is just like if someone else is logged in but I am sure nobody is. At the same time I have the following error message on the console of the sim:
[<hostname>:telnet.socket.timeout.warning]: Telnet daemon socket timed out for the SSHv2 connection.
Tried these without any success:
"logout telnet" (reports that no session is present)
"options ssh.enable off" + "...on"
"secureadmin setup -f ssh"
Rebooting the sim solves the issue. But that is not a solution. Not even worth calling a work-around.
