AUTOMATIC TRANSFER SWITCH
78
• Display the fingerprint of the SSH host key for SSH versions 1 and 2.
Most SSH clients display the fingerprint at the start of a session.
Compare the fingerprint displayed by the client to the fingerprint that
you recorded from the Web interface or control console of the
Automatic Transfer Switch.
From a command line interface, such as the command
prompt on Windows operating systems, you can use FTP or
SCP to transfer the host key file. You must transfer the file to
location /sec on the Automatic Transfer Switch.
If you do not specify a host key file, the Automatic Transfer
Switch generates an RSA host key of 768 bits, instead of the
1024-bit RSA host key that the Wizard creates. The
Automatic Transfer Switch can take up to 5 minutes to
create this host key, and SSH is not accessible during
that time.
If you are using SSH version 2, expect a noticeable delay
when logging on to the control console of the Automatic
Transfer Switch. Although the delay is not long, it can be
mistaken for a problem because there is no explanatory
message.
