MAC MD5 preference (0= disabled):
MAC MD5-96 preference (0=disabled):
MAC SHA1 preference (0=disabled):
MAC SHA1-96 preference (0=disabled):
Each of the above four parameters may be used allocate a preference value to each of the
authentication methods. Each parameter, when set to a non-zero value, indicates the prefer-
ence level for that authentication parameter. The lower the value, the higher the preference
level. For example, if MAC SHA1-96 was the preferred method of authentication you would set
MAC SHA1 96 to 1 and the other parameters to 2 or more. If all of these parameters are set to
the same value, the unit automatically uses them in the following order: SHA1, SHA1-96, MD5,
MD5-96.
Debug output:
If you have problems in establishing an SSH connection, this parameter may be turned on to
enable debug information about the connection to be routed to the debug port.
Using Text Commands
From the command line, use the ssh command to configure or display SSH server settings. To dis-
play current settings for the SSH server enter the following command:
ssh <instance> ?
where <instance> is 0. At present there can only be one SSH server instance, i.e. 0, but the
instance parameter has been included to allow for future expansion.
To change the value of a parameter use the following command:
ssh 0 <parameter> <value>
