DEFLATE compression is also supported. If this is enabled and negotiated, SSH packets are
first compressed before being encrypted and delivered to the remote unit via the TCP
socket.
Note:
The SSH server supports the SCP file copy protocol but does NOT support filename
wildcards.

(default 1).
Host Key 1 Filename
The value in this text box is the filename of either an SSH V1 or V2 host key. It is highly

easily accessed and compromised. This key may be generated using the facilities described
in the Certificates section of this manual.
Host Key 2 Filename
The value in this text box is the filename of either an SSH V1 or V2 key as above.
Note:
The maximum length for these filenames is 12 characters and they must use the DOS 8.3
file naming convention.
Maximum login time s seconds
The value in this text box specifies the maximum length of time (in seconds) that a user is
allowed to successfully complete the login procedure once the SSH socket has been opened.
The socket is closed if the user has not completed a successful login within this period.
Maximum login attempts n
The value in this text box specifies the maximum number of login attempts allowed in any
one session before the SSH socket will be closed.
Use Deflate compression No/Yes, level n
The radio buttons select whether or not DEFLATE compression will be used. If compression
is selected, the compression level is chosen from the drop-down list.
