Secure Shell protocol
To ensure security, Fabric OS supports secure shell (SSH) encrypted sessions. SSH encrypts all
messages, including the client transmission of the password during login. The SSH package
contains a daemon (sshd), which runs on the switch. The daemon supports a wide variety of
encryption algorithms, such as Blowfish-Cipher block chaining (CBC) and Advanced Encryption
Standard (AES).
NOTE
To maintain a secure network, you should avoid using Telnet or any other unprotected application
when you are working on the switch.
The File Transfer Protocol (FTP) is also not secure. When you use FTP to copy files to or from the
switch, the contents are in clear text. This includes the remote FTP server's login and password. This
limitation affects the following commands:
supportSave -k
,
configUpload
,
configDownload
, and
firmwareDownload
.
Commands that require a secure login channel must originate from an SSH session. If you start an
SSH session, and then use the
login
command to start a nested SSH session, commands that
require a secure channel will be rejected.
Fabric OS v6.1.0 and later support SSH protocol v2.0 (ssh2). For more information on SSH, refer to
the SSH IETF Web site:
