Secure Shell protocol 6 Setting up SCP for configUploads and downloads 1. Log in to the switch as admin. 2. Type the configure command. 3. Type y or yes at the cfgload attributes prompt. 4. Type y or yes at the Enforce secure configUpload/Download prompt. Example of setting up SCP for configUpload/download switch:admin> configure Not all options will be available on an enabled switch. To disable the switch, use the "switchDisable" command. Configure... System services (yes, y, no, n): [no] n ssl attributes (yes, y, no, n): [no] n http attributes (yes, y, no, n): [no] n snmp attributes (yes, y, no, n): [no] n rpcd attributes (yes, y, no, n): [no] n cfgload attributes (yes, y, no, n): [no] y Enforce secure config Upload/Download (yes, y, no, n): [no] y Enforce signature validation for firmware (yes, y, no, n): [no] 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: http://www.ietf.org/ids.by.wg/secsh.html For more information, refer to SSH, The Secure Shell: The Definitive Guide by Daniel J. Barrett, Ph. D., Richard E. Silverman, and Robert G. Byrnes. Fabric OS Administrator's Guide 105 53-1001336-01
