Logging Into the Switch

Using Secure Shell

The OmniSwitch Secure Shell feature provides a secure mechanism that allows you to log in to a remote
switch, to execute commands on a remote device, and to move files from one device to another. Secure
Shell provides secure, encrypted communications even when your transmission is between two untrusted
hosts or over an unsecure network. Secure Shell protects against a variety of security risks including the
following:
•
IP spoofing
•
IP source routing
•
DNS spoofing
•
Interception of clear-text passwords and other data by intermediate hosts
•
Manipulation of data by users on intermediate hosts

Secure Shell Components

The OmniSwitch includes both client and server components of the Secure Shell interface and the Secure
Shell FTP file transfer protocol. SFTP is a subsystem of the Secure Shell protocol. All Secure Shell FTP
data are encrypted through a Secure Shell channel.
Since Secure Shell provides a secure session, the Secure Shell interface and SFTP are recommended
instead of the Telnet program or the FTP protocol for communications over TCP/IP for sending file
transfers. Both Telnet and FTP are available on the OmniSwitch but they do not support encrypted
passwords.
Note. Secure Shell may only be used to log into the switch to manage the switch. It cannot be used for
Layer 2 authentication through the switch.

Secure Shell Interface

The Secure Shell interface is invoked when you enter the

the client and the server is complete, the remote Secure Shell interface runs in the same way as Telnet.

Secure Shell File Transfer Protocol

Secure Shell FTP is the standard file transfer protocol used with Secure Shell. Secure Shell FTP is an
interactive file transfer program (similar to the industry standard FTP) which performs all file transfer
operations over a Secure Shell connection.
You can invoke the Secure Shell FTP session by using the
using the sftp6 command in an IPv6 environment. Once the authentication phase is complete, the Secure
Shell FTP subsystem runs. Secure Shell FTP connects and logs into the specified host, then enters an
interactive command mode. Refer to
